Investigating the effects of feeding properties on rock
For this purpose, an 8 mm bar sieve was used (Fig. 2). The particles passing through the 8 mm bar sieve were removed from the feed, and the remaining were weighed based on the predefined feeding quantity (F1 – F3). The CSS of the crusher was set to 8 mm for the crushability tests.

SIEVE ANALYSIS OF FINE AND COARSE AGGREGATES
When the specification requires that the amount of material finer than 75 μm (No. 200) be determined, perform Step 3 through Step 9; otherwise, skip to Step 10. Nest a sieve, such as a 2.0 mm (No. 10), above the 75 μm (No. 200) sieve. Place the test sample in a container and add sufficient water to cover it.
