Industrial materials can be efficiently pan granulated by grinding the material to 95% minus 150 mesh, feeding this to a pan in conjunction with 1 to 15% seed materials and applying binder solution such that the free moisture content of the green ball is between 8-13% by weight of the feedstock. The granules build up on the seed to a desired size range, say -5 to +8 mesh, in an onion skin manner. Product is sent preferably to a fluid bed dryer for drying. The productivity and classification is very high with yields up to 95% for two mesh size ranges, such as -5 to +8 mesh.
