The Mechanical Mixer has a moderate speed requirement and a moderate stress requirement. If you are powering the mixer with waterwheels, the speed will need to be increased by using two different sized cogs. Attach the large cog to the shaft coming from the waterwheel, and attach a small cog to the large cog. This will increase the speed of rotation enough to run the Mechanical Mixer.
Place a Basin two blocks below the Mixer. The mixing blade should be between the Mixer and the Basin. When a valid recipe is inserted by throwing the ingredients in the Mixer, the Mixer will automatically engage and combine the ingredients.
