planet Ball mill Introduction and Application

In the pharmaceutical industry, the grinding and mixing of medicinal materials is essential, and the grinding and mixing of materials are essential. One vertical, with a corundum ball mill pot and zirconia grinding balls for herbal grinding and mixing. Planetary ball mill can grind the data from different industries, high-performance grinding is essential, but using as grinding container is the key to its popularity. Planetary ball mill can be installed with 4 ball mills, which is not only easy to replace, but also can be assembled with ball mill tanks with different data, such as stainless steel ball mill tank, zirconia ball mill tank, agate ball mill tank, corundum ball mill tank, etc. When the planetary mill needs vacuum grinding or atmosphere protection grinding, it only needs to assemble the vacuum ball milling groove, which is far better than other similar equipment in cost and efficiency. One vertical planetary ball mill, four 1L planetary ball mills and four stainless steel ball mills were purchased. Planetary ball mill is mainly used for research and development of grinding and mixing Laboratory of materials. After high-energy ball milling of planetary ball mill, the data will become micron or nano-sized ultrafine powder, the addition of surface area will greatly increase the activity of data, and physical and chemical reactions will have different effects.

At the same time, the homogenization of all kinds of data in the process of ball milling is also an important process of experimental research. Through continuous development and innovation, the products are not only sold well in China, but also spread over more than 90 countries and regions around the world. It is a domestic star mill brand.

Precautions for operation of planetary ball mill in hot weather?

When using in hot weather, we should pay attention to the following four points. 1. Generally, the four components (tank + ball + sample + auxiliary material) should be basically common, so as to keep the work stable, reduce the noise caused by vibration, and extend the service life of the equipment. In case of lack of samples, symmetrical application (only two cans) is acceptable. The large volume of the loading Zui is two-thirds of the volume of the ball mill pot, and the remaining one-third is used as the working space. 2. When the grinding medium overflows the grinding tank tank, it is clarified that the operating speed is too high, so the speed should be reduced. If the speed is high, the power may not be high. When the operation is started, the speed can be higher; after a period of time, the speed can be reduced a little, so that the ball milling power is higher. 3. When the planetary ball mill works normally, it suddenly appears abnormal sound. Shut down immediately, check whether the ball mill is loose, and restart the ball mill after tightening the bolts. If metal friction sound or peculiar smell is found during normal operation, immediately shut down and pull out the power line, and use hand to pull the horse sleeve. If the shaft is found to be loose, it is the bearing wear, and the bearing needs to be replaced. The machine should not be exposed to sunlight. 4. As for the planetary mill, if it is used normally, it can reach a relatively long period of time, generally more than 10 years. Therefore, we need not worry about the short service time of planetary mill.

Several answers to the application of planetary ball mill

More and more widely used, product related problems also have many people have doubts. Now, changdeli Equipment Co., Ltd. answers several common questions for us. Since the development of small and medium-sized ball mill equipment, it has become an important part of the high-efficiency ball mill equipment. Planetary ball mill is designed to destroy, grind, disperse metal, nonmetal, organic, Chinese herbal medicine and other powders. It is especially suitable for laboratory research and application. Its working principle is to use abrasive and test materials to roll in the grinding tank at high speed, and shear, impact and roll the materials to achieve the intention of destroying, grinding, dispersing and emulsifying materials. For the planetary mill, there are countless materials to grind each time, and the characteristics of the materials are also various. Different materials lead to different grinding results. Therefore, due to the different materials, we should control the grinding particle size of Xingxing planetary mill at any time. How to control it? For planetary mill, the grinding particle size is generally changed from Ball milling time and speed of two aspects. Due to the variety of materials, it is not to say that the higher the rotation speed of the planetary mill is, the better the grinding time will be. The better rotation speed and grinding time should be controlled according to the characteristics of the material itself.

In addition, the type of grinding ball, size, ball loading rate, ball to material ratio are all factors that affect the grinding particle size of planetary mill. Planetary ball mill, in theory, is a few liters of machine, mainly refers to how large the pot can be. And a machine Zui needs less than two cans to ensure the working balance of the machine. For example, let's take a 4-liter planetary ball mill as an example, that is, we can put four 1-liter cans. Available specifications: 50ml ~ 1L, 50ml ~ 500ml vacuum ball mill pot. At the same time, because there are grinding balls in the jar, the size of grinding balls is 1 / 3, that is to say, each can hold 1 / 3 of the material. The remaining 1 / 3 is the working space, so when selecting machines, if you need to produce 4 L of material at a time, you need to select a machine with a relatively large size.

Why does planetary ball mill choose planetary gear train?

Due to its high performance, high efficiency and easy to use, it is loved by users of powder mechanical grinding. Compared with the previous ball mill equipment, it has a higher useful speed, more intelligent control method, of course, the structure is also more chaotic. In particular, the planetary gear train, which is the primary operating component, has a serious impact on its life span, stability and maintenance. Planetary gear train of planetary ball mill is mainly divided into belt planetary gear train and gear planetary gear train. As shown in the figure below, the belt planetary gear train is driven by belt between the main shaft and the four planetary shafts, while the gear planetary gear train is added with transmission gears in addition to the main shaft gear and planetary gear. Compared with the gear transmission and belt transmission of planetary ball mill, the belt transmission structure is simple, no noise, and has certain buffer and vibration absorption effect; while the gear transmission is more stable and accurate, the power and speed transmitted is larger, and the service life and efficiency are better. Although the two planetary gear trains have their own advantages, with the popularization and application of planetary mills, in order to get used to the requirements of higher energy and efficiency, planetary gear trains naturally have more advantages. Therefore, planetary ball mills on the market are basically gear planetary gear trains.
