Rotary drum dryer Fertilizer dryer industrial rotary drum drying equipment
Rotary drum dryer is a material heating and drying device. Widely used in cement, mining, building materials, chemical industry, drying pulverized coal, limestone, grain, sand, feed, animal manure and other materials. The dryer has the characteristics of high temperature, and can use high temperature hot air to dry the material quickly. The design takes into account the production margin, even if the output is increased slightly, there is no need to replace the equipment.
Working principle
After the wet material is put into the dryer from one end, the material is evenly distributed and dispersed in the dryer under the turning of the sheet cutter distributed in the inner cylinder, and the hot air is fully in contact with the parallel flow (countercurrent), which accelerates the drying heat and mass transfer driving force. During the drying process, the material can be moved to another star-shaped discharge valve of the dryer to discharge the finished product under the action of the inclined sheet and the hot air flow.
Performance characteristics
1, rotary dryer high degree of mechanization, large production capacity, continuous operation
2, the fluid through the cylinder resistance is small, low function consumption
3. Strong adaptability to material characteristics
4, stable operation, low operating costs, good product drying uniformity
5, excellent structure, simple, material through the cylinder resistance running smoothly, easy to operate.
Rotary tumble dryer Mechanical structure and working principle
Direct heat rotary tumble dryer is mainly composed of heat source, feeding machine, feeding machine, rotary drum, discharge machine, induced draft fan, discharger and distribution cabinet. After the dehydrated wet material enters the dryer, under the turning of the sheet distributed in the drum, the material is evenly dispersed in the dryer and fully in contact with the hot air, speeding up the drying heat and mass transfer. In the drying process, the material is discharged to another discharger in the dryer under the action of the sheet with the inclination and the hot air. At present, rotary tumble dryer has been widely used in various fields, such as energy, chemical, building materials and other industries.
