Cement Rotary Kiln Burner

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.

Cement rotary kiln. According to your needs.

Cement mill is mainly used in grinding of cement finished product and materials, also to the metallurgical, chemical, electricity and other industrial and can be used to open streams, but also to the composition and the separator flow grinding circle. Cement mill has a strong adaptability of materials to production, broken rate large, easy to speed grinding fineness of the product and so on. Ball mill of cement production is capable of dry production and also can be wet. You can simultaneously grinding and drying operation. Our products special features: 1. The finished product has high fineness and large specific surface. Compared with other enterprises in the same industry, the cement produced by our cement mill has the advantage of high fineness and large specific surface. The cement has excellent quality, high hydration reaction speed, fast strength development, and good intensity after hardening. 2.High efficiency and large output. We have rich experience on the manufacture of cement mill, and our technology take a leading place in the industry. Compared with other products in the same industry, the output increases by 15-20%, power consumption reduces by 10%. Moreover, the temperature of finished product can reduce by 10-20 Cement ball mill is mainly consisting of feeding device, big gear, discharge device, cylinder, diaphragm plate, hollow shaft, liner, drive device and other components.

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.

Gas Burner is research and developing for rotary kiln that burning with single or various gas fuel, which not only ensure all the advantages and specificity of four-channel burner, but also enhance the application of burning. The burner have special structure and reasonable technical parameters, guarantee the gas fuel fully mixing with air, primary air and secondary air, which to ensure stronger heating intensity, higher burning efficiency, easier adjustment. Burner can be applicable for various metallurgy and chemical rotary kiln. Application Burning System for Rotary kiln on industry fields like Power, Chemical, Metallurgy, Building material etc. Its special advantages as follows: 1.Stability flame with regular flame shapes, no phenomenon like fluctuation and sweep kiln liner, that will outstanding extend the life time of kiln liner.  2.Good mixing performance with gas fuel, primary air and secondary air, burning abundantly, that can be enhance heating intensity and reduce primary air proportion at same time, then will improve kiln capacity and reduce energy consumption.  3.No strong eddy between flame and bowl effect produced by flame cover, can avoid appearance of temperature peak and make evenly distribution of flame temperature, then effectively protect cylinder and guard plate of kiln inlet. 4.Due to more fully mixing with combustion air and fuel gas, the burning will be more quickly and fully, which will reduce the content of CO and NOX from kiln inlet, but also better for safety operating and realizing green production.  5. The nozzle has made by special material with advantages like heat-resistance and easy to change. 6.Simple operation and adjustment. When operating, erupt speed of each air pipe can be change via adjust sectional area, then will realize goals like adjustment of flame shape and strength. Gas Burner is mainly composed with Pipe, Nozzle, Ignition device, Metal corrugated compensator, Butterfly valve, Pressure measurement and Protection layer etc. The mainly features are: 1. Pipeline From outside to inside respectively, the pipeline has consist of Axial wind channel, Swirling wind channel, Gas wind channel, central wind channel and ignition channel. And the ignition is just for igniting, so called four-channel burner. 2. Nozzle Nozzle made by special material, spray mouth sectional area of axial wind channel, swirling wind channel and gas wind channel are adjustable, so that can adjust the spray speed of each channel. The nozzle is the key part to ensure flame shape. 3.Ignition Device Located in the central wind channel, used for automatic igniting. 4.Metal Corrugated Compensator Which is the key part to connect each channel, sealing and adjust flame shape, and allowed process axial movement with connected channel.
