Summary Soybean was finely ground with a modified double‐disk attrition mill by a wet‐grinding process. The hydrostatic pressure in the gap between the rotating and stationary disks of the mill decreased with radial distance between the central inlet and the peripheral exit in the disks. Observed values were in good agreement with theoretical values derived from Bernoulli's equation. The maximum hydrostatic pressure was found at the feed entrance zone of the gap under any given operational conditions. The effects of rotational speed, gap width and soybean feed concentration on the hydrostatic pressure were measured. This implied that increase in hydrostatic pressure from height of feed head and/or increased speed will increase output.
