19 行· (b) In the column for a 2 in. setting, it is found that 20% of the output is between 1½ in. and 1 in. size (i.e., -1½ +1 in.) and 13% is between 1 in. and ¾ in. ( 1 +¾). Therefore, the quantity of output passing the 1½ in. screen and retained on the ¾ in.
16/04/2021· Tertiary cone crusher configurations typically work with a reduction ratio of 2.5:1 to 4:1. The reduction ratio is defined as the ratio of the feed size for which 80 per cent will pass (F80), divided by the product size for which 80 per cent will pass (P80).
passing percentage of cone crushers. passing percentage of cone crushers Feb11,2020"Fines in the crusher feed" is defined as material entering the top of the crusher which is already equal to or smaller than the crusher's closed-side discharge setting As a rule of thumb, the maximum number of fines in the crusher feed should not exceed25 .
processing group, has installed over 10 000 jaw crushers since the 1920s. . entage passing.,w eight % .. tured sand, and from small portable plants, HP cone crushers produce fewer fines and a higher percentage of on-spec product.
passing percentage of cone crushers. HP800 Cone Crusher. Stationary : One HP500, one HP300, two HP200 crushing "Amphibolite". Higher yield By operating the HP cone crusher on the lower end of its speed range, the product gradation can be shifted to produce fewer fines and a higher percentage of on-spec product.
19/07/2017· Cone Crusher Motor Sizing. Hard limestone, having an impact strength of 15, is fed from a secondary crusher set at 3¼-in. open side setting, producing stone having 80 percent minus 3¼-in. The product of the secondary crusher is screened at 5/8-in. The screening results in 5 percent minus 5/8-in. material in the tertiary crusher feed. Eighty tons per hour of this limestone is to be crushed to 100 percent
Cone crushers Cone crushers are a type of compression crusher suitable for crushing hard, abrasive materials. They represent a high initial investment but are low maintenance. Reduction ratios are typically up to 6:1. It is worth noting, however, that the cone crusher is limited to a certain top size of material feed. Cone crushers use approximately one horsepower per ton per hour making a
The curves, one for each closed side setting, will give an estimate of the cumulative percentage of material passing a given screen size on the horizontal scale with the screen opening in inches on the vertical scale.

16/04/2021· Successful application of a cone crusher within a crushing circuit is measured by the amount of material passing through the cone, the power draw of the machine, the size distribution of the products coming out of the circuit and the shape of the product. The goal is to efficiently and economically produce the target products, conforming with the required specifications.
01/01/1991· Power consumption and eighty percent passing size of product can be predicted for laboratory scale cone crushers based on rock mechanics tests and closed side settings. . In laboratory scale cone crushing the feed size does not affect the power consumption or product size over the normal operating range. . Power consumption and product size equations produced using a laboratory scale cone
19/07/2017· This factor is 80 minus the percent passing the product size in the feed, all divided by 80. The total and corrected horsepower hours required per short ton is the product of hp-hr per ton from step (5) and the correction factors, or the product of steps (5), (6), (7) and (8). Multiply the product from step (9) by the tons per hour to obtain the gross hp required. Cone Crusher Motor Sizing
Cedarapids Cone Crusher Primer Successful Cone Crusher Applications Successful application of a cone crusher to a crushing circuit is measured by the amount of material passing through the cone, the power draw of the machine, the size of the material coming out of the circuit, and the shape of the material coming out of the circuit. The goal is
Calculate the dry or wet aggregate crushing value to the nearest 0,1 % as follows and report it to the nearest 0,1% on form B4/3 or a similar form. Aggregate crushing value (wet or dry) percentage (m/m) = ACV B A = x 100 where : A = mass of test sample before test. B = mass of fraction passing the 2,36 mm sieve. 5 NOTES 5.1 .

The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the machine are
