The working principle and selection of organic fertilizer equipment drum dryer


 How a drum dryer works:The organic fertilizer drum dryer can directly dry livestock manure with a moisture content of up to 70%-80% to a safe storage moisture of 13% at one time. The whole process is carried out in a closed system, thereby reducing the pollution to the environment during the drying process. The equipment is mainly composed of a heat source, a feeder, a feeder, a rotary drum, a discharge machine, a material crushing device, an induced draft fan, a discharger and a power distribution cabinet; Under the flipping of the cloth plate copying device, the material is evenly dispersed in the dryer and fully contacted with the hot air, which accelerates the drying heat and mass transfer. During the drying process, under the action of the inclined plate and hot air, the material is discharged to the star-shaped discharge valve in the other section of the dryer to discharge the finished product.

Purchase Notes:
