manufacturing process of aggregate in construction

Jan 01, 2007· Aggregate manufacturing typically starts by blasting rock masses and is followed by a series of crushing stages. Comminution in typical hard rock quarries is sketched in Fig. 1.ASTM particle size distributions of select aggregate products are also shown in Fig. 1 ().Crushing operations can accommodate some adjustment to match the demand for each …

May 23, 2017· 1. High pivot point crushing action. This ensures the material is fragmented when it first contacts the mantle. The resulting fragments then progress to the next crushing cycle where they create an inter-particle rock-on-rock crushing action, which maximises the generation of cubical materials. 2. Large eccentric throw

Calculation of Aggregate Crushing Value. The ratio of weight of fines formed to the weight of total sample in each test shall be expressed as a percentage, the result being recorded to the first decimal place. Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve. W1-W =Weight of surface dry ...
