5.1.2 Impact crushers Breakage is achieved by impact using either hammer action on the individual particles or by sudden impact from a high velocity trajectory. High reduction ratios of between 20:1 and 40:1 can be achieved with hammer type impact crushers. Only low reduction ratios of about 2:1 can be achieved with kinetic energy type impact ...

Primary and Secondary Sizers feature a unique hydraulic product size adjustment, which allows producers versatility if the product size requirements change. This feature allows producers not only the option of maintaining original size specifications, but also gives them the ability to adjust to meet changes in product size requirements.

The term "secondary crushing" has become well established and familiar through long usage; it applies to the crushing stage, either single or multiple, which follows immediately after the primary crusher, taking all or a portion of the product of the primary crushing stage as its feed.The term should not be used, as it sometimes is, to designate …

Roll Crushers are compression-type machines, so output gradation is controlled mainly through the gap setting between the rolls. A wider setting results in a coarser product. A wider setting also provides greater throughput. Single Roll Crushers feature a low-speed crushing roll that crushes material against a curved crushing plate.

The various manufacturers make specialized crushers for various processes, such as re duction of long coils of metals into short lengths, re duction in size of run-of-mine coal …

secondary crushing (although impact crushers are sometimes used), which typically reduces material to about 2.5 to 10 centimeters (1 to 4 inches). The material (throughs) from the second level of the screen bypasses the secondary crusher because it is sufficiently small for the last crushing step. The output from the secondary crusher and the ...
