Working Principle of Pendulum Roller Grinding Mill
The pendulum roller grinding mill is mainly used to make powder (80-400 mesh), which includes elevator, hopper, feeder, mill, classifier, reducer, blower, cyclone collector, pipes and etc. This kind of roller mill is mainly used to grind any non-metal minerals with Moh’s hardness less than 7, for example: calcium carbonate, talc, calcite, dolomite, marble, gypsum, barite, clay, kaolin, quick lime and so on.
The crushed raw material (less than 20mm or 30mm or 40mm) will be loaded into the elevator and then to the feeding hopper. Conveyor will deliver the crushed raw material into the roller grinding mill grinding chamber. Driven by the reducer and transmission shaft, the spider arm, roller assembly and shovels can rotate. In the grinding mill chamber, the roller on the roller assembly will also move centrifugally and the crushed raw material can be ground into powder between roller and ring.
The ground powder will go up through the classifier with help of high-pressure blower. And the coarse powder that cannot go through the classifier falls down to the grinding chamber, which will be reground between roller and ring. The qualified powder will be collected in the cyclone or in the pulse jet collector.
Improved Performance of Pendulum Roller Grinding Mill
The way to increase the efficiency of pendulum roller grinding mill is to lower the wear rate and prolong working life. Firstly: we should feed material with less than 6 Moh’s hardness to protect the pendulum roller grinding mill. Secondly, feeding material size should also be controlled within a range (usually less than 20mm or 30mm); The feeding rate is also needed to be controlled at a even rate. Thirdly, the iron or steel cannot go into the grinding house with a help of electromagnetic iron eliminator. Fourthly, wearing parts are made of wear-resistant alloy material to increase its surface hardness and anti-resistant ability by heat treatment. Most of all, lubrication should be carried out regularly to protect all parts that need to be lubricated.
