Bulk Bag Unloaders

Product Overview

Metalfab Bulk Bag Unloaders are designed and engineered to provide a dependable, low cost means for emptying a wide variety of powders and other difficult to handle dry bulk materials. Metalfab also manufactures other special units for heavier bags, larger bags, or smaller bags.

To assure discharge of product, the ruggedly built 48" sq. pyramidal shaped Unloader is mounted on wear-resistant rubber isolators that eliminate any transmission of vibration to the support stand or surroundings. Solidly mounted to the Bulk Bag Unloader is a time-tested, field-proven, Metalfab Vibrator. This Vibrator can be adjusted to provide varying levels of vibration, as needed, to discharge product from the bag. All of our Unloader Vibrators are ruggedly built to withstand the rigors of vibration and all are totally enclosed, non-ventilated and are also available in an explosion proof enclosure.

While voltage can vary by request, all vibrators are three (3) phase. They provide years of maintenance-free operation and come with a Metalfab guarantee for 30 months.

Metalfab bulk bag unloaders are not only dependable but versatile as well. They are available as a standard model with support and bag rack, a hoist rack model with hoist hook and for stationary posts to hold bag straps with volumetric screw or belt feeders, liner retractors, special closure gates and many other options.
