The hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone. Thus far we have described machines which do a portion of their work by impact, but the only machine described in which this action plays an important role was the sledging roll type and …

Jaw Crushers; Cone Crushers; Typically, the initial crushing stage is completed using either gyratory crushers or jaw crushers. It is often the case that there will be only one crusher installed, and this will be referred to as the primary crusher. Cone crushers are more often used for 2nd, 3rd & 4th stage crushing steps (although not always).

Today, the extraction of beryllium begins with the mining of raw materials (bertrandite ore and/or beryl ore). Beryl ore is melted in industrial furnaces, solidified and crushed, then treated with sulfuric acid to produce a water-soluble sulfate. Bertrandite ore is crushed, made into slurry and treated with sulfuric acid to form a sulfate.
