9 Major Differences Between Circular Vibrating Screen and Linear Vibrating Screen

Introduction

There are many types of vibrating screens. According to the movement trajectory of the material, they can be divided into circular vibrating screens and Linear vibrating screens. Both types are commonly used screening equipment in daily production. Today we will compare and see the difference between the two.

Classification of vibrating screens

According to the material movement trajectory of the vibrating screen, it can be divided into:

Linear vibrating screen: The material moves forward in a straight line on the screen surface;

Circular vibrating screen: The material moves forward in a circular motion on the screen surface.

There is no essential difference in the style and structural composition of the circular vibrating screen and the linear vibrating screen. The material is screened by the vibration of the screen surface, but the different vibration tracks will directly affect the purpose of screening.

Working principle

1. Circular vibrating screen

The motor drives the eccentric block of the vibrator to rotate at high speed through the V-belt, generating a large centrifugal inertia force, which stimulates the screen box to produce a circular motion with a certain amplitude. The material on the screen is subjected to the impulse transmitted by the screen box on the inclined screen surface and produces a continuous throwing motion. When the material meets the screen surface, particles smaller than the screen hole are screened, thereby achieving classification.

2. Linear vibrating screen

Using the vibration motor as the vibration source, the material is thrown up on the screen and moves forward in a straight line. The material enters the feed port of the screening machine evenly from the feeder and passes through the multi-layer screen to produce several specifications of oversize and undersize, which are discharged from their respective outlets.

Differences and comparisons

1. Movement trajectory

The material on the circular vibrating screen moves in a circular motion, and the material on the linear screen moves forward in a linear motion.

2. Exciter

The circular vibrating screen is also called a single-axis vibrating screen because the exciter is a single shaft and works by an inertial motor. The linear vibrating screen exciter consists of two shafts and works by the principle of vibration motor excitation, so it is also called a double-axis vibrating screen

3. Blockage phenomenon

The material on the circular vibrating screen moves in a parabolic circular trajectory on the screen surface, so that the material is dispersed as much as possible, thereby increasing the material bounce force, and the material stuck in the screen hole can also jump out, reducing the blockage phenomenon.

4. Installation layout

The linear vibrating screen reduces the screen height with a small screen surface inclination angle, for convenience for the process layout.

5. Screen surface inclination angle

According to the particle size of the material, the circular vibrating screen can change the screen surface inclination angle, thereby changing the material movement speed along the screen surface and increasing the processing capacity of the screen machine. Generally speaking, the linear vibrating screen has a small screen surface inclination angle in production.

6. Material

Generally speaking, the thicker plates use circular vibrating screens, and the box is made of manganese steel to resist the impact of materials during the screening process. The main materials of linear vibrating screens are made of light plates or stainless steel plates.

7. Applicable fields

Circular vibrating screens mainly screen materials with high specific gravity, large particles, and high hardness. They are widely used in mining industries such as mines, coal, and quarries.

Linear vibrating screens mainly screen fine particles, light specific gravity, and low hardness materials, especially for dry powder, fine particles or micro powder materials, and are usually widely used in food, chemical, building materials, and pharmaceutical industries.

8. Processing capacity

For the circular vibrating screen, since the exciter is arranged above the center of gravity of the screen box, the elliptical long axes at both ends of the screen box form a downward eight-shaped shape, and the upper end of the elliptical long axis at the feeding end faces the discharge direction, which is conducive to the rapid dispersion of the material, while the upper end of the elliptical long axis at the discharge end faces the discharge direction, which reduces the material movement speed and is conducive to the screening of difficult-to-screen materials. The arc-shaped screen surface also increases the effective area of the screen machine, thereby improving its processing capacity.

In addition, for difficult-to-screen materials, the circular vibrating screen can flip the main shaft, so that the vibration direction is opposite to the material movement direction, and the material movement speed along the screen surface is reduced (when the screen surface inclination angle is the same as the main shaft speed) to improve the screening efficiency.

9. Environmental protection

The linear vibrating screen can adopt a fully enclosed structure, without dust spillage, which is more conducive to environmental protection.

In the field of mining crushing, it widely used circular vibrating screens. In actual production, the choice of the circular vibrating screen or the linear vibrating screen mainly depends on the type of materials processed by the user and the application field. The different purpose of screening is to select different equipment.

