HANOVER, MA -- New Sturtevant “Open Manifold Micronizer®” disassembles in minutes allowing total access to all internal chambers, the internal material grinding chamber & compressed air manifold, for easy, complete cleaning of the entire unit.
Based on Sturtevant’s Sanitary Design Micronizer® technology originally developed for pharmaceutical level cleanliness, the New Open Manifold Design Micronizer® has no inaccessible enclosed areas which could trap contaminants, simple jet removal for quick clean up or inspection and is constructed for rugged life in industrial applications where process changes and fast return to service are critical. In many cases this mill can be taken out of service, disassembled, completely cleaned with residue of previous material entirely removed, reassembled and returned to service in less than one hour.
The New Open Manifold Design Micronizer® pulverizes chemicals, pharmaceuticals, ceramics, pigments, cosmetics, and minerals to narrow fine particle size distributions with no moving parts. The Micronizer® grinds and classifies powders to low and sub-micron particle sizes in a single operation using high pressure air, gas or steam to induce particle-on-particle impact reduction. The product size is controlled by the operating pressure, which affects the particle collision velocity and by the feed rate, which affects the powder’s retention time in the grinding chamber. Particles are size classified by centrifugal force that holds larger particles in the grinding area and centripetal force that drags finer particles into the vortex for discharge.
A variety of replaceable liners provides protection against wear and contamination. For processing abrasive powders, product contact parts can be made from Aluminum Oxide, Tungsten Carbide, Zirconium Oxide, Silicon Carbide, as well as many polymeric compounds. A full range of laboratory, pilot plant and continuous production models are available and Sturtevant has complete Micronizer® system capabilities.
Before purchasing a Micronizer®, customers are encouraged to send a representative sample of powder to the Sturtevant test lab. Here the sample is processed at several test conditions to determine the finest particle size that can be achieved and to develop a correlation between capacity and fineness. Product fineness is characterized using an air jet sieve and a laser particle size analyzer. Sturtevant encourages witnessed trials so that customers may learn more about the mill operation.
Since 1883, Sturtevant Inc. has supplied innovative solutions to the ceramic, chemical, pharmaceutical, mineral, and food processing industries throughout the world. Backed by experienced technical support, Sturtevant equipment is known for its efficiency, accuracy, and dependability.
