Abstract: Apparatus for forming a particulated solids-carrier liquid slurry and transporting it between first and second locations wherein a continuous stream of carrier liquid is flowed to the first location at a constant flow rate and particulated solids to be transported are injected directly into the carrier liquid so that a particulated solids-carrier liquid slurry is formed. The slurry is pumped to the second location at a flow rate such that the pressure level of the carrier liquid at the first location is maintained at a predetermined level thereby facilitating the direct injection of particulated solids thereinto.

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.
