    ing (e.g., plugging the hammer mill screen or blocking the air classifier of a jet mill), and collection (e.g., plugging the bag filters). There are two ways to grind sticky materials. The first solution is to dry the material prior to grinding, or dry and grind it at the same time by sweeping hot air through the mill.

    Up to that time, dry grinding in the sub-sieve range of 625 to 2500 theoretical mesh size range was impractical. In a jet mill, the temperature of the air leaving the jets is cooled to about -200 degs F due to the Joules Thompson effect and the product leaves no warmer than the air used for the grinding.

    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.

    Why HPGRs are revolutionising mill circuits

    Aug 07, 2019 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.
