Split drum mixer: The drum, rotating on a horizontal axis, separates into two halves, allowing the concrete to be discharged cleanly and rapidly. No blades are required since cohesion to the top and bottom of the drum and cleats provide adequate charging and mixing. Typical capacity is 2.5 CY and provides a short mixing cycle and rapid discharge.
By stopping concrete build-up in the first place, DrumBlaster eliminates workplace risks of manually removing the build-up from inside the drum. It is a recognised global safety principle that it is far better to eliminate risks rather than trying to minimise them. Products/Services
