Different machines to meet all needs
these inefficient size separations is that most grinding circuits closed by hydrocyclones operate with high circulating loads that oscillate between 230 – 450%. (See figures 2, 3, 4 and 5 for circuit types) The grinding operation in a mineral processing facility typically consumes the majority of the energy used.
