QM-2SP12 Planetary Ball Mill is an essential dev ice for mixing, fine grinding, sample preparation, nano-materials dispersion, new product development and small batch production of high-tech materials. With small size, full-feature, high efficiency and low noise, this product is an ideal instrument for scientific research institutions, higher institutes and corporate research laboratories to obtain the micro-particle samples (four samples can be obtained in one experiment). If equipped with vacuum ball milling cans, it can grind the samples under vacuum situation. QM series planetary ball mills are widely used in geology, mining, metallurgy, electronics, building materials, ceramics, chemical industry, light industry, medicine, beauty, environmental protection and other departments.

Working Principle

A turntable is equipped with four milling cans. When the turntable rotates, the milling cans revolve both around the wheel axis and on their own axis, like planetary movement. Balls and materials in the cans collide and rub against each other during the high-speed movement so as to achieve the purpose of crushing, grinding, mixing and dispersing samples. This instrument can grind and mix samples of different sizes or materials during dry and wet conditions. The smallest particle discharged is 0.1um (namely1×10mm-4).
