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.

Before Starting the Jaw Crusher, it is Essential to Check These-Vanguard Machinery Tech

 Before starting the jaw crusher, the operator needs to do some inspections to ensure that all components are normal and there is no blocking material in the crushing cavity. In addition, pre-startup inspections can also help you discover faults in time, nip them in the bud, and avoid greater losses. So, what aspects need to be checked before starting the jaw crusher?

Lubrication condition

Before starting the jaw crusher, check whether the jaw crusher toggle plate is sufficiently lubricated, which is a prerequisite for ensuring the efficient operation of the crusher. The toggle plate is a component that transmits power to the movable jaw of the crusher. It plays the role of supporting the movable jaw plate in the jaw crusher and transmits the crushing force to the rear wall of the frame. If poor lubrication, it will directly affect the working efficiency of the jaw crusher.

Fasteners status

Check whether the various fasteners of the jaw crusher are loose. Once found, tighten them immediately to reduce the probability of jaw crusher shutdown accidents.

Conveyor belt condition

Check the integrity of the conveyor belt. If there is any damage, it should be replaced immediately. If there is oil pollution on the conveyor belt, wipe it clean with a rag.

Defensive equipment

Protective devices are an essential indicator to check because they are related to safety issues. Once problems are discovered, they should be solved in time to avoid accidents.

Check the crushing chamber

Check the oily ore or debris in the crushing cavity. Once ore or debris is found, the operator should clean it up and ensure that the jaw crusher cavity is activated.

After checking the above aspects, if there are no problems, you can start production. In addition, operators must pay attention to safety during production.

How to Improve the Crushing Effect of Multi-cylinder Hydraulic Cone Crusher by Controlling Power and Material Level?-Vanguard Machinery Tech

 The multi-cylinder cone crusher has the characteristics of large production capacity, high efficiency, laminated crushing, excellent final product particle shape, simple operation, and a high degree of automation. It is widely used in medium and fine crushing in the sand and gravel aggregate industry and mining industry, especially in medium-hard material processing systems. In the production of multi-cylinder hydraulic cone crushers, some on-site application methods can be used to effectively improve the crushing effect of the cone crusher.

Power Control

In the process of applying a multi-cylinder hydraulic cone crusher for on-site work, its main work control method is the change of feeding amount. Therefore, in the specific working process, if the feed volume is large, the driving power requirements of the mechanical equipment will also be large. To ensure its working quality, its working power should be controlled between 75% and 90%, and its maximum power should not exceed the rated power. At the same time, during on-site work, operators should strictly avoid running the crusher in a low-power state. If it is running, its running time should not exceed 5 seconds. In specific on-site crushing operations, the power of the crusher must reach more than 40% of the rated value.

Material level control

In field applications, if the multi-cylinder hydraulic cone crusher has been running for more than 30 minutes but still cannot feed, the crusher needs to be temporarily shut down and then turned on again when feeding is possible. When the cavity of the multi-cylinder hydraulic cone crusher is crowded with materials, its optimal working condition is when the operating power reaches 75% to 90% of the rated value. In specific operations, the work of the multi-cylinder hydraulic cone crusher needs to be controlled by changes in the feed volume, and the discharge port is used as an auxiliary control facility. The adjustment of the discharge port can effectively compensate for the wear of the liner. Ensure the stability of product particle size. At the same time, the tight edge discharge port adjustment and cavity type selection can also be used to ensure that the crusher cavity is filled with materials. Under normal circumstances, the height of the materials in the cavity should exceed the material distribution plate by more than 300mm. The driving power should be kept stable and controlled at 75% to 90% of the rated value.

During on-site operations, the radar level meter can be used to detect the material level in the crusher cavity, or it can be used as a device to control the signal input of the material quantity control loop in the crusher. When the material in the crusher cavity is crowded Finally, the driving power can be further optimized through reasonable adjustment of the discharge port. For example, after the crusher discharge opening is increased, the given material level driving power of the crusher will be reduced, meanwhile, the feeding amount in the crusher cavity will be increased; After the reducing crusher discharge opening, the given material level driving power of the crusher will be increased, meanwhile, the feeding amount in the crusher cavity will be reduced.

Multi-cylinder hydraulic cone crushers have exerted good application value in many fields today. Compared with traditional crushers, the installation of multi-cylinder hydraulic cone crushers is simpler and more convenient, and their work efficiency and work quality are also higher. In production, it is necessary to control the on-site application of multi-cylinder hydraulic cone crushers and perform targeted operations to improve the production efficiency and quality of the equipment.

As one of the flagship products of Vanguard Machinery, the CP series multi-cylinder hydraulic cone crusher has been widely used in production lines everywhere and has achieved good market response. This series of crushers has a good grain shape with laminated crushing, accurate and reliable full hydraulic control, and easy equipment maintenance.
