QM series planetary ball mills could grind or mix solid particles of different granularities and materials, suspension and paste with dry and wet methods. If a vacuum ball milling tank is used, it will be possible to grind and mix samples in vacuum or inert gases. Through the application of many scientific research and enterprise units, it is proved that the QM series planetary ball mills manufactured by our plant have a granularity of grinding materials fully meeting nano level, which has already reached up to about 30 nano (0.03 um) according to feedback of users. In addition, this series of ball mills is widely applied to the fields such as geology, metallurgy, soil, building materials, chemical industry, light industry, medicine, electronics, porcelain, battery and environmental protection and so on.
Along with the high-speed development of science and technologies, and the wide application of nano materials, the mechanical alloying (MA) discovered in 1980s endows QM series planetary ball mills with new missions. The basic process of mechanical alloying is that the powder and particles of several kinds of metallic and non-metallic elements are repeatedly mixed, crashed and cold welded in ball mill, gradually refined to nano level in the process of ball milling, and form a nucleus of alloy phase in solid state, which has made some substances difficult to realize alloying with traditional melting process actually materialize alloying in the process of milling, and made many units using the ball mills manufactured by our plant realize many kinds of alloy powder, such as nano crystalline hard alloy, Nd60Fe20Al10CO10 non-crystalline alloy powder, and Al2O3/Al compound powder and so on.
2.Operational PrincipleQM series planetary ball mill has four ball milling tanks on a big tray, and when this big tray circumvolve (revolution), it will drive ball milling tanks to circumvolve (rotation) surrounding its rotor axis to form epicyclic motion. The drive ratio of revolution and rotation is 1:2 (one circle of revolution will make two circles of rotation). As for the functions of epicyclic motion, the milling ball and milling materials inside the tanks impact with each other under the functions of eccentricity, and break up, grind and mix testing samples.
QM-3SP4-CL gear drive planetary is manufactured with self-lubricating reinforced engineering plastics by our plant, which ensures mechanical strength and reduces noises at the same time.This product is a patented product of our plant with a patent number of ZL022202595.
Interval operation function: To prevent the property and quality of milling materials from being affected by overheating generated by ball milling, this machine could automatically control the time of each state as per the circulating mode of "operation - shutdown - reoperation".
