processing, throughput is a term used to express the expected time in hours it will take for tons of rock to grind to the target size in a ball mill. Mill throughput ranges from good throughput at 315 to 300 tons per hour (TPH), to bad throughput from less than 300 TPH to 250 TPH, to really bad throughput, which is anything less than 250 TPH.
