Industrial Rotary Dryer Introduction
Our mineral rotary dryer is special designed for drying various mineral raw materials. The external drying host adopts multi-layer heat preservation technology. According to the characteristics of mineral materials, special lifting and cleaning devices are set inside to prevent materials from sticking to the wall, fully realize mass and heat exchange. The mineral materials can be dried quickly with low cost. The drying time and temperature can be controlled in the whole process. Besides, the operation cost is greatly reduced, and the comprehensive economic benefit is improved.
Performance Features of Mineral Rotary Dryer
1. The inner part of the mineral rotary dryer is made of wear-resistant manganese plate, which is 3-4 times more wear-resistant than ordinary steel plate.
2. The initial moisture content of the material is 15%, and the final moisture content after drying is less than 0.5-1%, which can be used as slag powder of cement plant, dry and wet mortar production line, etc.
3. Adopt special heat preservation system, the thermal efficiency of the mineral rotary dryer is increased by more than 40% compared with the traditional dryer.
4. The fuel has wide applicability, and the low quality fuel coal can be used.
5. There is no air leakage phenomenon, and the sealing difficulty is completely solved.
6. The discharge temperature is less than 60 ºC, it can be directly fed into the warehouse without cooling.
7. The temperature of the outer drum is less than 60 ºC, the temperature of the exhaust gas is less than 120 ºC, and the service time of the bag of dust remover is more than 2 times longer.
Mineral Rotary Drum Dryer Application
The mineral rotary dryer is special designed for drying bentonite, clay, limestone, gold ore, iron ore, pyrite, river sand, copper ore and other materials. It is widely used in mineral processing, metallurgy, building materials, chemical industry and other industries.
Working Principle of Mineral Rotary Drum Dryer
Mineral raw materials are delivered into the hopper by belt conveyor or bucket elevator, and then enter into drying system by feeding mechanism. The guide device installed in the rotary dryer will lifts the materials to the top and drops them. The materials are broken by the high-speed rotating blades in the dryer when falling down. It is repeated until move to the outlet. At the same time, the hot air generated by the high temperature heat source enters into the dryer to fully contact with the materials, so that the materials are dried quickly, and then discharged through the conveyor at the discharge end.
