An HSI crusher is suitable for crushing soft to medium-hard materials, such as limestone, gypsum, lignite, coal, coke, weathered shakes, and phosphate. The horizontal shaft impactor is better suited for softer, less abrasive stone. VSI crushers can handle hard and abrasive rocks, such as granite, gravel, trap rock, and basalt.

The crushing action in the VSI Crusher is simulates the action of nature eroding the particle to cubical shape. For chemical Industry and Cement Industry. Our VSI can provide fine feed to grinding ball mill so smaller grinding mill can achieve the capacity required and increase mill liner life. Quality manufactured sand 0-5 mm and premium

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.

For REMco crushers, the reduction ratio is calculated as the relationship of the maximum feed size to the desired product size. For example, with a feed of -2" and a product requirement of -1/4", the reduction is 2.0 ÷ 0.250 = 8. Maximum recommended reduction ratios for REMco crushers are SandMax – 16:1and RockMax – 8:1.
