Sandvik CH series cone crusher wear parts

Mantle, concave and bowl liner castings for Sandvik CH420, CH430, CH440, CH540, CH550, CH660, CH870 and CH880. Seven chambers, variants A, B, HC, FF.

The CH range is the current designation for the machines that were sold as H2800 through H8800. This page covers CH420, CH430, CH440, CH540, CH550, CH660, CH870 and CH880, with the castings listed per model.

The CH440 is the model that shows why this range needs more care than a part-number lookup. Seven chambers, mantles in four variants. Two enquiries quoting the same model can genuinely need different castings.

EF is not a marketing setting

The EF cavity is extra fine and belongs in tertiary duty on a controlled, screened feed. Put it behind a jaw on a feed with any oversize and the chamber will not take the load: the crushing zone is short, the material has nowhere to go, and you get packing, a spike in power draw and a liner that fails at the top rather than wearing down. If an enquiry asks for EF on a secondary application, we ask about the feed first. Sometimes the right answer is a different chamber and we say so.

The 870 and 880 are a logistics problem as much as a casting problem

A CH880 bowl liner is a heavy casting, and the practical contraints are pattern availability, crane capacity at both ends and the shipping window. We plan these before we quote, because a delivery date built on optimism is worse than a longer date built on the foundry schedule. For this size we normally ask for the drawing early and confirm the handling arrangement in writing.

Measuring wear so the next order is not a guess

Record the bowl liner thickness at the same four points every time, at the same interval, and write the hours against it. After two liner lives you have a wear rate for that machine and that chamber, and the next order becomes a date rather than a guess. Without the record every reorder is done on feel, and that is why some plants replace at 60 percent and others at 20.

Common questions

Which CH models are covered?

CH420, CH430, CH440, CH540, CH550, CH660, CH870 and CH880, listed in the table above with parts and supply basis.

Do you cover the CS range as well?

Yes. CS420, CS430 and CS440 sit in the same fitment set and follow the same chamber and variant logic.

How do I know which mantle variant I need?

From the machine duty and the marking on the casting you are replacing. Send the marking or the drawing. Guessing the variant from the model alone is how the wrong alloy gets supplied, and the mistake only shows up at the end of the liner life.
