High-Speed Uniform Dryer For Mineral Processing, Building Materials And Metallurgy
Product Introduction
Dryers are mainly used for drying materials with a certain humidity or particle size in the mineral processing, building materials, metallurgy, chemical industry and other departments. Rotary dryers have strong adaptability to materials and can dry various materials. The equipment is simple and reliable, so they are widely used. This series of dryers are widely used in: drying of iron oxide sheets, sludge, coke, pig iron filings, copper concentrate, silicon carbide powder, rare earth ore, mercury ore powder, tin ore powder, cobalt ore powder, nickel ore powder, manganese ore powder, gypsum powder, bentonite, kaolin, iron ore concentrate, lead concentrate, petroleum coke, gold ore powder, steel slag, water slag, fluorite ore, sea sand, river sand and other materials.
Structural features
This dryer is mainly composed of a cylinder, a large gear ring, a small gear, a support wheel, a retaining wheel, a wheel belt, a support wheel shaft and other parts. The motor passes through a V-belt, is reduced in two stages by a reducer, and drives the large gear ring through the small gear, so that the cylinder runs at the designed speed, thereby drying the materials in the cylinder evenly.
Main types
Rotary dryer, also called rotary drum dryer. It is widely used in building materials, metallurgy, chemical industry, cement industry to dry slag limestone, coal powder, slag, clay and other materials. The machine is mainly composed of rotating body, lifting plate, transmission device, support device and sealing ring and other parts. It has the advantages of reasonable structure, excellent workmanship, high output, low energy consumption and convenient operation.
Maintenance method
1. Check the hot flue gas temperature of the inlet of the rotary dryer during normal operation, which is 700-800 degrees Celsius, and the hot flue gas temperature of the outlet is 90-150 degrees Celsius.
2. Check the rollers and rollers of the rotary dryer. Whether the lubrication points of the roller bearings are filled with enough oil
3. Whether the contact between the roller and the roller is good, and the contact surface is not less than 70% of the width of the roller
4. Whether there is any crack in the weld between the roller and the pad, and whether there is any excessive wear between the roller and the roller.
5. Whether the fastening bolts and anchor bolts of the rotary dryer are loose or broken.
6. Whether the thrust of each roller is consistent and uniform upward.
