  Equivalent Circuit of Transformer Referred to Primary

  Nov 30 2020  Here R 1 X 1 and R 2 X 2 are the drops due to primary and secondary winding resistance and leakage reactance respectively. The current I 2 is the counter balance current I 2 of secondary on the primary. Now we can further simplify the equivalent circuit either by shifting the primary parameters to the secondary side or vice versa this reduces the complexity of

  Crusher

  The secondary crusher is mainly used to reclaim the primary crusher product. The crushed material which is around 15 cm in diameter obtained from the ore storage is disposed as the final crusher product. The size is usually between 0.5 and 2 cm in diameter so that it is suitable for grinding. Secondary crushers are comparatively lighter in weight and smaller in size.
