Feeding Size: ≤15-≤30mm
Application: powdering calcium carbonate, gypsum, non-metallic ore and coal, desulfurizing work in power plant
Raymond mill is a common cement mill of cement plant, and generally apply for production of mineral powder or coal powder, such as the fine powder processing of raw ore, gypsum, coal and other materials.
Why choose Raymond mill from AGICO?
AGICO Cement is one of leading raymond mill suppliers in China, we can offer any size of cement mill and related cement equipment.
Widely apply for fine-grinding of limestone, diabase, calcium carbonate, barite, calcite, potash feldspar, talc, marble, dolomite and other materials. R type Raymond mill can adjust the particle size at range of 80-325, and part of materials can reach 600.
Compare to ball mill, Raymond mill has advantages of cost-efficiency, low cost and less area occupied.
To increase the profits, the Raymond should be able to separate ultrafine mineral powder and expand production. So we updated Raymond mill fully. AGICO adopts advanced structure of like product home and aboard, and design and updated from the traditional Raymond mill.
Long service life
The service life of upper and lower grinding rings is more than 8000h, and service life of grinding ball is between 4000h and 6000h, whole machine has service life of 30 years and above. The Raymond mill also has more long replacement period of easily damaged parts.
To meet individual requirements of clients, AGICO provides custom solution for every processing production.
Take environmental protection into full consideration, the machine design is scientific, there will be no dust leakage, ash leakage of machine body, and the installation of dust silencer device, small noise, eliminate the stop production caused by the dust and noise.

Raymond mill parts
The Raymond mill is mainly composed of the main machine, an analyzer, a fan, a finished cyclone separator, a fine powder cyclone separator, and a duct. Among them, the main body is composed of a frame, an inlet volute, a blade, a grinding roller, a grinding ring, and a cover.
Raymond mill working principle
The grinding roller is tightly pressed on the grinding ring under the centrifugal force, and the material is sent by the blade to the middle of the grinding roller and the grinding ring, and the material is broken into powder under the action of the rolling pressure, and then under the action of the fan, the powdered material is blown up through the analysis machine, and the materials that meets the fineness requirement passes through the analysis machine, and they are separated and collected by the cyclone separator, unqualified materials return grinding chamber and continues to be ground. The exhaust air is separated by an industrial filter cloth to form a powder.
The pneumatic separation process of Raymond mill:
After the material is ground, the fan blows the wind into the main casing, blows up the powder, and sorts it through the analyzer placed above the grinding chamber. The unqualified material falls into the grinding chamber and re-grinds, until the fineness meets the specifications. Qualified materials enter the cyclone collector with the wind flow, collect it and discharge it through the powder outlet, which is the finished product. The wind flow is returned to the fan by the return air pipe at the upper end of the large cyclone collector. The air path is circulated and flows under the negative pressure. The increased air volume of the circulating air path is partially discharged through the exhaust pipe between the fan and the main engine, and enters the small cyclone collection to do the purification treatment.
