My job working at an aggregate mine (rock quary) was running this plant. The purpose of this plant was to wash rock so that it would be suitable for concrete in roadways. Mostly I made sure the machinery wasn't tearing itself up and cleaned up all the rock that would spill.

I shoveled some of spilled material or used a hose on the slurry that would spill all over the place. The slurry pump system had problems. The conveyor running to the left had one inch stone. The rock in the middle I believe is 3/8 inches. The conveyor running to the left horizontaly had small chips. The conveyor running on an incline on the left had sand on it.

The material was loaded into the bin you see way in the back. From there it would be "washed" in the log washer which you can't see in this photo. Then the washed rock would ride on an inclined conveyor to the screen. The screen is the highest part of the plant. You can see the rows of water sprays on top of it in this picture. The chute in There are chutes in front of the screen that divert each size of material to it's proper conveyor. The slurry of fines from the logwasher and screen went to the sediment screw.

The white building on the left housed all the switches for the plant. One of them had the nickname of the one armed bandit. I had to stand off to the side while throwing the switch because sometimes those boxes would explode after being switched on.

This is the log washer that you couldn't see in the first picture. The barings for it had to be greased once a day. I think it was fifty pumps with a grease gun each. It was a manual grease gun. You can see that there are tires on the log washer. The wash plant could be taken appart and moved to other opperations. I don't think this was done. The crusher and pit conveyors were moved while I was working there. I had fun cutting all the bolts that kept sections of the crusher together.

Here is a closer view of the screen. Changing screens was not easy.

It's not a great photo of the sediment screw. All the fines washed from the rock in the log washer and screen would go here. The screw would separate the usable sand from material that is much like dust. The unusable slurry was pumped to a nearby creek. All of the water for the wash plant was pumped from the pit. A daily task was to turn that pump off an on.

This Conveyor took rocks 3/8 inches or less to the pile on the right. The green truck had a touchy stick shift. I managed it all right. It had more than 400,000 miles on it.

This is the water truck used to keep dust controled at the quarry. In front of it is a skid loader (bobcat). I used it to clean up rocks that would spill at the transfers of the conveyors. I got it stuck once a slurry pond that's located behind the screen.

Lastly, this is a control room for the plant. The switch for the log washer hand a lever that had to be pulled down then thrown up for it to start up. This was nicknamed the one armed bandit, since the attached box was known to sometimes explode. I stood on the other side of the box when throwing the switch. It was a good place to go when it rained.
