How do you fill a container liner with dry bulk goods? With a screw system especially designed for container liners, of course! This horizontal screw with its open base is placed in the opening of the liner. The construction is such that the product cannot leak. Within half an hour, your 20ft container will be over 80 percent full.
With a screw conveyor, dry bulk goods are easy to load into a container. Even if the container is equipped with a liner, a large bag that lines the walls of the container. We have designed the container liner filler especially for this purpose.
The liner filler is a horizontally mounted screw conveyor which allows 20ft containers to be filled with granulates (plastic granules), powders (such as flour) and flakes. The screw is fed from an inlet hopper mounted either above or via an opening. The hopper can be filled from a silo, a Dino bulk truck loader, with bags or a with shovel.
The frame on which the filling screw is supported is available with optional wheels. The liner filler can then be moved by a forklift truck and used in other locations.
A truck with a 20ft container reverses and slides the open tail of the container over the screw. As soon as the screw is fully inserted into the container, loading can begin. This operation can also be carried out in poor visibility, thanks to the powerful work lights which can be controlled from the switch box. Through the open base of the screw, the load first falls to the rear of the container, where it forms a mound. As soon as it reaches the height of the auger, the load then automatically falls further forward towards the front of the container. The end of the screw is equipped with a full-flow detection system. This ensures the screw stops automatically when the container is full. A chute around the screw prevents spillage of the product.
A common method for moving powders and granules is by blowing air. This method is comparatively energy-consuming. Conveyor belts often cause loss of product and disruptive air movement, which is why screws have become an attractive option. Being mechanically driven, they are usually more cost-effective than pneumatic air. In contrast to conveyor belts, the entire construction is built to eliminate product loss. A clean and safe working environment is therefore guaranteed.
