Color photographic print depicting grinding mills at the Champion Spark Plug Co.
Caption reads: All Champion ceramic plants use the same modern, efficient manufacturing process illustrated in these pictures of the Detroit operation.
The raw materials are carefully weighed, water is added, and the mixture is ground for several hours in the mills, as pictured here. Several mill changes are then blended in large mixing tanks to form a batch for spray drying. Extensive quality control checks are made on each batch before releasing to production.
