Hoge energie Kogelmolens
High energy input significantly enhances grinding efficiency, leading to finer and more homogeneous particle size distributions. This is crucial in applications where the quality of the final product relies on its particle size and distribution. In challenging applications like mechanochemistry, the energy input, along with the action mode, temperature, ball mill size, and mixing effects, can influence the reaction outcome. To facilitate experiments across a spectrum of speeds, from moderate to high energy, four RETSCH models are particularly noteworthy: PM 300, Emax, MM 500 nano, and MM 500 vario. The acceleration these mills can achieve depends on the sun wheel size and maximum speed (planetary ball mills) or amplitude and frequency (mixer mills).
De Hoge Energie Kogelmolen Emax, de krachtigste in de Retsch portfolio, bereikt de hoogste energie-input met snelheden tot 2000 rpm, wat resulteert in een versnelling van 76 g. Dit, gecombineerd met zijn unieke functieprincipe en Slijp jar ontwerp, produceert een uitzonderlijk smalle Deeltjesgrootte Verdeling, minimaliseert Slijpen of reactietijden, en genereert ultrafijne deeltjes. Daarnaast zorgt het ontwerp voor kogelbewegingen met gelijktijdige impact en wrijving die het mengen effect verbetert.
De Planetaire Kogelmolen PM 300 beschikt over een groot zonnewiel en een maximale snelheid van 800 rpm, het bereiken van versnellingen tot 64,4 g. Samen met de optie om vier kleine, stapelbare Slijpen potten van 12 tot 80 ml voor kleinschalige bewerkingen, of twee potten van maximaal 500 ml voor opschaling doeleinden, is dit model zeer geschikt voor onderzoek in de mechanochemie.
De PM 400 met vier Slijp stations is beschikbaar met snelheidsverhouding 1:-2.3 en wat meestal resulteert in een hoge input voor mechanochemische toepassingen.
De Mixer 500 MM en 500 MM werken met een aanzienlijke variabele energie-invoersnelheid, wat resulteert in een hoge variabiliteit van de mechanosnelheid, waardoor de mechanochemie verbetert.

Hoge energie Kogelmolens - FAQ
Why is a high energy input required?
A high energy input is beneficial for mechanochemical applications as it helps to increase the yield; for very hard samples to crush them more efficiently; for research in general as it provides more options to try out different settings.
Is it always beneficial to work at maximum speed to increase the energy input?
No, it strongly depends on the sample material and application whether a very high energy input is beneficial. For some materials it may lead to undesired caking effects due to the sample getting warm. A warming effect also needs to be avoided for temperature-sensitive materials.
Is cooling required for high energy ball mills?
Yes, cooling helps to compensate the warming effects. Another option is working with cooling breaks.
