How to Choose the Impact Plate of Impact Crusher?

 Choosing the right impact plate (or impact liner) for an impact crusher is crucial to ensure the efficient operation of the crusher and to extend its service life. The impact plate directly affects the crusher's performance, including the crushed product's size and quality, energy consumption, and maintenance costs. Here are the key factors to consider when selecting an impact plate for an impact crusher:

                    

1. Material Type

Hardness of Material: The type of material being crushed greatly influences the choice of the impact plate. For hard, abrasive materials (like granite, basalt, or iron ore), the impact plate should be made of high-quality, wear-resistant materials, such as high-chromium cast iron or martensitic steel. For softer materials, a less durable plate may suffice.

Feed Material Characteristics: Consider the material's moisture content, size distribution, and abrasiveness. For example, sticky or wet materials may require different impact plates or crusher configurations to prevent clogging or excessive wear.

2. Material of the Impact Plate

High Chromium Cast Iron: This is one of the most common materials for impact plates due to its excellent wear resistance. It is ideal for crushing hard, abrasive materials.

Martensitic Steel: This material has a higher toughness than high chromium cast iron and is often used for secondary and tertiary crushing applications. It provides a good balance of wear resistance and fracture toughness.

Ceramic or Ceramic Composites: In some cases, ceramic coatings are used to improve wear resistance, especially in highly abrasive applications.

Hardfacing Materials: In some cases, the impact plates may undergo hardfacing or welding of wear-resistant materials to extend their life.

                   

3. Impact Plate Design

Thickness and Shape: The thickness of the impact plate can affect both the wear life and the crushing efficiency. Thicker plates may last longer but may also affect the overall performance of the crusher. The design should optimize material flow, minimize blockages, and enhance impact energy distribution.

Replaceability: Choose impact plates that are easy to replace and maintain. This helps reduce downtime during maintenance and ensures the crusher continues to operate at peak efficiency.

Angle and Position: The angle at which the impact plate is positioned within the crusher affects the trajectory and impact of the material being crushed. Proper alignment and design can lead to more efficient size reduction and fewer blockages.

4. Wear Resistance and Durability

Wear Rate: Consider how quickly the material will wear the impact plates. In high-wear applications, the impact plate material should have high hardness and impact resistance.

Reversible Plates: Some impact plates are reversible, meaning they can be turned around and used on the other side to double their useful life. This is a cost-effective feature in some cases.

                     

5. Cost vs. Performance

There is a trade-off between the cost of the impact plate and its performance. While high-quality, durable materials may have a higher initial cost, they can save money over time by reducing the frequency of replacements and improving operational efficiency.

6. Environmental and Operating Conditions

Temperature: Operating temperature can influence the material choice. In very high or low temperatures, certain materials may become more brittle or less resistant to wear.

Operating Speed: High-speed crushers may require impact plates that can withstand more intense impact forces. The plate material should be selected to match the specific operational conditions.

                     

When choosing the impact plate for an impact crusher, the material type, durability, design, and cost all play significant roles. For harder, more abrasive materials, wear-resistant materials like high chromium cast iron or martensitic steel are recommended. It is essential to balance cost with performance, considering factors like the wear rate, ease of replacement, and specific operating conditions to ensure efficient and long-lasting operation of the crusher.

Types of Gold Ore Crushers and Prices-Vanguard Machinery Tech

Gold ore refers to gold-containing ore mined from mines by hand or machine, which also contains other metal impurities. After crushing, it is applied to electronic instruments, electrical, chemical, powder metallurgy and other industrial fields. However, which gold ore crushing equipment is better? Here is a detailed introduction to the types, prices and other contents.

                          

1. Types of gold ore crushers

Gold ore is often in irregular granular, lump, flake, mesh, dendrite, fiber and sponge aggregates, and its hardness is usually between 2-4. Specifically, the hardness of natural gold is about 2-3, while the hardness of deep gold ore can reach 4.5. These data show that it is relatively soft and can be processed with relatively simple equipment, so using the jaw crusher and cone crusher is better. The specific factors need to be considered comprehensively according to capacity, discharge size requirements, working conditions and other factors.

