Learn More29/05/2010 · Here is another important note: Most mixers’ batch capacities are actually about 67 percent (or two-thirds) their total volume. Therefore, if a plant needs to batch 1 yard of concrete, the mixer’s total volume would need to be 1.5 cubic yards. It is important to know how a mixer is rated, either by batch volume or total volume.
