Raymond mill are replacing ball mills to process graphite powder

In the past, because of the large investment in mining machinery and equipment and domestic crushing machinery technology, so the processing of mineral products is mostly a strength of large enterprises in doing.However, with the development of China's economic level, the opening of the policy and the improvement of China's mining machinery technology level, there are more and more kinds of crushing equipment in China, so that many ordinary people can invest in the field of mineral processing.Raymond machine is one of the small area, small investment, low energy crushing machinery equipment.

Although the raymond machine was invented in the United States, the technology was introduced in the 1950s.With the efforts of researchers in mining machinery enterprises in China, more and more materials can be ground by Raymond machine.From the early 2R, 3R small Raymond machine specifications, gradually developed a growing output of 4R, 5R, 6R and even 10R large Raymond machine.Ramon machine technology and specifications are far beyond other countries.The 10R raymond mill HD-2500 ultra large raymond mill from GuiLin Hangda Mining Machinery Co.,LTD. is currently the * large raymond in Asia with a ring diameter of 2.5 meters.

Take graphite grinding as an example.For a long time, ball mill has been a common grinding machine for grinding graphite powder.As a result of the ball mill has a lot of inconvenience, such as the ball mill occupies a large area (the ball mill is transverse in space), energy consumption, noise, powder fineness is not good control, maintenance is not convenient.

With the widespread use of the raymond machine, graphite powder manufacturers began to know that the raymond machine can just make up for the ball mill a few shortcomings: 

1.The ramond mill is longitudinal in space and occupies a smaller area than the ball mill

2. The Raymond mill controls the particle size of the finished powder by the grader. The fineness of the finished powder can be determined by adjusting the rotating speed of the impeller of the grader.

3, the ball mill pulverizes the material by the impact of the steel balls in the barrel to smash the material, so the noise is very big, the energy consumption is also high.

Because of the different grinding principle, the noise of the raymond mill is smaller than that of the ball mill, and the energy consumption is also lower than that of the ball mill.

4, the structure of the raymond mill is more compact, maintenance than the ball mill is more simple.

So now more and more graphite powder manufacturers choose to use the Raymond machine to process spherical graphite, the production of spherical graphite powder can be used in high-end batteries, the powder price is very high.Not only in the field of non-metallic mineral powder grinding, in some of the metal mineral powder grinding industry are with Raymond mill grinding metal ores in price, such as grinding of lead-zinc mine, due to the technology, used the ball mill grinding need to add water to the ball mill, grinding after also need to deal with waste water, has a high requirement to environmental protection, processing is bad to can cause damage to the environment, now switch to Raymond machines for dry grinding is no waste water pollution problems, so Raymond mill instead of ball mill is becoming a trend.
