Slime dryer slime called energy efficient dryer is developed on the basis of the drum dryer developed from the new drying equipment, slime dryer mainly by heat, broken equipment, belt feeder, feed feeding machine, rotary drum, belt out the feeder, fan, unloading and distribution cabinet composition. The main features of a slime dryer, slime dryer strong anti-overload, large capacity, low fuel consumption, low drying costs; 2, the slime dryer drying method used downstream flue gas and wet material from the same side into the drying device, you can take advantage of high temperature gas to get high evaporation intensity, dryer outlet temperature is low, high thermal efficiency; 3, slime dryer operating parameters can be changed depending on the nature of the material, so that the material in the oven dryer cylinder body can form a stable full cut fabric curtain, quality heat exchange more fully; 4, the new feeding of the drying equipment, discharge device, to prevent the drum dryer feed blockage, discontinuous, uneven and return materials such phenomena, reducing the load of dust removal system; new internal structure 5, the dryer, and strengthen the role of cleaning and heat transfer material has been dispersed, eliminating the cylinder wall adhesions phenomenon, material moisture, sticky adapt stronger; 6, slime dryer to achieve a "zero level thrust", greatly reducing wear riding wheel block, cylinder smooth and reliable operation; 7, slime dryer using the "Spherical Roller-type device" so that the idler and roller ring forever linear contact with, thereby greatly reducing the wear and power loss; 8, the drying equipment to control particle size and moisture according to user requirements, when dried slime product moisture up to 8% or less , 8mm or less in particle size can be controlled. Application of energy efficient slime dryer is developed on the basis of the drum dryer developed from the new drying equipment can be widely used: 1, the coal industry coal, coal, flotation concentrate, mixed coal and other materials dry; 3 dry, mineral industry, a variety of metal concentrates, waste, tailings and other materials;; drying 2, the construction industry blast furnace slag, clay, limestone, sand, quartz and other materials dry 4, chemical industry, non-heat-sensitive materials .
