For fine and ultrafine crushing
The product is brought into the milling chamber where it circulates in a current of air. A grooved stator causes major turbulence which creates pressure differences causing the material to vibrate.
This vibration, which can reach several kHz, helps to fragment the product. The grain size adjustment uses several parameters such as: peripheral speed, holding time of the product within the device and the volume of transfer air. The grain size distributions which can be obtained with this type of equipment is generally between 100 and 1000 µm. Throughput can reach 1500 to 2000 kg/h.
There are numerous operational benefits such as, for example, low temperature milling to reduce humidity losses or the treatment of heat-sensitive products without adversely affecting the organoleptic properties of the milled products.
