The PULVIS is THE energy-optimised grinding system for ultra-fine materials. The vertical, dry agitator bead mill features an integrated dynamic classifier. Its strength is the ultrafine and low contamination grinding of hard materials. Size reduction processes of products such as ceramic materials or glass are very energy-intense. The finer the particles to be produced, the higher the energy that is required for the grinding process. The PULVIS meets these requirements and reduces your energy costs. Gain competitive advantages in dry grinding with our process engineering solution. fineness values down to d97 < 1μm up to 80% energy saving ultrafine grinding in the dry process steep particle size distributions sharp top cut PRINCIPLE OF OPERATION The milling part is located at the bottom of the machine. Feed material is ground by agitated media that combine impact grinding and attrition. The gasflow injected from the bottom side transports and cools the particles on their way through the grinding media. Ground particles are conveyed by air, passing through the grinding chamber to the classifier. The classifier separates the required fine product from coarse particles. The coarse particles return to the grinding zone for further grinding. FEATURES Compact, space-saving design From Laboratory to production scale: with possibility to scale-up over complete range Energy efficient: With high grinding efficiency specific energy consumption is reduced by up to 80 %. Finer particle sizes are possible compared to jet milling. Ultra fine particles: The compact unit reliably produces very fine products with particle sizes in the sub-micron range.
