Mori cu energii mari de măcinare
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).
Moară cu bile cu energie mare Emax, cea mai puternică din portofoliul RETSCH, atinge cel mai mare consum de energie cu viteze de până la 2000 rpm, rezultând o accelerație de 76 g. Acest lucru, combinat cu principiul său unic de funcționare și designul vasului de măcinare, produce o distribuție a dimensiunii particulelor excepțional de îngustă, minimizează timpii de măcinare sau de reacție și generează particule ultrafine. În plus, designul său asigură mișcări ale bilei cu impact și frecare simultane, ceea ce sporește efectul de amestecare.
Moară planetară cu bile PM 300 dispune de o roată solară mare și o viteză maximă de 800 rpm, atingând accelerații de până la 64,4 g. Împreună cu opțiunea de a utiliza patru recipiente mici, suprapuse, de măcinare, cu dimensiuni de la 12 la 80 ml, pentru operațiuni la scară mică, sau două recipiente cu dimensiuni de până la 500 ml pentru extindere, acest model este foarte potrivit pentru aplicații de cercetare în mecanochimie.
PM 400 cu patru stații de măcinare este disponibil cu rapoarte de viteză de 1:-2,5 și 1:-3, rezultând un consum ridicat de energie, de obicei benefic pentru aplicațiile mecanochimice.
Morile de amestecare MM 500 nano și MM 500 vario funcționează la o frecvență maximă ridicată de 35 Hz, rezultând o accelerație semnificativă. Acest lucru accelerează procesul de măcinare, îmbunătățește finețea particulelor și crește consumul de energie pentru reacțiile mecanochimice.

Mori cu energii mari de măcinare - 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.
