Mobile Double Roller Crusher

The roller crusher performs crushing operations through rollers. The material enters between the rollers through the feeding port and crushes the river pebbles through compression. There is a gap between the two rollers, and the gap between the two rollers increases, resulting in a larger particle size of the material.
