2L Lab Planetary Ball Mill  1 Planetary ball mill is necessary equipment for mixing, fine grinding, sample preparing, nano-materials dispersing, new product developing and preparing small volume high-tech material production. 2 the Planetary ball mill is small, full-featured, high efficiency and low noise which is the ideal equipment for scientific research units, institutions of higher learning, corporate laboratories to obtain micro particle research samples. (Four samples for each experiment). 3 It can be equipped with vacuum ball mill; the sample can be ground under vacuum. It is widely used in geology, mining, metallurgy, electronics, building materials, ceramics, chemicals, light industry, medicine, beauty, environmental protection and other departments. 4 It can set the speed, forward and reverse rotation time, and the total grinding time according to process requirement. 5 the small volume can be worked in glove box.
