As for the processing materials, Zenith's track mounted mobile crusher is widely used to deal with various metal and nonmetal ores, including the cement, abrasive material, glass, construction material, machine-made sand, metallurgy, etc.With high intensity and easy transportation, our track mounted mobile crushing station is widely applied in the road & bridge construction, metallurgy, quarry mining and powder pulverizing, etc. According to our customers, the track mounted mobile crushing station has significantly improve the crushing the capacity of their quarries. It is suitable for medium and fine crushing of different hardness of varied ore and rock, such as iron ore, nonferrous ore, diamond, bauxite, quartz sand, corundum, basalt and other aggregate material’ medium and fine crushing.

So prepared, the stone A of the quarry is ready for the application of the machine of the invention so that finished quarrying operations to produce nal shapes may be made.Reference will rst be made to Figure 6 of the drawings, wherein there is shown a section of bed stone, designated A, ready to be quarried by the machine of the invention, the said section having been out horizontally to provide the straight upper face and also cut vertically to provide the outer straight face C.

The modular screening elements 110 are normally alternately placed so that the neighboring screen elements always will be at different heights. 1. 1 schematically shows a prior art screening deck 100 in a vibrating screen for screening of crushed stones, gravel or the like comprising exchangeable modular screening elements 110 and transverse carriers 120. The transverse carriers 120 are fastened by bolting, welding or other suitable fastening means to cross members (not shown) arranged in a vibrating screen mechanism. The longitudinal direction of the screening deck is also the travelling direction for the material, i. The modular screening elements 110 differ in height to improve the screening of crushed stones or gravel. In a surface 150 of the modular screening element 110, through-holes H have been provided for fractionating crushed stone and gravel into fractions of stones with different sizes.FIG. The modular screening elements 110 have snap locks 140, which interact with the elongated stanchions 130 a, 130 b for fastening the screening elements to the transverse carriers 120. Each carrier 120 has two parallel, elongated stanchions 130 a, 130 b. stones or gravel, on the vibrating screen.e. A longitudinal direction of the screening deck is indicated with an arrow A in FIG.
