YGM raymond mill is also called high pressure roller mill. It is developed upgrading products of Raymond mill with higher efficiency and capacity. It is suitable to process non-lammable and non-explosive mineral materials with Moh’s <9.3 humidity < 6%.

The Raymond mill is actually the earliest powder grinding mill equipment, and YGM series high-pressure mill is improved updated on the basis of the Raymond mill. The difference lies in the feed particle size, discharge particle size, and capacity.
1.Feed size. For original R-series Raymond mill, the smaller feed, it will be more stable output and higher processing efficiency. While the feed size of YGM raymond mill is larger than the range of Raymond mill.
2.Output particle size: the discharging particle size of Raymond mill is in the range of 30 mesh to 325 mesh, while the output particle size of YGM high pressure grinding mill is in the range of 80 mesh to 425 mesh. The finished product is finer and the screening rate is higher.
3.Capacity: Due to the strong pressure of the high-pressure spring, the output of the high-pressure grinding mill will be higher than that of Raymond mill.
4. In the process of long-term use, when the loss of the grinding roller and grinding ring is serious, even if the bolt and other parts are adjusted, it can not be tightly ground, and the finished powder can not reach the required finness. At this time, only the fragile ones can be replaced. Parts, but the high-pressure mill will not be like this. Under normal circumstances, before reaching the grinding critical point, the high-pressure device can be adjusted to make the grinding roller and the grinding ring tightly pressed to maximize the use.
The whole powder grinding process is completed in the closed air circulation system to reduce environmental pollution.
Stable Raymond mill plant is an independent milling system from primary material to final powder. It covers small area with solid structure.
Fineness of finished powder is even, and qualified screening rate could reach 99%, which is difficult to reach for other milling equipment.
The grinding unit and upside classifier are connected by spring, and sealed with soft belt, which reduce the noise and avoid sympathetic vibration to reduce the vibration of machine vastly.
YGM Raymond mill is high pressure grinding mill composed by main grinding machine, fineness analysis machine, blower, cyclone, bag dust collector and connecting air duct. According to user needs, Baichy machinery could supply jaw crusher, bucket elevator, vibrating feeder, electric control cabinet and other auxiliary equipment. How does YGM raymond mill machine work? In YGM raymond mill frame, a 1000-1500kg high pressure spring is fixed to the roller suspender. After the grinder is put into effect, the ring affected by the high pressure spring and centrifugal force. And its rolling pressure is 1.2 times higher than that of the Raymond grinder under the same power condition and the output is raised to higher degree. When materials loaded into the grinding cavity. It is shoveled into the space between the roller and the ring for grinding. The being grinded powder is routed to the classifier along the circulation wind of the blower. Qualified fine powder is guided to the cyclone collector as final product and large size powder falls back to the grinder for regrinding. There is a powder locking equipment under the cyclone in raymond vertical grinding mill , which isolates the outside positive air pressure and the negative air pressure inside cyclone. And this ensures high productivity. In addition, the residual air and dust under the main unit will be transferred to dust catcher equipment through pipes and be cleaned there. The clean air will be discharged so that environment will be protected.
