The movement and storage of products in bulk such as powders or granule, is made prevalently using sacks or bulk bags. In processing plants that use raw materials in bulk we can find different bulk bag handling systems, connected to conveyors, mixers and filling machines.
Gimat bulk bag handling equipment have been developed to meet the needs of different types of industries and include food grade equipment for hygienic production processes in the food and chemical industry.
Bag dump stations
In the bag emptying machines, with or without a cover, the operator manually pours the contents of the sack into the hopper. The safety of this operation is ensured, from the standpoint of the chemical risk of exposure to the powders, by fitting the powder containing hopper with a suction hood for connection to the customer’s exhaust system. On request, suction hoods can be equipped with a particle filtration system and centrifugal fan for the extraction of the powders and an air jet kit for cleaning the filtration sleeves with cross-current compressed air.
Bulk bag unloaders
In a big bag unloading system, the bulk bags containing the product are conveyed to the supporting frame via lift truck, ready for easy hoisting.
The operator can then open the discharge mouth of the bulk bag safely and without scattering powder in the environment. Different types of powder seals can be used depending on the type of product contained in the bulk bag.
The bulk bag unloaders are height adjustable and easily adapt to the dimensions of the bulk bag. They are designed to be paired with powder conveyor systems such as: flexible spiral conveyors, screw conveyors or pneumatic conveyors.
The accessories engineered by Gimat (applicable to both bag dump stations and bulk bag dischargers) ensure regular pouring of the materials in the bags:
• Mechanical bridge breakers in various versions
• Lump breakers
• Bin activators
• Electromechanical vibrators
Bulk bag fillers
The bulk bag filling frame allows you to support the FIBCs during the filling phase safely and without dispersing dust in the environment.
The filled bulk bag is then easily detachable with the help of a forklift or a pallet truck for lifting the filled bag from the bottom and placing it on the pallet.
The telescopic structure of the bulk bag filling equipment allows you to make adjustments to the height in order to adapt to different sizes of FIBCs.
The filling process can be carried out by flexible spiral conveyors, screw conveyors or pneumatic conveying systems with the possibility of aspirating the dust generated, with a light vacuum.
The bulk bag fillers can be equipped with loading cells for dynamic weighing of the content.
As an alternative to a simple strap for fastening around the “neck” of the bulk bag or filling mouth, the bulk bag can be fitted with an inflatable sleeve that ensures a perfect particulate seal combined with the practicality of fastening directly to the filling pipe.
