Marble pendulum roller grinding mill with open circuit system for no-air pollution

    Marble pendulum roller grinding mill was developed on the basis of traditional Raymond mill. The marble pendulum roller grinding mill is a really highly efficient, energy saving and environment-friendly ultra-large grinding mill with multiple patents. The capacity can reach 25t/h and can fulfill the national industry policy and large-scale industry producing requirement. Marble pendulum roller grinding mill has international advanced technology which largely increase efficiency. Marble pendulum roller grinding mill is able to replace any other facilities, it has the best performance for large-scale powder production. In China, Henkry marble pendulum roller grinding mill has a wide application in thousands of enterprises of manganese, petrol coke, power plant desulfuation, talc, calcium carbonate industry.

Working Principle of Marble Pendulum Roller Grinding Mill:

      Marble powder processing system technological process: marble stone is crushed by the crusher for smaller than 50mm. The crushed marble will be conveyed to the storage hopper by the elevator and then be evenly sent to the grinding chamber. The qualified fine powder will be classified and sent to the pulse-jet dust collector and finally discharged from the dust collector. The product will be transported to powder storage. The Marble pendulum roller grinding mill is designed as open circuit system with full pulse dust collecting (able to collect 99.9% of the powder), so the marble pendulum roller grinding mill has higher output and no pollution.

     Marble pendulum roller grinding mill consists of mill, turbine classifier, pipe system, high pressure blower, pulse-jet collector, feeder, electronic control motor and jaw crusher, elevator. The mill body consists base, air-return box, shovel, roller, ring, housing and reducer. The roller and ring are cast by wear-resistant material.

Improved Performance of Marble 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. As the marble with low hardness, and easy to grind; we make the roller number 3 for small mill and 4 for big mill, this can increase the air volume passing through the grinding chamber, which will increase the output by 15-20%.
3. Improved Reducer: the newly-designed reducer rotation can be adjusted according to customer’s requirement to increase output.
4. Improved Classifier: the turbine wheel use big blade to increase the fineness control, classifying precision and air volume passing area.
5. Bigger size cyclone to increase collecting efficiency.
6. High-pressure blower: air pressure can be increased to make air conveying capacity
