Active lime with high activity and added value is widely used and has a broad market prospect.In recent years, the exploitation of limestone resources, as the raw material of active lime, has been greatly tightened. Limestone resources will officially enter the era of scarcity.How to choose the proper equipment for calcining active lime?

1. Limestone calcination equipment

Calcination is a key process in the production of active lime, the choice of calcination equipment is very important, the choice of limestone rotary kiln has an important impact on the full use of limestone resources.Generally, 0-30mm fine grain limestone accounts for 30-40% of the total output of mine products. If not fully utilized, limestone resources will be seriously wasted.

2. Calcining in rotary kiln

At present, different calcination equipment of active lime USES different limestone particle size.The rotary kiln can calcine 10-50mm fine grain limestone directly, so that most of the limestone below 40mm can be utilized, and a large amount of mining costs can be saved every year, and the mining life of the mine can be extended.Therefore, calcining active lime in rotary kiln has a good advantage and a good prospect in making full use of limestone resources and energy.

3. Rotary kiln production process
