Abstract
An apparatus for crushing solids in a liquid medium includes one or more pairs of cylindrical members rotatably journaled in the sidewalls of the liquid-filled vessel. The cylindrical members have crushing elements which are integrally provided on the surface of the cylindrical members. The material to be crushed is mixed with the solution in the liquid medium contained within the vessel and pumped out of the bottom of the vessel into a slurry line.
Claims6
In a slurry hopper having sidewalls, first and second endwalls, and a bottom wherein said bottom slopes from said first endwall to said second endwall, a water inlet means at said first endwall for partially filling said slurry hopper with water, an outlet in said second endwall, an improvement comprising a product sizing unit having a plurality of cylindrical rolls journaled substantially parallel with the surface of the water in said slurry hopper, said cylindrical rolls including a plurality of spaced peripheral teeth along the length of said cylindrical rolls, means for counter-rotating adjacent rolls of said plurality of cylindrical rolls, and means for maintaining the level of said water in said slurry hopper between the upper surface and the lower surface of said plurality of cylindrical rolls.
