This research involves the optimization of aggregate production using the Taguchi approach to maximize the production rate of Gneiss stone. The L18 orthogonal array has been used to investigate how the CSS, throw, eccentric speed, and particle size affect the products of the cone of the crusher (its cumulative weight fraction). The CSS, …
The strength is found irrespective to color. Amongst the aggregates of the three projects, quality of aggregate is the best in BBDMP as it has cone crusher & impact crusher. Thus the average strength of concrete achieved is 67.81 MPa in BBDMP where 50 MPa was the target. Download Free PDF. View PDF.

About Crushers. Crushers break down large rocks into smaller pieces to such as sand, gravel, or slag to be used in aggregate via pressure or striking. Typically, rocks will go through multiple rounds of crushing to reach the desired size. Crushers are also used in construction material recycling and mining operations.

with a unique rock-on-rock crushing principle, which significantly reduces the wear costs while offering superior cubical shape for the best quality fine aggregate produc-tion. VSI crushers are usually used in the final stages of the crushing process to shape flat material in quarries and to prepare materials for grinding in the mining industry. In
The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.
