Horizontal Shaft Impactor Liners

Unicast Horizontal Shaft Impactor (HSI) wall liners, side liners, and apron liners deliver outstanding wear life for significant savings in production and operations costs.

Cast in WR1 for maximum durability, Unicast wall liners outwear fabricated steel plate liners 4:1.

To further increase wear life, Unicast engineers balanced the wear by tapering the liner at the top and increasing the thickness in the high wear zone.

Our proprietary design, impossible to recreate with fabricated steel, eliminates the high costs of short wear life, downtime, and labor found in traditional liners.

Features & Benefits

  • High-strength WR1 alloy far outlives fabricated steel in high impact environments, resulting in less HSI Crusher downtime
  • Guaranteed to fit - custom-fit and designed to suit your specific needs.
  • A cement plant in Ottawa, Ontario, reports 4 times the wear life out of Unicast wall liners compared to previously installed fabricated steel plate liners.
