The Horomill can be described as a bed material compression mill, a multi-compression mill and as high capacity mills ( Cornille, 1999 ).
The introduction of high compression grinding technology brought many different applications and circuit layouts using high pressure grinding rolls (HPGR), vertical roller mill (VRM) and Horomills.In ... Details 
Ball Mill. We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements.

Our solutions can handle any type of material, whether soft or abrasive, and typically have a moisture feed of 2-25%. FCB flash dryers are effective solutions for a fine feed size. The addition of our FCB Aerodecantor in closed circuit grinding plants enables flash drying of larger feed sizes, from 4 mm (< about 1/8 in) up to 80 mm (3 in).

Jan 01, 2021 Vertical Roller Mills (VRM), High Pressure Grinding Rolls (HPGR), Vertical Shaft Impact Crushers (VSI) and more recently, Horizontal Roller Mill (Horomill) have saved the specific power by 45–70% when compared with a ball mill circuit [8], [10]. Now a days Ball mills and HPGR are installed together as a common unit.

The long residence time of the gold within the grinding circuit can cause some of the GRG to become nongravity recoverable due to smearing on to grinding media, mill liners and gangue minerals. This effect is minor as more than 98% of the GRG entering the ball mill remains gravity recoverable after grinding (LaPlante, 2000).
Details 
In this respect, grinding technologies such as vertical roller mills, high pressure grinding roll crushers (HPGR) and the Horomill are used in finish grinding of cement in cement plants in the recent years as they are known to be energy efficient systems. Grinding is achieved by high compression in these systems.
