pendulum ring roll pulverizer
pendulum pulverizer is widely applied to superfine pulverizing for steatite, calcite, mica, kaolinite, barite, graphite etc, and various types of non-inflammable and non-explosive frangible materials using a mohs’ hardness up to 5 and also the moisture is less than 5%. the product dimensions are adjustable as required in all the different 7-22um(2000-600meash).
superfine pendulum type pulverizer is on the bases of our company production experience for more than 15 years. we absorb advantags from the same trade abroad and at home. we review, research and try on 12 kinds of pulverizers, grinding mills and horizontal hammer crushers. and finally we developed this high-efficiency and low-cost superfine pendulum type pulverizers by investigation and trial.

specifications of superfine pendulum pulverizers
1.simple, safe and reliable.
2.long life of wearing parts.
air supply system
1. use the blower of high wind pressure and little flow.
2. change air-back box design of mill and reduce transversal machine product of bellows volute to satisfy the demand of little flow and large wind pressure. meanwhile, increase steel plate thickness of air-back box, rigidity and intensity.
3. the distribution of air supply pipes must be short and smoothly connect.
pendulum ring roll pulverizer working principle
in the main frame, a 1000-1500kg high pressure spring is fixed to the roller suspender. after the grinder is put into effect, the roller will circumgyrate around the main shaft, and rolls closely against the grinding ring effected by the high pressure is 1.2 degree than raymond mill.
when the stuff is loaded into the grinding cavity, it is shoveled into the space between the roller and the ring for grinding. the grinded powder goes into classifier along with the circulation wind of the blower and the standard fineness powder is guided to the cyclone collector as finished and lager size stuff falls back to the grinder for regrinding. the circulation wind returns to the blower to repeat the above process and the after wind enters into bag dust cleaner for purification.
when there is abrasion between roller and ring, it is recommended to adjust the length of the spring to maintain the constant pressure between the roller and the ring hence to be ensured, the stable output and fineness.
application of superfine pendulum pulverizers
superfine pendulum type pulverizers have enough capacity to produce superfine powder from 100 mesh to 1250 mesh, higher precision of separation and no large granularity to meet the diversifying demands of the customers as well as the market.
the pendulum pulverizers are used to pulverize non-ductile ores, minerals, metal oxide chemical synthetic materials and various kinds of non-inflammable and ono-explosive materials, the hardness of which is below mohs 7 and the moisture less than 6%.
