Types of automated lime kiln production equipment
In the field of lime production, there are various types of automated lime kiln production equipment with unique features.
From the perspective of kiln structure, there are rotary kilns and vertical kilns. The rotary kiln equipment production line consists of feeders, elevators, preheaters, burners, coolers, dust removal systems, etc. The kiln body is parallel to the horizontal plane, with a slight angle, and has a large output, but the investment and land area are also relatively large. Vertical kilns are compact in structure and occupy a small area, such as beam kilns and sleeve kilns, which belong to the category of vertical kilns and are suitable for various fuels. When the production operation is normal, the lime activity can reach a high level.
In terms of batching equipment, the vibrating feeder can evenly transport limestone to the feeding system, and the bucket elevator can lift raw materials from the silo to the top of the kiln. In the air supply equipment, the fan provides the oxygen required for combustion, and the air preheater can preheat the hot air generated by calcination, improving fuel utilization efficiency.
In the ash unloading equipment, the screw conveyor uses spiral blades to rotate and transport quicklime powder, while the pneumatic conveying system uses airflow for conveying, which is suitable for situations where high conveying efficiency is required. In addition, there are dust removal and environmental protection system equipment, such as cyclone dust collectors and bag dust collectors, which can effectively treat dust in the production process and meet environmental protection requirements.
