How Does a Moisture Meter for Cotton Work?

By the time an oven dry test is finished, there could be a large change in the moisture content of the rest of your cotton. Plus, oven dry tests can be destructive to the cotton being tested. This is where cotton moisture meters come into play. These devices can provide a fast, quantifiable measurement of the moisture content of your cotton.

DETERMINATION OF MOISTURE CONTENT

Moisture content is given with the relation ×100 − = w w d wb W W W %mc, where mc is expressed on wet basis (W w is wet weight and W d is dry weight). Moisture can be expressed on dry basis ×100 − = d w d wb W W W %mc, this value sometimes being used for particular studies. The conversion mc wb ⇔ mc db is given by following formulae: db

Ball & Rod Mill Density - How Water Impacts Grinding

Density, if you recall is the ratio of ore to water and is measured as a percent of solids in the water. It will control the grind in two ways. It affects retention time and helps distribute the ore through-the mill so each piece of rock will come in contact with the surface of the rods. To maintain a proper balance between these two is critical. What water does is kind of provide a mode of
