Audited Supplier
Zhengzhou Dingli New Energy Technology Co., Ltd is the most professional, most authoritative enterprise in China, which is engaged in coal drying equipment research and development, which is the only Chinese coal slime drying industry set design, production, sales in the integration of science and technology enterprises. After nearly 20 years of rapid development, Dingli has gradually become the first brand of the Chinese drying equipment industry in China. Our company based on the lignite, washed coal such as high moisture content coal, with the carefully technical research and practice, developed the coal rotary drying drum system, After 20 years drying experience and constant improve in the equipment design, with its advanced technology, high efficiency, low energy consumption, stable operation, convenient operation and maintenance, security, environmental protection, the product are well received by users, more than 100 sets of coal drying equipment running in China and all over the world.
The Coal Dryer uses a special dispersing device to break up the bonded slime and dry it. The contact area between the slime and the hot air is increased, and the heat utilization rate is greatly improved. The dried slime can reduce the moisture to less than 12% at one time, and the dried coal slime can be directly used as a fuel, which makes the coal slime into treasure.
This type of equipment can be used for drying all kinds of coal, lignite, carbon coal, including anthracite, lean coal and poor lean coal, lean coal, coking coal, fat coal, air fertilizer coal, gas coal, coal, and weakly caking coal, not sticky coal, long flame coal, lignite, coal washing, screening, raw coal, bituminous coal, the tail coal, midding coal, etc. Equipment can be made according to the customers' requirements.

Coal drum dryer is mainly composed of hot blast stove, belt feeding machine, drum dryer, belt discharging machine, induced draft fan, cyclone dust collector, bag filter (or wet dust collector) and operation control system. Equipment used downstream drying process, its working principle is as follows: wet material after entering the drying drum divided into the following workaround:
2. Copy plate area, the coal in this area is copying by copy board forming curtain material, the material with good contact with hot air, the moisture in coal rapid evaporation become water vapor, water vapor was siphoned off by induced draft fan, so as to achieve the aim of coal drying;The moisture of coal in this area is less than 15% (or less) under state of loose, after heat exchange the materials achieves the required moisture state, and discharging out.
3. Discharging area, do not set a copy plate roller in the region, the material in this area scroll taxiing to the discharge port, then complete the whole drying process.

1. Reliable operation: The coal dryer achieves "zero horizontal thrust", which greatly reduces the wear of the supporting wheel, and the equipment operates stably and reliably.
2. Make full use of energy: Using the downstream drying method, hot air and materials enter the slime dryer from one side at the same time, which can effectively utilize high-temperature hot air.
3. Energy saving and environmental protection: The coal dryer operates in a fully sealed manner, effectively reducing heat loss and dust emissions. It is also equipped with a multi-stage dust removal system to prevent and prevent again, and provide users with an environmentally friendly site. 4. Intelligent and efficient: Plc intelligent centralized control The system is simple to operate, has high precision, and the tacit cooperation between various equipment greatly improves the efficiency of drying operations.
5. The structure is reasonable and the work is guaranteed: the new internal structure, feeding and discharging devices strengthen the cleaning and heat conduction of dispersed materials, eliminate the adhesion phenomenon on the inner wall of the cylinder, and eliminate the blockage and discontinuity of the feeding. Phenomena such as unevenness and reverse material reduce the load of the dust removal system.
