Triple Pass Rotary Dryer Machine

Description of Rotary Dryer Machine

The triple pass rotary dryer is mainly used to dry granular materials within a certain humidity and particle size range. Such as yellow sand, molding sand, slag, coal cinder, small-grained clay, and other small particle materials that are not afraid of high temperature and soot fouling. The moisture content of the dried material can reach 1 to 0.5%. The triple pass rotary dryer is an energy-efficient product that is improved on the basis of a single-cylinder rotary dryer. The unit volume has stronger evaporation intensity and lower standard coal consumption, and is widely used for drying raw materials in industries such as grain, industry and construction.

Application of dryer Machine

1. Chemical, mining, metallurgical and other industries, such as ore, slag, coal, metal powder, clay, earth, kaolin.

2, agriculture, feed, fertilizer industry, such as straw, grass, sawdust, leaves, fish meal, corn, rice, wheat, corn, soy sauce, starch residue, distiller's grains, medical, soy sauce residue, peat, organic compound Fertilizer, sludge, aquatic waste, food waste, abattoir waste, organic fertilizer, inorganic fertilizer, ammonium phosphate.

3. Drying of powdered and granular materials with special requirements. Such as various crystals, light calcium carbonate, activated clay, magnetic powder, graphite, inorganic mud, clay, lime slurry, ore mud, phosphorus slag, aluminum red mud.

4. Low temperature drying is required and a large amount of continuous drying material is required.

Working Principle of Rotary Dryer Machine

1. The material enters the inner layer of the rotary drum from the feeding device to achieve downstream drying. The material is continuously copied and scattered under the inner layer of the copying plate to realize heat exchange, and the material moves to the other end of the inner layer. Middle layer, counter current drying,
2. The material is continuously pushed forward in the middle layer and is in a two-step step backward. The material in the middle layer not only absorbs the heat emitted by the inner roller, but also absorbs the heat of the middle roller, and at the same time prolongs the drying time. The best dry state is achieved here.
3. The material goes to the other end of the middle layer and falls into the outer layer. The material rotates multiple times in the outer drum .The material that achieves the drying effect quickly travels out of the drum under the action of hot air. The wet material that does not reach the drying effect is self-weight. It is not possible to travel quickly, and the material is sufficiently dried in this rectangular copy board, thereby completing the drying purpose.

Features of Rotary Dryer Machine

1. The final moisture of the material is guaranteed to be less than 0.5%, which is the first choice for the dry mortar and slag powder production line.
2. The self-insulation thermal efficiency of the cylinder is up to 70% (the traditional single-cylinder dryer has a thermal efficiency of only 35%), and the thermal efficiency is increased by 35%.
3. The fuel can be adapted to coal, oil and gas. It can bake blocks, pellets and powder materials below 20mm.
4. It reduces the land occupation by about 50% compared with the single-cylinder dryer, the civil construction investment is reduced by about 50%, and the power consumption is reduced by 60%.
5. The required moisture index can be easily adjusted according to user requirements.
6. The outlet temperature is low, and the dust removal equipment is used for a long time.
7. No need for large and small gear transmission, using roller drive.
