Cryloc rotary screens for grain processing
Efficiently sort and separate fine particles with high precision to enhance product quality in high-speed, continuous processing environments.

Separates and Screens Raw Materials Efficiently
The Cryloc Rotary Screens from Ottevanger Milling Engineers provide a robust solution for efficient particle separation and screening in grain and feed processing. Housed in a cylindrical structure, these rotary screens are equipped with one or two specially formed screens to separate fine particles effectively. Ideal for processing raw materials, pellets, and crumbs, the Cryloc Rotary Screens ensure less than 1% fines in the final product. With a capacity range from 20 to 180 tons per hour and optional single or double screen decks, these screens adapt seamlessly to various production requirements. The electro-pneumatic operated valve between the screens and position feedback sensors allow precise control over processing. Built for continuous and high-speed operations, these screens are certified for ATEX zone 21/22, ensuring safety in explosive environments. The automatic cleaning feature with compressed air maintains performance by preventing blockages, and Ottevanger offers customization options to meet specific production needs.
