    The motor coupler is just a 5/8" diameter Aluminum rod with a 1/4" bore through it and a couple of set screws to fasten it to the stepper motor shaft and the ACME rod lead screw. Note that the dimension shown on the drawing for the length of the motor coupler is incorrect- it should be 1 1/4" long.

    Crude grinding solutions. There are multiple types of wolfram grinders. For example, you can just use normal grinding tools like a rotating rock grinder. As the rock rotates, you just let the tip of your tungsten rod touch it. You should control the position of the rod to the abrasive to get the ideal grind angle.

    Jan 15, 2010· I received a NutriMill for Christmas last year, and it was an investment we have not regretted. Previously, I had been "borrowing" a mill from a generous friend; we would split a 50# bucket of wheat, and she'd grind it for me as-needed (this is a GREAT option if you can find a friend to split the cost of a good mill — unfortunately, my friend moved away and took her mill with her).

    Gelatinization occurs by mechanical means such as grinding, pressure, and by hot water. Soft feed at an environmental temperature of 25°C can be brought to a temperature of 85°C by the addition of 4 to 6 percent moisture from steam. Frictional heat due to passage of feed through the pellet mill adds 2 or 3 degrees of temperature.
