A small bin was modeled for the cone crusher chamber when the material accumulates and perfectmixed after the crusher. The product particle size distribution of the cone crusher is shown in Fig. eccentric speed settings in Fig. 2 are 280, 360 and 440 rpm. It can be seen from the plot that the CSS and eccentric speed of a cone crusher can affect the final PSD significantly.

The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the ...

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. The mill was difficult to operate in that it quickly overloaded and required extensive grind out periods.

How to Size a Crusher and Grinding Mill ... Pebble Mills. Where a finely divided product must not be adulterated by iron, the pebble mill is the logical choice. These mills are lined with a nonmetallic material such as porcelain or stone, and employ flint or stone grinding bodies. Thus, iron contamination caused by grinding is kept to a minimum.
