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.

A Detailed Explanation of the 7 Differences Between Cone Crusher and Jaw Crusher in Fine Crushing

 In the stone crushing production line, the reasonable configuration of crushing equipment plays a crucial role in increasing production and improving the stone shape and particle size distribution. Currently, the entire crushing production line process includes three main stages: coarse crushing, medium and fine crushing, and screening. In the fine crushing stage, there are many crushers to choose from. What kind of equipment is more suitable?

The structure and principle of the fine jaw crusher are similar to those of the jaw crusher. The working mode is the flexural extrusion type. The materials are squeezed and crushed in the crushing chamber composed of a movable and fixed jaw. The cone crusher adopts laminated crushing. The mortar wall continuously moves toward the crushing wall to squeeze the materials sandwiched between the two and crush them.

The difference between the two in actual production:

1. Production characteristics

Generally speaking, fine jaw crusher and cone crusher have the following characteristics:

1) The feed particle size range of the fine jaw crusher is relatively large, and it can generally process materials below 1000mm, while the cone crusher is relatively strict, generally requiring less than 300mm (depending on the specific situation of the product);

2) In terms of processing capacity, the cone crusher far exceeds the fine jaw crusher, generally up to 1000 t/h, more than twice that of the fine jaw crusher;

3) In processing hard materials, the compressive strength of the two is the same, between 300-350Mpa.

2. Overall structure

From the overall structure, the cone crusher is 1.7-2 times heavier than the fine jaw crusher with the same feed size, and the body is generally 2-3 times higher than the fine jaw crusher, so with a relatively large construction cost of the plant.

3. Processing materials

The cone crusher is not applied for crushing wet and sticky ores, while the fine jaw crusher can process almost all kinds of materials.

4. Feeding requirements

The cone crusher can be filled with ore and directly fed without adding silo and feeders. However, the fine jaw crusher cannot be filled with ore and requires uniform ore feeding, so it is necessary to set up additional silos and feeders, which increases the investment cost of auxiliary equipment.

5. Finished product particle shape

The finished products of the cone crusher are more needle-shaped, and compared with the fine jaw crusher, the shaping effect of the cone crusher is slightly better in general.

6. Price comparison

The cone crusher price is much more expensive than that of the fine jaw crusher.

7. Use and maintenance

We know that no matter which kind of crushing equipment, it is inevitable to do regular inspections and maintenance. Despite the high initial investment cost of the cone crusher, a low failure rate in the later stage, the long replacement cycle of wearing parts, and the convenient maintenance and repair, which saves a lot of manpower and material investment.

We know that it is uncertain to choose which equipment to use for medium and fine crushing through the comparison of the above characteristics. We should consider it comprehensively when purchasing. Considering the equipment cost, when both equipment can meet the crushing needs and the required quantity is the same, we generally choose the fine jaw crusher; For large-scale factory production operations, it should apply the cone crusher; When crushing wet and sticky ores, it should apply the fine jaw crusher; When processing flake or long-strip hard ores, it should apply the cone crusher is suitable. The specific equipment selection still depends on the user's production requirements.

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.

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.
