It has the same working principle as Raymond Mill, but its grinding device is fixed with 1000 - 1500 kg pressure springs. When the machine works, the grinding roller, under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure is 1.2 times higher than that of Raymond mill .The pressure of wood pellet mill is determined by the clearance between roller and die. For different materials, you need adjust the clearance accordingly. We recommend you to refer to the operation .

Calculation of rolling pressure distribution and force .

With many grinding mills — including roller mills, rotor mills, hammermills, air-classifier . bed opposed-jet mill's pressure drop is much more complicated than for a hammermill, however. The largest pressure drop occurs when the air passes through the classifier wheel. This pressure .High pressure roller mill is used in mineral industry, building industry, chemical industry and metallurgy industry. It is used for high fineness production of more than 400 kinds of non flammable and non explosive materials of Mohs hardness less than 9.3 richter scale, humidity below 6%, such as quartzite, feldspar, barite, fluorite, dolomite, garnet, carborundum, bauxite, zircon sand, marble .
