Compared with Hammer Mill, What Are the Advantages of ACM Mill

Air classifier mill(ACM) and hammer mill are both crushing and grinding equipment. Both them belong to the category of mill, and they are commonly used for crushing equipment in industry. But they also have many difference. Compared with hammer mill, the advantages of ACM/air classifier mill mainly reflect in the following aspects:

Below are the advantages of ACM:

1. Integrated grinding and classifying

Air classifier mill(ACM) combines grinding and classifying into one system, thereby increasing efficiency. In contrast, hammer mill has no integrated grinding and classifying system. So compared with ACM, the production efficiency of hammer mill is lower.

2. Finer particles

ACM can achieve finer and more uniform particles, even up to the nanometre level. Hammer mill can also perform fine grinding of material , but the finest particle is usually between 1-5 microns.

3. Suitable for handling heat-sensitive

Air classifier mill usually operates at low temperatures. Meanwhile, It generates only little heat during its operation, These two factors prevent heat-sensitive material from thermal decomposition or oxidation. While hammer mill utilizes high-speed impact mechanism of the hammer head, at the same time, friction of internal components occur during operation, so excessive heat is generated. This may reduce the quality of finished product of heat-sensitive material.

4. Easy to clean

ACM has a simple internal structure, and the airflow helps to remove the residual material, which reduces the difficulty of cleaning. This feature is particularly beneficial in occasions where material is frequently changed, or with strict requirements on mass production. While, hammer mill has more internal residual material, especially at the position of hammer head and the sieve. This increases the difficulty and complexity of cleaning.

Compared with hammer mill, the characteristics of air classifier mill make it suitable for more occasions, and the application prospect of air classifier mill will become boarder.
