Tech Tip: How Water Quality Affects Coolant Performance

Factors that affect water quality are water hardness, pH, and the presence of chlorides, sulfates, and lead [2]. Generally speaking, hard water is the amount of calcium and magnesium salts, expressed in milligrams of calcium carbonate (CaCO3) per liter of water (ppm). The ideal hardness levels for glass working coolant are between 80 to 110 ppm.

Scrubber Basics - Engineering ToolBox

Water with chemicals are sprayed with high pressure through nozzles into the air flow. Some of the water evaporates, especially if the process-air is hot, and disappear with the exhaust. Water droplets are separated from the exhaust and re-circulated back to the water reservoir. Evaporated water is replaced by fresh water and chemicals.

Effect of Water & Density on Grinding Mill

The bad side of the water is that it takes up space. The more water that is added, the faster the ore will go through the mill. This means the time it has to be ground will be reduced and a poor grind will result. At the other extreme, if not enough water is used, the ore will not be able to flow through the mill.
