hi Justin,
the hopper at its highest would be 250-300mm high and the crusher box
is around 80mm x 50mm and full length of machine conveyor included would be around 1.2 meters
the crusher box is just big enough for Bob to fit in, wonder what would happen if I flicked the go switch

hey Justin heres a real quick video of the crusher crushing dirt lumps.
just fitted battery drill to shaft and had it set on low 0- 400 rpm, it appears to work better at the higher speed but needs conveyors running to take away the crushed dirt as it blocks up with out them running.
the crusher motor is a 1200 rpm unit so I can slow it down on the pot on my power supply box.

heres test #2 , big rock ( hard dirt) may have to change crusher plate to make gap smaller at bottom but first I need my conveyors running so it has a chance to break the lumps.

I think the problem is that the dirt is pilling up on conveyor and dirt isn't going far enough into jaws to be broken down.

I think once the conveyors are running and there is weight ( more dirt) on top of the rocks in the jaws they will be forced down the shute to be crushed.

heres a quick video , let me know if my theory is right?



cheers andy

Your right Andy. The more in the chute the better. Crushers are hungry and need a steady flow of material otherwise single chunks will skip and dance around. That's cool if you can easily adjust jaw distance and crush different grades or size of material.

just a small update.
got tracks and sprocket fitted up. now I have to make some track pads.
also found some large orings that might do the job of drive belts, time will tell.
also had the printer up and running making side rails for conveyor belts to contain any stray material.



cheers andy
