Ring roller grinding mill also be called ultra fine powder grinding mill, whcih can be used in more than 300 kinds of mineral 300-2500 mesh powder making, such as: dolomite, limestone, kaolin, mica, calcium carbonate, gypsum and so on. Our ring roller grinding mill was modeled by "HGM", what's HGM meaning? That’s because there are many grinding rings and rollers inside our powder grinding mill, through the continue grinding, the little size stone lumps become the tiny stone powder, So the Clirik grinding mill also be called “Huan Gun Mo” in Chinese pronunciation, so it’s called HGM model. And “Huan Gun Mo” has the same meaning with ring and rollers.
HGM Ring Roller Grinding Mill Advantages
1.Low Operation Cost.
⑴ High efficiency: roller compacted materials directly onto the grinding disc, so power consumption is low. Compared with ball mill, it saves energy consumption by 30% ~ 40%.
⑵ Less wear and tear: As the roller is not in direct contact with the disc, and material of the roller and liner is high quality, so life lime is long.
2.High Drying Ability.
As the hot air inside contacts directly with the material, drying ability is higher, and it saves energy. By regulating the air temperature, it can meet requirements with different humidity.
3.Simple and reliable operation.
⑴ It is equipped with automatic control systems, so remote control makes it easy to operate.
⑵ It is equipped with one device,which prevents the roller from contacting with the liner directly, and avoids the destructive impact and severe vibration.
4.The stability of product quality.
As the material stays in the ring roller grinding mill for a short time, it is easy to detect and control the product particle size and chemical composition, to reduce duplication of milling, stable product quality.
HGM Ring Roller Grinding Mill Working Principle
The ring roller grinding mill
adopts the principle of impact, extrusion and grinding to crush the material, and a large clearance between the grinding ring and the pin shaft is arranged on the grinding ring bracket. when the material passes through the clearance between the grinding ring and the grinding ring, the material is impacted, extruded, grind and crushed by the grinding ring. The crushed materials under the action of gravity to the feed tray and thrown into the room grading classification by air, qualified fine powder by grading round into the collection system, coarse material is thrown to the split ring wall, back into the crushing chamber for re-grinding.When the double layer grinding machine works, the material is broken again by the gap between the second layers of grinding ring.
