Project Description

Screw conveyors with Hopper – The screw conveyor hopper from Watcco Engineering is specially designed to increase the flow of both free-flowing and non-free-flowing bulk materials. The ultra-modern high flow hopper with flexible screw conveyors is deliberately engineered to eliminate or decrease the amount of residual material in the hopper as well as the need for flow promotion devices. The hopper walls direct the material into a rotating flexible screw more positively than with previous rectangular interface adapters. This is one of the biggest advantages and prime reason for the critical recognition of the product. The screw conveyor with hopper is an efficient material handling system and one of the most durable machines under the segment.
