Rotary 30kw 20t/H Sawdust Dryer Machine For Pig Manure

Rotary Drum Dryer Used For Drying compound fertilizer, chicken manure, pig manure, sand, stone

Introduction:

The machine adopts the advanced roller and plate structure. After the material enters the cylinder, it is continuously scattered in the hot air flow under the action of the plate, so that the surface of the particles can fully contact with the hot gas, so as to achieve the best drying effect and complete the drying process I of the materials. It is widely used in building materials, metallurgy, chemical industry, cement industry drying slag limestone, coal powder, slag, clay and other materials. The machine is mainly composed of rotary body, lifting plate, transmission device, support device and sealing ring. It has the advantages of reasonable structure, excellent production, high output, low energy consumption and convenient operation. The machine can also be used for compound fertilizer production, drying fertilizer with certain humidity and particle size, as well as drying other materials. The distribution and angle of the lifting plate of the machine is reasonable, and its perform.

The distribution and angle of the lifting plate of the machine is reasonable, and its performance is reliable. Therefore, it has the characteristics of high utilization rate of heat energy, uniform drying, less times of cleaning materials, and convenient maintenance.The inner wall of the cylinder is equipped with a copying board. Its function is to copy and scatter the materials, so as to increase the contact surface between the material and the air flow, so as to improve the drying rate and promote the material to move forward. Heat carrier is generally divided into hot air, flue gas and so on. After the heat carrier passes through the dryer, the cyclone dust collector is generally needed to capture the materials carried in the gas. If it is necessary to further reduce the dust content of tail gas, it should be discharged after passing through bag filter or wet dust collector.

working principle:

The dry wet material is sent to the hopper by belt conveyor or bucket elevator, and then enters the feeding end through feeding pipe through the feeder of hopper. The slope of the feeding pipe should be greater than the natural inclination of the material, so that the material can flow into the dryer smoothly. The dryer cylinder is a rotating cylinder slightly inclined to the horizontal line. When the material is added from the higher end, the heat carrier enters from the low end and contacts with the material countercurrent, and some heat carrier and material flow into the cylinder together. With the rotation of the cylinder, the material moves to the lower end under the action of gravity. When the wet material moves forward in the cylinder, the heat is directly or indirectly obtained from the heat carrier, so that the wet material can be dried, and then sent out by belt conveyor or screw conveyor at the discharge end.

Advantage:

1, The drying time is short.
2, The drying intensity is high, because the material is highly dispersed in the air flow, the whole surface of the particles is the effective area of drying.
3, Large capacity and high thermal efficiency. When the unconjugated water is dried, the thermal efficiency can reach 60%.
4, The dryer is simple in construction and maintenance, and easy in construction and maintenance.
5, The dryer realizes "zero horizontal thrust", greatly reduces the wear of the supporting wheel, and the cylinder runs stably and reliably.
6, The dryer adopts "self-aligning supporting roller device", which makes the matching of supporting wheel and rolling ring present linear contact forever, thus greatly reducing wear and power loss.
