Mobile Crusher:The most important Equipment needed for Quarry

Although in general a quarry is a type of open surface working from which virgin rock or minerals are extracted, each quarry is very different and will use different types of quarry equipment. The design and general running operation of a quarry depends on the type of rock being extracted, the general environment surrounding the quarry, the size of the quarry and the geography and geology of the general area.

Basically there are three different types of primary crushing units to choose from. Mobile crushers are manufactured and delivered as jaw, impactor gyratory crusher. The gyratory crusher at first was implemented for secondary crushing, but will be soon available for primary crushing too. Depending on the pit demands the engine can be diesel powered and reach up to 645 KW or can also be electric powered. The travel speed of the track gear is approximately 1 km/h and the mobile crushing units are able to incline 20° or 35%. The throughput for jaw crushers can range up to 1800 Mg/h depending on the feed material. The weight of mobile crushers varies from about 60 Mg to more than 200 Mg. Normally jaw crushers are equipped with a vibrating feeder, a bypass to keep small fractions away from the crushing process, the crusher itself, and a main conveyor. Depending on the manufacturer and the individual needs more equipment can be ordered. For example, screens to be placed in the bypass can be bought to scalp out waste material at an early stage of the process. Unnecessary haulage into further processes is thereby avoided. Using screens in the bypass only makes sense if there is a second discharge conveyor installed. In addition to this linking adapter for the mobile conveying system, money could be spent for such things as: dust encapsulating, magnetic separator, hydraulic hammer, driver cabin, several supporting stands, if needed. According to the needs of a mobile conveying system an electric generator must be bought too, because power supplied to the conveyor belts are normally comes from the mobile crusher units.
