Dump Hopper

Product Overview

The Bag Dump Hopper provides a quick, easy and virtually dust free way of dumping and filling your process system with material received in paper bags. The design incorporates a baffle and bin vent (to attach to a central dust collector) or optional bin vent filter over the dump area to maintain a dust free worker environment while providing a fast and effective means to charge your process.


Ruggedly built for continuous, long lasting operation.

Hinged door to keep foreign materials from falling into the process material when not in use.
Expanded metal grid to prevent bag pieces from getting into the system.
Dump hopper exit cone that is easily transitioned to accommodate other Metalfab upstream or downstream equipment, such as a feeder, flexible screw conveyor, rotary valve for pneumatic conveying systems and so forth.
