MICROSEPARATORS TYPE "MS"
Our micro-separators type MS are suitable to extract the finest fraction from dry powders, however produced.
In particular, they are designed to provide a cut size in the range 10÷40 micron, usually not possible with classic self ventilated air classifiers.
• Easy adjustment of product fineness.
• Constant granulometry of the fine fraction, even when the feed material is not constant for rate and granulometry.
• Minimum maintenance.
WORKING PRINCIPLE
Two products are always obtained from micro-separators type MS:
A) Finest fraction, finer than 10÷80 micron according to the adopted regulation
B) The remaining fraction with a low content of finest particles.
A part of the finest powder, in a percentage variable according to the specific application and regulation, remains mixed to the residual fraction.
The residual fraction B can be:
• Used for applications requiring a lower fineness.
• Sent again to the micro-separator for a complete extraction of the fine product A.
• Ground again with suitable mills.
CENTRIFUGAL FORCE of a rotating classifying wheel, that throws the particles towards the outside walls of the machine with an effect a proportional to their mass and definitively to their dimension.
DRAFT FORCE of the air stream, that draws the finest particles through the special vanes of the steel rotor.
The CENTRIFUGAL FORCE is controlled by changing the rotor speed while the DRAFT FORCE can be varied changing the speed of the air stream.
With suitable adjustment of these 2 forces, the requested cut size is obtained.
