There dryer belt drying, drum drying, drying box, drying tower several models; coal slime dryer heat source type, power and gas; the material is hot air in the drying process airflow and radiation type, etc., are hot air dryer hot air cylinder moves forward from the rear, full contact with the material, by heat conduction, convection, radiation, heat transfer fully utilized; the heat directly to the material, the material of the moisture in the cylinder body continue to be evaporated into the spout of the wind means a lot of water, wet gas stream is withdrawn to prevent secondary pollution caused by dust efflux; stirred by the spiral, sweep scattered, copy board, to promote the movement of materials to complete the drying process ; countercurrent conduction dehumidifying, avoid drying program to reduce duplication. Dryer can be divided into two kinds of industrial and civil, industrial drying machine, also known as efficient drying equipment or dryer slime dryer, civil dryer is a washing machine, usually after washing dehydration, for removal of clothing and other textiles in the water. Energy-saving dryer elevator to the hopper by a conveyor belt or bucket, and then by feeder hopper through feed pipe into the feed end. Feed pipe slope is greater than the natural inclination of materials, so that the material smoothly flows into the economizer dryer (sand dryer) inside. Dryer cylinder is a slightly inclined to the horizontal rotating cylinder. Material from the higher end added a small slime dryer, the heat carrier to enter the low-end, into countercurrent contact with the material, but also heat carrier and the material together and flow into the cylinder. With the rotation of the drum material by gravity to run to one end than the end. Wet material in the cylinder body to move forward the process, directly or indirectly, the heating medium to the wet material to dry, then the discharge end by the belt or screw conveyor sent. Contact surfaces in the energy dryer (sand dryer) cylinder body wall mounted copy board, its role is to copy the material up and planted, so that the material and increases airflow to improve the drying rate and to promote material forward . Heating medium is generally divided into hot air, flue gas. Heat carrier through the dryer after the cyclone will generally require gas trapped within the material brought down. To further reduce exhaust gas dust content, but also through the baghouse or wet dust collector and then put emissions.
