Details of the operating principle of Horomill ® as compared to HPGR and vertical roller mills are given by Cordonnier (1994) and Buzzi (1997). The energy saving of this mill is claimed to be similar to that of HPGR and 3050% lower than a ball mill ( Cordonnier, 1994 ).
Principle. The principle of the roller mill is breaking and crushing actions are achieved mechanically with the application of pressure. Stress is applied by rotating heavy corrugated wheels (mullers or rollers). The oil is squeezed out from the solid material. Construction. The construction of a roller mill is shown in Figure.
Advantages of Roller Mills. 1. Produce more uniform, fewer fines, and oversized particles when it comes to product quality. 2. Generates less heat (0 3 0 C) unlike hammer mill that generates up to 10 0 C. 3. Less moisture loss. 4. Better work environment due to low machine noises level.
A New Grinding Process. HOROMILL® A. CORDONNIER FCB, CRCM Centre de Recherches Cimenterie et Minéralurgie Lille, France. Abstract: FCB has just developed a new mill, HOROMILL®, for grinding cement, raw meal and minerals. This new grinding process is designed for finish grinding and also for pregrinding. The energy saving is similar as roll press, roughly 30% to 50% in respect to the ball ...
This new grinding process is designed for finish grinding and also for pregrinding. The energy saving is similar as roll press, roughly 30% to 50% in respect to the ball mill, but with a moderate circulating load and grinding pressure. After a research phase on a 1 t/h pilot plant, a first 25 t/h industrial plant was achieved in cooperation ...
