What are the main functions of ultra-fine grinding of coal?

We all know that there is a close relationship between the drying speed of coal pulverized coal powder and the hot air flow, in which the hot air flow speed of the dryer and the flow rate and the drying effect are directly sensed during operation, how can the palm better grasp the hot air flow to dry The important role of materials?

Strengthen the insulation of the cylinder, use the boiling furnace to supply heat, increase the temperature difference of the gas-solid phase, increase the temperature gradient; increase the heating area of ​​the solid phase; increase the hot gas flow rate of the dryer and increase the hot gas flow rate. Providing a hot air flow rate has a significant effect on accelerating the heat rate on the premise that the inlet wet material particle size is kept constant and the design of the boiling furnace is designed. In order to increase the hot air flow rate, it is necessary to rationally design the exhaust end dust extraction system at the tail end of the dryer and the hot air supply system at the head end. The full pressure and air volume of the exhaust fan should be suitable. The whole pressure is too low, the air volume is too small, it will affect the ventilation and reduce the output of the dryer; the full pressure is too high, the air volume is too large, it will increase the power consumption, and it is easy to make the off-gas temperature. Increase and increase heat loss.

Ultrafine Mill professional talk about the structure and the principle of use, this is a professional special dryer, the structure belongs to the cylinder, but some people call it the tumble dryer equipment, the use of this dryer and the general drying Different dryers, whether from the appearance or the basic use, are completely different settings, mainly used in the drying of some coal mines and other materials used in a milling equipment, so the professional name is called ultrafine powder Grinding, from the structure to the use of design materials are very suitable for the processing of these coal mine materials, from the material itself to the use of stainless steel high-strength metal materials, plus coal mines are a special material, it is necessary Designed with higher metal materials, each mine must have a special ultra-fine grinding machine, so the equipment suitable for such large processing is ultra-fine grinding, which is more efficient and more convenient to operate.

It is specially designed for the drying equipment designed by coal mine production enterprises, and is suitable for drying various metal sludges and ores and other materials. The overall design is cylindrical, so as to increase the space used, the internal is welded with a structure to prevent the use of some impurities into other parts, affecting the use of the dryer. There will also be different copying plates in the middle of different angles, changing the internal configuration according to each material. The ultra-fine grinding is used differently, so different parts are arranged. The materials of these parts are used for high temperature resistance. After entering the material, there is no internal friction corrosion caused by different materials. The use of temperature to remove moisture from relatively hard materials such as stones, which is convenient for subsequent processing, is an environmentally-friendly and energy-saving drying equipment. Honggangji on the market is energy-efficient equipment, but the materials used are different because of different fields of use. For example, the ultra-fine grinding dryer is a heat source drying equipment. Together with the internal rolling operation, the material can be fully dried inside.

The structure of the drum is convenient for the material to turn during the rolling process, so that the dry material is more sufficient and used more widely, no matter how wet the material can be turned into a dry substance through the dryer, there is slime, and raw coal, and Clay can do all of this work. In the chemical industry, many substances with sensitive heat can not be operated in the traditional dryer. At this time, special drying plays a role. The coal produced by using these drying equipment Higher quality.
