Bulk bag fillers

The bag can be attached to a frame that has forklift blade slots included for easy manipulation of the bag once full. To aid with bag filling it is also possible to have load cells 

As with all of the equipment we have discussed so far, these are all available in a wide range of materials. While the frames are generally constructed from a mild steel, as they do not come into contact with the process material, a wider range of materials are available for the loading chute. These can range from high quality stainless steels for food and pharmaceutical applications to lower grade mild steels for less arduous duties. The static frame noted above can be used in applications where frequent wash downs are required for sanitary purposes. 

For operations that use a variety of storage containers there are designs that are adaptable to this application. This is achieved by fitting an adapter to the filling chute used to fill the IBCs. Another option that is available for all of the configurations mentioned above is the pre-inflation of the bag prior to filling. This allows the material to flow freely into the bag without any physical obstructions. However, it is important that the material be de-aerated 

As with the bulk bag dischargers, the materials used in, and the application of, bulk bag fillers is wide and varied. However, the same proviso holds care must be taken to ensure that the system is adequately designed to take into account the flowability characteristics of the material. Some example materials and applications are the loading of polymer resins into a variety of container sizes the batch weighing of PET the filling of bags in a carousel

Fillers in the form of an aqueous slurry are stored in concrete or steel tanks. Care must be taken that the slurry temperature does not drop below 10°C. Handling problems develop when the slurry temperature is below 5°C. Overheating (above 35°C) should also be prevented. Materials packed in unitary packages should be stored in conditions specified by the producer. Bags are usually stored in a palletised form, whereas intermediate bulk containers are stacked three high, possibly on pallets or suspended on special metal pallets by means of loops. 

The technologies, equipment, and plants described above are mostly used for single or multi-component fertilizers and for fillers (such as limestone) and mixtures of inert carriers loaded with small amounts of micro nutrients. After screening-out a granular particle distribution (typical size about 1-6 mm), this product is either directly suitable for bulk shipment or bagging and use or, as discussed before, it is a component for bulk blending. As mentioned earlier, it is also possible to produce pillow- or almond-shaped briquettes (about 20 cm ) as urea supergranules for deep placement in wetland...
