The ore tube dryer is a new type of energy-efficient drying equipment independently developed and produced by Hongxing Machinery based on years of accumulated technology, continuous research and exploration, and this type of drying equipment has features of low energy consumption, convenient operation, small footprint, reasonable structure, well-made, good efficiency, etc. The tail of the ore tube dryer has a heat recovery device can be reused, so that the energy is not wasted.
The ore tube dryer produced by Henan Hongxing Mining Machinery Co., Ltd. is mainly used in high-moisture lignite. The moisture content of the lignite is high, which can not be directly milled into the pulverizer. Therefore, a pre-drying equipment is needed as the front-end equipment of the coal mill equipment for pre drying the lignite to satisfy the milling needs of the pulverizer.
When the ore tube drier working, the material to be dried enters the drier, and as the dryer rotates, the material is lifted up by a series of internal fins Lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to The bottom of the dryer, passing through the hot gas stream as it falls. This gas stream can either be moving Toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge End (known as countercurrent flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the dryer known as an indirect-heated type. Often, indirect heated dryers are used when product contamination is a concern.
