I have finally figured out how to apply my Minn Kota Trolling motor to my JSP Maltmill.
Per Minn Kota, the motor is rated at 1000rpm at it's highest speed. It'll draw 25 Amps under load. So, basically this means it is a .4 Hp motor with super high torque (value unknown). This motor is a 4 speed motor so, by quartering the RPM I deduce that at speed 1 it runs 250 rpm.
After doing some calculations I have settled on a couple combos.
At a 3.125:1.00 speed reduction ratio I get 80rpm at speed 1 and 317rpm at speed 4.
At 2:1 I get 121rpm over 487rpm.
JSP suggests no higher than 300rpm for the lo0gevity of the mill. Furthermore, a hand cranked crush is estimated at 60 to 100rpm and is the most delicate on the grain husk.
What ratio would you shoot for?
Slow rpm's and a longer crush time per pound (noting that it's automated now).
or
Higher rpm's with a slight sacrifice in crush quality but, gettin' the job done quickly.
I am inclined to go for the slower range favoring a better crush but would like to hear what the community has to say.
