1. Good product quality and high output.

2. Stable production operation, full negative pressure production, smooth air flow and high safety.

3. The rotary kiln has a simple structure and strong controllability, which is conducive to operation and maintenance.

4. Low heat consumption per unit product. Rotary kilns equipped with vertical preheaters at the end of the kiln can make full use of exhaust gas to preheat limestone and greatly reduce fuel consumption.

5. The kiln head adopts the integrated design and construction of the vertical cooler and the kiln head cover, which occupies a small area and has good airtightness, effectively avoiding the unorganized discharge of hot exhaust gas.

6. Environmental protection is good for dust collection. Pulse bag filter and cyclone dust collector are used to remove dust, and the emission concentration is less than 30mg/Nm³.

7. The level of automation is high, and the adjustment and control of the production system operation adopts PLC to centrally control in the main control room. There are few on-site operators and high labor efficiency.