What to do if there is too much Stone Powder in Machine-made Sand? 6 Ways to Control Stone Powder

 Four forms of stone powder in machine-made sand:

(1) Free powder: Stone powder particles do not adhere to each other or adsorb on the surface of sand and can move freely under the action of wind and gravity.

(2) Agglomerated powder: Stone powder particles are tightly aggregated together to form larger stone powder agglomerates, and the particles adhere to each other and aggregate. This type of stone powder aggregate is difficult to remove by traditional powder classification equipment due to the large particle size and mass of the agglomerates.

(3) Adherent powder: Stone powder particles are attached to the surface of larger sand particles. When the surface of the sand particles is relatively smooth, the stone powder particles are easy to remove under mechanical force, but when the surface of the sand particles is uneven, the stone powder particles and the sand particles tightly adhere to each other, and it is difficult to separate them by general mechanical methods.

(4) Cracked powder: There are often some natural cracks on the surface of sand particles, which are tens to hundreds of microns wide or generated by mechanical crushing. These cracks are often filled with a large number of stone powder particles. This is the most compact way of stone powder adhesion.

Stone dust control technology

The 6 types of stone dust control technologies and equipment are as follows:

1. Feeding vibrating grate screen

The increased mud content in machine-made sand will increase water demand and affect the strength of concrete, thus affecting its compression capacity. Therefore, before the raw materials enter the sand making process, they need to be sifted and discarded, which can significantly reduce the moisture content of the raw materials.

According to different material conditions, select the appropriate screen bar spacing to achieve different mud removal effects; For working conditions where the mountain bark is thick, the vegetation is difficult to remove, the mountain is severely weathered, and the interlayer contains large amounts of mud, which is easy to mix with soil, increasing the spacing between screen bars can effectively reduce the mud content.

2. Aggregate chute powder removal device

A certain specification of aggregate from the screening machine enters the aggregate unloading chute after the screening. An integrally detachable diffusion air distribution chamber is arranged in a suitable place, and the blower is connected to it. In this way, the free dust on the aggregate surface is blown up by the blower when passing through the chute and is collected in the dust collector under the suction effect of the dust collector.

In addition, the suction volume of the dust collector can be controlled by adjusting the pipeline regulating valve. When the blower adopts the variable frequency form, the ratio of blowing and suction is adjusted by the variable frequency control of the blower and the adjustment of the regulating valve, to realize the continuous control of the powder content of the finished sand and gravel aggregate within a certain range.

3. High frequency vibration screening pretreatment

Basic principle: The machine-made sand is preprocessed by high-frequency vibration to disperse the powder, separate the powder, coarsely and finely classify the sand, and then remove the stone powder contained by the wind.

Specific method: After the material is crushed by the sand making machine when it enters the screening module, it can be bulked through the bulker or the spiral material lever. This has a preliminary dispersion effect on the agglomerated and adhered stone powder and improves the quality of the material. The uniformity of distribution, at this time, the stone powder can be selected through the air separation device. After primary classification, the materials enter a high-frequency vibrating screen with a vibration frequency of 60-80HZ and an amplitude of 0.15-2.4mm for screening. The vibration intensity of this equipment is 3.5-5 times that of ordinary equipment, which can generate greater mechanical force and has a good dispersion and separation effect on agglomerated stone powder and surface-adhesive stone powder. At the same time, the coarse and fine classification of machine-made sand is efficiently achieved.

Compared with ordinary vibrating screens, the powder removal efficiency of machine-made sand after being screened by high-frequency vibrating screens is significantly increased by about 40%, and the required air volume is reduced by 45%.

4. Centrifugal powder classifier

The powder classifier is used in the sand making process. Its main function is to separate excess stone powder and useful particles and recycle them separately.

Its working principle is: to mix gas and powder to form a gas-solid two-phase flow. The rotating scattering disc and high-speed airflow make the powder-containing airflow obtain centrifugal force during rotation. The centrifugal force obtained by particles of different particle sizes is different, thereby realizing the separation of coarse and fine powder particles. At the same time, the coarse and fine powder particles are recycled separately by corresponding methods. The useful particles are the finished sand, and the useless fine powder is the waste material.

