Housing & Rotor Engineering
The Doebritz Portable Cone Mill features a fully polished 316L stainless steel housing with a unique cone-shaped chamber that directs material toward the precision-machined multi-blade rotor. The rotor operates at adjustable speed (up to 1500 rpm) with an outboard bearing arrangement to eliminate product contamination. The wedge-lock screen frame requires no tools and ensures zero bypass of oversized particles.
