Jan 04, 2018 The mill is powered by two 5500 hp D.C. motors. Nominal mill speed is 10.7 r.p.m. (78% critical) with a top speed of 11.3 r.p.m. The mill discharges through a grate with 3″ pebble ports onto a 14′ dia. x 13′ trommel screen with ¾” openings. On January 19, 1991 the mill was brought on line as a fully autogenous mill without pebble crushing.

Quantifying Grinding Efficiency Grinding

EF1 Dry grinding for the same range of work as wet grinding, dry grinding requires 1.3 times as much power as wet grinding. EF2 Open Circuit Grinding when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced.

Gyratory Crusher an overview ScienceDirect Topics

The gyratory crusher can, just like a jaw crusher, accept boulder sizes close to 1.5 m (for the largest equipment).. This crusher can handle products with a Mohs hardness that is not necessarily less than 5. As is the case for jaw crushers, there is not any mutual sliding on grinding surfaces, but simply rolling of the nut on concaves.
