Introduction of coal jet machine:

Coal pulverizer is also called coal pulverizer. It is a new type of coal saving and coal burning equipment, which can save coal consumption greatly and eliminate the waste of coal powder.

As a new type of coal saving and coal burning equipment, coal injection machine is mainly used for drying, annealing, tempering boiler, steam and so on. The suitable site of the first handsome coal injection machine, such as: Ma steel factory, foundry plant, rolling mill, steel mill, cement plant, boiler plant, etc., can replace the heat energy equipment of fuel, gas and electric power electric heating, thus saving 40-50% energy. The pulverized coal injection machine can greatly reduce the labor intensity of the personnel, reduce the cost and improve the economic benefits.

The coal injection machine has the characteristics of easy ignition, easy control of furnace temperature and stable product quality. The machine has the advantages of simple structure, compact structure, convenient installation and maintenance, reduced labor intensity and reduced energy consumption. First handsome coal spray machine has high thermal efficiency, increase production and energy saving, coal saving 40-50%, no exhaust gas, and production is not affected by the rain weather, it has brought more significant benefits to the factory.

Principle of coal jet machine:

First, the raw coal enters the grinding area of the grinding roller and the millstone, and is grinded into pulverized coal under the roller mill of the grinding roller. The loading force of the grinding roller is an important parameter for the safety and economic operation of the pulverizer. With the increase of the loading force of the roller, the grinding pressure of the roller mill increases, the pulverized coal is finer, the pulverized coal output is increased, the coal particle characteristic coefficient n becomes larger and the consumption of the pulverized coal is reduced, but the equipment vibration of the mill is aggravated, the wear is too fast and the service life of the grinding parts is reduced. The Shuai pulverized coal injection machine has the characteristics of centralized supply, multistage crushing and transportation. It can save 50% coal and meet the requirements of environmental protection. It is a necessary product to reduce the cost and reduce the pollution index. The raw coal is transformed into a very fine powder after a series of comminution processes, and is transported to the furnace by the pressure of the 150 mm water column to achieve the goal of complete combustion.
