  • Emax - La Revolución en la Molienda Ultrafina

    El Emax es un molino de bolas completamente nuevo, específicamente diseñado para moliendas de gran intensidad. Con una sensacional velocidad de 2.000 rpm que no ha sido alcanzada hasta ahora por ningún otro molino de bolas del mercado y unos recipientes de molienda de forma especial, su aporte de energía para la trituración es extremadamente alto. Este molino combina de forma extraordinaria los mecanismos de impacto y fricción con el movimiento circular de los recipientes de molienda, lo cual permite obtener partículas ultrafinas en tiempos extremadamente cortos. Su novedoso sistema de refrigeración por agua absorbe la energía calorífica excedente, de manera que la muestra no se recalienta, ni siquiera con tiempos de molienda largos.
  • Time Advantage in Pharmaceutical Research: Sample Preparation with the High Energy Ball Mill Emax

    The development of drugs with poorly soluble to insoluble active ingredients is a big challenge for the pharmaceutical industry. The bioavailability of orally taken active ingredients, which means to what extent and in which period of time the substance is ingested by the body and is available at the place of action, strongly depends on the percentage dissolved in the gastrointestinal tract. One way to improve the solubility and thus the bioavailability of active ingredients is the pulverization of these substances. By minimizing the particle size to the micron and submicron range the surface-volume-ratio is increased and the solubility of the particles is improved. The pulverized particles are suitable for use in a variety of dosage forms, for example classic tablets or capsules.
  • Emax - faster, finer, cooler

    The biggest challenge when developing a high energy ball mill is controlling the temperature. The very high energy produced by ball milling leads to an extreme heat increase inside the grinding jars. RETSCH solved this problem by creating an innovative integrated water-cooling system. Grinding breaks for cooling, which are unavoidable in conventional ball mills even after only 30 minutes grinding at moderate speed, are usually not necessary when using the High Energy Ball Mill Emax.
  • White Paper: Ultrafine Grinding with Laboratory Ball Mills

    How are nano particles produced? The “Bottom-Up” method synthesizes particles from atoms or molecules. The “Top-Down” method involves reducing the size of larger particles to nanoscale, for example with laboratory mills. Due to their significantly enlarged surface in relation to the volume, small particles are drawn to each other by their electrostatic charges. Nano particles are produced by colloidal grinding which involves dispersion of the particles in liquid to neutralize the surface charges. Both water and alcohol can be used as dispersion medium, depending on the sample material. Factors such as energy input and size reduction principle make ball mills the best choice for the production of nanoparticles.
  • Mechanical Alloying with High Energy Ball Mill Emax

    Alloys such as amalgam in dental medicine or stainless steel are universally known and used. The traditional way to produce alloys is to fuse the components at very high temperatures. If only small quantities are required or if the alloys cannot be fused by melting mechanical alloying is an alternative. For this application ball mills are ideally suited. They provide a high energy input due to the impact and friction effects which occur during grinding.
