The chain conveyor moves in a continuous circuit the material at high speed. The flexibility of the chain enables it to be installed in almost any configuration. The chain is pulled through the circuit by a drive unit. The material is introduced into the system by means of a hopper with a vibrating wall that helps keep the material flowing. The material can be discharged from the circuit at any desired location by holes placed in the bottom of the tube. Any style of drop can be installed on the tube under the hole.
