1. Explanation and Principle
Planetary Ball Mill is designed for mixing, fine grinding, and preparing small volume high-tech material production, which features small volume, high efficiency, low noise and Lock clamps. If choosing with an optional vacuum jar, it can grind samples under the vacuum condition or filled with inert gas. The product is extensively used in the fields of Geology, Mining, Metallurgy, Electronics, Construction Material, Ceramics, Chemical Engineering, Light Industry, Medicine, and Environmental Protection, etc.
Working Principle:
When the plate rotates, the tank axis makes the planetary rotation in opposite directions and the balls in the tanks grind and mix samples in high-speed movement. The product can smash and blend various products of different materials.
It has 3 types of mill methods: dry mill; wet mill; vacuum mill.
Two or four grinding jars can work together.
(Note: granularity of grand products is dependent on the material properties, size, and quantity of milling media and processing time. According to the customer's feedback, minimum granularity can be as small as 0.1 um).

2. Application Field
The product is extensively applied in the fields of Geology, Mining, Metallurgy, Electronics, Construction Material, Ceramics, Chemical Engineering, Light Industry Medicine, Environmental Protection etc.
It's widely used in research institutes, universities, enterprise laboratories and small batch producing manufacturer.

Selection of size of planetary ball mill:
According to the number of materials to be ground, choose the size of the planetary mill.
The calculation formula for size selection of planetary ball mill: a = C /ρ* 3.
Note: A is the size of the planetary mill (unit: l), C is the mass of primary grinding material (unit: kg), ρis the bulk density of grinding material (unit: kg /L).
For example, if 2kg of material is ground at one time and the bulk density of the material is 1.5kg/L, the size of the planetary mill in row a = 2/ 1.5*3 = 4L is selected.
Reference table for selection of planetary ball mill style and special function configuration
Model selection of planetary ball mill | Nature of abrasive material |
Vertical planetary mill | Grinding of general materials, no special requirements |
Comprehensive planetary mill or horizontal planetary mill | The material is easy to sink and bind |
Double planetary mill | Ultra high speed and ultra-fine grinding are required |
With air cooling device or liquid nitrogen device | The grinding process is hot and needs to be cooled |
Equipped with vacuum ball milling tank | Easy to oxidize, requiring vacuum environment or atmosphere protection |
With heating device | High temperature grinding required |
Planetary ball mill style and special function configuration options:
Planetary ball mill is divided into vertical, horizontal, comprehensive, double planet four styles, according to the material grinding requirements, choose the corresponding styles, each style of products can be equipped with air cooling or heating equipment according to the grinding material temperature requirements.
