Abstract: Apparatus for melting and dispensing very high viscosity material, such as butyl. A chamber with heated walls is provided with an internal conveyor and pump near the bottom wall of the chamber. The conveyor has sections which transfer rotational energy to material within the chamber, dragging high viscosity material to a pump inlet hole in the bottom wall of the chamber. Deflection plates mounted within the chamber push material down onto the conveyor, so that pump suction can be maintained. The plates also promote vertical as well as horizontal material mixing, thereby exposing new surfaces of the thermoplastic material to the heated walls of the chamber, increasing the rate of heat transfer from the walls to the material.
