Introduction of Ceramic Sand /Taoli sand Rotary Kiln
Ceramic Sand Rotary Kiln is crucial equipment when producing high quality ceramic sand.

Characteristics of Ceramic Sand / Taoli sand Rotary Kiln
Ceramic Sand Rotary Kiln has simple structure, convenient and reliable control during the production process, a few wearing parts, and high operation ratio. The rotary kiln produced by our factory has rugged structure, smooth operation, and high quality outlet products. Besides, we provide our customers with advanced, efficient vertical heating device, and cyclone heating device.

Working Process of Ceramic Sand / Taoli sand Rotary Kiln: 
1. Crushing and Milling
The dry crude material will be crushed and milled first.

2. Calcination
After milling, the materials would enter the kiln outlet (high end of the cylinder) through the preheater, and then are fed into the kiln by the tremie pipe.  Meanwhile, the heating source is sprayed into kiln by burner barrel in the head of the kiln. Due to the inclination of the cylinder and slow rotation of the cylinder, the materials roll in hoop direction. During this process, They will be calicinated, reacted, decomposed in succession through the calcinating section, reaction section, decomposition section, Note: The exhaust gas are discharged by the exhaust blower and drained into the atmosphere by chimney after exchanging heat with the materials.

3. Cooling    
Then the materials are discharged from the head of the kiln and enter the cooling device and cooled.

4. Screening
Then they will go through the screens and final products will be conveyed to the yard. The big size materials will be sent back and processed.

Brief introduction of our company rotary kiln: 
CITICHL is one of the largest design and manufacture enterprises for rotary kilns in China, which started producing in 1950s. We have totally produced more than 250sets of rotary kilns including dry, semi-dry and wet ones used widely in cement, metallurgical, chemical industry, refractory, active lime, paper-making etc. Specifications are from Φ1.2 to Φ6.1m. They have been exported to Thailand, Pakistan, Indonesia, Vietnam etc.
Our company has absorbed technologies from famous international companies such as Smidth, Polysius, KHD, etc. In recent years along with the advances in cement producing, cooperated with design institutes in Tianjin, Nanjing etc, developed new large serial products of dry processing rotary cement kilns, matching 1000-5000t/d large and 8000-10000t/d extra-large cement production line. There have been nearly hundred sets put into operation in the cement plants of Anhui, Hailuo, Jilin Shuangyang, Indonesia Kupang etc.
Our company has the first-rate group on rotary kiln development, study and design, perfect experiment and testing measures, and superior manufacturing equipment and technology for large rotary kiln, while has formed the complete technical and producing system on the design, manufacture, installation, commissioning service for the equipment.
