Detailed Information on Sand Dryer
The sand dryer is also known as three-pass dryer, which is mainly used to process quartz sand, the pomegranate sand, coal, fly ash, copper sludge, slag, slime, perlite and other bulk material material, as well as the foundry industry with a variety of specifications type of sand, blast furnace slag, clay and other materials of small particle size. Henan Hongxing technicians use the energy-saving technology with European mosaic structure, so that the inner tube and the outer tube form a self-insulation structure, and drum outsourcing insulation materials and stainless steel plate can effectively reduce heat loss and improve thermal efficiency, it belongs to efficient combination three drum dryer.
The features of sand dryer:
In the drying process,sand dryer has certain requirements for humidity and particle size range of particulate materials, it is common in dry mortar industrial sand and foundry industry sand with a variety of specifications. The different sectors has different moisture requirements for the dried materials, the final moisture of the materials can reach 0.5-1% or less, and fully comply with the moisture requirements of the various industries.
The sand dryer is developed on the basis of the introduction of the heat exchange technology of Germany. Three concentric cylinders of different diameters combine and inlaid together in accordance with a certain mathematical relationships and structure. This particular structure is capable of forming an insulation system, so that the heat of inner cylinder surface is able to participate in the heat exchange with the tube materials of the outer layer, the outer cylinder is at the cold end of the hot gas stream, and it is possible to reduce the loss area that cylinder distributes the heat. It makes full use of waste heat, and to increase the heat exchange area, to reduce the heat loss, and finally to improve the thermal efficiency.
