WHAT IS A CRUSHING PROCESS? / CRUSHING. In order to make use of the rocks or ores obtained through quarrying/explosion in the Mining and Construction sectors, the materials need to be crushed to reduce them to a smaller size. We call this process SIZE REDUCTION or CRUSHING. The goals of the size reduction are as follows: 1.)

Manufactured sand (M-Sand) is artificial sand produced from crushing hard stones into small sand-sized angular shaped particles, washed and finely graded to be used as construction aggregate. It is an alternative to River Sand used for construction purposes. It is produced from hard granite stone by crushing.

3.Crushing: Crushing is the first mechanical stage in communation process for extraction and refining of ore. It is generally a dry operation and is usually performed in two or three stages.i.e primary,secondary and tertiary stage. In Primary crushing the feed size of ore can be as large as 1.5m and is reduced to 10-20cm in heavy duty machines.

b The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample that is crushed finer than a 2.36-mm sieve when a sample of aggregate passing the 13.2-mm and retained on the 9.50-mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN.

The aggregate crushing value formula is given below, Aggregate crushing value = (W3 / W) or W3 / (W2 – W1) W1 = Empty weight of cylindrical Measure. W2 = Weight of Aggregate with Cylindrical Measure. W = W2 –W1 = Weight of Aggregate Sample. W3 = Weight of crushed aggregate sample passed through 2.36 mm IS Sieve.
