  • Effect of Feed Rock Size Distribution on Crusher Performance

    22.10.2015· Sized feed for reduction crushers is generally a screened feed which has definite maximum and minimum limits. The effect of the undersize in the feed upon the capacity of the crusher depends upon several factors. If the crusher is a primary breaker, and the discharge opening is large, undersize will usually sift readily through the voids between the large pieces of material, and

  • Crushing Products Size and Shape -What to Expect

    26.02.2016· Following the curve down to the 1.5″ line, we find that 43% of the primary crusher output may be expected to pass this screen opening; 57% will be retained, which means that we must provide secondary crushing capacity to take care of 57 tons for each 100 tons fed to the primary crusher.

    crusher setting affect size distribution. Figures 3.7, 3.8 and 3.9 show the relationships that were obtained for a laboratory crusher, for which the relevant parameters were determined to be: «. = 0.25, fi = 2.523 and £ =* 0.263. a. Important to note that, like the Apoll> model of a crusher, this model assumes the output gradi.ig to be independent of the feed size. Relative frequency of

    Maximum feed size. Reduction ratio must be limited to 3 (-4). Recommended max feed size is 50 mm. Correct feed distribution. Feed distribution should be non segregated and evenly distributed around crushing cavity. Setting closer to required product; Correct choke point. This means the right selection of cavities for feed in question. Crusher itself. New generation cones will produce considerably better shape than so called old generation. This is due to improved crusher

  • Cone crusher basics in 4 minutes — SRP

    It’s hard to overstate the importance of feed size in a cone crusher. It is vital that you know, as accurately as you can, the size distribution of the raw material. The Sandvik CH cone crusher can be calibrated to achieve specific results, maximize productivity and minimize wear, but any calculation will be undermined without a solid understanding of what is going in to the crusher

  • Impact Crusher Working Principle

    23.06.2015· At the time of taking a feed sample for laboratory testing in the pendulum device, relevant performance data such as power, feed rate and size distributions for feed and product were taken on the operating crusher. Several thousand rocks have been broken during tests with

  • Rock Crushing Rule of Thumb Mineral Processing &

    16.12.2015· The product of a jaw crusher will have a size distribution such that the -80% fraction size (d80) is slightly less than the open-side setting of the crusher. For example, if the open- side setting is 6 inches, the d80 product size will be 5¾ inches. Source: Unknown ; In a hard rock mine, the product from a jaw crusher will tend to be slabby, while the product from a gyratory crusher may tend

    A Fritsch jaw crusher with maximal feed size 95 Impact crushers provide better grain-size distribution of RA for road construction purposes, and they are less sensitive to material that cannot be crushed, such as steel reinforcement. Generally, jaw and impact crushers exhibit a large reduction factor, defined as the ratio of the particle size of the input to that of the output material. A

  • The influence of liner condition on cone crusher

    01.01.1990· The crusher manufacturers normally recommend a particular liner profile dependent on the expected feed size distribution. The classification parameters, K 1 and K2 (which are indicators of the smallest particle to pass through the crusher without breakage, and the size above which all particles are broken, respectively), would therefore be expected to be significantly affected by the liner

  • Primary Crusher an overview ScienceDirect Topics

    Primary coal crusher: Used for larger coal size. The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher. The primary crusher converts the feed size to one that is

  • Perfecting the Performance of Secondary Crushers E & MJ

    This then has an influence on the wear of the individual crushers and the particle size distribution in the final product.” For example, in a simple arrangement, if the primary crusher produces a high quantity of fines, then more material is screened out and less material is fed to the secondary crusher, thus reducing wear. Various factors can influence the process, for example, the feed

  • SAG Mill Grinding Circuit Design

    06.06.2016· Critical-sized particles are those where the product of the mill feed-size distribution and the mill breakage rates result in a buildup of a size range of material in the mill load, the accumulation of which limits the ability of the mill to accept new feed. While critical-size could be of any dimension, it is most typically synonymous with pebble-crusher feed, with a size range of 13—75 mm
