High capacity vertical grinding mill equipment Price

The machine is used to grind barite,limestione,ceramics,etc,such non-inflammable and nonexplosive stuff,which the hardness is below 9.3 Mohs and moisture is less than 6% in the trades of mining,metallurgy,chemical engineering and construction material.The fineness size is adjustable in the range of 60-1250 mesh (it can even reach to 2500 mesh).It is possible to produce 10-60 mesh powder through assembling special device in the machine.  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 hoveled 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 finenesspowder 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.

Features:

1. Low Investment Cost. This mill itself can crush, dry, grinding, classifying, so the system is simple, and occupation area is about 50% of ball mill system. In addition, it can be installed outside, so it will reduce a large number of investment costs.

2. Low Operation Cost. High efficiency: roller compacted materials directly onto the grinding disc, so power consumption is low. Compared with ball mill, it saves energy consumption by 30% ~ 40%. Less wear and tear: As the roller is not in direct contact with the disc, and material of the roller and liner is high quality, so life lime is long.

3. High Drying Ability. As the hot air inside contacts directly with the material, drying ability is higher, and it saves energy. By regulating the air temperature, it can meet requirements with diffirent humidity.

4. Simple and reliable operation. It is equipped with automatic control systems, so remote control makes it easy to operate. It is equipmented with one device,which prevents the roller from contacting with the liner directly, and avoids the destructive impact and severe vibration.

5. The stability of product quality. As the material stays in the mill for a short time, it is easy to detect and control the product particle size and chemical composition, to reduce duplication of milling, stable product quality.

6. Maintenance convenience. By reparinging fuel tank, rotating the arm, it is fast to replace the roller sleeve, and liner, and reduce the downtime loss.

7. Environmental protection. It is with small vibration, low noise, and the overall sealing. The system works under negative pressure, so there is no dust going out. It meets the requirements of the state Environmental Protection.

Application:

Application of Hot Selling LM Vertical Grinding Mill LM series vertical grinding mills are widely used in grinding non-flammable and non-explosive materials under 9.3(the Moh's hardness), such as grinding quartz, feldspar, calcite, talcum, barite, fluorite, iron ore, copper ore quartz, slag, cement clinker, zircon sand, fly ash and carborundum, coal, etc.
 

Working Principle:

Vertical grinding mill has two pairs of grinding rollers, each pair of roller composed of two narrow rollers, mounted on the same axis and can rotate at different speeds. There are two circular disc slot, and roller to the tire shape, work pressure in the tank. Disc roller and the relative sliding velocity between small and roller can swing, even if the roller sleeve and the disc after the liner wear can guarantee a good abrasive, will not affect the grinding effect. Roller symmetrical structure, one side can be upside down after use and wear. Material grinding process: hydraulic pneumatic roller device through the pressure applied to the material on the crushing of materials, the materials have been moved to crush the edge of disc, from the disc around the nozzle from the exhaust air to improve these materials to Separator.Meal to separate returns after a concentrated mill, fine powder was collected in the precipitator unloading. In the gas flow is small, the meal can not be increased to enhance air flow, they would fall through the nozzle discharged outside the mill, bucket elevator to be transported to the feeder of Vertical grinding mill and was re-grinding mill feed people.