From the position of the powder separator installed in the building station, it is divided into raw material powder classifier and finished material powder selection process layout. The powder classifier has strict requirements on the moisture content. When the moisture content of the feed is higher than 5%, the powder removal efficiency of the powder separator will be seriously reduced. When the moisture content of the feed is 2%, the powder separator can better exert its efficiency, and the sand formation rate is between 60%-70%.

5. V-type static classifier + dynamic high-efficiency classifier

The raw materials enter the sand making machine, and after vibration screening, the coarse powder returns to the sand making machine, and the fine powder is sent to the combined classifier of the V-type static classifier + dynamic high-efficiency powder classifier. After being homogenized by the material distributor, it enters the classification system, the coarse particles enter the finished product warehouse, and the fine particles and fine powder enter the dynamic classifier with airflow. By adjusting the speed of the dynamic powder selector, the sand and gravel classification is adjusted, and the qualified products are discharged from the coarse powder pipe into the finished product warehouse. Adjust the particle grading of the finished product, and the fine powder is collected by the cyclone dust collector with the airflow and enters the stone powder warehouse. The airflow enters the V-type air inlet through the circulating blower.

6. Air Screen

The air screen combines wind separation technology based on vibration screening to realize the three functions of particle size adjustment, grading and screening.

Its working principle: The material is evenly spread under the action of the air screen dispersion device and blown to different positions of the air selection chamber by the blower. The lighter the material (the smaller the particle size), the farther it is blown away and the longer the screening distance; The lightest stone powder will be blown to the powder outlet position, adsorbed by the dust collector-induced draft blower, and finally concentrated in the powder tank. At the same time, the particle size adjustment plate automatically adjusts the proportion of the returned material to fine-tune the fineness modulus of the finished sand, thereby ensuring the stability of the fineness modulus of the finished sand.

For the dry sand making system using an air screen, the raw materials need to control their moisture content below 1.6% (surface moisture content 0.6%), without mud, and the feed particle size is 0-25mm and the gradation is continuous. If the raw materials change, the system capacity will change accordingly. If the raw materials contain too much mud or stone powder, separation processes such as powder classifier or powder removal equipment need to be used in the front stage.

Why Choose Basalt As The Raw Material For Crushing? How To Configure The Complete Crushing Production Line?

The rock structure of basalt often has stomata, an almond-like structure, and a porphyritic structure. The common color is mostly black, dark brown, or dark green, and it is one of the common types of stone on land. Because of its excellent material, it is selected by many crushing production lines to produce high-quality sand and gravel aggregates. So why choose basalt? How to configure a complete sand and gravel production line?

Why choose basalt?

After the processing of the crusher, the porous basalt sand and gravel can be mixed into the concrete, which reduces the weight of the concrete and has the characteristics of firmness, sound insulation, and heat insulation. It is a good aggregate for lightweight concrete in high-rise buildings. In addition, because basalt stone has the advantages of wear resistance, low draft, poor electrical conductivity, strong compression resistance, low crushing value, strong corrosion-resistance, and asphalt adhesion, it is the best material for repairing roads, railways, and airport runways.

How to configure the basalt crushing production line?

Take the customer's crushing production line of Vanguard Machinery in the Philippines as an example

Production line configuration: Vibrating feeder + Jaw crusher + Cone crusher + Vibrating screen

Raw material: Basalt

Capacity: 100T/H

Project overview: The basalt is uniformly sent to the jaw crusher by a vibrating feeder for primary crushing. The cast steel frame and movable jaw can easily crush the high-hardness basalt. The coarsely crushed basalt is transported by a belt conveyor to the cone crusher for further processing. The unique structure and working principle can effectively and finely crush the basalt, and at the same time, there are fewer downtimes for maintenance than the counter crushing, which improves the stable production progress. After being finely crushed, the basalt aggregate is sent to a vibrating screen, the finished aggregates of different specifications and returned materials are screened out, and the unqualified basalt is returned to the cone crusherfor further processing.

A reasonable configuration of a basalt production line can not only effectively crush stone, increase the capacity and quality of aggregate, but also reduce unnecessary wear parts loss, help investors recover their investment as soon as possible, and make profits. As a manufacturer of various types of high-quality crushers, Vanguard Machinery Tech Co., Ltd has made extremely high achievements in production technology and standards, and can scientifically customize basalt crushing production line programs for investors to meet the needs of high-quality aggregates in different markets. What's more, our complete after-sales service system can solve your worries.

