The portable Asphalt/Concrete Mixers are ideal for sample or small batch mixing in just about any setting. The enameled-steel mixer holds a utility bucket securely in place. As the bucket rotates at 60rpm, a stationary Mixing Paddle scrapes sides and bottom of the bucket to ensure thorough mixing. All 115V/60Hz mixers are supplied with a 1/2hp motor, On/Off switch, fuse protection, and an 8ft cord with three-prong plug. For 230V/50Hz mixer, add "F" to model number suffix. The 10 gallon "F" model is supplied with a 1hp motor.
