Astec offers multiple choices in Horizontal Reversing Mixers. The BMH Rollmaster is a heavy-duty, high-capacity reversing drum mixer that does not tilt. It rotates forward at full speed for charging and mixing and reverses rotation at variable speed for discharging. Mounted on solid urethane tires, the drum rotates with less noise and vibration than any other mixer on the market. Costly ring gears and gear head motors are eliminated. The blade shovel system provides efficient charging, mixing and discharging, as well as easy cleaning.
