The active lime rotary kiln is the main equipment for calcining lime, which is consists of cylinder body, supporting device, hydraulic wheel support device, transmission device, lubrication device, kiln seal device and other components. It has the advantages of simple structure, reliable operation and convenient production process, etc.
When the active lime rotary kiln is in normal operation, the main drive motor is driven by the main reducer to the open gear device to drive the rotary kiln. Material from the kiln (the high end of the cylinder) into the kiln to be calcined. Due to the inclination of the cylinder and the slow rotation, the material rolls both in the circumferential direction and in the axial direction (from the high end to the low end). The clinker is cooled by the kiln hood into the cooler. Fuel from the kiln into the kiln, the combustion of waste gas and material exchange, the kiln exports.
Active lime rotary kiln technical characteristics:
1, active lime rotary kiln has advanced structure, low pressure loss of the vertical preheater can effectively improve the preheating effect, the preheated limestone into the kiln decomposition rate of up to 20-25%, and can be directly used 10-15mm fine particles Grade limestone.
2, active lime rotary kiln reliable ends the combination scale seal, so that the air leakage coefficient of less than 10% use of composite refractories to reduce the loss of radiant heat.
3, active lime rotary kiln filled, can be divided into a circular or square vertical cooler, the cooler to make the lime temperature of 800C + ambient temperature, easy to transport, storage, and into the kiln secondary air preheated to 8000C or more, reducing the moving parts and special materials.
