In the mining, aggregates, and construction industries, crushing and screening production lines are the core systems that enable continuous production. As the equipment operates continuously under high-load, high-wear conditions, a lack of systematic maintenance management can easily lead to equipment failure, downtime, and even significant losses.
Therefore, establishing a scientific preventive maintenance plan is key to ensuring production stability and reducing operating costs.
Preventive maintenance refers to the inspection, servicing, and replacement of wear-and-tear parts on equipment at set intervals to prevent breakdowns.
This phased maintenance system effectively ensures the long-term, stable operation of equipment.
Compared to ‘repair after failure’, preventive maintenance offers clear advantages:
At the same time, modern production line equipment is complex, particularly mobile crushing and screening equipment; without data monitoring and maintenance management, this can very easily lead to a decline in production efficiency.
Routine inspections are the first line of defence in preventive maintenance and should be carried out at the start of each shift.
Key inspection items:
In addition, a pre-shift inspection must be carried out before starting up, covering the lubrication system, feeding system, and dust extraction system, to prevent operation whilst the equipment is faulty.
👉 This is the aspect that is most easily overlooked on site, yet it is also the most crucial.
Weekly maintenance:
Monthly maintenance:
For example, Runhang crushing and screening equipment features an optimised structural design that makes key components easier to maintain, helping to reduce maintenance costs and downtime.
Annual maintenance is a crucial part of ensuring the long-term, stable operation of equipment. These mainly include:
Regular overhauls can prevent equipment from operating whilst faulty and help avert major breakdowns.
👉 Changes in power are a key indicator of equipment malfunction.

Many equipment issues are not discovered only after a failure has occurred, but rather because changes in trends have gone unmonitored.
We recommend focusing on the following monitoring parameters:
For example, if the coast time changes after the equipment has stopped, this may indicate a problem with the bearings or alignment.
To improve maintenance efficiency, it is recommended that a standardised management system be established:
Preventive maintenance is not just about equipment; it also involves management:
Spare parts management:
Personnel training:
Experienced operators can detect anomalies early on and prevent major breakdowns.
Whilst preventive maintenance does incur additional costs, the long-term benefits are significant:
