Fixed and movable jaw plates, toggle plates and side liners for Sandvik CJ211, CJ409 and CJ412 jaw crushers.
CJ211, CJ409, CJ412. Three frames, one plate family, and a profile choice that matters more on the small frame than most buyers expect.
Jaw plates are bought on price more than any other wear part, which is why the wrong profile gets run for months before anyone adds up the cost per tonne.
Quarry rock wants tall teeth, wide spacing and a plate that grips a slab. Construction and demolition feed wants a lower, more corrugated profile, because the material is already broken and what it needs is turning rather than gripping. Running a quarry profile on C&D feed gives poor nip and a plate that wears at the tips. Running a C&D profile on quarry rock gives poor grip and a bent toggle. We ask what is going into the hopper, not just which model the machine is.
A small frame moves fewer tonnes, so the plate cost is spread over less material. That makes profile choice and change timing much more visible than on a large machine: two weeks of extra life on a big frame is a rounding error, on a CJ211 it is a real number. We will do that arithmetic with you if you send the throughput and the hours per plate.
Most CJ plate orders also need a toggle or a set of side liners, and ordering them separately means two freight costs and two waits. We quote the group together and state which items are castings and which are machined from plate, because the lead times differ.

CJ211, CJ409 and CJ412, with plates, toggles and side liners listed per model above.
They belong to the same parts family in the sense that JM is the earlier designation, but they are different frames with different plate sizes. Send the machine plate and we confirm which casting applies.
Yes, to drawing. Non-standard profiles are common on CJ frames because the same machine runs different duties at different sites.
