Hayes & Stolz Ind. Mfg. Co. uses a combination of creativity, state-of-the-art technology, and expertise to design and produce a line of mixing equipment that is unsurpassed in efficiency, fast mix times, and durability.
	With over 60 years of experience as a mixer manufacturer, Hayes & Stolz has invested countless hours in the development and testing of various ribbon and paddle mixer configurations in an ongoing effort to deliver the most efficient mixers possible. The performance of mixers currently provided by Hayes & Stolz has been thoroughly verified through rigorous testing using the latest testing equipment and methods.
With the knowledge gained from this extensive testing, Hayes & Stolz has developed a proprietary computer program to assist in the design of its mixers. Each type of mixer has numerous variables that must be brought into balance to achieve homogenous mixing. Using the computer program, Hayes & Stolz is able to design both ribbon and paddle type mixers with the precise balance of shaft speeds, agitator component pitch, component width and spacing, along with width-to-length body ratios in order to deliver maximized performance.

Ribbon and paddle mixers, both single and twin shaft designs, are available for testing of specific products and/or applications. Tests can be conducted at the Hayes & Stolz test lab, or a mixer can be shipped to the customer's facility. Contact Hayes & Stolz to arrange for testing of your application.

"Coefficient of variation" (Cv) is the measurement of variability of a trace ingredient in relation to the mean (or average) and is used to compare relative dispersions. For most applications, a Cv of 10 or less denotes homogenous mixing has been achieved.

Homogeneous mixing, measured as coefficient of varation (Cv) of less than 10, can be achieved in as little as two minutes in the Hayes & Stolz Single Shaft ribbon Mixers, and in as little as three minutes in the Hayes & Stolz Single Shaft Paddle Mixers.

Hayes & Stolz Twin Shaft "TR" (Twin Ribbon) and "TP" (Twin Paddle) Counterpoise Horizontal Mixers, can acheive Cv's of less than 10 in thirty seconds.
