Factors affecting the quality of finished products in bluestone crushing production line

Various crusher equipment, such as jaw crusher, impact crusher, cone crusher, etc., are often used in many industries such as sandstone, construction, and coal mining. The quality of the finished materials produced by the crusher will directly affect the economic benefits of the overall crushing production. So for bluestone materials, what are the factors affecting the quality of the finished products of the crushing production line? What are the corresponding improvement measures? This article introduces you in detail.

The bluestone crushing production line mainly produces coarse stone materials of various specifications, and does not involve the sand making link. Therefore, the key equipment of the entire crushing production line is the crusher, which also makes the factors affecting the quality of the finished products of the bluestone crushing production line mostly concentrated on the crusher equipment. The following is a specific introduction to 3 influencing factors and corresponding countermeasures.

1. Crushing ratio

Impact: The crushing ratio refers to the ratio of the feed particle size to the particle size of the finished material after crushing, referred to as the crushing ratio. The larger the crushing ratio of the crusher, the corresponding needle-like content will increase, and this is true for all types of crushers; but if the crushing ratio is too small, the output of the entire bluestone crushing production line will decrease, the internal circulation volume will increase, thereby increasing the wear of the crusher and reducing the overall economic benefits.

Measures: In the entire bluestone crushing production process, it is very important to choose a suitable crushing ratio. Usually, the first crushing equipment is a jaw crusher with a large crushing ratio, and the secondary crushing equipment is an impact crusher or cone crusher with a relatively small crushing ratio.

2. Feed particle size

Impact: The feed particle size of bluestone raw materials will have a great impact on the particle shape of the output material. Relevant experiments have shown that when the feed particle size is reduced from 100mm to 50mm, the needle-like content in the finished material will decrease by about 38%.

Measures: A mature bluestone crushing production line should adopt a multi-stage crushing joint operation method, and divide the entire crushing process into three steps: coarse crushing, medium crushing, and fine crushing, to ensure that the coarse crushing reduces the bluestone particle size to below 400mm, and the medium and fine crushing of bluestone is crushed into the required 12 or 13 stone and other finished aggregates.

3. Crushing process

Impact: The first screening and then crushing crushing process is to first screen and grade the bluestone materials after the first crushing through the vibrating screen, and then send them to the secondary crusher for medium and fine crushing. This will increase the output of the finished material, but at the same time, it will also increase the needle-like content of the finished bluestone materials.

Measures: Change the process of first screening and then crushing to first crushing and then screening, and send all the bluestone materials after the first crushing into the secondary crusher. After repeated crushing, the bluestone finished products are uniformly screened and graded, forming a closed process flow as a whole, which will not cause the loss of broken materials. Although the circulation load is large, the particle shape of the finished material is very good.

In summary, in production, choose reasonable crushing equipment and crushing production line, and properly control the feed particle size, the bluestone crushing production line can produce finished sand and gravel products with good finished particle shape. Shibang Group can carefully design the bluestone crushing production line according to customer needs and recommend suitable crushing equipment. At the same time, it has always focused on the production of mining machinery, the equipment quality is guaranteed, the manufacturer sells directly, and also gives extra accessories, which is worth cooperating.
