Adjusting the Scalper:

A properly adjusted scalper is important for maintaining grind efficiency and mill safety. You adjust your scalper by varying the angle of the baffle (a rod with a steel flap attached). The baffle is used to constrict the amount of grain flowing over the scalper grate, which consists of long, thin metal rods that sift foreign materials from your pre-grind product.

Adjust the baffle until product comes within 3” of the scalper discharge, as shown in Figure 14. This sifts out the maximum amount of foreign material while ensuring minimal product waste.
