HP series cone crushers Wear parts application guide

• Closed circuit crushing (where the crusher product goes to a screen and the oversize material returns to the crusher) is needed when producing high quality products. 2. Check the feed size and gradation: • Oversize feed material decreases capacity and can cause abnormal wear of the liners • Too small a feed size for the cavity increases

Advanced comminution modelling: Part 1 – Crushers ...

 · As shown in Fig. 2a, a large jaw crusher was used to reduce ore from the mine to an 80% passing size (P80) of 100–150 mm. A cone crusher was then used in closed circuit with a screen producing a 20–30 mm product which could then be fed with some added water into a tumbling mill filled with heavy steel rods (called a rod mill).
