Drying equipment is mainly used to dry granular materials within a certain humidity range, such as yellow sand used in the dry powder mortar industry and various specifications of molding sand used in the casting industry. Blast furnace slag used in the building materials and cement industry. Small particle clay is used in the chemical industry for small particle materials that do not undergo chemical changes, are not afraid of high temperatures, and are not contaminated by smoke and dust. According to the moisture requirements of different industries for dried materials, the moisture content of dried materials can reach below 1-5%. /Idle second-hand compound fertilizer dryer set
The materials entering the dryer should not stick to the cylinder wall or the poplar board. The temperature of the gas entering the dryer for heat exchange should not exceed 750 degrees Celsius,

Working principle of second-hand dryer/Idle second-hand compound fertilizer dryer set
Various types of drying mechanisms have similar functions, mainly consisting of a rotating body, a lifting plate, and a transmission device,
Composed of supporting devices and sealing rings. The dryer is a cylinder slightly inclined from the horizontal direction,
The material is added from the higher end, and the high-temperature flue gas flows into the cylinder together with the material. As the cylinder rotates,
The material moves to the lower end due to the effect of gravity. A copying plate is installed on the inner wall of the cylinder to pick up and sprinkle materials
To increase the contact surface between the material and the airflow, in order to improve the drying rate and promote the forward movement of the material. The dried product is collected from the bottom and lower part.

1. Chemical, mining, metallurgical and other industries, such as ore, slag, coal, metal powder, clay, diatomaceous earth, kaolin.
2. Agriculture, feed, and fertilizer industries, such as straw, grass, leaves, fish meal, corn sauce, starch residue, distiller's grains, medicine residue, fruit residue, soy sauce residue, sugarcane bagasse, peat, organic compound fertilizer, sludge, aquatic product waste, food factory waste, slaughterhouse waste, organic fertilizer, inorganic fertilizer, phosphate fertilizer, and ammonium sulfate.
3. Dry powdered and granular materials with special requirements. Such as various crystals, lightweight, active clay, magnetic powder, graphite, inorganic mud, clay, lime slurry, ore slurry, phosphorus slag, and aluminum plant red mud.
4. Materials that require low-temperature drying and require continuous drying in large quantities.
The sawdust drum dryer is one of the traditional drying equipment, which operates reliably, has high flexibility, adaptability, and processing capacity. It is widely used in metallurgy, building materials, chemical industry, coal washing, fertilizer, ore, sand, clay, kaolin, sugar and other fields
