Development survey of roller type breaker,impact type breaker and hammer type breaker

The roller type breaker, the impact type breaker and the hammer type breaker application scope is extremely widespread, can to 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.68744

English 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 (1.2 1.3 ) three kinds of specifications.

This 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 65~150 .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 15~150 .

This 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 .

This company also has produced 6 kinds of specifications type breaker, productivity is 35~195 , the product granularity is 6~50 .

English 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 pider 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 backing. The rotor skin hardness request is extremely high. This kind of breaker rotor, available 2 or 3 parts compose two patterns the rotors.

This company produces this kind of breaker series has five kinds of specifications. The actuation power is 75~500 horsepower, productivity may reach as high as for 250 . This kind of breaker drive may carry on the modification; the machine structural style pides into the enclosed type and the opens type.论文网

Croft Corporation recently installed the use the M Ⅲ breaker, which is loaded with the double drives and two 200 horsepower electric motors,its productivity surpasses for 200 . The M Ⅰbreaker is one kind of small breaker, the productivity is 50 .

American Eagle Corporation makes the Maxim multi-cage type breaker, which is used in mixing the material stave. In each kind of cage type breaker, all has by reverse direction revolving (gives material along straight line and center) 2, 4 or 6 concentric cage rooms. Each cage room all has a row of impact stave stick. Stave product granularity from 20 to 200 meshes. This kind of breaker has three kinds of specifications, the stave productivity is 7~30 tons/hour, 15~60 and 30~110 .

English GEC Corporation makes the Dyad double rotors swinging hammer type breaker, productivity reaches as high as for 1000 .

West German Hazemag Corporation makes Hazemag impact breaker. Corporation sells the entire England's 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).
