Slag drum dryer

The slag drum dryer is a dryer that uses three stacked cylinders instead of a single cylinder, shortening the external dimensions of the dryer body. When the machine is running, the material and hot air flow enter the cylinder from the inside out in sequence, and after reciprocating in a Z-shape inside the cylinder, the material is fully utilized to dry before unloading. The overall structure is compact, reasonable, and simple.

The material enters the inner layer of the drum through the feeding device to achieve downstream drying. The material is continuously picked up and dispersed under the inner layer plate in a spiral motion to achieve heat exchange. The material is moved to the other end of the inner layer and enters the middle layer for countercurrent drying. The material is continuously lifted back and forth in a two-step and one-step walking mode in the middle layer. This material fully absorbs the heat emitted by the inner drum, absorbs the heat from the middle drum, prolongs the drying time, and achieves the optimal drying state. The material travels to the other end of the intermediate layer and falls into the outer layer. The material moves in a rectangular multi loop manner within the outer drum.

The slag drum dryer is suitable for industries such as construction, chemical, and smelting, and can dry various materials such as blocks, particles, and powders. It conforms to the national policy of creating an environmentally friendly and resource-saving society, and is an environmentally friendly and energy-saving product that replaces traditional drying equipment.

Applicable materials for three cylinder drying machine

The slag drum dryer is mainly used to dry granular materials within a certain humidity and particle size range. Such as yellow sand, molding sand, slag, coal slag, small particle clay, and other small particle materials that are not afraid of high temperature and smoke pollution.

1. If the discharge temperature is less than 50 degrees, it can be directly fed into the material warehouse without the need for cooling in the cooling shed.
2. There is no air leakage phenomenon, and the sealing difficulty is completely solved. The installation can be completed within 2 hours.
3. The thermal efficiency can reach up to 80% (traditional single tube dryers only have a thermal efficiency of 32%), improving the thermal efficiency by 48%.
4. Compared to a single drum dryer, it reduces land area by about 50% and civil engineering investment by about 50%.
5. Coal consumption is one-third of that of a single drum dryer, saving 40% electricity.
