How The Mini Milling Machine Works. As the Milling Machine grinds the nuts, gently squeeze the oil dispenser to drizzle oil into the Nut Bin. Every 10 to 15 seconds, spin the Nut Guide to mix and guide the nuts into the Nut Guider. The Nut Butter will dispense into the Nut Butter Container. You can even make roasted nut butter.
