High-pressure roller mill
High-pressure roller mill: the high-pressure roller mills are novel grinding equipment and are gradually becoming the main equipment of the innovative grinding technology due to their advantages of increased crushing and decreased grinding, low unit energy consumption, small floor area, long service life of the wear parts and reliable operation. The high-pressure roller mills are suitable for final grinding of cement industrial raw materials and clinker and the pre-grinding, even the final grinding of brittle materials of the industries of mine metallurgy and chemical engineering, and their applications help realize the purpose of remarkable production increase and consumption reduction.
Applications: the high-pressure roller mills are mainly applied to grinding of iron ores, copper ores, gold ores, diamond ores, molybdenum ores, platinum ores and other technological ores.
Application scheme: three-stage crushing + the ball mill or vertical mill;
four-stage crushing + the ball mill or vertical mill;
applied to autogenous grinding or semi-autogenous grinding
working principle
The
high-pressure roller mill uses two oppositely rotating rollers, one
fixed and the other adjustable, which helps realize effective ore crushing. The
hydraulic cylinder offers extremely high pressure for the system so that
materials can be squeezed and crushed between the two rollers. Based on this
working principle, the high-pressure roller mill realizes ultra-high energy efficiency.
Besides, the roller mill can exert high pressure on materials in a high-degree
control way after materials are fed into the crushing area. The continuous high
pressure incurs microcracks within the ores, which improves the efficacy of the
downstream grinding process. Since the microcracks weaken the ore granularity,
the ores which are not crushed can achieve the final product granularity with
small energy consumption in the follow-up grinding process.
