We help our customers to understand what is possible by sharing what we call our 'Particle Size Card' - this sizing chart ties the target particle size to the mill type and the size of round or grater hole screen required in partnership. Armed with the Particle Size Card, you'll be able to work with our team to achieve the exact PSD you need.

The size of the beads required for milling particles is 10 to 30 times the maximum particle size of the raw material and 1,000 to 3,000 times the mean particle size after milling. For example, when grinding calcium carbonate of 10 μm as the largest size of raw material to final-size particles of 100 nm, it is recommended to use 0.1 mm beads.

Treatments were 1) a 40:60 blend of coarsely rolled (in a roller mill) and finely ground (in a hammermill) corn with a large standard deviation (sgw) of particle size (sgw of 2.7), 2) hammermilled corn with an sgw of 2.3, and 3) roller-milled corn with an sgw of 2.0. Mean particle size of the corn was approximately 850 microns for all treatments.

You must identify the particle size distribution and then configure your mill to target the requirement. *(Particle analysis should also be performed on the pre-grind phase. It does not matter which type of mill you are currently using, all grind processes can be improved by improving the pre-grind, see my previous article for help with this step)

How the mill achieves uniform particle size To achieve a uniform final particle size with minimal fines, the roller mill must have the right roll surface, roll speed ratio, and roll gap for your application. Roll surface. Typically, the roll surface is corrugated rather than smooth to achieve efficient size reduction, as shown in Figure 3.
