Заводская цена быстро обжигающий лайм ротационный кальцинирующий завод по производству известняка ротационная печь для активного лайма

Product introduction and application

The rotary kiln produced has advanced structure. It can effectively improve preheating effect with its low resistance vertical preheater. After the material is preheated, the feeding decomposition rate can reach 20%-25%, thus can directly make use of 10-15mm fine fraction materials. The reliable airtight two-ends combination squama make the air leakage factor under 10%. The usage of compound refractory reduces radiation loss.Rotary kiln belongs to building material equipment, which can be divided into cement kiln,metallurgy chemical kiln and lime kiln according to different materials.

Advantage Of Rotary Kiln

1.High Automation Level
Its pre-heater with low-pressure loss can improve preheating effect efficiently. After preheating, the resolution ratio of the lime-stones can reach 20~25% when they enter the kiln. Besides, the lime-stones, with fine fraction about 10~15mm, can be used directly.
2.Waste Heat be Reused Effectively
The two sides of the reliable rotary kiln are sealed by the combined scales, which can make the air leakage coefficient less than 10%. Composite refractory materials should be used in order to reduce the loss of radiant heat.
3.Low Energy Consumption
The filling vertical cooler, round or square, can be zoned-ventilation, which can make the temperature of lime-stones in the cooler at about 80°C. As a result, it is very convenient to transport and store. It can also pre-heater the secondary air up to the temperature above 900°C, then the waste heat can be recycled to reduce energy consumption.

The Rotary kiln is mainly composed of kiln shell, refractory bricks, supporting device, supporting device with catch wheel, transmission device, lubrication device, mobile kiln head and sealing device at the end of the kiln.

1. Supporting device: advanced shaft structure, automatic temperature measuring device and electrical heating.
2. Catch wheel: including two kinds mechanical wheel and hydraulic pressure.
3. Gears: single or double. Control the rotating speed by buncher, DE machine and frequency variable motor. Be reliable, energy-saving, and efficient.
4. Kiln shell tire bolster: lower bolster has three types: fixed, zoom and floating. The structure is simple, replacement is convenient and won’t hurt cylinder.
5. Sealing equipment: there are many kinds for choice according to kiln models, including air cylinder edge sealing, spring edge sealing, and graphite block sealing and combination for above. The sealing effect is very good.
6. Kiln head hood: including stationary type and flexible type.
