201611 Currently, the dimensions of the largest Blake-type jaw crusher in use are 1600 mm × 2514 mm with motor ratings of 250–300 kW. Crushers of this size are manufactured by Locomo, (Metso) and others. The Metso crusher is the C 200 series having dimensions 1600 mm × 2000 mm driven by 400 kW motors. Table 4.1.
Cone Crusher an overview ScienceDirect Topics
Cone crushers have gained such wide acceptance that they may be regarded as standard in the intermediate-range size-reducing machines. A schematic diagram of a cone crusher is shown in Fig. 4.6 A.The drive is similar to that of a gyratory crusher. The inner cone or ‘crushing head’ is supported by the tapered concentric spindle, which is rotated by the
Breakage process of mineral processing comminution
202091 However, in mineral processing, it is not common to reach this low level of rate. For instance, Evertsson introduced cone crushers as a compressing crusher in which the rock is broken by squeezing between two surfaces [33]. He calculated the working velocity in a specific type of cone crusher at choke-level from 0.5 to 1 m/s.
