Hammermill Crushers McLanahan

Reduction ratio is often measured by dividing the F80 by the P80. The F80 is the particle size where 80% of the feed material is smaller than that size. The P80 represents a particle size where 80% of the product is smaller. Reduction ratios will vary with each application within each family of Hammermills and by the amount of applied energy.

Silver may be used as an investment like other precious metals.It has been regarded as a form of money and store of value for more than 4,000 years, although it lost its role as legal tender in developed countries when the use of the silver standard came to a final end in 1935. Some countries mint bullion and collector coins, however, such as the American Silver Eagle with nominal face values.
