Cleaning Hosokawa’s ACM
The video provides a detailed description of the cleaning of the Mikro ACM® Air Classifying Mill (15 ACM model). Cleaning is required in order to take care of possible build-up on the mill’s rotor after a prior test. First, parts (including the mill itself) are removed and washed, rinsed, and scrubbed to remove foreign material.
The parts are then towel dried and sprayed with compressed air to ensure that all moisture is removed. The parts are then re-assembled for the next test. Please take heed of the caution sign on the mill: Lock Out Power Before Opening Guards, Access Doors, or Covers. Finally, a clean rag is used to double-check that no material is left in the mill.
The Mikro ACM® Air Classifying Mill is an air-swept mechanical impact mill with a dynamic air classifier designed to grind an extensive range of materials down to D97 < 20 µm.
Design and Options:
- Models for small batches and large production systems
- Narrow particle size distributions
- Pressure shock resistant models
- Special easy-to-clean designs
- Operate with heated air for flash drying
- Wear options include stainless steel, ceramic, or tungsten
- Compact and space-saving designs
- Economical and efficient milling system
- Suitable for chemical, mineral, food, and pharmaceutical materials
- Available in 15 model sizes from 1 hp up to 600 hp
Due to the Mikro ACM® Air Classifying Mill’s air-to-material ratio requirement, heat-sensitive materials can be handled without product degradation. When milling hygroscopic materials, conditioned inlet air can be used to reduce moisture in the system. In high-temperature drying applications, the bearing housing can be insulated and air purged to protect the bearings. The mill can also operate with chilled air for heat-sensitive materials to prevent build up and for more efficient grinding.
Mikro ACM® Air Classifying Mills were invented by Hosokawa in the late 1960’s and are one of the most versatile types of size reduction equipment available in the industry.
