Get PriceA certain crusher accepts a feed of rock having a volume-surface mean diameter of 0.75 inch and discharges a product of volume-surface mean diameter of 0.20 inch. The power required to crush 12 tons/h is 9.3 hp. What should be the power consumption if the same capacity and the volume surface mean diameter is reduced to 0.15 inch?
Oct 25, 2015 Example A certain crusher accepts a feed of rock having a volume-surface mean diameter of 0.75in and discharges a product of volume-surface mean diameter of 0.20in. The power required to crush 12 tons/hr is 9.3hp. What should be the power consumption if the capacity is reduced to 10 tons/hr and the volume-surface mean diameter to 0.15in? The mechanical efficiency remains
Few problems • A certain crusher accepts a feed of rock having diameter of 0.75 in and discharge a product of diameter 0.2 in. the power required to crush 12 tons per hr is 9.3 hp.

In general, a rock crushing plant will have a primary crusher, primary screen, secondary crusher(s) and secondary screen(s), and associated conveyors and stockpiles. It may also involve portable generators powered by diesel engines. Emissions of each pollutant must be less than 100 TPY for the facility to be a
length of the cylinder is to be 1.25 times its diameter. The casting is a square plate, each side = 10 in and thickness = 0.75 in. If the metal is cast iron, and the mold constant = 16.0 min/in2 in Chvorinov's rule, determine the dimensions of the riser so that it will take 30% longer for the riser to solidify
Rock crushers have a wide range of suitable material to choose from, whether it’s soft or hard, or even very hard, rock crushers can reduce those large rocks into smaller rocks, gravel, or even rock dust. Here are some typical materials that break or compress by industry crushers, such as Granite, quartz stone, river pebble, limestone
The gyratory crusher can, just like a jaw crusher, accept boulder sizes close to 1.5 m (for the largest equipment).. This crusher can handle products with a Mohs hardness that is not necessarily less than 5. – As is the case for jaw crushers, there is not any mutual sliding on grinding surfaces, but simply rolling of the nut on concaves
Jul 26, 2015 Also the screen cloth will have 50% or more open area, 25% of total feed passing over the deck, 40% is half size, and screen efficiency is 90%. And all of those stipulations are for a one-deck unit with the deck at an 18 to 20 slope
Jan 01, 2016 The size of a jaw crusher is usually described by the gape and the width, expressed as gape width. The common crusher types, sizes and their performance are summarised in Table 4.1.Currently, the dimensions of the largest Blake-type jaw crusher in use are 1600 mm 2514 mm with motor ratings of 250–300 kW
Feb 17, 2016 The Reduction Ratio is the ratio of the largest feed size that a crusher will accept (called gape) and the largest product size it will discharge (called set). Among the factors that influence the reduction ratio are: the amount of rock in the crusher; the percentage of voids; the toughness of the rock; the angle of inclination of the crushing
Cone crushers have been used as primary, secondary and tertiary crushers for quite a long time. ... system can adapt the closed side settings in accordance with different feed conditions and keep the system in choke feed, creating more rock-on-rock crushing action and increasing profitability. ... 19 0.75: 25 1: 32 1.3: MCH 900 MCH 900: 90-110
2-3 The diameters of steel shafts produced by a certain manufacturing process should have a mean diameter of 0.255 inches. The diameter is known to have a standard deviation of V = 0.0001 inch. A random sample of 10 shafts has an average diameter of 0.2545 inches. (a) Set up the appropriate hypotheses on the mean P. H0: P = 0.255 H1: P z
Oct 24, 2021 Call it the 'cook book approach' with rules of thumb like 0.001 of clearance for each inch of diameter up to perhaps 6 diameter, then 0.0015-002 per inch of diameter. This sort of rule-of-thumb does not factor in things like load, surface speed of the journal, and assumes a mineral based oil about like an SAE 20 weight is used
