Why should I consider using super-heated steam?
The high density of super-heated steam provides more aggressive milling compared to compressed air. Super-heated steam is ideal for very hard materials or applications requiring higher capacities.
Will the Micronizer contaminate my powder?
The Micronizer offers one of the best ways to reduce a powder with very little risk of contamination. The mill uses particle on particle impact to reduce a powder, incidental contact will occur with the mills body. To further protect a powder from contamination Micronizer can be lined with Stainless Steel or Pureline.
How is the particle size of a Micronized powder controlled?
Feed rate is the principle method of controlling particle size. Slower feed rates produce finer products and fast feed rates produce larger particles. Second to feed rate changes in grinding air pressure will change particle size. Additional methods are used to precisely control final particle size.
Can the Micronizer blend TiO2 with dispersants or other additives?
Micronizer intensely blends all materials to uniformity.
Can a cyclone be substituted for filter bags to collect my product?
This depends on the final particle size of the product and the type of cyclone being considered. Coarser product can be collected in a cyclone and the exhaust air can be sent to a central dust collector. Fine products require a secondary filter to ensure all of the product is collected. Typically cyclones are inefficient below 3 microns.
What shape are Micronized particles?
Micronized particles are typically spherical. The particle-on-particle grinding method tends to round any irregular shapes.
Does the Micronizer classify particles?
Yes, the Micronizer classifies particles as they are milled. The centrifugal force in the milling chamber retains large particles to be further reduced. The vortex classifier controls the size of particles that can escape before being fully milled.
What causes premature jet nozzle wear?
With other brand jet mills this is a common occurrence due to the design of their nozzles and jet wall. Sturtevant uses a proprietary nozzle design and special mill geometry that greatly increases nozzle life.
What is the maximum temperature of the super-heated steam?
The recommended temperature for super-heated steam is 550°F/288°C. It is critical for the steam to be hot enough to stay in gas form through the collection process but not so hot as to cause damage to collection bags and seals.
