Industrial roller mill for grain size reduction
Achieve precise grain size reduction with minimal heat generation and optimal energy efficiency. Perfect for continuous, high-capacity operations that demand adjustable control over the milling process.

Processes and Compresses Granules with Precision
The roller mill from Dinnissen is engineered for efficient granule and powder processing across diverse industries including food, pharmaceuticals, and chemicals. It employs two counter-rotating rollers to compress and shear materials, minimizing fines content and ensuring a uniform grain size. This machine is capable of processing cereals, oilseeds, biomass, and minerals, producing end-products such as cornflakes, soybean meal, and vitamin premixes. Designed for continuous operations, it offers adjustable roller spacing for precise size reduction and supports high-capacity output with minimal heat generation, preserving product integrity.
With in-house production and rigorous quality control, Dinnissen ensures robust construction and long service life. The roller mill integrates easily into existing production lines and is PLC-controlled, allowing seamless automation and remote monitoring. Energy-efficient, it incorporates low heat emission technology and variable speed controls, reducing energy consumption. Available with customizable roller profiles and spacing options, this mill meets stringent industry standards with configurations tailored to specific material and process requirements. Advanced cleaning systems facilitate quick maintenance and compliance with hygiene standards.
