PULVERIZER 80 Planetary ball mill

PULVERIZER 80 Planetary ball mill

PULVERIZER 80 planetary ball mill utilizes the principle of planetary revolution and rotation, and the grinding ball moves at high speed in the grinding bowl. Through high-energy friction and impact force, the sample is crushed, which can quickly grind the sample to 1μ Below m. PULVERIZER 80 planetary ball mill is suitable for grinding hard to soft and brittle samples in the laboratory and samples in suspension. It is an ideal choice for ultrafine powder grinding, sample processing in the pharmaceutical industry, preparation of new materials, and mechanical alloying of materials.

Working principle

The crushing and grinding of materials are mainly achieved through high-speed friction and collision between grinding balls. When the large disk rotates, the grinding tank containing sample materials and grinding balls rotates at high speed in the opposite direction around its center axis. At a certain speed, centrifugal force causes the sample and grinding ball at the bottom of the tank to separate from the inner wall of the grinding tank. The grinding ball travels at high speed inside the tank, further grinding the sample by hitting the tank wall. In addition, the impact collision between grinding balls also accelerates the consumption of sample size. The main disc of the solar wheel of the PULVERIZER 80 planetary ball mill has a rotational speed of up to 800rpm and a centrifugal force of up to 50g.
