Histórias de sucesso
Cement Producer
The grinding system produces 70 tons of cement per hour. It adopts pre-crushing and high-efficiency powder separators, and rationally installs bag dust collectors at multiple material discharge points. It has the characteristics of energy saving, environmental protection, and high production capacity.
1. Pre-Crushing for Higher Grinding Efficiency
A single-stage box-type hammer crusher is used to pre-crush clinker, limestone and other feed materials to an appropriate size, reducing the crushing load on the ball mill and improving overall energy efficiency and capacity.
2. 4.2 m Large Ball Mill | 70 t/h Capacity
The Φ4.2 m large ball mill is designed specifically for cement grinding, with a capacity of 70 t/h. The combination of pre-crushing and optimized internal liners improves grinding efficiency while reducing energy consumption.
3. High-Efficiency O-Sepa Classifier
The ball mill operates in a closed circuit with an O-Sepa high-efficiency classifier. Fine powder is separated as finished cement, while coarse particles are returned to the mill for further grinding. The product fineness can be adjusted within 280–650 m²/kg.
