each kind of different degree of hardness, the viscosity and the humidity all big material carries on thick garrulous, is garrulous and is in broken bits. This kind of crusher stave efficiency is especially high, the energy consumption is small. At present overseas in the roller type breaker, the impact type breaker and in the hammer type breaker design, the manufacture and the application has all made some new progress.Keywords: Crusher developmentEnglish Babbitless (GB) Corporation has made one kind of stave scaled height of burst, the energy consumption low Dragon impact type breaker. This machine series product includes: PS10.05 (rotor is 1 0.5 ), PS10.10 (1 1 ), PS12.13 mm(1.2 1.3 ) three kinds of specifications.mThis company makes this kind of impact type breaker available in stave dolomite, ore and so on silicon nature limestone, but cannot break the humidity and the coherent all very big material. For the material granularity is 65150 .In fact, this machine most suits the stave massive material, does not suit the stave laminated material. The stave product granularity below 40 , productivity is 15150 .mhtThis company has also made the impact type breaker which 13 kinds may reverse. The permission amounts to 380 for the material granularity, productivity surpasses for 600 .htThis company also has produced 6 kinds of specifications type breaker, productivity is 35195 , the product granularity is 650 .t mEnglish Groft Barmac Corporation makes the Rotopactor breaker, is one kind has the unique form three levels of impact type breaker. When stave work, the material enters in the stave cavity by certain acceleration between the rotor and the sidewall, thus has the impact to be staving. The material transportation is delivers in the stave cavity from the hopper after the central divider on the fast revolving rotor. The stave product falls in the dump trough. The stave cavity attrition is very small, but must carry on the special wear-resisting protection to the stave region. The rotor circuit must lining the attire tungsten carbide guidance board, thus stave cavity upside and the base must install the casting 5backing. The rotor skin hardness request is extremely high.

This kind of breaker has three kinds of specifications, the stave mproductivity is 730 tons/hour, 1560 and 30110 .hthtEnglish GEC Corporation makes the Dyad double rotors swinging hammer type breaker, productivity reaches as high as for 1000 .tWest German Hazemag Corporation makes Hazemag impact breaker. Corporation sells the entire Englands quarry from English Peabody Holmes. The APP2030 bulldozer and the APKM1630 intermediate crusher are two kinds of large-scale impact type breakers, presently pays the English quarry use. Two equipment contract prices are 125 pounds (in contract including supplies electric drive equipment, special-purpose speed control equipment and energy recycling installment).At present several hundreds Hazemag impact type breakers have been used in the limestone and other mines. In which majority breakers productivity has all surpassed for 500 .htAmerican Hewitt-Robins Corporation is producing the double rolls type and three rolls type breaker, the impact type breaker and the hammer type breaker. The double rolls type breaker is used in the process load big work, its productivity surpasses for 810 , htthis machine has used the hydraulic pressure crushing roller installment, and the over-load protection spring and the oak rubber tire drive type. This company produces 24 inches 48 inches three rolls both sides coal washing used the breaker, and has the small crushing roller hydraulic unit and the belt pulley drive. Productivity (stave product granularity is when 2 inches) may amount to for 320 .htThe Hewitt-Robins impact type breaker is one kind of high efficiency, big the reduction ratio impact type breaker. Its specification respectively is 36 inches 54 inches 6and 48 inches 66 inches. This machine productivity is decided by the riddle through whole size. When the riddle clear size of opening is 3.5 inches, its productivity may amount to for 900 .htThis company also makes two kinds of specifications the hammer type breakers, namely: 36 inches 32 inches and 48 inches 32 inches, its riddle lattice bar and the spacing all are adjustable.
