Henan Kefan Mining Machinery Co,.Ltd products

Feature of Alumina Rotary Kiln: 1. Support device of rotary kiln: Advanced shaft structure, automatic temperature measuring device and electrical heating device. 2. Catch wheel of rotary kiln: Including mechanical wheel and hydraulic pressure. 3. Gears of rotary kiln: Single or double. The rotating speed is controlled by regulating motor, DC motor or variable frequency and speed regulation motor. Be reliable, energy-saving and efficient. 4. Cylinder  bolster of rotary kiln: Lower bolster has three types: Fixed, zoom and floating. The structure is simple and replacement is convenient it won`t hurt cylinder when it need change. 5. Sealing equipment of rotary kiln: There are many kinds for choice according to kiln models, including air cylinder edge sealing, spring edge sealing, graphite block sealing and combination for above. The feature is adaptive for cylinder rotating and swing. Sealing effect is very good. 6. Rotary Kiln head hood: Including stationery type and flexible type.

Cement rotary kiln is the main equipment for dry and wet production of cement clinker.Rotary kilns are widely used in metallurgy, chemical industry, construction, refractories, and environmental protection industries. The rotary kiln firing system is equipment with technological innovation.This system adopts the domestic advanced technology,such as the most advanced hydraulic block wheel device, a high measurement accuracy of measurement piston pump, high-precision control valve and contact-type graphite block sealing device.

The lime preheater is one host device of the active lime production, and its main function is to sent limestone from the upper part to the body of preheater, while using high-temperature exhaust gas (850°C) discharged from the calcinations kiln to make heat exchange, and the preheat the materials evenly into 800°C in the preheater. After preheating ,there is 30% CaCO3 will decompose and then pushed into rotary kiln for burning by the hydraulic push rod .So such a calcinations process not only shorten the time of limestone burning in the kiln, but also get a high degree of the active lime. Our company adopts LDO vertical preheater, and compared with ordinary preheater, it reduces the loss of line gas resistance and the power of smoke ventilator greatly, it saves the energy consumption. Besides, it features easy operation, little maintenance, simple masonry and reliable performance.

Active lime rotary kiln is composed of cylinder, gears,support device, kiln liner and kiln tail sealing equipment, hood of kiln head and alkene material device etc..Active Lime rotary kiln as a heating device is a high-quality steel processed, is supported on the support device by tyer, and there is hydraulic pressure catch wheel on the first or some gear in order to control the turning of cylinder.Gearing gyrate according to process-required rotating speed by ring gear in the middle of cylinder. Because of the need of installation or maintenance, the bigger Active lime rotary kiln has auxiliary gears, which makes cylinder gyrate more slowly. To prevent cold air come in and dust overflow, the reliable kiln tail and hed sealing equipment are installed on feed and discharge end.The most common are Cement clinker Rotary kiln, etc., more models to choose.

The structure of Air Swept Coal Mill: Our factory manufactures has been improving day by day after years of practical experience and continuous improvement. After making significant improvements to traditional air-swept coal mill and possessing all features of ball mill, compared to the same specification mill other manufacturer produce, the capacity of our mill has increased greatly with discharging material more fine and increased specific surface area so as to realize high yield, high fine powder and supplying a new energy-efficient grinding equipment for users. Air Swept Coal Mill is widely used in grinding coal operation of metallurgy, cement, power, mineral processing, new materials, fertilizer and glass ceramic industry. It is a kind of special equipment which crushes and grinds coal with the function of drying simultaneously.

Broken qualified limestone enter into lime calcining system.First,limestone enter into vertical preheater to preheat, which can shorten the calcined time inthe kiln and can obtain higher degree of activity lime.Then limestone enter into rotary kiln to burning.Last,burned limestone enter into the vertical cooler to cool.
