Selection of Rotary Kiln Equipment in Active Lime Production Line

The main equipment in the active lime production line is the rotary kiln, which can be divided into cement kilns, active ash manufacturers, metallurgical kilns, alumina kilns, drying kilns and lime kilns according to different materials. The rotary kiln has simple structure, convenient and reliable production process control, few vulnerable parts, and high operation rate. It is the equipment for calcination of high-grade cement in cement plants. It is also widely used in metallurgy, chemical industry, construction and other industries. The active lime kiln produced by our factory has strong structure, stable operation, and high-quality products.

Active ash manufacturers

Active lime kiln is abbreviated as lime kiln. There are a wide range of fuels for burning lime, solid fuel, gas fuel, and liquid fuel. Those fuels that can save more energy are the key to the new technology lime kiln. Currently, coke and coal gas are commonly used. In terms of new technology, gas is the most ideal, including blast furnace gas, converter gas, coke oven gas, calcium carbide tail gas (gas) producer gas, etc., which are the best fuel for lime kilns. Because these gas fuels are waste utilization, circular economy nature. In particular, most of the coke oven gas is now released, and the resources are very rich, followed by blast furnace gas, and then calcium carbide tail gas. If these gas are used, they can save a lot of energy, and the environment can be protected. Receive very good economic benefits. If these gas-fired lime kilns are developed in large numbers, the environmental pollution problem of earth-fired kilns will naturally be solved.

　　 Cement kiln is the main equipment of cement clinker dry and wet active lime production line. Cement kilns are widely used in industries such as metallurgy, chemical industry, building refractory materials, and environmental protection. The cement kiln consists of a cylinder, a supporting device, a supporting device with retaining wheels, a transmission device, a movable kiln head, a kiln tail sealing device, a coal injection pipe device and other components. The kiln body of the cement kiln is inclined to the level. The whole kiln body is supported by the supporting roller device, and has a blocking wheel device that controls the kiln body to move up and down. In addition to the main drive, the transmission system is also set in the main power source. The auxiliary transmission device that can still make the kiln body rotate when it is broken and prevent the kiln body from bending and deformation. The kiln head and kiln end sealing device adopts advanced technology to ensure the reliability of the seal.

　　 Metallurgical kiln is commonly known as metallurgical calcining kiln, which is mainly used for the magnetization and roasting of lean iron ore in steel plants in the metallurgical industry. Metallurgical kilns can be divided into alumina kilns, zinc oxide kilns, nickel-iron kilns, etc. according to the types of metal compounds. Mainly used for roasting high metallurgical ore and aluminum factory roasting clinker and aluminum hydroxide in various metal compound refractory plants; chemical factory roasting chromium ore and chromium ore powder and other minerals.

The alumina kiln calcining system equipment has passed technological innovation. In this system, the most advanced domestic and foreign hydraulic gear wheel device is adopted, the metering plunger pump with high metering accuracy, the high-precision speed regulating valve and the contact type graphite block sealing device are adopted. Domestic advanced technology. Easy to operate and reliable to use. The thermal engineering system is stabilized and the equipment operation rate is increased. Compared with the equipment of the same specification, the operation rate is increased by 10%, the output is increased by 5%-10%, and the heat consumption is reduced by 15%.
