Description

Dryer in the structure of fly ash a unique new form, in the technical performance of similar products in the domestic leading position, mainly for building materials, chemical production of fly ash, clay, slag, coal and ore and other materials baking dry; fly dryer is made up of three concentric circles of different diameters embedded in a combination of each other, as the main body of the dryer. Through both ends of the main level with 4 wheel spin at both ends of the four roller on the infeed end cylinder with fuel, fuel vapor, coal-fired stove and other equipment. The discharge end with dust cover and automatic unloading device. Dust and dust associated pipe, dust removal equipment, feeding equipment and transportation equipment and process conditions according to user requirements be designed. Sleeve three-cylinder dryer drying process is accomplished by being dried feed material from the feed end of the inner cylinder dryer, the material inside the tube through the spiral guide plate into the inner cylinder, located inside the inner cylinder there are many spiral lifting plate, the material through the rotary cylinder, was lifting from the plate and keep aside for vertical movement, the material reaches the left end of the inner cylinder due to the role of self-respect into the tube, the guide plate over the tube body rotation under the effect of tube material pushed gyrus, in the tube under the action of lifting plate moves to the right materials, right up to the tube, the material under gravity into the outer tube. Similarly, the material outside the tube spiral lifting turn back to the left under the influence of plate movement, until the left end of the outer tube. In the block outside the feeding cone under the action of the discharge end of tube into the body.
