Which crusher to choose when the rock hardness is high?

Rocks are substances that make up the earth's crust. They are solid aggregates with stable shapes. There are many types and different hardnesses. After crushing, they are used in the construction industry, glass manufacturing, cement, steelmaking and other fields. Which kind of crusher should be used when rocks are too hard? Is the machine good?

Rocks composed of one mineral are called monolithic rocks. For example, marble is composed of calcite, quartzite is composed of quartz, such as granite is composed of quartz, etc. Currently, there are many types of rock crusher equipment, and for processing hard rock, It is more suitable to choose wear-resistant equipment such as jaw crusher and cone crusher, which solves the problem of high operating costs in the later period and is easy to use and affordable.

1. Jaw crusher

Jaw crusher is often used for primary crushing. It adopts the working principle of extrusion crushing and is suitable for materials with a compressive strength of 320 MPa. Its crushing cavity is deep and has no dead zone. It uses large bearings and forged spindles to carry greater crushing force. , coupled with the flywheel design, reduces vibration and runs more smoothly, and also carries out hydraulic design, with reliable performance, low failure rate, adjustment of the discharge port gasket, and complete finished product specifications.

2. Cone crusher

Cone crushers are often used in medium crushing operations. They adopt the principle of laminated crushing. The rolling mortar wall moves toward the crushing wall to squeeze the material. The discharge port is adjusted by a hydraulic motor. The adjustment and operation are easy. The finished product has many needles and flakes and poor particle shape. It needs Equipped with a shaping machine, the price is slightly more expensive, but the wearing parts have a long service life.

cone crusher

For rock crusher equipment, the price ranges from high to low, mainly related to the equipment type, model and manufacturer selected by the customer. It is recommended that everyone first understand their own needs, such as production capacity requirements, material properties, specification requirements, budget, etc. Only in this way can the manufacturer recommend a suitable model and quote for you.
