Figures shown are examples at continuous feed and manufacturer-recommended water ratios. Actual output varies with material temperature, feed rate, and desired slump — always verify consistency at startup and adjust the water flow valve to suit. Bag brands shown are for reference only; the Spin Max works with virtually any pre-blended bagged material.
