Screw conveyors

Laitex Screw Conveyors are designed for demanding processing conditions that are tailored specifically for the customers’ and plant’s needs. Screw Conveyors are commonly 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.
