Dang, nice cleanup. That’s going to have a real decent total weight.

Very nice

A few weeks back we went out doing some testing on our largest RC812 crusher. Things did not go so well. When we broke the machine last time, I though in a large rounded rock that we call a green meane a large very dense rock that does not crush well do to the extreme hardness. I broke the bottom end out of the jaw so we thought that was the only problem. So we put it back together with a bulletproof bottom end. We did not check the top end out and we did not realize that bent the shaft on the previous test as well. So now we are going to use a more exotic stress proof material for the main shaft. The crusher worked ok with the bent shaft however it caused the side plates to flex and reduced the stroke of the crusher that slowed down the production. We also did a lot of other tricks that worked quite well.
You can see why we go out testing and testing we want to be ready for the market and have no issues.

Time to fish I guess that's spooky if they crawl up on you .

Looks pretty accurate for the current situation in California, except it should be ticks or some other blood sucking parasite.

Looks like australia

It looks like the mosquitos around interior Alaska 🦟—🦟—🦟

It’s Mormon Crickets.

I wanna go dredging... invite me please !!!! Lol

Cricket Lives Matter. Have they set the fuel tank on fire and tore off all the Keene badges yet?

We had plans to take out our latest RC812 rock crusher and unfortunately, we never made it. So this weekend we trying again. One of the guys that helped us last time " Barry" came by and had to slap me around a bit and reminded me of some things we discussed in our last test session. So we made 3 changes.

We changed the sprockets around on the crusher to speed up the roller 25% faster.

We reduced the lower jaw opening so the rollers would have less load on them.

We are trying out something totally new a large spur or timing gears to keep both rollers powered. Once in a while if a crusher is not adjusted correctly one of the rollers can lock up and not spin and this can cause extra wear and tear on the rollers. Well not with this new design.

So we are looking forward to this test we are taking it out on a real mining operation with a lot of new things. The customer has a large sluice that he is providing and we upgraded the riffle to something more appropriate for the type of ground he is running in. We will be crushing material then feeding it into a gold claimer machine that concentrates the material. The concentrates with then are feed onto a shaker table.

So this should be a lot of work and fun and a great learning experience for all of us. It is always fun when both Patrick and I and some good friends have a chance to go out and get Dirty.
