Product Overview
HGM series micro powder grinding mill is designed by our R&D department on the basis of multiple innovation and testing .it has been proved thousands of customers that our machine has outstanding features,stable quality, easy operation and maintenance.it is the ideal equipment for fine powder milling.
Product Application
HGM series micro powder grinding mill can be widely used in chemical industry, metallurgy, non-metallic ores and other industries. Especially in the non-metallic ore industry, the non-flammable, non-explosive and barite materials with Mohs hardness below six degrees can be ground by HGM series micro powder grinding mill,such as calcite、chalk、limestone、dolomite、kaolin、bentonite、talc、mica、fly ash 、etc.,totally more than 1000 kinds of materials.
Working principle
HGM series micro powder grinding mill mainly consist of main unit, classifier, powder collector, dust cleaner, blower, muffler,sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.
HGM series micro powder mill grinding mill large material steps
1. After crushed by hammer crusher, the large materials become small ones and are sent to storage hopper by elevator, and then evenly sent to the upper distribution plate of the turn plate by vibrating feeder and sloping feeding pipe.
2. When the ultrafine grinding mill is at work, the main bearing and each dial are driven by electromotor through reducer, and all the grinding rollers are rolling in the ring channels driving by dial through plunger.
3. The materials are driven to the edge of theturn plate by the centrifugal force and fall down into the grinding chambers.
4. The high-pressure air blower constantly inhales air, the airflow with crushed materials are brought to the classifier whose
5. High-speed impeller will screen the airflow: the unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector.
6. Most of the qualified powders will fall and exit from the discharging valve at the bottom; a small proportion of the fine powders, with airflow, moves to the dust cleaner. The materials from the above two lots are sent by the conveyor to get finished powders packed. In addition, filtered clean air will be emitted from muffler in the end.

Operation process of HGM series micro powder grinding mill:
1. Before opening the equipment, carefully check that all parts of the micro powder grinding mill are in perfect condition, that the lubricating oil is full, and that the connections between the equipment are working properly.
2 .The starting sequence shall be as follows: crusher, hoist, grinding mill and fan are turned on in sequence.
3. Operators should understand the impact of current changes on equipment in detail, and understand the impact of equipment changes on current, so as to have an intuitive understanding of the equipment.
4. The operator should repair and maintain the HGM series micro powder grinding mill regularly to ensure that all parts of the mill run normally.
1. The HGM series powder grinding mill is usually used in industrial, metallurgical and chemical industries. After you know the maintenance method, you should regularly maintain and maintain the super fine powder grinding mill, so as to prolong its service life. If you meet other problems in an operation, you can call us to consult us.
2. In the use of HGM series micro powder grinding mill, fixed personnel should be responsible for the supervision. The operator has a certain technical level. Train operators to understand the principle and performance of the mill prior to installation and operation process.
3. In order to make the grinding mill work normally, it is necessary to develop the equipment “maintenance and safe operation system” to ensure the long-term safe operation of the grinding mill. At the same time, there are necessary maintenance tools and grease accessories.
4. After the mill has been in use for a period of time, the wear parts such as rollers and rings should be repaired and replaced. And before and after use, carefully check whether the connecting bolt and nut plug of the roller device is a loose phenomenon, whether to add enough lubricating oil.
5. When the roller mill has been used for more than 500 hours, replace the roller and damaged parts again, and clean the rolling bearings in the roller sleeve. Lubricating oil can be added manually or using a filling gun.
