Roller Mill

The Roller Mill is the core grinding machine of modern flour and semolina mills, designed to progressively reduce grain into flour, semolina, and intermediate products through a controlled grinding process.

GENERAL DESCRIPTION

The Roller Mill is the heart of every modern milling plant and plays the most critical role in transforming wheat, corn, and other grains into high-quality finished products. Through a carefully controlled grinding process, it progressively reduces the grain while preserving product quality and maximizing extraction efficiency.

The machine utilizes precision-engineered rolls rotating at different speeds to create a shearing and compressive action on the product. This differential roll speed allows the grain structure to be opened gradually, enabling efficient separation of endosperm from bran while maintaining optimum particle size distribution.

In flour milling applications, Roller Mills are used throughout the break, sizing, and reduction passages, ensuring a gradual and controlled grinding process. In semolina and corn milling plants, they contribute to the production of high-quality semolina, grits, and flour with consistent granulation characteristics.

OZAN Milling Roller Mills are engineered to deliver exceptional grinding performance, operational reliability, and long-term durability. Their robust construction, precision roll alignment, and advanced control systems provide stable operation, superior product quality, and maximum plant efficiency.

As the most important machine in the milling process, the Roller Mill directly influences flour quality, extraction rates, energy consumption, and overall mill profitability.

OPERATIONAL FEATURES & SAFETY

The Roller Mill is designed to ensure safe, efficient and reliable operation while maintaining high grinding performance. Its robust construction and advanced control systems provide stable operation under continuous working conditions.

Roll Adjustment System

Working Principle

Conditioned grain is evenly fed between rotating rolls where it is crushed or ground according to the required milling stage. The processed product is then transferred to the plansifter for classification and further processing.
