The working principle of the HGM Stone Mill Grinder is based on a combination of mechanical force and airflow dynamics.
The process begins with the large materials being crushed by a hammer crusher or jaw crusher and then transported to the storage hopper via a bucket elevator.
The materials are then evenly fed to the upper distribution plate of the turnplate by a vibrating feeder and a sloping feeding pipe.
When the grinding mill is in operation, the grinding rollers roll inside the grinding rings, applying significant pressure and grinding action to the materials.
The materials are driven to the edge of the turnplate by centrifugal force and fall into the grinding chambers, where they are repeatedly pressed, crushed, and ground by the rollers.
The high-pressure air blower continuously inhales air within the grinding mill, and the airflow carries the crushed materials to the classifier.
The classifier’s high-speed impeller screens the airflow: materials with unqualified particle sizes fall back into the mill for regrinding, while the qualified fine powders mixed with air move into the cyclone powder collector.
Most of the qualified powders exit through the discharge valve at the bottom, while a small portion of the fine powders moves to the dust cleaner, where they cling to the surface of the filter bags.
The fine powders are then dislodged by the sudden vibration of the filter bags, caused by the instant ejection of high-pressure gas controlled by a pulse valve.
Finally, the filtered clean air is emitted from the muffler’s air outlet.
The HGM Stone Mill Grinder finds extensive applications across various industries due to its ability to produce fine and superfine powders from a wide range of materials. Some of the key application areas include:
