Screw conveyors are used for the transfer of mixed raw materials and products and are usually mounted downstream of another distribution unit (extraction screw, mat, rotary valve…)
Screw conveyors are also used to extract products or raw materials from storage silos or hoppers.
Screws are also used for dosing in order to increase the accuracy of the dosing operation and enhance the regularity of product flow.
Assets of screw conveyors:
- Highly flexible
- Suited to most powdery products
