    Product introduction

    Production capacity: 1-30t/h
    Matching power: 11kw
    Applicable materials: Coal slime, lignite, mineral powder, slag, ore, ore, distiller’s grains, sawdust, pomace, bean dregs, sugar residue.

    Rotary dryer is one of the traditional drying equipments. It has reliable operation, large operation flexibility, strong adaptability and large processing capacity. It is widely used in metallurgy, building materials, chemical industry, coal washing, fertilizer, ore, sand, clay, kaolin, sugar, etc. Field, diameter: Φ1000-Φ4000, the length is determined according to the drying requirements. In the center of the tumble dryer, the breaking mechanism can be avoided, and the wet material entering the drying cylinder is repeatedly picked up and thrown by the copy board on the wall of the rotating cylinder, and is broken into fine particles by the dispersing device during the falling process. The specific area is greatly increased, and it is in full contact with the hot air and dried.

    Performance characteristics

    1.The distribution and angle of the lifting plate of the rotary dryer are reasonable and the performance is reliable, so the heat energy utilization rate is high and the drying is uniform.

    2.The rotary dryer has a large processing capacity, low fuel consumption, and low drying cost.

    3.The rotary dryer equipment adopts a self-aligning tug structure, and the tug and the rolling ring cooperate well, which greatly reduces wear and power consumption.

    4.The dryer has the characteristics of high temperature resistance and can quickly dry materials with high temperature hot air. The scalability is strong and the design takes into account the production margin.

    Working principle

    The rotary dryer is mainly composed of a rotating body, a lifting plate, a transmission device, a supporting device and a sealing ring. The dried wet material is sent to the hopper by a belt conveyor or a bucket elevator, and then fed through the hopper through the feeding pipe into the feed end. The slope of the feeding pipe is greater than the natural inclination of the material so that the material flows smoothly into the dryer. The dryer cylinder is a rotating cylinder that is slightly inclined to the horizontal. The material is added from the higher end, the heat carrier enters from the lower end, and is in countercurrent contact with the material, and the heat carrier and the material are simultaneously flowed into the cylinder. As the rotating material of the cylinder is moved by gravity to the lower end. During the forward movement of the wet material in the cylinder body, the heat supply of the heat carrier is directly or indirectly obtained, so that the wet material is dried, and then sent out at the discharge end through a belt conveyor or a screw conveyor.
