About grinding mill
Grinding mill is essential in various industries for reducing particle sizes and preparing materials for wider application. Luftklassificeringsmølle is one type of grinding mill. It is with excellent performance due to its unique mechanism and advantages. This article will give analysis on the characteristics of air classifier mill comparing with other grinding mills, and highlight applications in various industries.
Classification of Grinding Mills
Grinding mills can be divided into several types according to different design and mechanism:
Ball mill: by using grinding media to achieve crushing and grinding through impact.
Hammer mill: utilize high-speed rotating hammer to crush and grind materials.
Roller mill: use cylindrical rollers to compress and grind materials.
Luftklassificeringsmølle: combine mechanical grinding with air classification to classify particles with different fineness.
Comparasion of air classifier mill with ball mill, hammer mill and roller mill below:
| Feature | Luftklassificeringsmølle | Ball mill | Hammer mill | Roller mill |
| Mechanism | Impact + air classification | Impact + attrition | Impact | Compression |
| Particle size control | Excellent(adjustable) | Moderate | Limited | Moderate |
| Energy efficiency | High | Moderate | Low | Moderate |
| Material versatility | Wide range of materials | Primarily bulk materials | Corse materials | Medium to fine materials |
| Residue | Moderate | High | Low | Moderate |

Structure of air classifier mill
Grinding chamber: it is the part where the material is fed and ground.
Classifier wheel: separate particles to different fineness according to requirement for different application.
Airflow system: introduces air into the grinding chamber to carry away finer particles, with qualified particles left.
Advantages of air classifier mill
1. Precise particle size control: air classifier can make precise adjustment in particle size distribution, it is an ideal mill for applications requiring specific particle sizes.
2. Energy efficiency: air classifier mill can achieve high energy efficiency by minimizing over-grinding, while this is an insurmountable problem for traditional mills.
3. Wide application: air classifier mill can handle a wide variety of materials, including polymers, ceramics and minerals etc.
4. Reduce contamination risks: the closed-loop system minimizes exposure to external contaminants during processing.
Applications of air classifier mill
1. Food industry: it can be used for grinding spices, sugar, and other food material, these products require high particle size uniformity.
2. Pharmaceuticals: it can be used to produce fine powders for drug formulations with strict hygiene standards.
3. Chemicals and plastics: it is used for processing polymers and other chemical compounds that require specific particle sizes.
4. Minerals processing: it can also be used in production of fine mineral powders for construction and manufacturing.
Summary
Due to advantages and wide application, air classifier mill will high a broader prospect in future. It would be indispensable in deep-processing of powders.
