During the demonstration at melvin l.Joseph construction in georgetown, de, a powercrusher pc4 jaw crusher was on site for attendees to examine.
The jaw crusher appeared earlier in broken equipments, because of its simple structure, robust, reliable, easy maintenance and repair and production and construction costs less, therefore, until now still widely available in the roads and bridges, metallurgical, chemical, building materials, electricity, transportation and other industrial sectors, for the crushing compressive strength at 147 ~ 245mpa of various minerals and rocks of coarse, medium, small and fragmented.In recent years, our factory to meet the metallurgical, mining, construction and other industrial sectors broken high strength, high hardness of low carbon ferrochrome needs, specially developed strong jaw crusher.
Dalam pertambangan, proses crushing ini dibagi menjadi beberapa tahapan yaitu primary, secondary dan yang terakhir adalah tahap fine crushing.Jaw crusher sendiri merupakan alat yang digunakan pada tahapan pertama atau primary crushing, yaitu berfungsi menghancurkan batu berukuran besar untuk dijadikan ukuran kecil sehingga bisa diproses ditahap selanjutnya.
