High Pressure Grinder

Brief IntroductionThis machine is a kind of crushing apparatus at medium speed, with complete set, able to form production system independently from block crushing to finished product package. Bag-type duster can reduce environmental pollution, according to environment protection demand.Working principleHyperbaric milling machines, roll grinding hanger on fastening a 1000-1500 kg pressure hyperbaric spring. Roller started work on the rotating spindle, and high-pressure spring and the effects of centrifugal force to keep Central rolling mill, rolling the same dynamic pressure than under the conditions of Raymond Mill powder machine 1.2 times, the yield increased substantially. When the mill was grinding material into the cavity, followed by a shovel blade into the roll grinding and grinding between Central RCC, RCC after the powder with the blower into the cycle of the wind machine, qualified with the powder into the air Cyclones Set-which is refined powder, granular materials down to regrinding. Back to the wind circulation blower to repeat the above process, I go bag filter air purification. When the roll grinding and grinding up to a certain ring wear, high-pressure adjustment spring length, and to maintain roller mill central constant pressure to ensure a stable yield and fineness. Application The machine is suitable for grinding more than 280 kinds of non-inflammable and non-explosive materials with the hardness below scale 9.3 of mohs and the moisture content below 6%, such as barite, limestone, kaolin, ceram and slags, etc, in the trades of mining, metallurgy, chemical engineering and building material for high fine powder generating and processing .
