White screw conveyor and an engineer.

Screw conveyors

Screw Conveyors are used to convey semi-solid bulk materials over short distances. The material flow can be flexibly controlled either horizontally or vertically. Commonly, they are used for conveying, discharging, and feeding bulk materials such as wood chips, sand, and ash, but are also applicable to wet material. 

Laitex Screw Conveyors are designed for heavy duty industrial use. They are cost-efficient solution for conveying bulk materials over short distances both horizontally and vertically. Equipment is tailored based on, capacity, distance, bulk material and intended use. Our easy-to-apply conveyors can also be customized to cool, heat, and divide the material flow. Our Screw Conveyors are designed for demanding processing conditions that are tailored specifically for the customers’ and plant’s needs.
