What's a Double-Roller Crusher?
The double-roller crusher should strengthen the iron removal work of feeding ore. Non-crushing objects (bits, etc.) falling into the pair of rollers will damage the crusher, resulting in a parking accident. Therefore, an iron removal device should be installed before the crusher. The viscous material is easy to block the crushing space.
