Mills or Complete Systems Buy or Lease – Your Choice The Operating Principal P ulverization takes place in the central chamber of the Micron-Master® jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved.

Fluid energy milling, sometimes referred to as air jet milling, effectively reduces the size of drug particles from the range of 20–100 μm to less than 10 μm. In this micronization method, high velocity compressed air streams are injected into a chamber where the starting raw materials are fed by a rate-controlled feeder ( Fig. 1 ).

Jet mills are generally capable of reducing large feed stock of ½ in.1 down to below an average particle size of 5µm. The size of the feed stock is limited to what the feed funnel of the mill will accept as a free flowing material. It may not be well known, but there are three physical laws that describe the energy required for size reduction

The air classifier mill combines a mechanical impact mill with an integrated dynamic air classifier. It is an air swept mechanical impact mill designed to grind materials down to 10 microns. The air classifier mill uses air to carry the product through the fine grinding milling machine and classifying process.

Jet mills operate in compressed air, gas or high pressure superheated steam. Jet mills have no moving parts, thereby eliminating contamination due to contact with external grinding media. It is also an ideal process to grind heat-sensitive and waxy material because no attritional heat is generated. Jet mill works on fluid energy.

The principle behind blowing steam is to clean the lines, i.e. to give it a thermal shock, i.e. heating and cooling with high velocity gas flowing through the line will shock the pipe to break the mill scale and weld slag away from the pipe wall. 3.1 Objectives The following are to be removed from plant critical

Three types of separators each with a high-precision method of classifying particles according to size or density. For dry materials of 100 mesh and smaller, air classification provides the most effective and efficient means for separating a product from a feed stream for dedusting, or for increasing productivity when used in conjunction with grinding equipment.

4. Jet milling for tungsten carbide. Because of its operating principle, the jet mill can handle extremely abrasive materials as particles are impacted against each other and not against the internal components of the mill. It is suitable for ultra-fine size reduction of extremely hard materials such as tungsten carbide with a Mohs Hardness of 9.5.

Milling is the machining process in which the removal of metal takes place due to the cutting action of a rotating milling cutter.In a milling machine, the cutter is rotating due to workpiece is fed against it.This machine can hold more than one tool at a time. The cutter rotates at high speed, and because of the many cutting edges, it removes metal at a very fast rate.
