Our Founding Father

D. Coyne Callaghan | 1921 – 2017

In 1960 our Dad, D. Coyne Callaghan, started developing first Rollo-Mixer® to mix dairy feed with liquid molasses. The same principle of gentle, uniform blending with or without liquid additives, is the driver behind each of the six rotary drum mixers, blenders and coaters we manufacture today.   Continuous improvements, a commitment to excellence, and direct expertise allow our customers maintain top quality performance in the field.

Family Dedication

Continental Products and the Callaghan family are dedicated to manufacturing and developing specialized, high quality, rotary drum, batch mixing blending and coating equipment.  We are very proud to work for our Dad, as we strive to continue his tradition of friendship, product development, and unrivaled dedication to our customers.
