Crushing is often the first step in the processing of solid minerals. Generally, the maximum particle size of the material is broken. In industrial production, the smallest product particle size that can be achieved by the crushing process is generally greater.

1 The main purpose of the crushing process is:

1) Prepare raw materials for the next mineral processing;

2) to facilitate the transport or storage of solid minerals;

3) Provide products such as artificial sand, building stones, etc.;

2 Segmentation of various crushing processes Due to different types, structures and rules of various crushing equipments, it is impossible to complete the whole process of solid mineral particle size reduction by a certain type of single-stage crushing equipment. Therefore, the crusher must be reasonably selected. Type, structure and specifications, and the reasonable distribution of the crushing ratio of each segment of the crusher. Crushing operations are usually carried out as follows:

1) Crushed (first broken). Open-pit mines generally have a feed particle size of 2000 to 1000, which is approximately 300 or so. Underground mines generally have a feed size of 600 to 350, and approximately 250 to 125.

2) Broken (second broken). Feed size 400 to 125. About 100 to 25 broken.

3) Finely chopped (third segment broken). Feed size 100 ~ 25. About 25 to 5 broken.

4) Ultra-fine broken (fourth broken). Feed size 50 to 25. About 60% is broken to about -6.

3 Crushing mechanism The crushing equipment introduced here are all broken by the application of mechanical force to ore rock, such as crushing, splitting, breaking or bending, grinding (applying shear stress), crushing and impact crushing. In general, the rock compressive strength is greater than the tensile strength, flexural strength and shear strength. Crushing machinery is often based on one method, broken by another or two methods.

Crusher series include: jaw crusher, impact crusher, PCZ two-in-one single-stage heavy hammer crusher, DPC three-in-one single-stage crusher, PXJ third-generation sand machine, PCH hammer crusher, PC More than 30 types of crushers, such as hammer crushers, adapt to various types of building materials, metallurgy, construction, beneficiation, coal, refractories, and other industries. The output of various sizes of stones and sand is to build ordinary Highways, highways, ordinary railways, high-speed railways, airports, urban large-scale interchange bridges, bridge piers, submarine tunnels, land tunnels, and the preferred products for concrete in urban subway projects.
