The Spring Cone Crusher is widely used for secondary and fine crushing in the fields of mining, chemical industry, building materials, metallurgies and so on. The Cone Crusher can crush materials with Moh’s scale in middle and high hardness such as ironstone, copper ore, limestone, quartz, granite, rock and so on. The standard type (PYB) is applied to secondary crushing; the medium type (PYZ) and the short-head (PYD) are applied to fine crushing. Working Principle Of Cone Crusher:   When the cone crusher is working, the motor drives the eccentric bearing bushing via spring coupling, transmission shaft and a couple of cone gear wheel. The crushing cone axis is forced to swing by the eccentric bearing bushing, which makes the mantle sometimes close to the bowl liner, and some times far away from the bowl liner. The raw materials are pressed, impacted and finally crushed in the crushing chamber.   Features Of JOYAL Cone Crusher:   1. Big capacity and good quality; 2.
