Forgócsavaros

Forgócsavaros refers to a type of screw conveyor, a mechanical handling device used for the transportation of bulk materials. In its simplest form, it consists of a helical screw rotating inside a stationary tube or trough. As the screw rotates, it pushes the material along the tube.

These conveyors are widely employed in various industries, including agriculture, food processing, chemical manufacturing, and mining. They are suitable for conveying a range of materials, from powders and granules to semi-liquids and sludges, provided the material has sufficient flowability. The design of the screw, casing, and drive mechanism is adapted to the specific properties of the material being handled and the required throughput.

Forgócsavaros conveyors offer several advantages. They are relatively simple in construction, require minimal maintenance, and can be operated in a dust-tight or liquid-tight manner, which is beneficial for handling hazardous or sensitive materials. They can also be configured to handle materials at different angles, including inclined and vertical transport. However, they are not ideal for conveying fragile materials as the screw action can cause breakage. Wear and tear can also be a concern depending on the abrasive nature of the conveyed substance. The term itself is of Hungarian origin, combining "forgó" (rotating) and "csavar" (screw).
