Advanced Laboratory Grinder Equipment for Efficient Sample Preparation

Planetary Ball Mill
Vertical planetary ball mill is a necessary device of high-tech materials mixing, fine grinding, sample making, new product development and small batch production. Planetary ball mill owns small volume, high efficiency, low noise and functional features which is a ideal equipment for R&D institution, university, enterprises laboratory to get samples (each experiment can get four samples at the same time). It gets powder samples under the vacuum state when equipped with vacuum ball mill tank.
Planetary ball milling machine has four ball grinding tanks installed on one turnplate. When the turnplate rotates, the tank axis makes planetary movements and the balls in the tanks grinds and mixes samples in high speed movement. The product can smash and blend various products of different materials and granularity with dry or wet methods. Minimum granularity of grinded products can be as small as 0.1 micron (i.e. 1.0×10-4mm).
It is widely used in the fields of Geology, Mining, Metallurgy, Electronics, Construction Material, Ceramics, Chemical Engineering, Light Industry Medicine, Environmental Protection etc..

Choice of Grinding Jars & Grinding Balls
In order to prevent excessive abrasion, the hardness of the grinding jars used and of the grinding balls must be higher than that of the material used. Normally, grinding jars and grinding balls of the same material should be chosen. However, the size of grinding jars and grinding balls should be determined experimentally if necessary.
Stainless steel balls, zirconia balls, alumina balls, PU balls, steel carbon balls, tungsten balls, agate balls, hard metal balls, silicon nitride balls, high wear resistant steel ball, manganese steel balls, cemented carbide, crystal glass and other special metal materials.

Product Construction & Working Principle
Inner Structure
KINGDA planetary ball mills feature dust-resistant cast iron construction with a one-piece casting molding process for the main disk, significantly extending equipment lifespan compared to conventional splicing methods.
Working Principle
The planetary ball mill operates similarly to planetary motion in the solar system. Four or two ball mills positioned eccentrically on a turntable perform simultaneous rotation and revolution (1:2 ratio). This motion generates strong Coriolis forces, creating intense impact and friction that efficiently grind samples to powder as fine as 0.1μm.
Additional FAQs
Q: What's your smallest lab model?
A: Our 0.2L planetary ball mill (Model XQM-0.4A) measures 42*30*26cm and weighs 20kg, with larger models available up to 100L capacity.
Q: What maintenance does the equipment require?
A: We use specialized wear-resistant gears for reduced noise without oil seal leakage risks. Models above XQM-20 use oil seals with proper maintenance protocols.
