solid rock: limestone and hard rock or crushed volcanic rock. this is 'crushed' sand because the grains are pointed. • recycled materials: often of industrial origin, from demolition, recycled concrete, railway ballast, etc. step 2: extraction: extraction is a key phase during production from solid rock, particularly because strategic choices,
tertiary crushers are commonly used in the aggregates industry for final particle shaping to increase cubicity, and to produce a product size beyond what is capable from a primary or secondary. this stage of crushing is typically accomplished using a vertical shaft impactor or cage mill. rock & aggregate crushing equipment
with rock-crushers, stamp-milling becomes automatic, from the dumping of the ore into the crusher. there is another advantage in the use of crushers instead of hand-spalling, which is especially evident in the case of gold- quartz mines, where the gold occurs in masses, or bunches of considerable size and value, spread through the quartz, as, for example, at some of the mines at grass valley, in california.
