What equipment is used to process the stones on the railway ballast?

Ballast raw materials cannot be directly put into use after being mined. They need to be processed by appropriate processing equipment, and can be used as ballast after they meet specific requirements in terms of needle index, flake index, weathered particles, and surface cleanliness. use.
The production of ballast generally uses jaw crusher, cone crusher, and some auxiliary equipment. The processing process is roughly as follows: raw material → jaw crusher → cone crusher → vibrating screen → belt conveyor → ballast .

1. Jaw Crusher

The jaw crusher is specially used for the coarse crushing of large pieces of ballast raw materials (≤1200mm), the crushing ratio is large, and the discharge is between 10-350mm, which is helpful for the second-stage crushing treatment of the stone; "V" type crushing The cavity design is deep and has no dead zone, so there is no need to worry about the problem of material blocking in the equipment; the wedge is used to adjust the discharge opening, which not only reduces the work intensity, but also reduces the downtime.

2. Cone Crusher

The material discharged from the jaw crusher can meet the feeding requirements of the cone crusher, and then it can enter the cone crusher for the second-stage crushing treatment. It depends on the selection of the equipment model, as well as the actual operation conditions such as the size and nature of the feed.

The cone crusher adopts the principle of lamination crushing. Even in the face of high hardness stone, there is no need to worry about speeding up the wearing speed of wearing parts, which effectively solves the problem of high operating costs in the later stage.
