Mill feed spouts
The feed spout carries the full feed of the mill at its point of heaviest wear. Cast spouts hold their shape where fabricated ones wear through and keep the mill inlet sealed.
- Works in
- Feed spouts that deliver clinker and additives into ball mills.
- Industries
- Cement
- Materials
- High-chromium iron, Cr-Mo 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

How it fails and what we do about it
- 01Wear where the stream turnsWall thickness and grade set for the wear zone.
- 02Wear-through at the inletHarder grade at the point of impact.
- 03Leaks at the flangesFlange faces and holes machined to drawing.

Choosing the grade
Typical values from the governing standards. A metallurgist confirms the grade for your duty with every quotation.
Cr-Mo and martensitic steels
Where larger pieces strike the spout.

What we control
- Hardened through the sectionWhite iron alloyed and heat treated for the thickness of each segment, not just its surface.
- Structure checkedMicrostructure examined with an image analyser, so carbide and matrix are verified, not assumed.
- Fit as a setSegments checked against each other and against gauges so they assemble without forcing.
- Machined to drawingBores, journals and fixing faces finished on vertical lathes and machining centres.
