16.06.2015· The test determines the Bond Impact Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing crushers*. It is also used to determine the required openside settings ( jaw crushersBond Crushing Work Index Mobile Crushers All Mobile,,Bond Crushing Work Index Mobile Crushers All List Info What Is Bond S Law Of Crushing Mc World. In the 50s Bond came up with an empirical relation covering the range between Rit tinger and Kick's law, correlating the mass specific comminution work WM,K. Work Index  Metcom Expertise. It is a standard measure that brings all size reduction circuits onto a common basis for comparison. ItBond Impact Crushing Work Index Testing Machine,The Bond Crushing Work Index (CWI) describes the competency of the ore at larger particle sizes. It is used for the calculation of the actual crusher power requirements. Pendulum mounted hammers with scale.Test: At least 10 specimens preferably 20 specimens to be tested. Each broken stone has to pass a 3inch square mesh and be retained on a 2inch square mesh; Two hand safety release for the impact hammers
Read MoreDear all, while researching about the bond crushing work index (Wic), I realised, that the procedure of the test is described differently in different sources. The same seems to be true for sampling. Two examples: Bergstrom 1985 _ Crushability and Grindability: The hights of the hammers start forCrushing work index Calculation  Crushing, Screening,,The Bond crushing work index test (sometimes called the "impact work index" test) is noisy, and the difference you observed is perfectly reasonable. The paper by Angove & Dunne (1997) reports a standard deviation in crushing work index tests across laboratories as 4.5. The laboratory CWi value of 27.4 (metric) is almost within 4.5 units of the 22.4 value I calculated, so what you are observing is probably the natural variation in the crushingTestwork: Bond crushing work index  SAGMILLING.COM,The Bond lowenergy impact crushing work index (more informally, the Bond crushing work index) is not as common as the Bond ball mill work index, and it is a notoriously noisy test. The test is a 'perspecimen' test where individual specimens of prepared rock are handpicked by the test operator and placed into the apparatus. Typically twenty specimens are chosen to represent a sample and the,
