Limestone resources will enter the era of scarcity, how to choose active lime calcination equipment?

Highly active, high value-added reactive limes are widely used and have broad market prospects. In recent years, the exploitation of limestone resources as active lime raw materials has been greatly tightened, and limestone resources will officially enter the era of scarcity. If the limestone resources cannot be rationally utilized, it will have a negative impact on the sustainable development of the active lime industry and the steel industry.

Calcination is a key process in the production of activated lime. The choice of calcining equipment has an important impact on the full utilization of limestone resources. General mine products 0-30mm fine-grained limestone accounts for 30-40% of the total output. If not fully utilized, limestone resources will be seriously wasted.

At present, the active lime calcination equipment is different, and the limestone grade used is also different. The rotary kiln can directly calcine 10-50mm fine-grained limestone, so that most of the limestone below 40mm can be utilized, and the annual mining cost can be saved and the mining life of the mine can be extended. Therefore, the rotary kiln calcined active lime has good advantages and good development prospects in fully utilizing the limestone resource energy.

As the governing unit of China Lime Association, Xinxiang Great Wall is committed to promoting the sustainable and healthy development of the lime industry. It always puts the technological innovation of rotary kiln equipment in the first place, vigorously develops lime rotary kiln equipment, and produces lime rotary kiln with advanced technology, energy saving and environmental protection. The quality of finished products is well received by customers.
