Crusher - an overview | ScienceDirect Topics

Depending on circuit configuration, large single-line secondary/tertiary crushing lines have a nominal installed power of 3 MW, and the capacity to crush 25 to 40 ktpd per line. A typical large cone crusher (with applications in crushing circuits, pebble-crushing circuits, and secondary crushing for feed to HPGRs) is depicted in Figure 17.7.

Current Transformer Basics and the Current Transformer

A current transformer of say 500/5, will produce 5 amps in the secondary for 500 amps in the primary conductor, 100 times greater. By increasing the number of secondary windings, Ns, the secondary current can be made much smaller than the current in the primary circuit being measured because as Ns increases, Is goes down by a proportional amount.

Transformer Formula

Answer: As we want to determine the output current in the secondary coil, we use the first equation, →, = 2.4 * 10 A = 24 A. I s = 24 A. 2) We have a transformer with an output current on the secondary coil of 30 A and an input current on the primary coil of 2000 turns of 6 A, determine the number of turns on the secondary coil.

Secondary Crushing Equipment

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.
