This unit pictured here is a 3 inch, bottom driven cone mill capable of processing wet or dry products. It can be used for sieving, delumping, size reduction or calibration. This is a small bench top unit designed for R&D and formulation development work.

The CroMills utilize a vertical, "bottom-driven" impeller blade which, depending on application, uses air or nitrogen to seal the rotor shaft. Product falls vertically down into the perforated cone, (which may be referred to as a "calibration cone") where it is thrown against the inside walls of the cone by centrifugal force. The particles are reduced in size by the action of the rotating impeller blade that imparts centrifugal forces on the material, which forces the material through the holes in the cone. The perforated cones are interchangeable and come some with different sized and shaped holes to suit the application. The speed of the impeller blade also has an effect on the size and shape of the resulting particles: low blade speed results in relatively larger particle sizes while higher speeds create smaller sized particles.The gap between the impeller blade and the calibrating cone also has an import

The gap between the impeller blade and the calibrating cone also has an important effect on the milling process. Cronimo mills are supplied with spacer rings that makes it easy to adjust the gap between the blade and the cone. The CroMill rotor and motor assembly are dynamically balanced and the CroNiMo air or N2 shaft seal prevents the build-up of material at the shaft and eliminates the possibility of seal material from getting into the product. The shaft speed is variable and the rotor drive shaft disconnects from the mill body via a tri-clamp fitting for easy assembly, disassembly and cleaning. The inlet hopper comes with an inlet-in-position safety sensor.
