Planetary Ball Mills are used wherever the highest degree of fineness is required. In addit

Planetary Ball Mills PM 100 / 100 CM / 200 / 400
Planetary Ball Mills are suitable for mixing and grinding soft, medium-hard, extremely hard, brittle and fibrous materials. They are used whenever high degrees of fineness down to the submicron range are to be achieved in a very short time. In addition to dry and wet grinding, they are also suitable for colloidal grinding and mechanical alloying. Typical materials are minerals, ores, chemicals, ceramics, soils, household and industrial waste etc.

Features:
-extremely high ultimate fineness down to submicron range
-1, 2 or 4 grinding stations
-grinding jar volumes from 12ml to 500ml
-suitable for long-term trials and continuous use
-programmable starting time
-power failure back-up ensures storage of remaining grinding time
-reproducible results due to digital parameter setting
-10 parameter combinations can be stored
-single button operation with graphic display
-automatic grinding chamber ventilation for cooling the grinding jars
-grinding jars in 7 sizes and 8 different materials available

Function Principle:
The grinding jar is 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.
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.

Planetary mills with a single grinding station require a counterweight for balancing purposes. In the Ball Mill PM 100 this counterweight can be adjusted on an inclined guide rail. In this way the different heights of the centres of gravity of differently-sized grinding jars can be compensated in order to avoid disturbing oscillations of the machine.

Any remaining vibrations are compensated by feet with some free movement (Free-Force Compensation Sockets). This innovative FFCS technology is based on the d’Alembert principle and allows very small circular movements of the machine housing that result in an automatic mass compensation. The laboratory bench is only subjected to minimal frictional forces generated in the feet.

In this way the PM 100 ensures a quiet and safe operation with maximum compensation of vibrations even with the largest pulverization forces inside the grinding jars and therefore can be left on the bench unsupervised.

Supplied with: Planetary Ball Mill only. Grinding jars and grinding balls have to be ordered separately.
The PM 100 CM is a Planetary Ball Mill with a speed ratio of 1:-1. Size reduction is not so much achieved by impact but by pressure and friction which is more gentle on the material.
