Raymond Mill

raymond mill parts

As a major grinding manufacturer, China SBM Company has developed this new kind of suspension grinder with strong pressure on the basis of international advanced technology. And the Raymond Mill also has some relative names, such as new energy-saving Raymond Mill, pendulum Raymond Mill equipment, super thin suspension grinder, etc. And this kind of Raymond Mill can be applied to the powder manufacturing with high-pressure and closed circuit in the field of small mines, chemicals, building materials, metallurgy, etc.

Raymond Mill Application

Raymond Mill is suitable for producing minerals powder, which is widely used in the fields of metallurgy, building materials, chemical, and mining industry. It can be used to grinding the minerals and material that Moh’s hardness degree is below 7, and humidity is in 6% non-flammable explosive minerals. The final product size is adjustable as required in the range of 100-325 meshes (0.125mm-0.044mm).

Raymond Mill Working Principle

The working process of the Raymond mill is that the transmission device brings along the central axis to drive. The upper part of the axis connects with the Quincunx Rack, on the frame is loaded with the rollers, and forms a swinging pivot. It does revolve around the central rotation, at the same time it revolves around the grinding rings, and itself also rotates on account of the grinding effect. In the process of rotating of the shovel and the roller, the material will be fed into the rings and the rollers, a material layer is formed ,which is functioned by the rollers to revolve, produces the inside and outside centrifugal force (compression force) to grind the material, thus get the powder. The separator will separate the powder. The rotational speed of vane can be adjusted according to the final powder size. If users want to get finer powder, they can accelerate the vane, increase contact of the vane and the powder, therefore the unqualified powder will be thrown to the outer wall, separated from the air current. After the air current and the fine powder are separated, the powder is collected.

Raymond Mill Main Structures

The main structure of Raymond Mill are including the main machine body, analyzer, wind machine ,final products classifier ,fine powder classifier and the wind pipes. And the main unit of the Raymond Mill is including the frame, inlet shell, shovel, roller, grinding ring, and the cover.

1. The technical advantages of the Raymond Mill: developed by China Mining equipment Co., Ltd., the Raymond Mill with large, middle, small type energy-saving have adopted the modern design manners and taken the advanced crushing theory as the guidance. And the design of grinding roller is installed on the both end of the star rack central axis, which can make the grinding roller situated in a natural and balanced condition. And the main unit has been proceeding the well function with small vibration.
2. The occupation area grinding roller have covered in the cavity of the main unit is small so that the working space will become larger .And then the high-pressure wind of the blower will reach larger working area so that the fine powder have more chances to get out of the main unit and enter the cyclone collector, which can avoid the repeated grinding of the super-thin powder with no efficiency. And that’s the reason that the output of the new type Raymond Mill with energy-saving is higher than the traditional Raymond Mill with three grinding rollers.
3. The new type Raymond Mill with energy-saving only has two grinding roller with lower working load ,which can save the energy by 25% and improve the output by 20% than the traditional Raymond Mill with three grinding rollers. And the new type Raymond Mill with energy-saving adopt advanced technology and also have created the considerable economic benefits for more than eight hundred of clients.
