What is a Raymond mill and why choose Fote Raymond mill?

Raymond mill, also known as R-type Raymond mill, is a new efficient grinding machine using the closed-cycle method. It is widely used to grind all kinds of non-metallic ores.

Fote Heavy Machinery, as one of the leading manufacturers of grinding equipment for more than 40 years produces and sales many kinds of Raymond mills and components for a variety of in dustries including cement, conceret, mineral aggregates and power generation all over the world.

Our Raymond grinding mills and related components can be inspected in our 35 thousand-square-foot facility located in Zhengzhou, Henan Province, China. Our equipment is finished and ready to ship whether you are expanding capacity or in an unexpected emergency situation.

Besides, compared to other manufacturers, Fote can provide the lowest price due to direct sale to our customers without distributor.

Raymond mill structure and working principle

Raymond mill is mainly composed of main engine, an analyzer, a draught fan, a finished product cyclone separator, a fine powder cyclone separator and an air hose.

The main body consists of a frame, an air inlet volute, a shovel, a grinding roller, a grinding ring, and a shell.

The jaw crusher crushes large pieces of material into smaller particles within the feed size of the Raymond roller mill. The discharging materials, after passing through the bucket elevator, are sent into the storage hopper and vibrating screen for being evenly and continuously ground in the main crushing chamber.

raymond mill working principle

Raymond mill inside structures

Grinding roll is tightly attached on the grinding ring under the centrifugal force, and the materials are scooped up by the relieving tool to the middle of the grinding roller and grinding ring and made into powder by the ground pressure, then the power is blown by the introduced draught fan to the analytical engine.

茄子视频APP The airflow of the fan takes away the finished product for further grade-classifying according to the set requirements.

The materials that met fineness standard can pass through it and those which are below the standard will return to the grinding cavity and be continuously ground. The finished materials are separated and collected by the sorting machine.

Raymond mill working principle

What is Raymond mill used for?

茄子视频APP R-type Raymond mill is used for the highly fine powder processing of 280 kinds of non-flammable and non-explosive materials in mine, chemical industry and building materials and other industries.

茄子视频APP And the Mohs scale of the materials should be lower than 9.3 and the humidity should below 6%, such as barite, calcite, potassium feldspar, talcum, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass and insulation materials, etc.

The particle size of the finished product can be adjusted from 80-325 mesh at random, and some materials can be reached up to 800 mesh.

茄子视频APP Raymond mill applications

Raymond mill's outstanding advantages

Small footprint

茄子视频APP Raymond mill uses the design of the vertical structure with less occupied-place and a systematic working style. The whole process from coarse crushing, transportation, grinding to final packaging is an independent production system.

High pass rate

The final powder fitness is even with a 99% pass rate, which can’t be realized by other grinding equipment.

Reliable operation

The transmission device adopts a sealed gearbox and belt wheel design with smooth transmission and reliable operation.

Better wear resistance

The important parts of Raymond mill are made of high-quality steel, the wearing parts are made of high-performance wear-resistant materials, and the complete machine is of better wear-resistance.

Automatic control

茄子视频APP The electrical system adopts centralized control, and the grinding workshop can basically achieve unmanned efforts.

Low dust pollution and low noise

Because of the improvement of working principle, Raymond mill has lower noise and less pollution.

Uniform feeding

With the electric-magnetic vibrating feeder to convey the materials, the Raymond mill has the features of even feeding, small size, low weight, fuel and power saving, easy adjustment.

What are the similarities and differences between Raymond mill and ball mill?

For the mineral processing, the most common grinding machines are Raymond mill and ball mill. So, what are the similarities and differences between the two?

Similarities

  • They are both the main equipment for grinding powder.
  • Both can be used for dry processing.
  • Both can be used for grinding non-metallic minerals.

Differences

the differences between raymond mill and ball mill

茄子视频APP The differences between Raymond and ball mill

Processing different materials

茄子视频APP Raymond mill is suitable for processing non-metallic materials that are not too hard, such as limestone, gypsum, calcium carbonate; ball mills can process metal materials and hard materials such as potassium feldspar, quartz, metal ores, etc.

Processing method

茄子视频APP Raymond mill can only be used for dry grinding, which has a requirement of the material on the humidity; the ball mill can be used for wet grinding, so there is no limit to the materials on the humidity.

Different Output

茄子视频APP The maximum output of Raymond mill is only 20-30 tons per hour, while the output of ball mill is between 0.65 tons and 615 tons per hour.

Discharging granularity

茄子视频APP Raymond mill has a uniform particle size and does not need other equipment for screening; ball mill has an uneven discharge, so the finished powder needs to be sieved by powder separator.

Grinding fineness

Raymond mill can process a finer powder and produce even product with the fineness 800 mesh while the ball mill can only reach 400 mesh.

Much noise produced

茄子视频APP The noise of Raymond mill is much lower than that of the ball mill.

Matters need attention when using a Raymond mill

correct ways to maintain raymond mill

茄子视频APP 4 points to notice when using a Raymond mill

  1. 1 During the working process, Raymond mill should be supervised by professionals, and the operators should be trained systematically before production operations. And Raymond mill should work under its maximum load in grinding.
  2. 2 According to the feeding characteristics, adjust the discharge control of the machine to meet the production requirements before starting the machine.
  3. 3 Timely maintenance. The machine should be inspected and maintained regularly to ensure that all parts of the machine work normally.
  4. 4 If the machine makes abnormal noise while working or the load of the machine suddenly increases, stop and check immediately to eliminate the fault to avoid the secondary damage. Before turning on the machine again, the residual material inside the mill must be taken out to avoid excessive current affecting startup.
  5. 5 Shutdown sequentially. When the grinding is finished, stop feeding and let the main engine continue to run firstly. Next, stop the host engine and the analyzer motor after the material in the host is completely discharged. Finally, stop the fan after the fan blows away the powder remaining in the host.

Customer case-Raymond mill processing gypsum in India

茄子视频APP Raymond mill is often used to grind a variety of non-metallic ores into superfine powders, especially for processing gypsum.

India is a country with abundant gypsum resources, India is important to the gypsum reserves and production. Many Indian customers found us and requested us for grinding production projects, especially for grinding gypsum powder.

茄子视频APP The project of the specific gypsum production line:

raymond mill grinding gypsum in India

Raymond mill production line
