After the limestone has been screened, the qualified portion is used as raw material. It is loaded into the limestone hoist bucket along with coal according to the required proportion, controlled by the metering system. The hoist then pulls the bucket, which is lifted to the top of the kiln by an inclined bridge and evenly distributed into the kiln by the distributor. 1. The distribution device uses a "nine-point distributor," which ensures that large materials are positioned in the center of the kiln and smaller materials are distributed along the edges.2. The discharge device uses a "disc-type ash discharge machine," which ensures uniform discharge along the kiln cross-section.3. The control system utilizes an advanced Siemens PLC fully automatic control system, with all motors operated by frequency converters.4. The dust removal design is scientific and energy-efficient.
