Dec 26, 2015 Producing such a fine crush generally requires multiple crushing stations of up to 4 being but as a minimum of 2 being oversized. The gape determines the maximum size of material that can be accepted. Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape.

Oct 06, 2016 The total direct cost of crushing 2,000 tons in eight hours is generally about 3½d. per ton, while in a smaller plant of half the hourly capacity it amounts to about 4d. per ton. This saving of ½d. per ton is offset by the fact that the capital cost of the larger installation will be approximately 50% more than that of the smaller one.
