Planetary ball mill technology

The Planetary ball mills features a very convenient operator guidance. All the relevant dada can be entered or called up via frequency converter:

Speed, grinding time, energy input, grinding direction reversal with selection of running and pause time, starting time, remaining running time, display of drive load factor, operating hours, clear text error messages, services intervals.

9 combinations of speed, grinding time and interval setting can be stored for repetitive grinding tasks.

Extreme speeds for particularly high final fineness down to the submicron range.

The grindng jars are arranged.eccentrically on the sun wheel of the planetary ball mill. the direction of movement of the sun wheel is opposite to that of the grinding jars in the ratio 1:-2 (or 1:-1.5).
The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called Coriolis forces.
The difference in speeds between the balls and grinding jars produces an interaction between frictional and impact forces, which releases high dynamic energies.
The interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill.
The TENCAN vertical planetary ball mill XQM-80 operates with a speed ratio of centrifugal mode. The centrifugal forces produced by the rotation force the sample and the grinding balls against the inner wall of the grinding jar, where size reduction takes place primarily by pressure and friction.

The working principle of the planetary ball mills is based on the relative rotational movement between the grinding jar and the sun wheel. In addition to the sun wheel diameter and speed of rotation this speed ratio is decisive for the energy input and therefore for the results of the size reduction process. The higher the speed ratio, the more energy is generated.

Overview

Vertical Production Planetary Ball Mill is a necessary device used for high-tech materials milling, fine grinding, powder mixing, nano powder making, new product development and small batch production. Tencan planetary ball mill owns advantages and features such as small volume, high efficiency, low noise and complete functions. Tencan planetary ball mill is an ideal equipment for R&D institutions, universities, enterprises’ laboratories to get fine powder samples. Tencan planetary ball mill is designed with four working positions and it makes you get four samples (maximum) at one time. you can also use this machine to get powder samples under the vacuum environment if it is equipped with vacuum ball mill jars for grinding.

Working Principle

Vertical Production Planetary Ball Mill often has four working positions which can be installed with two or four mill jars on one turntable. When the turntable rotates, the jar axis makes planetary movements at high speed, the balls and materials inside the jars are impacted strongly in high speed movement, and materials are eventually ground into fine powder. Various kinds of different materials can be ground by means of dry or wet grinding method. The smallest granularity of output powder can be reached to 0.1μm or nano scale powder.

Applications

Vertical Industrial Planetary Ball Mill is widely applied in industries such as geology, mineral, metallurgy, electronics, building materials, ceramics, chemical industry, light industry, medicine, environmental protection and so on. It is specially most suitable for production fields like electronic ceramics, structural ceramics, magnetic materials, lithium cobalt acid, lithium manganese, catalyst, phosphor, long afterglow phosphor, rare earth polishing powder and electronic glass. Powder, fuel cell, Zinc Oxide varistor, piezoelectric ceramic, nano material, wafer ceramic capacitor, MLCC, thermistor (PTC, NTC), ZnO varistor, dielectric ceramics, alumina ceramics, zirconia ceramics, phosphor, zinc oxide powder, cobalt oxide powder, Ni-Zn ferrite, Mn-Zn ferrite and etc.
