Mill coolant system design

 · The mill reservoir should be placed close to the mill and use larger-diameter pipe over shorter distances to provide the least change in coolant pressure from the pump to the mill. A rule of thumb with plumbing is to maintain the largest required plumbing diameter as long as possible when carrying coolant to the mill because any reduction in diameter limits flow and pressure at the …