1). Jaw crusher

                       

As primary crushing equipment, it is often used for coarse crushing large pieces of ore. Its core components are a pair of movable jaw plates (moving jaw) and fixed jaw plates (fixed jaw). The eccentric shaft driven by a motor makes the movable jaw do periodic reciprocating motion, forming an extrusion and splitting effect on the material to complete the work. The deep V-shaped crushing cavity and the absence of dead zones improve efficiency and ensure uniform particle size of the final product. At the same time, wedge blocks are used to adjust the discharge port, which is easy to adjust and maintain.

2). Cone crusher

                        

It has a better effect on the fine crushing of ores. Its working principle is based on the mutual extrusion between the internal moving cone and the fixed cone. Different cavity types can be selected according to different needs to better meet user needs. The product particle size can be controlled by adjusting the size of the discharge port. It has a large crushing force, high efficiency, strong wear resistance, perfect overload protection, easy automatic control, and can effectively reduce the damage of non-crushed objects to the equipment.

2. How much is the price of a gold ore crusher?

There are differences in the price of gold ore crushers. Currently, the price in the market ranges from hundreds of thousands to millions of yuan. How to choose, in addition to the model, type and capacity, there are many manufacturers now. The raw materials, design, technology, etc. used in manufacturing equipment will cause quality changes, so it is also necessary to examine the quality and use effect, as well as other aspects.

The specific price of the gold ore crusher is subject to the manager's provision. Welcome to learn about the accurate and effective factory preferential quotation. In addition, Vanguard Machinery has established a modern testing base. The raw materials and workmanship are rigorous, and the quality is more guaranteed. You can come to the factory and workshop for on-site inspection at any time. For each customer, there is a technical team to provide installation, debugging, technical training and other after-sales services. 

What Is the Reduction Ratio of the Crusher?

 When purchasing crushers, especially jaw crushers for coarse crushing, we often see a word: large reduction ratio. So, what is the reduction ratio of the crusher? What are the commonly used calculation methods?

What is the reduction ratio of the crusher?

    After the ore is blasted, there are mostly large stones of different sizes. They must be crushed by the crusher before they can meet the needs of the project. So do these stones need single-stage crushing or multi-stage crushing? The reduction ratio is a very important factor.

The reduction ratio refers to the ratio of the feed particle size to the product particle size in the crusher, which indicates the degree of material crushing, which directly affects the energy consumption and processing capacity of the crusher.

Commonly used calculation method of reduction ratio

    The reduction ratio has a professional calculation method, which is divided into three types according to different situations:

1. Particle size reduction ratio:the ratio of large block size before and after crushing

Calculation formula:I = larger diameter of feeding material / larger diameter of finished product

    Due to the different habits of each, the large-granularity value method is different. British and American take the sieve width at which 80% of the material can pass through the sieve hole as the large particle size diameter. China and the Soviet Union, 95% of the material can pass through the sieve hole width as the diameter of the large particle size.

Application object:This calculation method is often used in quarries because the width of the feed port of the crusher should be determined according to the large particle size of the ore in the design.

2. Surface reduction ratio:the ratio of the width of the crusher inlet to the width of the outlet

Calculation formula:I=0.85B/S (inlet width/discharge width referred to here)

0.85 is the width coefficient of the crusher to accommodate the material. The value S of the width of the discharge port: the coarse crusher is different from the medium and fine crusher, and the former takes the larger width; The latter takes the smaller width.

Application object:Because this method does not need to do screening analysis of a large number of materials, the approximate calculation can be carried out until the width of the feed port and the discharge port of the crusher, which is simple and fast, so it is widely used in production.

3. Average reduction ratio:the ratio of the average particle size of the material before and after crushing.

Calculation formula:I=average particle size of material before crushing/average particle size of material after crushing

Application object:Because the size and shape of the ores before and after crushing are different, they can only be represented by the average particle size. Therefore, the crushing ratio calculated by the average particle size can reflect the degree of crushing more truly, so it is mostly used in theoretical research.

    In actual production, the appropriate calculation method of the reduction ratio should be selected according to the specific work content of the crusher.

