Improving fertilizer manufacturing efficiency by rotary dryer


The rotary dryer is the main energy-consuming equipment in the organic fertilizer production line. Only when the dryer reaches the operation state of high quality, high yield and low consumption, can the loss be reduced and the production income be maximized. The traditional rotary dryer has been in a low-efficiency working state: low output, high energy consumption, low thermal efficiency, high water content and difficult to control.

From the point of view of optimization of rotary dryer itself, the efficiency of organic fertilizer production line can be improved by improving the performance of the dryer itself.

Our factory designed a kind of drying machine with combined lifting board, which avoided many disadvantages of traditional rotary dryer. There are many problems in the structure of traditional drum dryer, which affect the drying effect.

The material dispersion of traditional dryer is low on the cross section of cylinder. The dryer mounted lifting plate forms a wind tunnel on the section of the cylinder body, and the materials are only distributed in part of the space. When the material falls down, it will accumulate on the L-shaped lifting board for a period of time. Only the surface material contacts with hot air, and the material inside the stack can not contact with hot air, so the material has low dispersion on the cross section and can not fully contact with hot air.

Traditional rotary dryers have wind tunnels from front to back. The cylinder is equipped with lifting chatterboards of the same specification from front to back. The wind tunnel will extend from the feeding end to the tail. Some hot air can not exchange heat and is discharged directly through the wind tunnel.

The new rotary dryer adopts combined lifting plate, which improves the dispersion of materials on the cross section of the cylinder, reduces the wind tunnel from front to back, improves the heat transfer efficiency of fertilizer particles, and reduces the energy consumption of the organic fertilizer production line.
