If the facility uses dry process kilns, this moisture is usually reduced to less than 1 percent before or during grinding. Drying alone can be accomplished in impact dryers, drum dryers, paddle-equipped rapid dryers, air separators, or autogenous mills. However, drying can also be accomplished during grinding in ball-and-tube mills or roller
Operating control of dilution water in SAG and ball mills. Operating control of filtration, dewatering, drying and pelletizing processes. Monitoring the moisture content of ores regarding an upper limit, in ship loading operations. This stone outlines the application of an on-line moisture analyzer in a bauxite ore processing plant.
• Dry stone has little or no likelihood of developing new cracks, checks, or splits. • Dry stone (below 22% MC) will not decay, mold, mildew, or stain. At lower MC levels, there is not enough moisture for the fungi that cause decay, mildew, and so on to grow. • Dry stone is much lighter in weight than wet wood. For many species, dry stone is
Excessive moisture in pine creates problems. It causes warps, cracks, splits and twists. It can cause glue bonds to fail. Wet pine won't accept a finish. If you're concerned that your pine may not be dry enough, there's a fool-proof way to test it.

Kiln drying is a standard practice in stone production mills and serves to efficiently bring green lumber moisture levels down to “workable” range–moisture content levels that will not end in the myriad of problems that can be caused by excess moisture levels in wood.. These problems include warping and twisting in dimensional lumber, binding or kicking during machining, buckling or
Too high moisture content in your sawdust will make your stone pellets production failed, and then the stone pellets or stone briquette will be in low density and easy to be broken. Our airflow sawdust dyer makes a great compliment for use with a small stone hammer mill and stone pellet mill. Airflow Sawdust Dryer Introduction
Moisture content sampling at the planer mill is the point in the process where the most accurate and greatest quantity of information can be gathered. Many of the larger softwood mills employ in-line moisture meters to monitor the MC of every piece of lumber processed. If well calibrated and maintained, such instruments can provide
A portion of the wort is analyzed for specific gravity. This value determines the amount of solids that can be extracted from grain. Dry basis results remove the influence of malt moisture from the extract calculation. For example, an 80 percent dry basis extract of a malt with 5 percent moisture would have a 76 percent as-is extract.
