VERTICAL SCREW CONVEYORS

The Orthman vertical screw conveyor system is a great solution to many material handling problems by providing a cost effective elevating action with minimum space requirements. The vertical is fed by a horizontal feed screw which is synchronized with by speed and feed rate. Both the feed screw and the vertical are driven by independent screw conveyor drives. We offer this system in multiple materials of construction including carbon, abrasion resistant, stainless or any combination.
Although we have standards the length of the feed screw, the height of the vertical as well as the diameter of each can be designed to each specific application.

The Optimal Solution for Elevating Materials

The Orthman Vertical Screw Conveyor system is a premier solution for diverse material handling needs, offering efficient vertical elevation of materials in a space and cost-optimized design. Essential for transporting dry to semi-dry bulk materials, it is particularly adept for handling wood products and free-flowing substances. The system combines a horizontal feed screw and a vertical screw, synchronized for maximum efficiency in speed and feed rate, each powered by independent drive units for precise control.

Available in various materials like carbon, abrasion-resistant constructions, and stainless steel, it can be customized in terms of the length of the feed screw, the height of the vertical conveyor, and diameter, providing a versatile solution tailored to individual application requirements.
