Screw conveyors for grain processing and feed mills
Optimize your production line with versatile screw conveyors, designed to efficiently handle and transport bulk solids like grains and powders, ensuring seamless integration and precise material flow.

Conveys and Feeds Solid and Granular Materials
Ottevanger Milling Engineers offers a range of screw conveyors designed for effective material handling across various industries, including grain processing, aqua feed, and food production. These conveyors efficiently move solids and granules using robust, S235 steel troughs, available in tubular or U-shaped designs, to ensure durability and long service life. With features like geared drive units and intermediate bearings, they provide reliable operation while preventing shaft sagging.
The screw conveyors support applications from dosing to conveying, integrating seamlessly into automated production lines. You’ll benefit from options such as ATEX22 zoned drive-units and variable pitch screw blades for enhanced safety and control. Their flexibility allows handling of materials like flour, fish pellets, and chemical powders, with the added advantage of corrosion-resistant AISI304 or galvanized S235 steel construction for specific application needs. Reduce energy consumption with frequency-controlled drive-units, and maintain operational hygiene and ease with intermediate outlets for efficient discharge. Tailored engineering support and configurations ensure these conveyors meet your specific production demands.
