3.Cement Rotary Kiln Main types of dryer:
Rotary dryer Tumble dryer, drum dryer, rotary dryer
(1) Rotary drum dryer, also called rotary drum dryer.
Widely used in building materials, metallurgy, chemical, cement industry drying slag limestone, coal powder, slag, clay and other materials. The machine is mainly composed of rotating body, hoisting plate, driving device, supporting device and sealing ring and other components. It has the advantages of reasonable structure, excellent production, high output, low energy consumption and convenient operation.
(2) Rotary dryer can also be used for compound fertilizer production, drying certain humidity and particle size fertilizer, but also for other materials drying, the conveyor plate distribution and Angle design is reasonable, reliable performance, thus high utilization rate of heat energy, uniform drying, cleaning materials fewer times, convenient maintenance and other characteristics.
(3) Rotary dryer has strong adaptability to materials and can dry all kinds of materials. It is used for drying limestone, clay, pulverized coal and mixed materials in cement plants. It is also used in metallurgy, mining, electric power, chemical industry, food and other departments. Rotary dryer is the most commonly used drying equipment in cement plant. And the equipment is simple and reliable operation, dustproof sealing, convenient maintenance, so it is widely used.
(4) Tumble dryer is widely used in food, feed, chemical, pharmaceutical, mining and other industries. The working process of the equipment is as follows: After the dehydrated wet materials are added to the dryer, the materials are evenly dispersed in the dryer and fully contact with the hot air under the motion of the plate reader evenly distributed in the drum, which speeds up the drying heat transfer and mass transfer. In the drying process, the finished product is discharged from the other part of the dryer under the action of slanting plate and hot air. This machine is suitable for drying all kinds of slag materials with water content less than 85%, such as beer grains, bean dregs, spray-corn husk, coal slime, fruit dregs, etc. It has good effect on developing feed resources, reducing feeding cost and reducing environmental pollution.

5. Maintenance method of rotary dryer:
(1) During the normal operation of the rotary dryer, the temperature of the inlet hot flue gas is 700-800 degrees Celsius, and the temperature of the outlet hot flue gas is 90-150 degrees Celsius.
(2) Check the ring and supporting wheel of the rotary dryer. Whether the lubrication points of the roller bearing are filled adequately.
(3) whether the contact between the ring and the supporting wheel is good, the contact surface is not less than 70% of the width of the ring.
(5) Whether the fastening bolts and anchor bolts of the rotary dryer are loose or broken.
(6) Whether the thrust of each supporting wheel is uniformly upward.
(7) Whether there is vibration, crack or subsidence of the foundation of the rotary dryer.
(8) Whether the retaining wheel rotates flexibly, whether the contact with the ring is good, whether the force is too large to cause the surface of the retaining wheel shining, peeling and bearing heating and other abnormal phenomena.
(9) Whether the rotation of the drum body of the rotary drum dryer is flexible and stable, and whether the seals are worn or leaked.
(10) whether the transmission device vibration, lubrication point oil is sufficient.
