A tablet compression machine preventive maintenance schedule lists the checks and jobs done on the equipment at fixed intervals, how long each takes, and in what order of frequency, so problems are found before the tablet compression machine fails. This page gives the schedule used in the PlantOps360 task library for tablet compression machine (rotary tablet press), which follows common industry practice for general-purpose equipment. It is also searched for as tablet press, rotary press, compression machine, punches and dies.
The maker’s manual and your site safety procedures always come first where they differ. Intervals set by law differ by state.
