1. Vertical Mill for Raw Material Preparation
Raw material preparation in the cement production line uses GRMR40.41 vertical mill that developed by Chaeng. GRMR40.41 vertical mill is a kind of grinding equipment with these advantages: simple process, strong drying ability, safe and reliable operation, high grinding efficiency, low power consumption, easy maintenance and short debugging cycle, etc.
2. Clinker Burning System with Lower Energy and Heat Consumption
This cement production line adopts advanced raw preheating and precalcining system, reducing the heat consumption and energy consumption effectively in clinker calcined phase. The clinker has better performance, and is easier to grind. Exhaust gases from the preheater enters into the mill, which both saves energy and reduces environmental pollution.
3. Efficient Cement Mill Producing High Quality Cement
The specific surface of cement produced by cement ball mill φ4.2×13m is 3300-3800 cm²/g, which meets even beyond the common standard. In the process of using, the cement has the advantage of quick hydration reaction and fast strength development.
4. Good Pollution Control, Greening of Factory.
The 3000t/d cement production line fully considers waste and dust treatment in the design process. We install bag filter and electrical deduster in the main stage of dust treatment, reducing the dust in the air effectively. The whole factory area is fully greening, bringing a good working condition.
