Effect of the roll stud diameter on the capacity of a high-pressure
Three types of roll having studs of different diameters were then modeled for numerical analysis. Using these simulation models, the effect of stud diameter in the laboratory-scale HPGR was evaluated. Grinding experiments on the laboratory-scale HPGR were conducted to verify the effect of stud diameter obtained from simulation.Accompanying to the tests, traces of wear on the roll surface are examined with a scanning electron microscope (SEM). The tests add up to an increase in wear rate, i.e., volume loss per 1000 revs, as a result of increasing grinding pressure, an increase of the maximum feedstock grain size and an increase of feedstock moisture.A new laboratory test for the estimation of wear in high

Ball-Mill Grinding Kinetics of Cement Clinker Comminuted in the
Integral grinding systems include a roller mill or a high pressure grinding roll circuit. These systems require only 45 to 60% of the specific power consumption of a ball mill circuit.The throughput capability of a high pressure grinding roll (HPGR), a critical process parameter, has been found to heavily depend on the sample type being processed. Existing HPGR test methods require the use of pilot machines and large sample quantities to assess the throughput characteristics of a certain ore type. Addressing the need for a laboratory Development of a laboratory scale procedure for predicting throughput
