ABSTRACT:
A hopper assembly is combined with a two-roll crusher unit to form a combination which not only mixes the product with the fluid but also crushes the product slurry prior to its entry into the pump. The combination essentially comprises a hopper formed by constructing an open-top tank having horizontal dimensions which are greater than the vertical dimensions and having interconnected walls and sidewalls and a bottom tapered downwardly toward one end wall. Water is fed into the tank adjacent the higher end of the bottom. The granular solids are fed into the tank from the top adjacent the higher end of the bottom. A plurality of partitions is placed across the tank extending down into the water to limit the flow of water in the upper portion of the tank, thereby minimizing wave action. Water level sensors are also mounted in the tank to maintain the water at a predetermined level in the tank. The crusher unit consists of two rolls, each having a plurality of spaced peripheral teeth. The rolls are journaled across the opening which is formed in the lower end of the tank. The rolls are journaled and motor driven so that material flowing between the rolls will be moved in the direction of the outlet.
