Main equipments in the process of lime rotary kiln

Main equipments in the process of lime rotary kiln includes vertical preheater system, transportation system, rotary kiln, combustion device and vertical cooler, pulse bag filter and other equipment, a complete set of system equipment, reliable operation, high degree of automation, good productivity and product quality. 1. Preheater For different active lime production scale, the preheater is suitable for all kinds of square production, round o polygonal vertical preheater. The hydraulic push rod is used to feed the rotary kiln, the equipment is operated reliably; the top silo is provided with a level gauge control to ensure the stable material layer height of the preheater. 2. Rotary kiln (1) Corresponds to the size and the appropriate furnace type, diameter and length; (2) Transmission speed motor driven kiln body, and is equipped with an auxiliary motor, stable operating flexibility to adjust; (3) Preheater kiln head spring-type seal structure, is simple, reliable and good sealing effect. (4) Spare diesel engine drive force. 3. Cooler (1) The cooler is divided into four zones. Each zone can be controlled individually. The cooling air and the hot material are in direct contact with each other. The cooling effect is good. The temperature is not higher than the ambient temperature of about 50 ?, the temperature of the secondary air preheated more than 600 ? (2) Cooler without moving parts, less equipment maintenance. 4. Burning equipment (1) Using coal as fuel, according to the size to choose two channels, three or four, different coal combustion apparatus the to match the type of kiln. Full combustion, lively flame, good rigidity, it does not hurt the kiln, good applicability, low maintenance costs, the key components of high temperature ceramic elements, stable and reliable performance, low investment system. (2) Natural gas combustion system consisting of gas burners, control valve groups, gas through the pipeline control valve group, into the rotary kiln burner, the main and secondary wind mixed combustion. Gas flow control flexibility. Gas burners consist of multiple hollow sleeves and helical body compositions. Natural gas burner channel vortex or DC form, more uniform combustion gas and air mixing effect is more ideal, but also can control the wind flow so that the shape of the burner flame autonomously adjusted according to production. The combustion system is also automatically cleared, emergency stop, is safe and reliable.
