Dealing with particle abrasion wear in coal processing

The impact of particle abrasion wear on equipment used in coal processing can be significant. Ever-persistent abrasion and wear takes a major toll on centrifuges, pulverisers, conveyors, chutes, augers, and other equipment. It can ultimately cause unexpected, costly downtime or greatly reduced equipment life.

For a major coal mine in Queensland, high abrasion from coarse coal in the dewatering centrifuge – used to extract excess water before stockpiling– meant the mine had to partially dismantle the centrifuge and remove the four chutes every 12 to 15 weeks to re-coat the internal surfaces of the chutes with a wearing compound. The frequent re-coating required a minimum of 72 hours of labour time, over a 12-month period.
