Mineral Powder 20t/H 6kw Sawdust Drying Systems

Drum Dryer Used For Drying Sand, Mineral Powder, Slime, Chicken Manure, Cow Manure

Introduction:

Rotary dryer is generally suitable for granular materials, and can also be used for drying sticky paste materials or materials with high water content by partially mixing materials. Its advantages are large production capacity, wide application range, small flow resistance, large allowable fluctuation range in operation, convenient operation, etc. It is commonly used for drying sand, mineral powder, slime, chicken manure, cow manure, etc.

Rotary dryer also known as rotary dryer, rotary dryer, is a large number of materials processing dryer. It is widely used in metallurgy, building materials, food, light industry, chemical industry, coal, medicine and mining industry due to its reliable operation, large operation flexibility, strong adaptability and large processing capacity.

The dryer is mainly used in mineral processing, building materials, metallurgy, chemical industry and other departments to dry materials with certain humidity or particle size. Dryer equipment has strong adaptability to materials, can dry various materials, and the operation of the equipment is simple and reliable, so it is widely used.

Used in building materials, metallurgy, chemical industry, cement industry drying slag limestone, coal powder, slag, clay and other materials. The machine is composed of rotating body, lifting plate, transmission device, supporting device and sealing ring. The utility model has the advantages of reasonable structure, high output and low energy consumption. This machine can also be used for compound fertilizer production, drying humidity and particle size fertilizer, and also can be used for drying other materials. The distribution and angle of lifting plate of the machine are reasonable, so the utilization rate of heat energy is high, the drying is uniform, the number of cleaning materials is less, and the maintenance is convenient.

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. High dryness, because the material is dispersed in the air flow, the total surface area of the particles is the dry area.
2. Short drying time.
3. The air dryer has the advantages of simple structure, small floor area and easy construction and maintenance.
4. Large capacity and high heat rate. When the unconjugated water is dried, the heat rate can reach 60%.
5. The dryer 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, so as to reduce wear and power loss.
