1-30T/H Pendulum Roller Grinding Mill Ring Diameter 1620mm For 100-400 Mesh Powder

1-30T/H Pendulum Roller Grinding Mill for 100-400 mesh powder

      Pendulum roller grinding mill is mainly used in industries such as glass grinding,rubber , agricultural chemicals, enamel, paint, phosphate fertilizer, papermaking, etc. It is the ideal solution for pulverizing almost any non-metallic minerals with Moh’s hardness below 6 and moisture content below 6%, such as marble, calcite, limestone, feldspar, fluorite, gypsum, talc, barite, dolomite, granite, kaolin, bentonite, bauxite, phosphorite, figuline, black lead, clay etc.

     This pendulum roller grinding mill is space-saving for its vertical structure. It is the ideal grinding equipment for powder industry with the following features: space-saving, high production, extensive application, easy maintenance and reliable performance.

     The powder fineness can be adjusted by the turbine classifier between 100-400 mesh. This pendulum roller grinding mill is a combination of self-grinding and self-classifying. With the internal circulate air, the powder can be efficiently classified by classifier and collected by cyclone. Generally speaking, 80mesh, 100mesh, 200mesh, 325mesh and 400mesh calcium carbonate powder can by produced by pendulum roller grinding mill. In this way.  As this pendulum roller grinding mill is equipped with advance cyclone collector and pulse-jet collector, the whole grinding system is environment-friendly and no powder pollution.

 Working Principle of Pendulum Roller Grinding Mill:

      Raw material is firstly crushed by jaw crusher into certain size (less than 20mm), which are lifted up to the storage hopper by bucket elevator. The vibration feeder then conveys the crushed material at a fixed rate into the grinding chamber of the main unit. The four rollers hung upon the spider-arm are running around the shaft. With the centrifugal force, the four rotational rollers will go around the ring tightly. The raw material is lifted up between the rollers and rings by the blade to grind the raw material into powder.

     The grinded material is blown up to the classifier, through which the powder is separated. Coarse particles fall back down to the mill for regrinding. The needed particles will go into the collector,where products will be collected through the discharge opening. The purified air goes into the fan through the pipe above the cyclone collector. Air stream in all pipelines is negative pressure except for that in the fan and grinding chamber. Air volume in the whole system increases because of the gas from the moisture in the raw material and the air from the flange conjunctions and feeding-in opening. The extra air volume goes into the pulse jet powder collector. The ultrafine powder in the air stream can be collected through the discharging valve.

Improved Performance of  Pendulum Roller Grinding Mill:

1. Roller and Ring are made higher and the shovel is made larger to increase the grinding contact surface and grinding force to increase output.
2. Improved Reducer: the newly-designed reducer rotation can be adjusted according to customer’s requirement to increase output.
3. Improved Classifier: the turbine wheel use big blade to increase the fineness control, classifying precision and air volume passing area.
4. Bigger size cyclone to increase collecting efficiency.
5. High-pressure blower: air pressure can be increased to make air conveying capacity
