Product Description

This rotary dryer can dry many kinds of materials which contain moisture, such as coal, lignite coal, coal slurry, braise , slag , industrial waste , and clay stone and so on... Rotary dryer are widely used in building materials, metallurgy, and chemical industry. Material to be dried enters the dryer, 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 counter-current 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. In some cases, a combination of direct-indirect heated rotary dryers are also available to improve the overall efficiency. Special characteristics of Lignite dryer: Environmental protection, energy and reducing loss of lignite Improve the calorific value of brown coal, desulfurization, and reduce volatile Investment, small footprint, and supporting civil works less Reliable, simple operation, convenient maintenance, safe and durable Dry and moisture control, minimum up to 5% or less, meet the material widely Even temperature drying process to ensure the quality of lignite change Continuous work and large capacity. Lignite dryer market outlook of Lignite dryer: With implementation of the strategy of sustainable development, coal and other mineral resources, the rational development and utilization has become an important issue, the original low value the full development and utilization of lignite is urgent Use of valuable lignite resources, so that turning waste into wealth, not only can produce considerable economic benefits Taida lignite dryer, can be dry and brown in ensuring the quality of the same premise, reducing the sulfur content of lignite to improve the calorific value of lignite Improve combustion efficiency, making more full use of coal resources Applications include of Lignite dryer: lignite, quality, dry municipal sludge, paper sludge, leather sludge, printing and dyeing sludge, chemical materials and pharmaceutical liquid fermentation residue, food fermentation, sugar residue, rosacea, chemical organic waste, and more Special characteristics of Lignite dryer Environmental protection and energy and reducing loss of lignite Improve the calorific value of brown coal, desulfurization, and reduce volatile Investment and small footprint Supports civil works less Reliable, simple operation, convenient maintenance, safe, and durable Dry and moisture control, minimum up to 5% or less, and meet the material widely Even temperature drying process to ensure the quality of lignite change Continuous work, large capacity Market outlook of Lignite dryer With the implementation of the strategy of sustainable development, coal and other mineral resources, the rational development and utilization has become an important issue, the original low value the full development and utilization of lignite is urgent Use of valuable lignite resources, turning waste into wealth, not only can produce considerable economic benefits Can be dry and brown in ensuring the quality of the same premise, reducing the sulfur content of lignite to improve the calorific value of lignite. Improve combustion efficiency, making more full use of coal resources Lignite dryer Technical Specification input moisture(20-45%) fuel coal heating value≥5500 output moisture(≤15%)
