Grain Mills – Grain Crackers info

The grain mills and grain crackers are fairly simple devices, the hammers spin and smash whatever product is in the hopper until it is small enough to fit through the sieve.
The more work the grain crackers has to do to break the product down small enough to get through the sieve, the longer it will take.
If you are feeding animals, you want to put the grain through the largest sieve – you can to suit both the grain (so it is not all falling through) and also the size of the animals. ie 2.5 mm for smaller chicks, 4 mm for adult chickens and pretty much any size you like for the larger animals such as sheep, pigs, goats horses etc. -For the animals to digest the grain the mill only needs to crack the surface protective layer it does not necessarily have to smash the grain up.
If the grain is dry it will explode better when the hammers hit it and will thus process faster.
If there is too much moisture or oil in the product then it will tend to squash rather than explode when hit (think raw peanut vs cooked).
If the product is squashing then it will absorb some of the energy from the hammers and not break up as easily and thus take more time, being the case with all three grain mills or crackers.
If there is too much oil or moisture in the product then it can actually gum up the hammer section (ie peanut butter.)
So long as the hammers of either grain mills or grain crackers are spinning, then the machine is working properly.
It will be a case of adjusting the sieves for type of product and or required end result :
The manufacturer estimates 60 to 200 kg of product per hour through these machines. 60 kg is for finer sieves and larger product,  200 kg is for just cracking with some product possibly still going through whole, but most cracked using the sieve with the largest holes, so one must select the most suitable sieve among those supplied.
Note: Output varies due to many factors like grain type, moisture content and so on. Additional sieves are $55 each.
