Quarrying Stone Crusher Production Line

Algeria quarrying is very prosperous, the economy plays an important role. A lot of ore and stone mining and processing resources are to a certain size, the finished product can be used in construction, paving, water conservancy and other projects. Crushing could be carried out in three or four stages, primary (initial stage), secondary (second stage), tertiary (third stage) and, in some quarries, a quaternary (fourth stage). Crushed rock, or item, is transported along the procedure line on conveyor belts or down chutes.The principal crusher is fed through a chute and vibrating feeder. The base in the feeder is produced of steel "grizzly" bars and it's right here that the initial screening operation is really carried out. Fine material and dust produced by the blast, in addition to any remaining subsoil or weathered rock in the best from the quarry face, drops by means of the bars onto a separate conveyor belt and onto a stockpile. This screened material is known as scalpings and is used as rock fill.

Primary crushing is normally by a jaw crusher consisting of a heavy metal plate which moves backwards and forwards against a fixed plate (these are the "jaws").Secondary, tertiary and quaternary crushers are usually gyratory, or cone, crushers. These operate on the principle of a steel mantle mounted on an eccentric bearing and vertical shaft assembly. Rotation on the eccentric assembly tends to make the mantle gyrate within a static outer concave. There is a gap between the mantle and also the concave. The shape of the gap is tapered towards the base. Because the mantle gyrates inside the concave, the gap between it along with the concave at anybody point opens and closes on every gyration, this produces the needed crushing action. Stone is fed in in the prime and crushed solution falls out from the bottom from the cone. The mantle might be raised or lowered within the concave, allowing the gap, and consequently the size on the crushed item, to become varied to a restricted degree. If the crusher is jammed by a stray bit of steel, e.g., a digger bucket tooth, the mantle automatically moves down to clear the obstruction.