What Are The Advantages Of Making Sand From River Stone? How To Configure A Perfect River Stone Sand Production Line?

 What Are River Stones

river stone is a hard, wear-resistant, stable chemical properties of silicate minerals, the river stone sand from natural river stones after crushing, sand making, screening, and a series of processing is an important industrial mineral raw materials, which is widely used in the field of engineering water conservancy and hydropower, high-grade road, highway, high-speed railway, passenger dedicated line, bridge, airport runway, municipal engineering, high-rise building sand production, and stone shaping. Pebble sand is also widely used as aggregate for concrete. In recent years, rivers stone as raw material processing of fine machine-made sand has also received high standards of manufacturers of affirmation and recognition!

In addition to Riverstone, granite, limestone, quartz sandstone, basalt, and even construction waste can be used to process machine-made sand. Why are pebbles still so attractive? What are its main advantages?

 

1. river stones are widely distributed, rich in resources, easy to mine, and low in mining costs, which can meet the needs of large-scale production.

2. river stones are hard rock, and their Platts hardness level is generally 2-3, the hardness coefficient is f=10-15, the texture is hard, compression, wear resistance, and corrosion resistance are strong.

3. With pebbles as raw materials for processing machine-made sand, the amount of stone powder in the production process is relatively small, and the material is stable, the performance is good, and the quality of the finished product is easy to control.

4. The machine-made sand made of river stones has excellent quality and stable performance. It is the preferred construction sand for high-rise buildings, highways, municipal engineering, water conservancy and hydropower, bridges, and other infrastructures.

The advantages of pebbles are the reasons for their popularity, but in order to process high-quality machine-made sand, it is particularly important to choose the right production equipment!

In general, sand making from river stone requires four steps: feeding, coarse crushing, fine crushing, and sand making. Because river stone is large in size, it needs to go through coarse crushing, medium and fine crushing, and sand making. In the link, there is a variety of equipment to choose from. The main equipment that needs to be used is a jaw crusher, impact crusher, and sand making machine. The auxiliary equipment includes a feeder, conveyor, and vibrating screen. If the local environmental protection is strict, dust and noise reduction devices are also required.

Main Equipment For Sand Making From River Stone

Coarse Crushing Equipment

Jaw crusher. The feeding size is large, which can meet the crushing of 125-1500m materials, and the output size is 10-350mm. It is commonly used for coarse crushing of materials, and it can also be combined with two pieces of equipment for medium and fine crushing. The equipment structure is simple and the crushing efficiency is high.

Medium And Fine Crushing Equipment

The cone crusher can be used for medium and fine crushing of river stones with high material hardness. Most of the materials after crushing are cube-shaped, and the feeding size should be smaller than 560mm. The equipment has the advantages of simple structure, low cost, and large output.

Sand making equipment: 5X series sand making machine, VSI series sand making machine and mobile sand making machine are all common sand making machine equipment. They each have their own advantages. They can crush river stones into sand that meets the requirements, and the sand making effects are better.

Sand Washing Machine Equipment

The sand washing machine is mainly responsible for the end of the sand production line. It’s used to remove impurities such as mud on the surface of machine-made sand. Through the sand washing procedure, the quality of machine-made sand will be better and the corresponding market value will be higher.

Vibrating Screen

A vibrating screen is a relatively common screening equipment, which can screen various stones and screen out finished products of different particle sizes. Generally, there are three-layer and four-layer screens, which are mainly used in the sand production line to form a cycle operation with the sand making machine.

Feeder And Conveyor

They are two auxiliary equipment in the production line, but they are also indispensable. The feeder is generally used before the jaw crusher, and the conveyor is the connecting tool between the main equipment of the entire production line.

 

The combination of that main equipment is a sand production line. Specific model adaptation needs to be configured according to various requirements such as production capacity, electricity consumption, and finished product granularity.

Process Flow Chart Of River Stone Sand Production Line

A reasonable combination of equipment and process can increase the overall benefits. Therefore, when developing the river stone sand making process for users, Vanguard mechanical engineers will first focus on understanding the customer's output, the requirements of the finished product, the surrounding environment, and whether it is a short-term trial operation or a long-term operation and so on. These are related to the investment cost and payback period.
