If this occurs, and the undesirable gypsum is exposed to moisture, build-up can occur. Gypsum build-up, if left untreated, will eventually wear down moving parts and result in maintenance issues for processing and material handling equipment. Consistent removal of material build-up is recommended in order to counteract this issue.
