The price and working principle of medium speed coal mill

Medium speed coal mill is the professional device to process the accessory materials for blast furnace ironmaking, medium speed coal mill mainly grinds soft coal meagre coal. Vertical mill with high efficiency and high output and energy conservation is the ideal device to be used as medium speed coal mill and the vertical mill can be widely used in the powder making system applied in some industries such as electric power, metallurgy, building material, chemical engineering etc., especially in the powder making system of blast furnace coal injection.

1. The performance of medium speed coal mill

Guilin Hong Cheng intensifies the performance of old type vertical mill in terms of output, energy consumption, dust emission control etc., hence the new type vertical mill can achieve 5-700t/h output, the energy consumption is 40-50% lower, this standard is much higher than the national energy conservation and consumption reduction standard; the mill is equipped with new type roller sealing device and pulse dust collector, 99.9%dust collecting rate can be achieved.

2. The working principle of medium speed coal mill

HLM vertical mill consists of mainframe, feeder, classifier, blower, pipes, storage hopper, electronic system, collecting system etc.

The pressure device in HLM vertical mill is designed and produced by adopting standard modules, the number of rollers in the mill can be 2,3,4, or 6 at most, and the rollers can be installed by adopting the method of permutation and combination to use the fewest standard modules to  produce multiple series of products, the demand for different grain size  and  output can be met.

  The motor drives the reducer to rotate the millstone, the materials which are pushed to the space between rollers and millstone by centrifugal force are crushed, ground and smashed. Then the blower blows the powder to classifier , the large grain size powder falls down to be reground and the fine powder goes into pulse powder collector and is blown out through the pipes as finished product, the purified air is blown out through the pipes  above the pulse powder collector.

3. The price of medium speed coal mill  

Guilin Hong Cheng develops many models of vertical mill according to the features of coal to meet the market demand. We can customize the vertical mill according to customer’s personalized demand for output, grain size, moisture, dust collecting effect etc. to better meet the specific requirements in practical application so that unnecessary devices can be canceled to lower investment cost.

Guilin Hong Cheng always follows the principle of “reasonable price ,high cost performance”, our vertical mill with superior performance  and reasonable price is very competitive in the market and is customer’s first choice.
