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.

Fundamentals of roll crusher grinding. In a roll crusher, material is fed from the top into a narrow gap (called the nip) between rotating cylindrical rolls, which grind the material to the desired particle size. Roll crushers can be configured with one, two or three pairs of rolls, depending on the application.
