The feed opening, discharge settings, horsepower and cost of the machine are all considerations when determining what concrete crusher to use. The feed opening is critical because chunks of material must be small enough to fit in. If they're not, one must prepare the material to fit into the feed opening with hydraulic hammers or pulverizers.

Abstract. Charnockite, a quartzfeldspathic rock containing orthopyroxene, is an important component of high-grade, deep-crustal terrains. The origin of charnockite by both igneous and metamorphic processes, not yet clearly defined, has major bearing on the evolution of continents.

Typically, the minimum setting on most primary crushers will be about 4 to 6 inches, as noted above. Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types. 2. Secondary Crushing.
