The workpiece is placed in a fixture under the rotating grinding wheel. The wheel then moves horizontally across the material and grinds down the workpiece surface in one or more steps until the desired thickness or surface roughness is achieved. To avoid that the material becomes too hot due to friction a coolant (cutting fluid) is often machine can be manually operated or CNC.

The Ball mills are much like the Rod mills except that they use balls as their grinding media. The size of these balls may range from three quarters of an inch to over five inches in diameter. There is a definite difference in the grinding performance between a Ball mill and a Rod mill. The Rod mill has a higher impact force than a Ball mill.

In pilot plantscale wetmilling of corn, Anderson (1957) and Rubens (1990) closely simulated the industrial practice by using a Bauer mill and a Foostype mill, respectively, for the first grind. Both the Bauer mill and the Foostype mill are attrition mills with one rotating and one stationary plate, each equipped with spiked tooth blades.

Wet milling with IKA's inline machines is a safe and efficient alternative to dry grinding. Dry grinding creates a lot of dust which causes the need for proper filtering systems. This can be of particular importance during grinding of substances whose dust, when mixed with aerial oxygen, can result in explosive mixtures.
