Application of gyratory crusher in large-scale machine-made sand and gravel production line

The coarse crushing process is one of the key links that affect the technological upgrading of machine-made sand and gravel production enterprises. The use of gyratory crusher instead of jaw crusher in large-scale machine-made sand and gravel plants can effectively improve the technical level of mining and coarse crushing process, improve the production efficiency of medium and fine crushing, and reduce the overall production cost; and the development and application of gyratory crushers at home and abroad are relatively mature. Therefore, it is technically and economically feasible, which is of * significance to improving the * competitiveness of enterprises and is the development direction of large-scale sand and gravel processing enterprises in my country.

1. The gyratory crusher has a large crushing ratio, a larger feed particle size than the jaw crusher, and a smaller discharge particle size.

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

3. The gyratory crusher adopts the principle of inter-material lamination crushing, and the service life of the wear-resistant parts of the jaw crusher is long, 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 conducive to extending the service life of the wear-resistant parts of the cone crusher.
