Dolomite Rotary kiln is widely used to process solid materials mechanically and chemically in the industries such as building materials, metallurgical extraction, chemistry, environment protection. Rotary Kiln has a fortified structure and can produce high quality products. What'smore, our company provides our customers with efficient shaft preheaters and five-grade cyclone preheaters.
Dolomite Rotary kiln machine operating principle:
The rotary kiln is made up of gas flow, fuel burning, heat transfer, and material movement etc process. The rotary kiln is to make the fuel fully burning, the heat from which can be effectively pass to materials, so that material can produce series of physical and chemical changes after receiving the heat, finally forming finished product chamotte.
Dolomite Rotary kiln machine features:
The rotary kiln is composed of cylinder, supporting device, sealing device, and feeding device and kiln head combustion equipment etc. The rotary kiln is a circular cylinder, which is installed on several pairs of tugs inclined. After the motor decelerating, the cylinder revolves around by the small gear driving big gear.
The Rotary kiln is the main equipment of calcining cement clinker, which has been widely used in cement, metallurgy, and chemical industry. The equipment is composed of cylinder, supporting device, supporting device with catch wheel, transmission device, active kiln head, kiln end sealing device, burning device etc components. The rotary kiln is featured by simple structure, reliable operation, and easy control in production process etc.
The rotary kiln produced by ZK has the calcining system equipment through technology innovation, which adopts the most advanced hydraulic catch wheel, high precision of measurement piston pump, flow speed control valve, and contact graphite piece of sealing device at home and abroad, In order to improve the degree of automation, kiln head adopts industrial TV watching fire, analog fluorescent screen for process flow, and calcination zone adopts the infrared scanner, directly reflecting the calcination situation in computer . All these new technology has a strong intuitive sense in use, easy to operate. Reliable and stable thermal condition improves the operation rate of the equipment.
