Ottevanger has designed screw conveyors for the horizontal and slightly inclined transport of bulk goods with a maximum particle diameter of +/- 15 mm.
The transport capacity and the variety of products that can be moved with a screw conveyor are exceptionally high. Screw conveyors are used in:
- the grain processing industry,
- animal-feed plants,
- mixed-feed installations as a dosing tool,
- the chemical industry,
- the food industry.
Screw conveyors are also used as discharge equipment.
The shaft with the propeller blades rotates in a tubular or U-shaped trough. The propeller blade moves the product from the intake in the trough to the outlet on the drive side. The product does not rotate but moves forward. Intermediary outlets can be provided between the intake and the final outlet. The screw shaft is supported at set intervals by intermediate bearings. The drive group consists of a motor reducer, directly connected or fitted with a chain gear.
