Abstract

Operating a Plough Scraper and a Tilting Device should be very easy and safe. As much as the installation and maintenance is cheaper it does not require too much for both operation and maintenance. Some systems are automated with the plant and needs no operator to operate manually. Non-automated systems needs only 1 operator of part time basis to operate and only when the system is engaged or in lowered position. Interlocking for the 2 conveyors was ensured to protect the system from blockages and spillages. Once the scraper is lowered material is being scraped from the 4000 tpa conveyor to the 2000 tpa conveyor. The rest becomes just monitoring with no physical contact to the running system. When scraping is completed, the plough is lifted to allow material to pass straight to another feed being Eskom Medupi feed line. The system is easy to operate with 4 main buttons being Tilting Device lifting and lowering, Plough Scraper  lifting and lowering. Once the Tilting Device is lifted and Plough lowered interlock kicks in to reduce the feed from the 4000 tpa. Once the Tilting Device is lowers with Plough lifted the interlocks is eliminated to now feed 4000 tpa.
