Description
Active Lime production line process: qualified limestone stone stored in the silo, from the upper and lower 2 level meter to control the amount of feeding, and then through the pipe to the limestone evenly distributed to the preheater each room.
Active Lime stone in the preheater was 1150 degrees Celsius kiln smoke heated to 900 degrees Celsius, about 30% decomposition, the hydraulic putter into the rotary kiln, limestone in the rotary kiln by roasting into CaO and CO2. After the decomposition of limestone into the cooler, in the cooler was sucked into the cold air cooled to 100 degrees Celsius below discharge. The heat exchange of 600 degrees Celsius hot air into the kiln and gas mixed fuel. Exhaust gas and then into the cold air by the fan into the bag filter, and then discharged into the chimney by the exhaust fan. The limestone discharged from the cooler is fed into the limestone reservoir by vibrating feeder, chain bucket conveyor, bucket elevator, tape conveyor. According to the user needs to determine whether the screening process.
The active lime kiln is a kind of rotary kiln which is the main equipment for calcining the active lime. The equipment consists of the cylinder body, the supporting device, the hydraulic wheel support device, the transmission device, the lubrication device and the kiln seal device. Rotary kiln has a simple structure, reliable operation, the production process to facilitate automatic control.
Advanced structure, 8000Pa low pressure loss of the vertical box preheater can effectively improve the preheating effect, the preheated limestone into the kiln decomposition rate of up to 30%, and can be directly used 10-15mm fine-grained limestone.
Reliable rotary kiln at both ends of the combination of scaly seal. So that the air leakage coefficient of less than 10%, the use of composite refractories to reduce the loss of radiant heat. Filled, can be divided into a circular or square vertical cooler, so that the cooler of the lime temperature of 80 ℃ + ambient temperature, easy to transport, storage, and can be into the kiln secondary air preheat to 700 ℃ or more, Make full use of waste heat, save energy consumption.
