Processing mineral rocks, mineral dust, binders (bitumen) and additives into asphalt mixtures is a complex procedure. In addition to many safety aspects, staff and equipment are faced with tough challenges, such as varying temperatures, extreme dust and dirt, and hard-to-reach lubrication points. Continuous lubrication of machine elements is an important factor to prevent equipment breakdown and to increase economic efficiency.

The most important equipment in asphalt mixing plants is the mixing module. It is exposed to high temperatures and strong vibrations. If it fails, the entire production stops. Preventive maintenance is often neglected due to low staffing levels. The results are downtimes, delays and high repair costs. Automatic lubrication will reduce downtimes and repairs – especially when regular maintenance is neglected due to high workloads and staff shortages.

perma lubrication systems provide reliable lubrication for many applications in asphalt mixing plants. Bearings and lubrication points are protected against abrasive wear, contamination and liquid ingress. perma lubrication systems can be programmed to discharge exactly the amount of lubricant required by individual lubrication points over a certain period. This enables you to plan your maintenance operations. Lubrication of hard-to-reach lubrication points or on rotating machine parts is dangerous and difficult. Remote mounting of perma lubrication systems with grease lines provides easy access to these areas and increases workplace safety.

The automatic lubrication system perma NOVA is ideal for asphalt mixing plants, especially for the lubrication of thrust roller bearings or pillow block bearings. It can compensate changing temperatures and works reliably from -20 °C to +60 °C. perma NOVA is also easy to use. The discharge time (1 to 12 months) can be selected with a push button on the reusable control unit. The replaceable lubricant cartridge is available in two sizes (65 cm³ and 125 cm³).
