ROCK BULLS MACHINERY

PYFB  Series Spring Cone Crushers, which have been researched and developed by ROCK BULLS,  a Chinese-based manufacturer of crushers, adopt the principles of lamination crushing along with the concept of crushing more and grinding less. Our PYFB Series Cone Crushers integrate high swing frequency, optimized cavity type, and rational stroke. Their excellent performance and reliability under many different working conditions make them very popular with our customers.

They utilize a spring safety device, a large diameter main shaft, a heavy rack, and a dry oil seal which greatly increase reliability. There are two models of our high-efficiency PYS Series Spring Cone Crusher: a standard model and a short head model. Both models are equipped with multiple cavities thus ensuring that they are suitable for both fine and intermediate crushing of various materials with different hardness. Spring Cone Crushers give outstanding performance in a large number of applications when being used in intermediate crushing situations.
