moving surface of a crusher roll or jaw plate and the stationary plate surface at which point the material will be pinched. Angle varies with machine size and material lump size. Bond Work Index (BWI) — Kilowatt hour (kWh) per short ton required to reduce the material to 80% passing 100 microns. Breaker Block (Breaker Plate) — The steel anvil

crusher tools E.G. Jaw liners are subject to numerous pressure and impact stresses. Several other factors affect the wear lifetime of crusher wear parts as listed in below Diagram . Wear occurs in all crushers, however wear costs can be controlled by selecting the correct crusher type for the abrasive content of the material to be crushed.

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and ...

Jan 01, 2016· Primary crushers are solidly built to receive large lumps of rock directly from the mines and designed for large tonnage throughputs. Basically, gyratory crushers consist of a fixed solid conical shell or bowl (also called concaves) and a solid cone within the bowl called a breaking head (Figure 5.1).The breaking head is fixed to a central spindle, which is hydraulically suspended or ...

crusher were compared with those of the Bond crushing energies (estimated from the Bond crushability index) of the rocks. Also, the effect of the Bond crushability index on the estimated crushing energy of the rocks was studied. Materials and methods In this work, nine different rock specimens were obtained from some mines in Iran.

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 open-side settings (jaw crushers and gyratory crushers) or closed-side settings (cone crushers) for a given product size. P80 = 25400 x Oss x ...

Jun 16, 2015· Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond's Third Theory of Comminution, the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product – the feed.
