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 …
High-pressure roller press, also known as extrusion mill, roller mill or roller press, is a new type of cement energy-saving grinding equipment. This equipment can replace the traditional ball mill pre-grinding system with high energy consumption and low efficiency, and at the same time it can reduce steel consumption and working noise.
