Coal Crusher & Crusher

what is the principle of operation of a stone grinding mill

The stone grinding mill mechanical commonly known as the Mill, Raymond Mill.

This stone grinding mill is widely applicable to barite, calcite, potash feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, insulationMohs hardness of materials, etc. is not greater than 7 and humidity below 6% non-explosive minerals, chemicals, construction and other industries over 300 kinds of material for high fine powder generation and processing, R-type Raymond mill finished tablets80-325 mesh within arbitrary regulation, part of the material up to 600 mesh.

Raymond mill Operating Precautions

1:Raymond Mill powder machine should be developed equipment "equipment maintenance safe operation system" in order to ensure the long-term safe operation of the Raymond mill, have the necessary tools for maintenance and grease and the appropriate accessories.
2:Raymond mill roller device usage time over 500 hours to replace the roller when the impact of breaking. Must be cleaned of all rolling bearings in the roller kit, damaged parts should be replaced, the high-pressure mill. The refuel tools can be used to manually add the mining equipment of pumps and grease gun.3:Raymond mill in the course of which should be fixed personnel in charge of the coal pulverizer. The operator must have a certain technical level gravel equipment. Raymond Mill powder machine before installing the operating personnel must carry out the necessary technical training, jaw broken machine. Understand the principle of performance of the Raymond mill, and familiar with operating procedures gravel equipment.4:Raymond mill use for some time, should be carried out for inspection. Roller mill ring blade and other wearing parts, maintenance replacement treatment, mobile crushing plant. Roller device in use before and after the connecting bolts and nuts should be carefully examined crusher price. See if there is loosening grease to add a little spiral sand washing machine.

Raymond Mill Common Faults and exclusion method:

Mill in the course of the failures, according to the following table to deal with the gangue grinder.

1.No powder or flour production is low.
(1):lock the powder feeder is not adjusted, sealing leakage, resulting in pink suck.
(2): blade wear materials shovel can not afford.
(3):The duct blockage
(4): pipeline leak is sealed well.
(5): Check and adjust the lock powder seal and found the leak at the blade.
(6): the replacement of the new blade.
(7): duct material clean-up after re-cutting.
(8): sealed pipe.

2: refined powder is too coarse, or too small.

3: Host current rise in machine temperature rises, the fan current drops.

4: host noise and greater vibration.
