China New Type Grinding Mill Stone Grinding Machine

Grinding Mill, Stone Grinding Machine application:

This type mtw grinding mill for sale is mainly used for grinding the material with middle and low hardness, below 6% moisture, and the material should be non-explosion and non-flammability, such as: calcite, chalk,limestone, dolomite, kaolin, bentonite, steatite, mica, magnetite,iolite, pyrophillite, vermiculite, meerschaum, attapulgite, diatomite,barite, gypsum, alunite, graphite, fluorite, phosphate ore, potassiumore pumice, etc

Grinding Mill, Stone Grinding Machine Features:

1. The shovel is made of high manganese steel which is more durable and the blade can replace easily.
2. Cone gear whole transmission-compact conformation, convenient installation, reducing dissipation of energy.
3. Isolation type cyclone powder collector. Effectively improve the efficiency and precision of choosing powder.
4. The observe door and air inlet volute is in the same surface,voiding the eddy current effect and reducing energy consumption.
5. Optimization design for grinding roller grinding ring of main-spring pressurization, high-wearing feature.
6. Internal thin oil lubrication system. Advanced and reliable, prolong service life.
7. Curved duct. Loss of the air volume is small, the liquidity of material is good and not easy plugging material.

Grinding Mill, Stone Grinding Machine Working prnciple

1)Raw material which has been crushed to the size specified is elevated into a hopper from which the stuff is loaded. And then through the vibrating feeder ,the materials will transferred evenly and continuously into the grinding mill grinding chamber for powder-processing. After this,the ground stuff is carried by the air from the blower into the classifer for regrinding.The set's airflow system is closely sealed up and circulated under the condition of negative and positive pressure. 2) The grinding mill is driven by rotation of the central axle through decelerator ,with the up end of the axle connecting to a quincunx-rack upon which the grinding equipment is fixed. The whole set equipment turns together with the axle along the grinding ring while the rollers rotate driven by the fractional force .A set of shovel are installed at the lower end of the quincunx-rack.While turning together with the rollers ,the shovels shed the stuff onto the gap between the rollers and the ring ,and that's where the stuff layer forms .The rotating rollers ,while turning together with the ring ,grind the stuff layer into powder. 3) The turning speed of the impeller can be adjusted to the requirement of the fineness of powder products . 4)grinding mill plays an important role in ensuring the function of the grinder . As the high-speed revolving air current mixed with ground stuff is flown into the cyclone-collector ,the ground stuff is separated from the air-current
