Why do Sicoma mixers not use cleaning rings on their shafts?

Heavy steel cleaning rings are used by many other manufacturers, but Sicoma refuses to add them because of the damage they do to the concrete. Aggregate gradation is affected detrimentally, reducing strength in unpredictable ways. A properly designed paddle, arm and hub is self-cleaned by the intense mixing action – there are no dead spots and at the end of the day, little or no buildup should be evident on these parts. Better solutions through better engineering and innovation.
