We have rich experience in helping our customers both at home and abroad building active lime production line. Our professional engineers can help customers with technical solution, equipment installation, training and other services.
Production Process Introduction
Qualified limestone stored in silos will be lifted and transferred via bucket elevator into the hopper on the top of the preheater. In the hopper, feeding quantity is controlled by the upper material level meter and the lower material level meter. Then limestones are evenly distributed through the feed tube to the preheater's chambers. Limestones are heated by 1150 ° C flue gas to 900 ° C in the preheater, about 30% limestones decomposed. They are pushed into the rotary kiln by hydraulic push rod, sintered and decomposed into CaO and CO2. After decomposition, the limestones enter the cooler where they are cooled to 100 ° C by cold air and then are discharged. After heat exchange, 600 ° C hot air goes into rotary kiln and is mixed with gas for combustion. Exhaust goes into the bag filter through the induced draft fan, and then goes into the chimney through the exhaust fan. Lime discharged from the cooler is transferred by vibration feeder, chain conveyor, bucket elevator, and belt conveyor into the finished product warehouse.
Advantages of Active Lime Production Line
1, the finished product has good quality and high activity, especially suitable for large-scale lime production.
2, the production runs stable. Because of negative pressure production, air flow is smooth, which ensures high safety.
3, rotary kiln has simple structure and is controllable, good for operation and maintenance.
4, it is capable of calcining limestone of fine fraction, making the best of mine resource.
5, bag filter is used for dust collection. Concentration of emission is less than 50mg/Nm3.
6, per unit of product's heat consumption is low. Rotary kiln equipped with vertical preheater can take advantage of exhaust gas to preheat limestone, greatly reducing fuel consumption.
7, industrial exhaust such as blast furnace exhaust, calcium carbide exhaust, semi-coke furnace exhaust can be used as fuels for lime calcination.
