The air-gap eccentricity of motor rotor is a common fault of flywheel energy storage devices. Consequently, this paper takes a high-power energy storage flywheel rotor system as the research object, aiming to thoroughly study the flywheel rotor''s dynamic response characteristics when the induction motor rotor has initial static eccentricity.
Roller Press – LNV TECHNOLOGY
Roller Press. The roller press is a highly efficient and energy-saving choice for grinding hard and medium hard materials. It is widely used in manufacturing and/or processing of raw meal, cement, slag non-ferrous metals and iron ore. When upgrading the capacity of ball mill systems, it is the best choice of equipment.
Energy-Efficient Technologies in Cement Grinding | IntechOpen
The energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended. 2.5.
ROP rollerpress · Christian Pfeiffer
The roller press is often used where energy-efficient grinding of large product quantities is required. The two rollers, rotating in opposite directions, exert very high pressure on the material, effectively crushing and weakening the particles by causing micro cracks, so that the subsequent fine grinding is easier.
