Chaeng-GRMR Raw Vertical Mill

Also known as raw material vertical mill is core of the device used in cement raw material grinding . It has high grinding efficiency, low power consumption, low noise, small dust pollution, etc., is a new high efficiency, energy saving grinding equipment. Chaeng produced GRMR series of mill, the production capacity of up to 720t / h, a single electrical energy consumption is generally 7.8 ~ 8.3 kWh / t, energy-saving effect is very significant to meet 1000-10000 t / d cement production line of raw material supply.

suitable type of business: Cement Factory

Yield: 70 ~ 720 t / h

fineness: 80μmR 12 ~ 15%

single electrical energy consumption: 7.8 ~ 8.3 kWh / t

Product advantages:

1, vertical mill save electrical consumption 30% to 40% compared with ball mill

According to the measured data show that the production of raw materials, using a vertical roller mill machine production per ton of raw material than the traditional tube mill can save more than 30% of electrical energy consumption alone is generally 7.8 ~ 8.3 kWh / t, energy-saving effect is very significant.

2, the noise is not more than 90 db

Vertical mill roller at work and can not directly contact friction linings, nor a ball mill balls collide, the impact liner metal crash, so the noise is small, less than the ball 20 ~ 25dB.

3, metal consumption per unit of product can be as low 5g / t

Since the vertical mill running roller and disc no direct contact between the metal wear, metal consumption per unit of product is generally 5 ~ 8g / t, we can guarantee the roller, when the lining life of 6000h or more.

4, the effective diameter of the disc can reach 6.3m, with a 720t / h of clinker production capacity

Chaeng independent research and production GRMR63.61 vertical roller mill is made large raw material vertical mill, effective disc diameter of 6.3 meters, the number of up to six grinding rollers, with 720t / h of clinker production capacity greatly improved the grinding efficiency.

5, allowing moisture into the mill up to 7% higher

Vertical mill hot air transportation of materials, when grinding materials with large water inlet temperature can be controlled, it can be dried into the ground water up to 7% of the material, so that products meet the requirements of low moisture content.

6, the product fineness up 80μmR 12-15%

Separator DC motor drive, change the speed to satisfy the conditions of the product fineness requirements. Also of milling products are relatively homogeneous particle size, typically 0.008mm sieve control about 12% of the raw material to meet the rotary kiln fineness requirements too small not only reduces the yield, but also a waste of energy, resulting in pressure poor poor control.

working principle:

Material through the feed tube falls under the central disc, a constant rotational speed of the disc by means of centrifugal force outward uniformly dispersed raw materials, paving, to form a certain thickness of the material bed, the material on the disc simultaneously by a plurality of grinding rolls rolling, and pulverized. In continuous material continuously driven centrifugal disc to the outer edge of the movement, when the material leaving the disc encountered by air ring into the hot gas within the mill and rise by the middle of the mill housing into the separator, in this process the material with the hot gas had a full exchange of heat, moisture quickly evaporates. Separator export controls roll mill product size, larger than a predetermined size particles are separated and fall back to the disc, to meet the requirements of the fineness of the material through the separator into the finished product warehouse.

Structural features:

l.composite separator improves separating efficiency.

2.with automatic roll lift, roll off function, can achieve no-load start.

3.using arc welded seal plate, simple and reliable structure, good sealing effect.

4.With the turn roller device can easily be dug outside the roller mill to facilitate maintenance.

5.mechanical stops to avoid a direct disc rollers and metal friction and collisions, enhancing the use of security.

6.hydraulic system operating pressure is low, to reduce oil leakage, reducing vibration mill, is conducive to the operation and management.

7.roller bearings with thin oil lubrication cycle, to ensure that at low temperature bearing grease and clean working conditions, effectively extending the service life of bearings.
