Has anyone out there made a small scale feed grinder-mixer for making their own feed and saving tons of money in the process? From pricing feed ingredients and having a easy supply of field corn costing $4.00 a bushel all around me,if you grind and mix your own the savings are close to 1/2 the cost of custom made and bagged rations. 70% of an 18% Grower rations weight is corn,,Chick Developer from Hubbard ranges in price here from $11.50 to $15.00 a 50 pound bag. 35 pounds of this ration is corn,and at .07 cents a pound for corn based on a $4.00 a bushel buying price,this is $2.45 worth used in a 50 pound bag. There is not another $9.05-$12.55 imput cost for the added supplement to get the protein level to 18%,, So I bought this little gem, It will grind or crack a 5 gal bucket of corn in about a minute.I want to make this a stationary set up,and incorperate a mixing tank where all added supplements can be mixed with the cracked corn and then store the feed as it is being used. Does anyone else grind-mix their own feed? Do you have a set up to mix and store the feed,as in a large scale grinder? I'm looking for possible solutions for this aspect,from something the size of a 55 gallon drum,to a 300 gallon unused-new fuel tank.I would need a cone bottom on it,and an auger going thru the middle to get the cracked grain to the top,and then out so it can be mixed,just as in larger grinders.Or I have considered using a small concrete mixer framework,only adding a larger barrel to hold more. If any mechanical gurus are out here,and knows how a large grinder works and can help with ideas,please advise.
