Finally, an ultra fine powder of 60-110 mesh comes out the bottom of the roller mill.   As a result, a single pass, through this crusher, will reduce rock to an ultra fine powder that would take two passes or more in the two stage single roller model.  As a result this saves production lime.

High rock crushing capacity

Model RC-46 Rock Crusher is an amazing 3 Stage Compact Rock Crusher. Due to three stages, this model quickly crushes 4″ x 6″ Rock into ultra fine powder.  First the RC-46 quickly crushes rock into 1/8 inch in size through the first stage jaw crusher. Then, the output of the jaw crusher automatically feeds into the roller mill which reduces the material into fine powder. Material is then passes through the roller scraper.  This further reduces the material into “Ultra Fine Powder”.  Finally, oversize material may require an additional pass.
