Cement Plant Ball Mill Equipment | High Efficiency And Energy Saving

Introduction of Cement Grinding Production Line

Cement grinding is a key step in cement production, directly determining the fineness, strength, and energy efficiency of the finished product. With increasing national energy-saving and environmental protection requirements for the building materials industry, modern cement grinding production lines are developing towards high efficiency, low energy consumption, and intelligent technology.

Cement Grinding Production Line Process

1. Closed-Circuit Grinding System (Mainstream Process)

• Process: Raw material crushing → Pre-homogenization → Batching → Pre-grinding in roller press/vertical mill → Fine grinding in ball mill → Classification in classifier → Finished product storage

• Advantages: Energy consumption is reduced by 20%-30%, and the finished product fineness is adjustable (300-500 m2/kg), making it suitable for large-scale production.

2. Open-Circuit Grinding System

• Features: No powder selection step, simple process, but higher energy consumption, suitable for applications where fineness requirements are less stringent. 3. Combined Grinding System

• Technology Combination: Roller Press + Ball Mill Working Together, Increases Production Capacity by 40%, Power Consumption ≤ 30kWh/t

Process Comparison Table:

Type	Power Consumption (kWh/t)	Fineness Control	Investment Cost	Applicable Scale
Closed-Circuit System	28-32	Precision	High	Medium-Large Production Line
Open-Circuit System	35-40	General	Lower	Small/Specialty Cement
Combined System	25-30	Precision	Highest	Large Energy Saving Project

Core Equipment Analysis

1. Grinding Machine Selection

• Ball Mill: Traditional equipment with strong adaptability but high energy consumption (accounting for over 50% of the total line's power consumption).

• Vertical Roller Mill (Vertical Mill):

Energy Saving Advantage: Power consumption is 15%-20% lower than a ball mill.

Integrated Functions: Combines grinding, drying, and powder selection, making it suitable for slag/cement composite grinding.

• Roller Press: The preferred choice for pre-grinding, offering high crushing efficiency and reducing the load on the subsequent ball mill.

2. Supporting Equipment List

• Feeding Equipment: Quantitative Feeder, Belt Scale

• Classification Equipment: Cyclone Classifier, O-Sepa High-Efficiency Classifier

• Dust Removal System: Pulse Bag Dust Collector (Emission ≤ 10mg/m³)

• Automation Control: DCS Central Control System (Real-time monitoring of production, energy consumption, and other data)
