Drying equipment is also called drier. Used for drying operation, by heating make the material moisture (generally refers to water or other volatile liquid ingredients) vaporizing escape, to get provisions moisture content of solid materials. The purpose of drying is to the needs of the material to use or further processing. Such as wood in front of the production of wooden, wood drying can prevent deformation of products, ceramic blank in front of the calcined two drying equipment drying can prevent crack.After drying of material also facilitate transportation and storage, such as the grain dry to a moisture content of the following, in order to prevent mildew. Due to the natural drying far cannot satisfy the needs of the development of production, all kinds of mechanical dryer has been applied more and more widely.Sand transport by a belt conveyor or bucket elevator to the hopper, then by feeding hopper feeder through a pipe into the feed end. Feed pipe is greater than the slope angle of natural materials, so that the material smoothly flows into the sand dryer. Dryer cylinder installs into a slightly skewed to the horizontal rotating cylinder. Participate in the higher end of the material from the heat carrier to enter the low-end, and a counter -touch material, and also the material with the heating body and flows into the cylinder.Follow cylinder by gravity effect of changes in the material than the end of the operation to end. Wet material in the cylinder body to move forward the process, directly or directly to the heat carrier, the wet material to be monotonous, and then through the discharge end of the belt or screw conveyor sent. In the sand dryer (sand dryer) cylinder body wall mounted copy board, its effect is to copy them and cast materials, the material and the appearance of increased airflow touch to travel and to promote material rate monotonic travel. The heat carrier is usually divided into hot air and flue gas. Heat carrier through the monotony is back; usually demand cyclone gas trapped within the material will be brought down. For further reduction of exhaust gas dust content, but also through a bag house or wet dust collector and then put emissions.china dryer: http://www.crushing-mill.com/dryer-machine/
