INTRODUCTION

    Coal dryer refers to specific coal drying equipment including coal slime, raw coal, Mongolian coal, lignite, long bituminous coal, clean coal, fat coal, froth coal, tailings, medium coal and blue carbon. Different coal characteristics are divided into specific drying process and dryer structure. Customized production, specifications, models, heat sources and other technical parameter solutions are subject to user needs, free installation and technical debugging.

   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.

   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 drying drum divided into the following workaround: one is the feeding area, the coal into the area exchanged with high temperature and hot air quickly evaporate moisture, the material in large Angle of guide plate copy, to be imported under a workspace;2 The 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 achieve the required moisture state, and discharging out;Three is a discharging area, do not set copy plate roller in the region, the material in this area scroll taxiing to the discharge port, then complete the whole drying process.
