Charging a Dry Mill – The general operation of a grinding mill is to have the product impacted between the balls as they tumble. If there are insufficient solids in the mill then the media will strike itself and generate excessive media wear. If too much product then the solid may buffer the impact too much.

The material is charged into the mill at the top and is discharged out the bottom side, making use of centrifugal force. The HSA is used when smaller particle size (generally 40 mesh) materials are fed into the machine and micron size end product is desired. Also, it is often used for fibrous and polymer types of materials.
Wet Grinding, also known as wet milling, is a process of taking materials in a liquid or slurry form and reducing the particles by breaking them apart or shearing them down in size. Visit the Custom Milling & Consulting LLC, website to learn more about our wet grinding capabilities.
