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.
High Pressure Grinding Rolls are generally thought to only be effective in controlled "dry" grinding applications, however (depending on the material saturation level) they can readily process minerals well above 10% moisture. This gives HPGR's the flexibility to fit into a wide array of applications with both wet and dry classification.

Step 2. Since the grinding was carried out in a wet overflow mill in closed circuit, the value of k should be taken as 350 ( Table 7.2 ). Substituting data into Equation (7.16), we get the replacement size of grinding balls as. d B = 25.4 6250 350 0.5 2.4 × 12.8 75 3.281 × 1.5 0.5 0.33 = 61 mm. Step 3.
The Air compressor CFM chart will help you to know about the average CFM requirement for many of the air tools. Remember that air tools are usually rated about 25% duty, which means out of every 60 seconds, they are active for 15 seconds on a continuous use such as grinders. Take a look below at the air compressor CFM vs. psi chart.
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. Size reduction is the result of the high-velocity collisions between particles of the process material itself.
