china shanghai micro powder grinding mill introduction:
china shanghai micro powder grinding mill is a leading word level industrial mill. It is designed by our engineers and technical workers, basing on many years industrial mill design, adopting world leading powder making technology. Our machine adopts numbers of national patents of mill, such as trapezium working surface, flexible connection, roll linked pressure boost, etc. It has totally covered many defects of traditional mill, like application, capacity, fineness, energy consumption, service life, etc and it is the ideal substitute of traditional mill, such as high pressure suspension mill, ball mill, etc.
Nowadays, it has been widely used in electric power coal industry, fireproofing, etc. and it has achieved large economic benefits and social benefits.
china shanghai micro powder grinding mill application
china shanghai micro powder grinding mill 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, potassium ore pumice, etc
Technology Advantages of china shanghai micro powder grinding mill
1. Exquisite appearance.
2. The whole bevel gear transmission.
3. Internal thin oil lubrication system.
4. curved duct.
5. Curved surface shovel with exchangable blade.
6. Isolated cyclone collector.
7. No resistance inlet volute (small observation door without vortex).
8.The key components such as roller and ring of MTW series trapezium mill adopt stong wear resistant material.
Working principle of china shanghai micro powder grinding mill
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 rock grinding mill for sale in federal way 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)It 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) china shanghai micro powder 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
The total production procedure is continuous until the machine is shut down
