What are the conditions required for a granite crusher?

Granite crusher should be able to quickly crush large pieces of granite into smaller particles with a large crushing ratio, thereby improving production efficiency and material utilization. It should be able to process granite raw materials of different particle sizes and reduce pretreatment costs. Crushing parts such as jaw plates, hammerheads, and impact plates are made of high-strength, high-wear-resistant materials, which can resist the wear of hard materials such as granite and extend the service life of the equipment.

Granite has a dense structure and extremely high compressive strength. The compressive strength of rock blocks can reach 117.7 to 196.1 MPa, and even the compressive strength of fine-grained granite can exceed 300 MPa. This high compressive strength makes granite an ideal material for building large-scale projects such as hydropower station dams and bridge piers.

Crushing process and equipment

According to the requirements of the finished product, a complete crushing line includes coarse crushing, medium crushing, fine crushing, and grinding.

Jaw crusher always used in the first crushing section, can crush large-size material with less than 350MPa of compressive strength to a size of 100 mm to 300 mm.

Impact crusher generally takes effect at the second crushing section, and can process the <500mm rock ore which with compressive strength up to 350MPa, output cubic grain.

Cone crusher/ conical crusher same as the impact crusher can be put in the second crush processing sector, with feed size 13~369mm is less than the impact crusher’s. cone crusher is a high-efficiency crusher machine which with high crushing efficiency, and less replacement.

Sand-making machines usually in the last crushing process, and feed size is 35~60mm, the sand maker is suiting for is suitable for the crushing and shaping of soft, medium-hard, and extremely hard materials. Generally, it is the last process of the crushing sand production line, and the feeding granularity is 35~60mm.

In addition to the main crushing equipment, some auxiliary equipment such as vibrating screens, material feeders, and conveyor belts are required to cooperate with the crusher machines.
