Special coal dryer machine is combined with mechanical hammer mill and centrifugal blower, is less than 20 mm of coal into a fine powder is sprayed into the furnace for combustion, coal consumption, high heat utilization rate.
Drying machine with outer steel shell injection machine. The fuel is coal, is a key source of industrial kiln, pulverized coal injection machine with drying machine is combined with mechanical hammer mill and centrifugal blower, used for crushing coal and combustion will be all kinds of furnace, boiler, kiln, pulverized coal fire spray directly into the combustion chamber (annealing) kiln for factories and mines, enterprises as a variety of kiln supporting institutions.
With the coal machine drying machine will be broken into a coal and coal machinery, it is an important auxiliary equipment of pulverized coal furnace. The coal grinding process is the process of the coal being broken and its surface area is increasing. To increase the new surface area, it is necessary to overcome the binding force between solid molecules, so it is necessary to consume energy.
Special coal dryer machine is widely used in building materials, metallurgy, chemical industry, rotary kiln, drying machine, dryer machine, fixed type furnace, heat source equipment section drying calcination tempering in production, heat source equipment, fuel gas generation and electric heating.
Special coal drying machine is a new type of products and equipment, has the advantages of energy saving, environmental protection, efficient action. The main internal processes for high temperature baking, annealing, flow of air, such as tempering boiler. Injection machine is suitable for all coal-fired heating industry needs high-quality materials, can use heat energy equipment instead of fuel oil, gas, electricity and other related industries, thereby saving energy 60-80%. Coal injection in reducing workload and the number of workers at the same time, effectively improve the overall efficiency reduce the cost.
Performance characteristics:
1, the operation is simple, convenient, only one person can complete the operation.
The 2 day, the amount of coal consumption 30-40%.
3, burn evenly, completely.
4, no black smoke, exhaust emissions can reach the national standard.
Working principle：
First of all substances into the device for grinding roller and the grinding disc, continuous rolling in special equipment for grinding powder. The degree of grinding pressure plays an important role in the efficient recovery of the material in the mill equipment. With the roller loading force, grinding pressure roller, the smaller the coal particle size of pulverized coal particles become more and more small, reduce the load intensity, the particle size increased. On the contrary. However, the strength of the coal mill equipment to increase the load will cause the device to wear too fast, and the life of the grinding device is reduced. Jin Derui drying machine special injection machine with pneumatic conveying, careful grinding, separation process. Drying machine dedicated coal machine equipment heat temperature uniformity in use, no smoke, the separation characteristics of large particles. Can save 60% of the coal burning material, and environmental protection and high efficiency. Coal after crushing coal machine drying machine dedicated the can become very fine particles, wind vane drives water column pressure, the particle drift to realize the burning effect of furnace
