Coarse crushing process is one of the key links affecting the technical upgrading of machine-made sand and gravel production enterprises. Large-scale machine-made sand and gravel plants use gyratory crushers instead of jaw crushers, which can effectively improve the technical level of mining and coarse crushing, and improve the production efficiency of medium and fine crushing. Reduce * production costs; and the development and application of gyratory crushers at home and abroad are relatively mature. Therefore, it is technically and economically feasible, and it is of * significance to enhance the * competitiveness of enterprises. It is the development of large-scale sand and gravel processing enterprises in my country. direction.



1. The crushing ratio of the gyratory crusher is large, and the particle size of the feed material is larger than that of the jaw crusher, while the particle size of the discharge material is smaller.

2. The production capacity of a single gyratory crusher is *er than that of a jaw crusher, and the average energy consumption of a medium-sized gyratory crusher is much lower than that of a large and medium-sized jaw crusher.

3. The gyratory crusher adopts the principle of laminated crushing between materials, which has a long service life than the wear-resistant parts of the jaw crusher, and the content of needle-like particles in the discharge is generally less than 10%. Optimizing the particle shape of the coarse crushing discharge is beneficial to prolong the service life of the wear parts of the cone crusher.
