The structure of kiln is simple, operate conveniently and reliably in life, less wearing parts, high rate of operation, it is the equipment to calcine high-grade cement in cement plant. Meanwhile, it is also widely used in metallurgical, chemical, construction and other industries. The rotary kiln produced by my company is with strong structure, operation smooth, high-quality products etc and can provide users with advanced high-performance vertical pre-heater, 5 degree cyclone pre-heater. Cement manufacturing consists of raw material grinding, blending, pre-calcining, clinker burning and cement grinding. In short, limestone and other materials containing calcium, silicon, aluminum and iron oxides are crushed and milled into a raw meal. This raw meal is blended and then heated in the pre-heating system to start the dissociation of calcium carbonate to oxide. The meal goes further into the kiln for heating and reaction between calcium oxide and other elements to form calcium silicates and aluminates at t a temperature up to 1450 centidegree: so called clinker burning. The cyclone system is attached to the rotary kiln by a riser duct. Secondary fuel is fed to the riser duct, the main fuel mixture, coal/petcock, fires the kiln. Reaction products leave the kiln as a nodular material called clinker. The clinker will be interground with gypsum and other materials to cement. The equipments we use in this whole production line are vibrating feeder, jaw crusher, impact crusher, cement ball mill, lifer, preheating system, cement rotary kiln and packing machine and so on. All the necessary equipments in this line can be provided by our factory. We have cement production line experts to design specific solutions for your preference.
The unique design guarantees the well mixing of pulverized coal, primary air and secondary air. HJ burner is with high combustion efficiency, powerful push force, large velocity difference that enables the homogeneous mixing of the wind and pulverized coal, Supersonic wind speed, superior flame shaping, high flame intensity and rigidity, stable flame performance. It has been repeatedly verified as a trusted burner with superior energy-saving and productivity improvement performance by more than 168 cement plants.

The cement kiln, also called cement rotary kiln, which is mainly used for calcinating cement clinker, is the main equipment for the new dry type cement production line. This cement equipment is mainly composed of cylinder, supporting device, supporting device with catch wheel, transmission device, lubrication device, mobile kiln head and sealing device at the end of the kiln.
What is Rotary Kiln? Rotary kiln is composed of cylinder, gears, support device, kiln liner and kiln tail sealing equipment, kiln head hood and combustion. Cylinder as heated pivoting part, made of high-quality carbon steel plate. Rotary Kiln Features: 1. Support 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. Cylinder tyre 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. 6. Kiln head hood: including stationary type and flexible type. Working Principle of Rotary Kiln: 1) With a certain slope to the level, the whole kiln body is supported by rollers and fitted with thrust rollers to control up and down movement of the kiln body. 2) Besides main driving unit for driving system, it is also fitted with the auxiliary driving unit so as to ensure the kiln body still can rotating when the main motor is powered off and prevent it from deforming. 3) The kiln head adopts housing type sealing and kiln rear uses axial contact sealing unit so that reliability of sealing could be ensured. Types: Rotary kiln belongs to building material equipment, and it can be divided into cement kiln, metallurgy chemical kiln and active lime kiln, porcelain kiln according, building material kiln, calcined petroleum coke rotary kiln to different materials. Application of Rotary Kiln: 1) Rotary kiln is the Thermal Equipment, heating materials, in cement industry for calcining clinker. 2) It is also used in various industries, such as cement, nonferrous metallurgy, ferrous metallurgy, chemistry, building, refractory material, environmental protection, etc. Export standard container 20GP OR 40GP, 40HQ, FR container, in bulk, the spare parts in wooden case.
