Dryer is a kind of drying equipment for processing a large number of materials, with high efficiency and high output performance is one of the problems that users pay more attention to. With the national concept of energy conservation and environmental protection in recent years, the drying equipment is now paying more and more attention to the improvement of energy saving direction while ensuring the efficiency and output, and reducing the heat loss to a large extent is one of the more important links.

In the process of material drying: wet materials are sent to the hopper by belt conveyor or bucket elevator, and then enter the feeding end through feeding pipe through the feeder of hopper. The slope of the feeding pipe should be greater than the natural inclination of the material, so that the material can flow into the dryer smoothly. The drum of rotary drum river sand dryer is a rotating cylinder slightly inclined to the horizontal line. When the material is added from the higher end, the heat carrier enters from the low end and contacts with the material countercurrent, and some heat carrier and material flow into the cylinder together. With the rotation of the cylinder, the material moves to the lower end under the action of gravity. Industrial dryer as a common drying equipment in the mineral processing industry, in today's rising raw materials, we always adhere to the environmental protection and energy-saving line, so that users can really feel the care from manufacturers, so as to continuously expand the market sales of our dryer equipment.
