Air classifier mill design includes a mechanical impact mill along with a dynamic air classifier. Air classifier manufacturers claim right that their products are ideal for bulk continuous processing. The machine is widely accepted and used for reducing dry fine chemicals, food items, and other materials.
Size reduction equipment for dry bulk materials processing can be availed in distinct designs. Each of the designs is made for production of coarse, fine, medium, or ultrafine particles.
A mill applies impact grinding and air classification simultaneously. The mill takes help of airflow to convey feed material to the grinding chamber of the mill, classifies the material into fine and coarse fractions, re-circulates the coarse particles for fine grinding, and pass on the fine particles out of the mill. This process is continuous.
Major components that complete the design of air classifier mill-
The mill includes a round vertical housing that encloses an internal classifier wheel that has multiple closely spaced vanes and an impact rotor mounted horizontally. Impact tools, i.e. hammers are mounted across the edge of a rotor disc placed below the wheel of classifier.
Ring shaped liner surrounds the rotor disc and hammers. The mill housing, impact rotor, and shroud and baffle assembly equipments together develop a grinding chamber. Manufacturers fit a feed material inlet at one side of the chamber, an air inlet below the rotor disc, and a combined product-and-air outlet at the classifier wheel from where discharge comes.
Is it hard to maintain air classifier equipment?
No, no machine is hard to maintain if you look at their condition well. There are certain things to look to better determine any issue later.
- Proper venting
You must check the fine side of the classifier and see if it is properly vented. Make sure dust doesn’t block its way. In quarry applications, you can eliminate venting, since dusting can be regulated with fine water mist.
- Feed rate
Make sure the feed rate is not overrated. It is critical to maintain relative consistency in the feed rate.
- Excessive water
Check for internal areas of the classifier and find if any component is damaged or worn out. If you find any hole, patch it with steel.
Excessive vibration can affect the structural integrity of the classifier.
These little things including lubrication, belt tension, gear unit backlash, and bearing temperature should be thoroughly checked and maintained for better operation of the air classifier.
