Plastic chain operation

he maintenance of sludge scrapers is various depending on configuration and type. The main activities when completing maintenance of these mechanical machines are the transmission chain tensioning and greasing. The previous generations of scrapers are mostly of steel chain type configurations which need a lot of greasing, often there is oil escape which increases wearing on the steel roller chain / sprockets and contaminates the water. The wearing increases maintenance costs and the oil leakage causes a reduced efficiency of the treatment, in worst case there could be a major failure.
