1.Raw material storage and transport.

Clean limestone with 20-40mm size was fed into the raw material tank on the top of the pre

Limestone calcination

Limestone calcination system is composed of vertical preheater, rotary kiln and vertical cooler

The preheater is the multi-bin structure,the raw material was feed into preheating tank of the preheater itself from the silo on the top of the preheater via raw material discharge chute,the higher temperature from the tail of the rotary kiln feed into preheater, then the limestone will undergo precalcining inside the preheating tank.

Limestone enter the tail of rotary kiln. Under the rotate and incline function, the limestone flow from the rotary kiln tail to the rotary head,after calcination inside the rotary kiln then become the active lime.

The lime after higher temperature calcination inside the rotary kiln then discharge into verticl cooler via rotary head.

Finished product transport

The finished lime after discharged by the cooler then was transported to the finished lime tank by chain type conveyor delivery via bucket elevator.

Smoke and environment protection treatment

Burning system

Automatic control system

Rotary kiln active lime production line adopt the fully automatic control system. The main production line adopt computer control, then realize the monitoring and control inside the central control room,the devices controlled by the computer control system located in the separate electric room.
