After being screened, the qualified portion of the limestone is used as raw material and loaded into the stone hoisting bucket along with coal in proportion, controlled by the metering system. Then, the hoisting bucket is pulled by the winch and lifted to the kiln top by the inclined bridge to the distributor, which evenly distributes the material inside the kiln. 1. The distribution device uses a "uniform distributor," which ensures that large materials are distributed in the center of the kiln and smaller pieces at the edges. 2. The discharge device uses a "discharging rotary plate," characterized by uniform discharge along the kiln cross-section. 3. The control system adopts an advanced Siemens PLC fully automatic control system, and all motors are operated using frequency converters. 4. The dust removal design is scientific and energy-efficient.
