Precision Coal Weighing & Batching Machine for Lime Kilns

Coal Weighing and Batching Machine
Primarily used for precise weighing of coal fuel and proportional mixing with other raw materials to ensure accurate fuel ratio during calcination. It serves as a key equipment for achieving efficient combustion, reducing energy consumption, and minimizing pollutant emissions, directly impacting the stability of lime calcination, product quality, and environmental performance.

Working Principles:

1. Feeding Stage:
   • Coal is transported into the weighing bin via a conveyor belt or vibrating feeder.
   • Weighing sensors measure the coal weight in real time and transmit data to the control system.
2. Precision Weighing:
   • Utilizes high-precision weighing sensors for real-time monitoring, with an error margin controlled within ±0.5%.
   • Supports continuous multi-batch weighing to ensure uninterrupted and stable fuel supply.
3. Ratio Calculation:
   • The control system calculates the required addition of other materials (e.g., coal-to-limestone ratio) based on preset fuel-to-raw-material ratios.
4. Mixing and Conveying:
   • Weighed coal is mixed with other raw materials using a mixer or conveyor belt.
   • The homogenized mixture is evenly fed into the calcination zone of the vertical kiln, ensuring complete combustion and uniform heat distribution.
5. Closed-Loop Feedback:
   • Kiln sensors monitor combustion parameters (e.g., CO concentration, temperature) and feed data back to the control system for real-time ratio adjustments.
