Tips for maintaining efficiency in crushing circuits

Crusher setting: Efficiency. Size reduction and, ultimately, the crusher setting are directly proportional to the rotor speed; it largely dictates how many fines are produced. Slower rotor speeds can be used as a means of reducing fines, but may result in a product with more oversize or return than is wanted.
