How can I take in product from a bulk truck?

Bulk transport can be delivered in various forms. This form determines how the product must be accepted.

Raw materials such as maize and grains are often dumped from trucks. Landfilling is generally done by means of gravity. The low product speed has the advantage that there is little wear on the equipment. Corn and cereal trucks can be back-unloading or under-unloading. With a rear unloading truck, the tank is tilted upwards and pressurized. At the point where the product leaves the tank, additional transport air is added to fluidize the product. This lowers the flow resistance resulting in smooth emptying. In the case of a bottom unloading truck, the truck parks above a grid in the floor. The raw materials then fall through this grid into a hopper, after which they are transported with a redler (horizontal chain conveyor) or with a screw to an elevator (vertical belt conveyor with cups).

Powders are often brought into the factory by pneumatic transport. Bulk trucks with a tank are designed to connect their product flow to the pipeline network of the unloading site by means of pneumatic transport. The truck is equipped with its own compressed air supply. In this way, the truck combination can unload independently at any location. The condition is that the storage system at the customer is prepared for this. For example, the silo or bunker must be equipped with a filter separator. This filter ensures that the transported product remains in the silo and that the transport air can escape from the system. This filter must be cleaned during the transport process with compressed air or cleaning pulses.

Powder can also come in in a bulk container with a plastic liner. The advantage of a plastic inliner is that there is no contact between the product and the steel container. A possible disadvantage is that a container with inliner cannot be pressurized. If a plastic inliner is used for pneumatic transport (blow or suction transport), this can only be done by means of a sluice. This lock also functions as a dosing system to allow the flow to be controlled. In this system, the compressed air supply is usually stationary for transport. The container with liner can also remain in stock for a longer period of time. The trailer with container then acts as an exchange system.
