Crushing Products Size and Shape -What to Expect 911

The difference between the cumulative percentages at the 3.5″ and 1.5″ points on the curve gives us the amount, of such product to be expected from the output of the primary crusher This is 85 minus 43, or 42% of the primary crusher product. If our problem had covered a crushing condition calling for 80 instead of 85% passing the amount of CO2 uptake in one ton of recycled crusher-run stone to be approximately 11 kilograms. Finally, using this value, the life cycle of CO2 of concrete structures was calculated and shown to be approximately 5.5% less when the CO2 uptake is taken into account compared to when it is not taken into account. 1.

Crushers QueensMineDesignWiki

Crushers play an important role in the material handling process for underground mine operations. The main purpose of a crusher is the size reduction of the feed. This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller pieces.Crusher-Run Stone shall consist of sound, tough, durable broken stone. It shall be reasonably free from soft, thin, elongated, laminated, friable, micaceous or disintegrated pieces, mud, dirt or other deleterious material.
