Company needed to obtain pellets suitable for processing into slab zinc from zinc flotation concentrates. 450 tons/day of zinc concentrates are mixed with a binder, recirculated fines, sulfuric acid and water to form 700 ton batches. At the disc pelletizers, water is added to form pellets sized between -4 and 20 mesh. The company installed a TURBO-DRYER® with a gas-fired heating system. It reduced the pellets' moisture content to less than 0.5%. After processing by the TURBO-DRYER®, pellets enter two triple deck vibrating screens. The results were that the preparation and pelletizing system achieved 85% pellet recovery from concentrates to roaster feed bin.
