Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent.
Plus de détails5.1. A primary gyratory crusher was required to crush iron ore at the rate of 3000 t/h. The largest size of the run-of-mine ore was 1000 mm. The required product size was less than 162 mm. Manufacturer's data indicated that the nearest size of gyratory crusher would be 1370 mm × 1880 mm with a cone angle of 18°.
Plus de détailsGyratory Crushers. The primary rock breaker most commonly used in large plants is the gyratory crusher, of which a typical section is shown in Fig. 5. It consists essentially of a gyrating crushing head (521) working inside a crushing bowl (522) which is fixed to the frame (501).
Plus de détailsLarge receiving opening per dollar of investment. Shape of receiving opening favourable for blocky feed. This, plus point 1, give the jaw a definite advantage over the gyratory, except in the very large sizes, for handling rock of massive formation. The jaw crusher is more easily adjusted, to compensate for wear of liners.
Plus de détailsgyratory crusher is shown in Fig. 28. It is also available as a hydrau- lically supported unit. Housing Frames or Shells. The crusher frames or shells of large gyratory crushers are made of cast steel. The original crushers used cast iron frames, a few of which are still used in the smaller crusher sizes.
Plus de détailsJaw crusher can crush high moisture, viscous ore, and not easily blocked. Generally, the large scale mining process company more use the gyratory crusher, the small-sized mining process plant and quarry plant more to adopt jaw crusher. Dust The coarse jaw crusher has a large amount of dust emission, the rotary crusher is much better.
Plus de détailsIn stone quarries or in very "boney" gravel pits, large material usually is reduced in size by either a jaw (Figure 5- 7) or a gyratory crusher. Both types are compression crushers. Although economical, they have the tendency to create thin, elongated particles. Particle shapes sometimes may be a problem for Producers of hot mix asphalt.
Plus de détailsThe practical use of impact crushers is limited to soft materials, such as phosphate, gypsum, weathered shale's, etc. Impact crushers cannot handle as large a top sized material as jaw, or gyratory, crushers can; however, impact crushers can make a finer sized product. Autogenous Crusher
Plus de détails4.Owing to relative higher processing capacity, large-scale concentrator is generally use gyratory crusher as the primary coarse crushing equipment. Besides, gyratory crusher has relative high reduction ratio, which is up to 6-9.5, individual cases to 13.5. However, small-scale concentrator and quarry is generally use jaw crusher as primary ...
Plus de détailsBesides, the super beam design is adopted to increase inlet size and crushing efficiency. The ore outlet control system adopts hydraulic adjustment method to compensate for wear liner and reduce maintenance cost. 4.Flexible adjustment and convenient maintenance. Adjusting the eccentric sleeve can change processing capacity of gyratory crusher ...
