OUR COMPANY IS MAINLY PRODUCE CEMENT MAKING MACHINERY,LIKE BALL MILL,ROTARY KILN,ROLLER PRESS,BAG HOUSE,ESP AND ETC
1.General Condition,,,
Model HRM&Model PRM roller mills are new equipment designed by digesting and assimilating advanced technology introduced from other countries.it through grinding rollers to roll and press the materials(0-40mm)on the rotating grinding pan with pressure and grind them to be reached up to the relevant finess.it has good advantages of high griding efficiency.big drying capacity.product finess is easy to be adjusted.low noise,low power consumption,simple process flow.low abrasiveness,operating cost saving and etc.
under the same process conditions and rotating speed.grinding pan diameter material level.grinding roller pressure are all the same,grinding efficency of Model PRM roller mill can be raised more than 30%,average power consumption can be saved about 8.2%,and impact vibration of the overall unital could be obviously reduced.
With international advanced technology and national leading manufacturing quality.it has passed the ministry-level test and listed as state level new preouct in 1995
2.The technical parameter
1.The inlet size is less than 80mm
2.The permited inlet moisture is 6%.
3.The mill speed is 29.75r/min
