Efficient recycling processes depend crucially on the condition of the machines used. Shredders, granulators, presses, and crushers operate under high loads and therefore require regular maintenance. This is the only way to avoid breakdowns and ensure operational safety. This article shows which maintenance intervals are mandatory, which regulations apply, and why preventive maintenance is economically indispensable.
Recycling machines are exposed to dust, dirt, and heavy material flows on a daily basis. As a result, knives, bearings, screens, and hydraulic components wear out faster than in many other machines. Without regular maintenance, there is a risk of unplanned downtime, high repair costs, and risks for employees. Consistent maintenance ensures that wear parts are replaced at an early stage and that the system continues to operate reliably.
The exact intervals depend on the machine type, manufacturer's specifications, and intensity of use. Nevertheless, certain guidelines have become established throughout the industry.
Cutting and shredding machines should be serviced approximately every 250 operating hours. During servicing, the blades are checked, lubrication points are serviced, and screens are inspected.
Granulators and crushers generally require maintenance every 500 operating hours. Typical tasks include work on bearings, drives, and filter systems.
Presses and hydraulic systems should be checked at least once a month. The focus here is on the oil level, as well as seals and the function of the control system.
Conveyor technology and sorting systems are usually serviced every six months. During this service, sensors, belt tensions, and lubrication points are checked.
Electrical systems and controls require an annual safety inspection in accordance with DGUV regulations, as well as an inspection of all connections.
All intervals mentioned are related to legal requirements such as the DGUV and the Industrial Safety Regulation. Operators are obliged to carry out maintenance and document it.
Maintenance includes scheduled maintenance work to prevent wear and tear. Servicing considers the entire system and consists of maintenance, inspection, repair, and improvement. A professional servicing strategy reduces costs in the long term and significantly increases the service life of the recycling machine.
Recycling machines give early indications that maintenance is required. These include unusual noises or vibrations, a drop in throughput, leaks in the hydraulics, overheating, or conspicuously high power consumption. Recognizing these warning signs and reacting early can prevent expensive machine breakdowns.
According to the Industrial Safety Regulation, all maintenance must be documented. This includes the date, type of work performed, person performing the work, and any replacement parts. This documentation is important for providing evidence during inspections and for maintaining a complete machine history.
Recycling machines must run reliably to ensure economical and sustainable processes. Fixed maintenance intervals are mandatory because they minimize downtime, protect employees, and extend the service life of the equipment. A binding maintenance plan, tailored to the machine type and frequency of use, is essential for every operator.
