Garnet removal

Winks · Newbie

I am very interested in the answer to this question also. Shovelling sucks, but so does wasted investment in something that does not live up to its promise.

I think I am getting good results with an air operated diaphragm pump, but you must use a screen on the suction line wand. Still very manual, but easier than shoveling.
The pump is 1" and I use 3/4" tube for the suction line.
I use 2 settling tubs in series to collect the garnet, with the water then flowing back into the catcher tank.

Try this. Very inexpsnsive and works great.

Normally, there are two types:

1, workshop with crane, it will be a jumg bag. The removal tank with suction from waterjet tank, water over flow into watertank again, while sullage will go down into the removal tank bottom.

Some have to do is that we have to install some pipes with small holes for suction inside cutting table tank.

2, workshop without crane, it will be the same theory.But the sullage have to manual operation after the removl tank is full.

Any other good suggestions?

I know Omax has a SRS (solid removal system) that works with pipes running along the bottom of the tank to suck the garnet from the tank through a pipe outside and into a seperate hopper and then the water is returned to the tank from the hopper and th garnet settles in the additional hopper. There is a good picture of the blades on OMax.com

We have the local Septic Cleaning Company come with their Pumper Truck once a year and they suck it all out.

I built my own using a gas powered pressure washer (4500 psi) to create a venturi effect in a wand. Discharges into a 2000 lb scrap bin hopper, water overflows back to the waterjet holding tank, abrasive stays in the bin. Works great i can usually remove about 2000lbs in an hour. I spent less than 1000.00 on off the shelf parts (pressure washer, bin, hoses, tubing, valve, etc.) the rest of it I made with the waterjet and welded.

We actually use a ward 1, I recycle appx 60 lbs an hour and the particles that are too small to cut with go into a dump hopper.
Works well.

Sorry double post.

It has more than paid for itself. We have thrown away our shovels since we bought it, appx 5 years ago.( I did a few common sense modifications to it along the way, but engineers are not working in a practical world :P ) .

And, No. I have no vested interest in telling you this.

we just got the BART and i got to run it yesterday. it looks like we are done shoveling now. the nice thing was we were still running and cleaning. there are pros and cons to this and the setups in the tank. im not sure if some people just throw it in the tank and let it be but i was working it around the tank.

We have a Waterveyor that we purchased with the Mach3 Flow Waterjet, back in March 2011. It works pretty good.

We went to Clean the Main Cutting tank a few months ago and it was Mostly clean (about 20% full), after about 1800 hours on the High Pressure Pump.

Do you remember the cost? We just got a quote of $5,000 to pump out the sludge and haul it away. The tank is 12 feet x 5 feet.

We have about 11 waterjets in house with various garnet removal systems. The one that seems to work the best is the ward jet. It is not anything complicated and really could easily be built in house, its only piping running along the bottom of the tank. The sludge/water is pumped out through the series of pipes into a dump hopper which in turn overflows back into the tank, settling is the key. We use this general setup on all our machines, some have pits under them with no tank or plumbing, just a pump that continues to run through the hopper. We use 1-1/2" diaphram pumps and run them low throttle to get the best settling effect. Stirring the tanks using the jet can sometimes fill the hoppers within 30 min if theres alot in the tank. We also have a Siemens 1500mm filter press that helps keep up and reduce the weight going into the dumpster.
