Boost productivity with automatic mixing

For large jobs, the affordable CM20 continuous mixer achieves higher output than traditional methods and comparable mixers while maintaining a high quality mix. In addition, the CM20 is the first continuous mixer on the market to be rated for a standard 120V circuit so you can plug it in and start mixing anywhere on the site.

The CM20 Continuous Mixer makes it easy to improve your crew’s production rates by automatically mixing pre-blended mortar products. It eliminates the need to manually measure water into the mix. Simply set the water flow rate for your specific material, break bags of material into the hopper, and the system automatically does the rest. You increase productivity, get done sooner and boost your bottom line.
