HRM series

The HAZEMAG HRM roll mill is designed for the controlled fine crushing of mineral raw materials. It processes materials such as limestone, clay, gypsum, coal, coke and phosphates and enables reproducible product quality under stable operating conditions. The HRM also provides solutions for moist and sticky feed materials. Compression crushing helps reduce fines generation compared with impact-based crushing processes. The HRM features two smooth, counter-rotating rolls with an adjustable roll gap. Material is drawn into the gap and reduced mainly by compression and shear. This allows products with good to very good particle shape and a narrow particle size distribution to be produced. Hydraulic gap adjustment allows product fineness to be adapted to the application. The HRM roll mill is used primarily in minerals processing and industrial applications where controlled product fineness and low fines generation are required. Compared with impact crushing, compression can cause less surface damage and produce material that is handled more gently during size reduction. Actual results depend on the material and operating conditions.
