Introduction

煤泥烘干机.jpg


The raw materials of coal slime, copper ore mud, and phosphate ore mud have high humidity and high viscosity materials, which are not easy to be dehydrated and easy to stick during the drying process. Special dryers and rotary drum horizontal dryers have manufacturing structures. Obvious difference, and is equipped with material bonding rapping device. The high-humidity and high-viscosity materials are fed into the dispersing and feeding device of the connecting cylinder of the special dryer through the belt conveyor. After the block material of the rapid dispersing and feeding device enters the connecting cylinder of the dryer, the material passes through the following tasks Area: The first is the guide area, where high-humidity and high-viscosity materials enter this area due to the function of the guide spiral plate and the high-temperature negative pressure hot air, quickly evaporate a large amount of water, and the material is fed into the connecting cylinder by the guide spiral plate The next area; the second is to clean up the broken material area. In this area, the material passes through the cutting board and the broken board to turn the large blocks into small and medium blocks, and the material curtain state is formed under the rotation of the dryer, plus a special dryer With the external rapping device, the falling material can no longer adhere to the cylinder wall and the material board. With the gradual dehydration of the material, the collision of the small and medium-sized material balls also plays a role in breaking, thereby increasing the heat of the material. The exchange area improves the efficiency of heat and mass transfer and speeds up the drying speed of materials; the third is the secondary crushing area of materials, this area is the medium temperature drying area, and the materials are in a low-moisture and loose state in this area. , The lumps and lumps of the material are very small. Due to the exhaust gas of the dryer, the dehydration speed increases. After the heat exchange, the material has reached the final moisture requirement and gradually enters the low-temperature discharge area; the fourth is the low-temperature discharge area, drying The machine is equipped with three-angle lifting plates in this area. With the rotation of the dryer, the material passes through the three-meter lifting material into the blanking bag at the tail of the dryer, and then is sent to the material warehouse through the conveying equipment to complete the whole drying process. Dry process.



Features of MN dryer

      1. The special dryer has a special manufacturing structure than the traditional tumble dryer. The connecting cylinder is equipped with a device for dispersing and breaking materials, which makes it difficult for the materials to stick when forced feeding.

      2. The special dryer has strong anti-overload ability, good anti-adhesion effect, large processing capacity, and special angle of the material breaking and lifting plate.

      3. Adopt downstream drying, high temperature flue gas and materials flow downstream, long heat exchange time, high thermal efficiency, fast water evaporation, outlet temperature 60~110℃.

      4. The special dryer can change the speed of the dryer and the operating parameters of the material according to the properties of different materials, so that the material will form a stable section in the dryer, and the heat exchange will be more sufficient.

      5. Special rapping and breaking plate devices are used to prevent high-humidity and high-viscosity materials from sticking to the cylinder wall and the material board in the dryer.

      6. The dryer adopts the "aligning roller device", which makes the surface matching of the roller and the tyre linearly combined, thereby reducing wear and power loss.

      7. The new internal manufacturing structure strengthens the cutting and heat conduction of high-humidity and high-viscosity materials, and eliminates the bonding phenomenon between the inner wall of the cylinder and the feeding board and the lifting board, ensuring that the material reaches the dryer in the dryer. Dry downstream and smoothly.
