Search preventive maintenance schedules

A preventive maintenance schedule for mines and mineral processing plants is the plan of checks, services and inspections that keeps the plant’s equipment running between breakdowns. Heavy mobile fleet, crushers, conveyors, dewatering and ventilation in remote sites. Services follow engine hours as well as calendar time, and statutory examinations apply.

Below are the equipment types we list for this industry, each with its own preventive maintenance schedule and checklist, and the common utilities every plant has. The tasks and intervals follow common industry practice; the maker’s manual and site safety procedures come first.
