The bolts you loosened above the built in wedges are supposed to draw them up to close the gap on the lower portion of the jaws.

Try welding 1 inch rebar rods to the face if the plates.

[@williamhoward8319]

cut some shims for the wedges then tighten your bolts

[@abeonthehill166]

You should have chiselled into the lower stone a type of depression or track to make sure the vibration would not disturb the wedges .

Great video. I wonder if it would have been easier to stick a bottle jack between the jaw and crusher housing to push it forward instead of beating in the wedges? good idea with the strap however.

[@barnsandbrews]

Ah yeah good idea! Didn't think to use a bottle jack!

[@radiootoo]

What is the make of your crusher?

[@adv4good]

Put a small jack between the wedges in that void between them. The rest will come to you friend

[@markmayer2029]

Why don't you make a longer toggle plate?

[@ilgiz242]

safety precautions - no, we haven’t heard!

Might be cheaper to just screen your crushed stone.

Did you adjust the wedges built into the jaw crusher? That system should adjust to somewhere between 20 and 40mm when drawn fully in.

[@barnsandbrews]

Yeah I adjusted the wedges to make the gaps as small as they would get but it still wasn't the size material I wanted so I added the additional wedges. The jaw plates are a little worn which adds to the size of the gap
