Every part of the system must be working properly to produce quality feed. You must carefully calibrate the mill, analyze samples of mixed feed, and frequently check the system to produce quality swine feed. Batch Mixing Systems Batch systems take more time but generally are more accurate because each ingredient is weighed.
Vertical mixers are more popular than horizontal mixers because they take less space.
Horizontal mixers typically provide a better mix and have a shorter mixing time. Some stationary systems combine both a horizontal mixer for combining ingredients used in small amounts and a vertical mixer for mixing the complete feed. The mixing accuracy of a horizontal mixer is because of its mixing action. Both will provide a good mix, but the ribbon provides a more uniform final mix. Horizontal mill with ribbon mixing.
