    Can someone tell me how much one yard of rock salt weighs? Been online trying to find conversion charts with no luck.

    I believe its right around 2,200 pounds per yard but you will get a million answers to this question.

    Ho hum halite

    Halite nominally wieghs 94 pounds per cubic foot broken and sieved.

    And before anyone gets their shorts in a knot,
    the weight is dependent on many factors.

    with this reason being primary- screening to 30 mesh to scalp fines on the second cut,

    Including and not limited to:

    1. salt seam
    2. dome halite salt(which is older in geologic age)

    a. salt fines which may add 20-30 percent to the net wieght of Halite.
    after processing(due to shattering of the crystaline structure of the Halite from high explosives). Transportation distance underground to processing and then rehandling prior to point of sale via trucking or rail transport adding to salt fines in product.

    3. solar salt farm location and harvest schedule.
    4. final seive size prior to stock piling
    a. handling and rehandlling of product.
    5. transportation distance

    Solar salt is harder and much more dense and easier to use.

    The mines final sieve size after crushing determines the amount of dust that is inherent in mined Halite so that is something to consider where solar salt does not have this issue.

    You cannot rely on a normal wieght for halite due to the salt fines and that is the normal scheme of things :rolleyes:

    Salt weight per cubic foot ASTM spec D 632 approx 80 lbs
    Salt weight per Cubic Yard ASTM spec D 632 approx 2160 lbs

    I can confirm the 80/cu ft since my 5 cu ft spreader holds 400 lbs. :drinkup:

    Halite wieght



    A one billion US dollar business not counting the trickle down
    effect to everyone else involved.

    All that, and we can use any grade stone or gravel sand
    at a lower cost per ton, and not cause surface water
    pollution in creeks and streams with chlorides that equal
    the salinity of ocean water; which is 3 percent sodium chloride
    depending on the depth and global location of the sea water.

    Honestly it really depends on exactly what material is on hand and how damp it is. On paper calculations are great but it's impossible to say what you get EVERY time. Places run through thousands of tons of salt a week. Typically I go by 1-1.2 ton per yd from my one fill up spot. It's usually exact on the scale between there. BUT lately it's been light. I weighed out 2 yards the other day for $145 at $95 per ton. I mentioned it to my buddie and he noticed the same thing. I usually get 3 or so but that was a quick top off. My guys have been running this week so I really haven't been watching the tickets.

    check with the source

    Usually whoever is mining the salt has tested it for it's weight. sometimes it is in square foot/pounds so you have to do the conversion, Treated salt will weigh more due to how wet it still is from treating and how much solids the treatment contains

    Thank You Very Mulch for the Break down.....Im going with 2162 lbs per yard...Salt weighs a little more the closer you get to the Canadian Border.....:salute:

    So I can't figure out if one ton of salt weighs more or 2000 lbs of salt way more???

    Coming from you I am not sure if that is a serious question.:laughing:

    How much do you think the 80lb bags I buy weigh !! (jk)

    A yard of salt will probably fluctuate because of moisture content but I would agree around 2200lbs

    It depends on moister content- how fine it has been milled the finer the more denser and the more it weighs. I use 2200 to 2300 lbs per cubic yard gets me pretty close
