We’re back with more of the most commonly asked questions about the Sturtevant Micronizer®.
As mentioned in Part 1 of the Micronizer FAQ’s, Sturtevant developed the first jet mill technology. But every day we come across new and varied materials that our customers need help processing to the finest particle size, and we’re here to help!
Below are some of the more common questions we are asked about our Micronizer:
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.
Can a cyclone be substituted for filter bags to collect my product?
Yes and No. 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.
Can the Micronizer be used for explosive materials?
Whoa! But yes, the Micronizer is designed to operate in various conditions including fully inert, explosion isolated and is able to be customized to meet your specific concerns. Compliance with local and national codes and knowledge of Kst and Pmax are ultimately the customer’s responsibility.
