Polyether ether ketone (PEEK) is a high-temperature, high-performance thermoplastic special engineering plastics. It has good mechanical properties and resistance to chemicals, resistance to abrasion, resistance to hydrolysis and other properties. Its light weight, self-lubricating properties, good flow properties and processing properties can be filled with carbon fibre, graphite, molybdenum disulphide, etc. to further improve the lubricating properties and mechanical strength. Case Study done by KECPL Name of the wear part: Bead Mill Disc Problem: Bead mill plates are subjected to abrasion and mild impact caused between continuously striking Zirconia bead and finely powdered product. Cause of the problem: Zirconia beads and powdered product are abrasive in nature. The MOC of the bead mill plate selection should allow a combination of elasticity and hardness yet reduce zirconia bead breakage. Solution: Bead mill working parameters were set to reduce zirconia bead breakage. Bead mill plates were manufactured as follows: (a) SS 410 forged ring was welded to an alloy steel plate. Subsequently the fabricated plate was machined to required dimensions. (b) Polyether based polyurethane of 3 to 5mm thickness was injection molded or cast on the pre fabricated plate. P.U. has a hardness of 90 Shores. From MS roll to an antistick hard surface.
