Guesses on this pic?

Any guesses on what in the world we're doing in this picture? You may have never seen a hopper bottom being used for this.

Loading up dehydrated, granulated airline bathroom effluent to take to the landfill. Nasty work, but somebody's gotta do it.

Road Salt?

Treated seed going........... back? I'm looking for the tractor, but all I see are pallets of totes stacked up.

Not sure what's in your bag, but at the company I worked we used this type of bags and without something to catch the over flow I don't see how you can control the flow once the bottom is opened and I don't expect the elevator is fast enough to keep up. Just my thoughts.

The bags look like some I have I have in one of my warehouses, they hold plastic resin.

Looks almost liquid.

Smurf food

CaCl road salt is my guess also. Especially as the surrounding snow is kinda weak. Jim

Using a hopper bottom for a seed tender ?
We do that every year for fragile field pea seed. We clean seed directly into the hopper bottom where it stays until transfered to the drills at seeding time, using a 40 ft brush auger with magnetic clutch on the PTO drive. Works great to fill 30 ft of 750 drills with minimum handling of the seeds

using it to spread salt down south?

It's ice melt or salt. I buy it in 2000# totes, similar to seed beans or many other products. I put 30 tons in my hopper bottom yesterday (used for corn and beans during harvest). I was having a hard time filling up our salt spreader trucks fast enough so I came up with this. A couple of the trucks are so tall that a forklift can't lift the tote high enough to dump straight in the spreader body. We load the trailer with this conveyor with a honda engine on it, then turn it around and put the other end under the semi to fill the trucks. This product is a lot higher quality than regular road salt. As of right now I can't buy the good product in bulk easily around here. Plus the backhoes are tied up pushing larger snow pushers and don't have time to stop and load trucks out of a bulk pile anyway. Luckily we've had lots of snow and cold temp's around here! I'm sure lots of people are getting a chuckle out of my hopper bottom, ice melt loader setup! About forgot, on the spout, they don't want these bags returned for some reason so I cut the first string to drop the spout. Then I just cut a "T" in it until I get the right amount of flow. Will load a ton in 90 seconds, closer to a minute if you really push it.

Potassium and Sodium Chloride with a little Magnesium Cl in there as the jumpstarter I believe.

Looks like good use of your equipment. Its amazing all the things those trailers can be used for. Heard of guys hauing landscape rock on back runs with them. Also heard of them hauling apples and other type fruits and vegetables that don't need refrigeration and trailers are running in warm climate. Some damage, but more cost effective than crating the product in the field.

They look like solid bags. I wish I could get them. One time I had two consecutive fertilizer bags tear apart as I was trying to load the spreader so I had to climb in and dig them out.

You probably don't have a very big pile in the hoppers when you're at legal weight. What's it like to get back out?

When I first saw the pic I thought it was seed beans. I used to haul bulk seed beans from the seed plant to a dealer that way. Jim

One summer out west I saw hot asphalt hauled in hopper bottoms. Open a bottom door let it pile up then drive ahead slowly. The paver machine would scoop the stream up spread it out and lay it down. Mark

Hauled rock salt from mines in Hutchinson, KS to MODOT road barns in a hopper bottom. Open em up and drive to unload. Loader would scoop it up and put in barns. Also hauled river sand from Arkansas River near Tulsa to KC, MO to Pavestone. One time even hauled pelletized poultry poop to a certified organic farm out in western KS. Hauled all kinds of feed ingredients, and sometimes even grain off of farms. Mark

Comes out pretty easy. Just have to make sure and not overload the conveyor. We found that out the hard way. I usually put 30 tons in and there was A LOT of room still to go. I thought that would be enough and not push our luck. I never pull it down the road loaded with ice melt. It just sits in this parking lot.
