A large, international manufacturer of dry cell batteries approached Quadro to help them with the manufacture of their battery products. The battery employed several powder mixtures of Teflon, Carbon Black powder and 1/8" pieces of Graphite. The customer was getting 30% - 40% of the product below 60 mesh USS, by running a single-pass through a Hammermill and two passes through the Comil®. Heat generation in the Hammermill caused blinding of the screen which slowed down production of the batteries. The customer wanted to eliminate the Hammermill stage. The required capacity rate was 13 lbs/hr.
