Feed chute liners
Chute liners protect the structure where material falls and slides. The grade depends on whether the liner is struck by falling rock or rubbed by sliding material.
- Works in
- Chutes, hoppers and transfer points feeding crushers, mills and conveyors.
- Industries
- Cement, Mining, Aggregate, Thermal power and steel
- Materials
- High-chromium iron, Ni-Hard, Cr-Mo steel, Manganese steel
- Size
- Single pieces from 3 kg to 7 tonnes, to drawing
- Supplied
- As cast, or machined to drawing
- Inspection
- Chemistry and hardness on every heat; UT, MPI or DPT and a dimensional report as specified
- From a worn part
- Yes. Send the part or photographs with key dimensions and we will reverse-engineer it
01
How it fails and what we do about it
- 01Sliding abrasionWhite iron where impact is low.
- 02Impact damage at the drop pointManganese or Cr-Mo steel where rock lands.
- 03Liners working looseCountersunk fixing holes and fit to drawing.
02
Choosing the grade
Typical values from the governing standards. A metallurgist confirms the grade for your duty with every quotation.
Ni-Hard (nickel-chromium white iron)
Sliding abrasion with little impact, as an alternative.
ASTM A532 Class I · IS 4771 · ISO 21988 / EN 12513
Cr-Mo and martensitic steels
Mixed impact and abrasion.
IS 4896 · Customer specification
Austenitic manganese steel
Heavy impact at the drop point.
ASTM A128 · IS 276 · EN 10349
03
What we control
- Grade set by the dutySliding wear gets white iron; impact at the drop point gets tough steel.
- Made to drawingFrom the drawing, or from a worn liner reverse-engineered in-house.
- Fixings to fitCountersunk holes and fixing faces held so liners sit flush.
- Tested and recordedChemistry and hardness reported for every heat.
04