Winter Guardian: Tips on the Care and Maintenance of Mining Equipment in Low-temperature Environments

 As the core equipment in the production process, the crusher's stable operation is crucial to the entire mining operation. Especially in the cold winter, problems such as the solidification of lubricating oil, hardening and wear of lubricating parts, and difficulty in starting equipment frequently occur, which brings considerable trouble to mining production. This article aims to reveal to you the core maintenance strategies of mining crushers in low-temperature environments, ensuring that the equipment operates stably and efficiently in severe cold, and safeguarding mine production.

1. Selection of lubricating oil and solution to solidification problems

(1). Lubricating oil selection:

In low-temperature environments, low-temperature lubricating oil should be selected. Their viscosity changes less with temperature and has better fluidity at low temperatures. They can effectively prevent solidification and ensure that equipment is effectively lubricated and protected in low-temperature environments. Extend the service life of the equipment and improve the reliability and stability of the equipment. Common low-temperature lubricating oils include winter-type engine oil, grease, etc. In actual applications, appropriate low-temperature lubricating oil products are selected based on the specific working conditions, ambient temperature and requirements of the equipment.

(2). Solve the problem of lubricating oil solidification

1) Choose low-temperature lubricating oil to ensure that it still has good fluidity and lubrication performance in low-temperature environments;

2) During the operation of the equipment, the oil temperature adjustment device or preheating system is used to keep the lubricating oil temperature within an appropriate range to avoid solidification caused by too low oil temperature;

3) Regularly clean the oil and dust on the surface of the equipment and check the lubrication system regularly to prevent impurities and pollutants from entering the lubrication system, ensure smooth pipelines, and prevent lubricating oil from solidifying in the pipelines and causing blockage;

4) According to the usage of the equipment, replace the lubricating oil regularly. This can prevent the lubricating oil from aging, being contaminated or mixed with impurities, and maintain its good lubrication performance and fluidity.

2. Solve the hardening and wear problems of lubricating components

In low-temperature environments, the brittleness of materials increases, which can easily lead to hardening and wear of lubricating components, such as bearings, gears, bearing bushes, etc. This not only affects the normal operation of the equipment but may also cause malfunctions and even interrupt production. Therefore, we must attach great importance to the maintenance of lubricated components in low-temperature environments.

For the hardening and wear challenges of lubricated components, the following solutions may be considered:

(1). Lubrication and cooling: Ensure that the lubricating components of the equipment are fully lubricated during operation to reduce friction and wear. In addition, in low-temperature environments, the selection and supply of lubricating oil should be appropriately adjusted to ensure the lubrication effect.

(2). Regular maintenance and replacement: Regular inspection, cleaning and maintenance of lubricating components. According to the usage and wear degree, damaged or severely worn lubricating components should be replaced in time to ensure the normal operation of the equipment. At the same time, sufficient spare parts should be stored in advance to ensure timely supply when lubricating components need to be replaced. In addition, according to the operating conditions of the equipment, promptly adjust the position of the lubricating parts and the tightness of the fasteners to ensure that they are in good working condition.

(3). Choose high-quality products and services: Choosing strictly verified lubricating component products can provide stable support for mining equipment under harsh conditions and ensure production continuity and stability. At the same time, choosing a professional mining equipment maintenance and maintenance service team can provide comprehensive technical support and guarantee.

3. Solving difficulties in starting equipment

In low-temperature environments, mining equipment often faces huge challenges during the start-up phase, mainly due to several key factors: the significant increase in lubricating oil viscosity and the too-low temperature of the motor, resulting in a significant increase in resistance when the equipment is started, thus causing It is difficult for the equipment to start and operate normally, which not only affects production efficiency and equipment performance but may also increase maintenance costs and safety risks.

The following are several solutions to the problem of difficulty in starting mining equipment in low-temperature environments:

(1). Select lubricating oil suitable for low-temperature environments to ensure that key parts of the equipment are well lubricated and effectively reduce the friction resistance of key parts of the equipment, thereby ensuring smooth start-up and operation of the equipment;

(2). In a low-temperature environment, too low a temperature of the motor may cause startup failure. The motor can be preheated in advance to reach a suitable operating temperature to ensure that the equipment can start smoothly.

(3). Install heating equipment or use insulation measures to increase the overall temperature of the equipment and reduce starting resistance. These measures will help reduce the viscosity of the lubricating oil and ensure that the motor operates at a suitable temperature.

