Ceramic Sand Rotary Kiln

Ceramic sand rotary kiln is a process of calcining ultra-fine kaolin at working temperature (950 ~1050 C). At present, China's technology is mature and advanced, which represents the development direction of ultra-fine kaolin calcination technology. This calcination technology has low energy consumption and high output. The product is dehydrated, decarbonized and whitened, and has stable performance. It can be used in papermaking and coatings industries.

Use/scope of application of ceramsite rotary kiln:

It is widely used in ceramsite, clay, yellow mud, river bottom sludge, fly ash, shale, slag ceramsite rotary kiln, dolomite, kaolin, bauxite, refractory furnace charge, cement, limestone, ilmenite, bauxite, activated carbon, coke, ore powder, alumina, magnesia, zinc oxide, special cement and so on. Calcination and production of ceramsite.

Performance characteristics of ceramsite rotary kiln:

1. It has simple structure, high unit volume, long furnace life, high operation rate, stable operation, high heat transfer efficiency and low heat consumption.

2. Automatic temperature control, over-temperature alarm, waste heat utilization of secondary air intake, long service life of kiln lining.

3. Advanced sealing technology and equipment of kiln head and kiln tail, which has the remarkable characteristics of stable operation and high output.

The technological process of ceramsite rotary kiln:

1. The equipment of ceramsite rotary kiln consists of rotary cylinder, supporting device, supporting device with retaining wheel, sealing device at kiln head, kiln tail and coal injection pipe device.

2. The kiln body is inclined to a certain level. The whole kiln body is supported by a supporting wheel device and has a wheel-retaining device to control the movement of the kiln body up and down.

3. In addition to the main drive, the transmission part is also equipped with an auxiliary drive device to ensure that the kiln body can rotate slowly and prevent the kiln body from deforming when the main power supply is interrupted. The head of Hengchang kiln is sealed by shell and cover, and the end of the kiln is equipped with an axial contact sealing device, which ensures the reliability of the sealing.

4. Calcination of ultra-fine kaolin at working temperature (950 1050 C) to run ceramsite sand, and then adjust the temperature according to the amount of material, finally achieve the desired goal. This calcination technology has been proved by practice: low energy consumption, product dehydration, decarbonization and whitening, and good performance.
