Crusher Reduction Ratio - Mineral Processing Metallurgy

2016-1-12  Crusher Reduction Ratio I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.

Impact Crushing Impact Crushing Mobile Crushing

Impact Crushing was used extensively after WWII in Germany, to crush the concrete that was in abundance from bombed buildings. The product was then used again as an aggregate to rebuild cities, houses and roads. This concept was then adapted and improved over many years and is used successfully in the Mining and Aggregate industries throughout the world as well as in South Africa.
