50 TPD Mini Small Capacity Lime Vertical Kiln with 2022 Factory Price

Vertical kiln only uses lump coal for vertical lime kiln when coal as fuel, with the granularity being 10-30mm. And the granularity of raw limestone is 50-120mm. Through electronic weighing, coal and raw materials are mixed and fed into vertical kiln for calcination.

Lime vertical kiln is a vertical kiln for burning lime. Is an all-steel vertical cylindrical equipment. It uses the principle of material self-weight descending and hot gas rising to conduct heat exchange for lime burning.

Difference bewtween Vertical Kiln and Rotary Kiln

1.The advantage of vertical kiln is small investment, easy operation.

2.The weakness is uneven lime quality, small capacity.

3.While the natural gas is as fuel for vertical kiln, it’s calcinated equably, with good lime quality, which has not big difference with the lime quality through rotary kiln.

1.Rotary kiln, no matter what the fuel is, the lime quality is even and the activity is high.

2.It’s mainly taken for steel plant which has demand on a high activity lime product.

3.It takes automation to control calcination, less workers, big productivity and high quality.

4.There is not so high requirement on the coal, it can use lump coal and coal power both.

Flowchart Process of Lime Vertical kiln

Vertical kiln is divided into three areas from top to bottom: preheating zone, calcining zone, cooling zone according to the temperature change and distribution.

1. preheating zone: the material is preheated by the heat of the flue gas,

2. calcining zone: the material is calcined by the heat released by the combustion of the fuel,

3. cooling zone: the calcined material exchanges heat with the blown cold air, the material itself is cooled, and the air is heated and enters the calcination zone as combustion-supporting air.
