Retsch Planetary Ball Mill PM 200 For 230 V 20.640.0001

PART NO: R20.640.0001

50/60 Hz with 2 grinding stations speed ratio 1 : -2

Planetary Ball Mills are used wherever the highest degree of fineness is required. Apart from the classical mixing and size reduction processes, the mills also meet all the technical requirements for colloidal grinding and have the energy input necessary for mechanical alloying processes. The extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and therefore short grinding times.

The PM 200 is a convenient benchtop model with 2 grinding stations.

Application Examples

alloys, bentonite, bones, carbon fibres, catalysts, cellulose, cement clinker, ceramics, charcoal, chemical products, clay minerals, coal, coke, compost, concrete, electronic scrap, fibres, glass, gypsum, hair, hydroxyapatite, iron ore, kaolin, limestone, metal oxides, minerals, ores, paints and lacquers, paper, pigments, plant materials, polymers, quartz, seeds, semi-precious stones, sewage sludge, slag, soils, tissue, tobacco, waste samples, wood.

Function Principle

The grinding 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.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 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

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.
