Vertical industrial coal drying furnace also called vertical desiccator, vertical drying machine is not based on the traditional Vertical Drying Machine is transformed and be become. But without chapter in the condition, facing follow today type coal drying furnace widespread investment, big covers an area of big failure rate, according to the condition of high offers under low temperature, use coal drying characteristics of great air-delivery and gravity principle, the development design, industrialization test, product generation upgrades, put into operation of massive mold several stages, lasted for several years and successful products. In the design, fully embodies the applicable innovation, expand efficiency, reduce cost, improve quality. Safety production and environmental protection are an ideal equipments for Vertical Drying Machine.
