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 surface of a crusher against which material is crushed by impact or pressure. Bridging — Blocking of crusher opening by20150505 Bond Efficiency-GMG-ICE-v1-r04 Determining the,,Where, WioACTis the Actual Operating Bond Work Index (kWh/t), W is the specific energy input (kWh/t), P80 is the 80% passing size of product (µm), and F80 is the 80% passing size of circuit feed (µm). 2. Calculate the Standard Circuit Bond Work Index (WiSTD) for the material being processed (equationDesign, Fabrication and Testing of a Double Roll Crusher,include jaw crusher, gyratory crusher and roll crusher. A,The standard measure of energy demand is Bond work index. The work index, w i, represents the,Equation 2 indicates that to estimate the diameter of the feed , the nip angle is required.