Facing the challenge of low-temperature environments, mining equipment will always encounter many problems, but as long as we adopt professional solutions, we can easily solve these problems. Through professional and reasonable operation and maintenance, we ensure that mining equipment can successfully cope with various extreme conditions and maintain stable and efficient operation, providing solid technical support and guaranteeing the continuous and safe production of mines.

What is the Sand Production Rate of Granite Sand Making? How is the Granite Sand Making Production Line Configured?

 Granite is a hard igneous rock, mainly composed of quartz, feldspar, mica and other minerals. Its Moh's hardness is 5-7 with high strength, corrosion resistance, wear resistance and other properties. After sand making treatment, granite can be made into sand with excellent grain shape and uniform particle size. This kind of sand is an important construction material that can meet the demand for high-quality aggregates in engineering construction and also provides a reliable material basis for various engineering projects. In this article, we will discuss sand production rates, influencing factors, and typical production line configurations for granite sand production.

1. Sand production rate and influencing factors of granite sand making

The sand production rate of granite sand making is mainly affected by factors such as rock properties, rock size, crushing methods, and sand making equipment. According to relevant literature reports, the sand production rate of granite sand making is generally between 30% and 50%, that is, each ton of granite can produce 0.3-0.5 tons of sand. However, actual sand production rates may vary due to various factors.

Among them, the properties of rocks such as hardness and toughness have a great influence on the sand production rate, while the crushing method and sand making equipment can increase the sand production rate by selecting appropriate models and parameters.

(1) . Hardness and toughness

Generally speaking, the higher the hardness of granite, the more difficult it is to crush with the relatively low sand production rate. The harder and less tough granite is easier to crush with the relatively high sand production rate.

(2) . Rock size

The size of the rock is an important factor affecting the sand production rate. Generally, the larger the particle size of granite, the more difficult it is to crush. It requires greater crushing force and grinding force to crush it into sand and with a relatively low sand production rate. If with too large granite particles, it will increase equipment wear and energy consumption and reduce production efficiency. Therefore, in the process of making granite sand, granite of appropriate size needs to be selected as raw material according to the actual situation.

(3) . Other mineral content

The content of other minerals in granite will also affect the sand making effect. For example, if it contains higher amounts of mica, feldspar, quartz and other minerals, it may reduce the sand production rate.

2. Granite sand making production line configuration

The granite sand making production line configuration usually includes a feeder, vibrating screen, jaw crusher, cone crusher, sand making machine, sand washing machine and other equipment. When configuring the granite sand making production line, it needs to be based on the capacity requirements, raw material characteristics, product requirements and other circumstances to select the appropriate equipment model. For example: for projects with small capacity and small material particle size, you can choose a fine jaw crusher to replace the cone crusher for secondary and tertiary crushing for medium and fine crushing; For projects with large capacity, then a cone crusher is needed to meet the capacity of thousands of tons/hour. Of course, budget is also an important factor to consider when configuring a granite sand making production line. If the budget is insufficient, other configurations can be selected to meet production needs.

Live video:

In the granite sand making production line, it also needs to be reasonably laid out. More crushing and less grinding links can be set up according to the actual situation. Production efficiency can be improved by adding equipment such as crushing equipment and fine sand recycling devices to achieve efficient and stable production. The specific configuration needs to be adjusted according to the actual situation. For example, if you need to produce finer sand, you may need to add sand making and sand washing links; If you need to increase the sand production rate, you may need to add crushing and sand making links. In addition, depending on the production scale and operation mode, fixed or mobile sand making machines can be selected to meet different production needs.

To sum up, when designing a granite sand making production line, you need to pay attention to several key points, including understanding the characteristics of granite, determining capacity, optimizing the process, selecting appropriate equipment, considering environmental protection factors, ensuring production safety, and considering investment costs and returns, etc. Reasonable equipment selection and parameter settings can increase the sand production rate, reduce production costs, improve production efficiency, and achieve the goal of sustainable development. Therefore, when designing and constructing a granite sand making production line, various factors should be fully considered and appropriate equipment models and parameters should be selected to achieve good production results.
