Introduction to Raymond Mill

Raymond mill is also called Raymond roller mill or Raymond grinding mill, which is one of the most widely used grinding equipment.

As one ancient grinding equipment, from its birth in 1906, Raymond mill has experienced generations of upgrading and the grinding technology has become more and more mature.

The new type of Raymond mill has a stronger grinding force with a protection device. Besides, the adjustment of the product fineness and the capacity can be finished during the Raymond mill operation.

In the beginning, Raymond grinding mill is only used as the coal grinding machine. While nowadays, the Raymond mill has been applied in all walks of life, especially in mines, chemical plants, pharmaceutical industry, refractory material factories, cement plants, etc.

Sometimes, Raymond mill can replace the ball mill, the latter of which has a higher cost. It realizes a highly efficient closed-circuit ultra-fine grinding, which ensures the final grinding effect.

Factors on Raymond Grinding Mill Capacity

There are many factors on Raymond mill, the direct ones of which are the material hardness, the material moisture, the finished product requirement, etc.

Material hardness: The harder the material is, the more difficult for the Raymond mill to grind, and the parts wearing is more severe.

Material moisture: If the material contents more water than about 6%, it is easier for the grinding chamber and the feeding system to be stuck. This will surely result in a reduction in the grinding capacity of Raymond mill.

Final product requirement: As the saying goes, soft fire makes sweet malt. When a smaller particle is required, the capacity of the Raymond roller mill is decreased accordingly.

Factors on the Grinding Effect of Raymond Roller Mill

Other factors on the grinding of Raymond mill are the shovel blades, grinding rings, and the number of grinding rollers. Fote has types of Raymond mills for sale with a different combination of main wearable parts:

3 rollers
4 rollers
5 rollers
6 rollers
other customized types…

Here we go to get close to the Raymond mill working sites to see types of Raymond mills meeting different customers' requirements.

Classic Cases

One of the most widely used grinding machines is Raymond mill. It has a lower cost than ball mill and smaller particle size than sand making machine.

Thanks to the modern technology and high-quality grinding solution, Fote Raymond roller mill is widely welcome. And it has been exported to countries and places around the world, such as India, Ghana, Indonesia, Pakistan, Vietnam, the United Arab Emirates, etc.

Benefits of Raymond Roller Mill

As mentioned above, during the over one century since the invention of Raymond roller mill, engineers have carried out many modifications according to the industrial production needs.

Therefore, Raymond grinding mill is performing better and better than before, which yields popularity among grinding plant investors.

The difference in New Raymond Roller Mill and The Traditional Type

Compared with the traditional Raymond mill, the new generation Raymond mill has absolute advantages.

1. The finished particle size of the new R-type Raymond mill can be adjusted arbitrarily within 80-325 mesh, and some materials can be ground up to 600 mesh.

2. With the improvement of advanced technology, the collecting efficiency of qualified powder is higher than the traditional Raymond mill and over-grinding is avoided;

3. Structural improvement reduces the overall energy consumption and the failure rate.

Applications of Raymond Grinding Mill

Raymond grinding mill can process over 200 kinds of non-flammable and non-explosive materials. The materials Mohs hardness is no higher than 9.3 and the humidity is less than 6% (a small floating can be handled).

If the material humidity is too high, natural drying is recommended for a small-capacity grinding line; while a small-type rotary dryer is recommended for a large-capacity grinding plant to dewater the materials.

Many kinds of materials can be processed by Raymond mill. They can be dolomite, kaolin, gangue, fly ash, bentonite, gypsum, limestone, coal, slag, mica, etc.

Examples of applied materials of Raymond roller mill

Generally speaking, the main applied areas of Raymond roller mill are as follows:

1. In the coal industry and power plant, Raymond mill can be used to prepare pulverized coal and improve its utilization efficiency;

2. In the chemical industry, refractory materials and other fields, Raymond mill can be used for production

3. In the field of cement plant, dry mortar and building materials, Raymond roller mill can process limestone, etc. for the production of concrete and other building materials.

4. In the metallurgical industry, Raymond mill can process slag, which is used for metal recovery to improve the service efficiency of metal ore.

Different types of Raymond grinding mills are needed in different materials processes.

Working Principle of Raymond Mill

Raymond mill has a compact structure. The main parts are shovel blades, grinding rings, grinding rollers, analyzer, fan and so on.

The whole process is divided into two stages, the grinding process and powder separation process. The former is completed mainly by grinding rings and grinding rollers. The latter is finished by the separator.

Grinding Process of Raymond Roller Mill

Grinding rollers hanged on a pulp frame roll around the central axis, which is driven by the gears. At the same time, these rollers rotate on their axis.

The materials are fed into the grinding chamber of the miller by feeding hopper.

Under the effect of centrifugal force, grinding rollers press the grinding rings. The materials are bladed up to the space between the rollers and the rings.

Then the grinding process is completed by the compaction between the rollers and the grinding rings.

Air Separation Process of Raymond Grinding Mill

Air from the fan blows the ground powder up and into the analyzer. Qualified powder flow into the collector, while those are not back to the grinder to have one more process.

The air goes back to the fan through the return flue up on the cyclone collector. Air goes in circulation and the extra will be blenched out into another cyclone collector where the waste air is purified.
