General
The use of Bulk Bags (or Big Bags / FIBC's as they are often referred to) has exploded in recent years as more and more companies with bulk material handling needs have sought to take advantage of the savings they can potentially offer.
We manufacture a number of Bulk Bag Discharger configurations, with a wide range of options for efficient Big Bag emptying using an integral conveying or elevating system - ideal for charging storage silos, feeding filling machines, mixers, dosers, reactors and for use in many other processing and bulk solids handling applications.
Guttridge Bulk Bag Discharge Systems are built around our unique Multiflo rigid screw conveyors and Easyflo rigid screw elevators, providing the ultimate in rugged, durable design with an almost zero cost spares requirement, as well as genuine easy cleandown facilities. Our steeply inclined screw elevator options also result in a small footprint - ideal for confined spaces.
Specification
The Bulk Bag Discharger can work as a stand-alone piece of equipment, or can be combined with one of our discharge applications. The most popular are the Sieveflo, Multiflo and Easyflo, but the Bulk Bag can also be combined with a Flexible Screw Conveyor and Bulkflo dependent upon customer requirements.
Bulk Bag Discharger with Multiflo
This model is based around our Multiflo tubular screw conveyor system and is available in a number of configurations - extended hopper, multiple screw, horizontal discharge, agitators etc, depending on the particular material characteristics and site requirements.
Bulk Bag Discharger with Easyflo and Sieveflo
This model is based around our Easyflo and Sieveflo screw elevators, it provides the ultimate in flexibility as the Easyflo/Sieveflo hopper loader can be used separately for discharging 25kg bags, boxes or drums. The Sieveflo option provides a useful integral check sieve to catch foreign objects before they enter the main system. A number of configurations are available, depending on the particular material characteristics and site requirements.
Bulk Bag Discharger with Flexible Screw Conveyor
This model is based around our range of Flexible screw conveyor systems and is available in a number of configurations - extended hopper, and agitators etc, depending on the particular material characteristics and site requirements.
