Effect of core diameter on the Bond impact crushing work index test The Bond low energy impact (crushing) work index test is specified to be performed on rock specimens between 50 mm and 75 mm in effective diameter.
Bond Work Index - an overview ScienceDirect Topics. The low energy crushing work index laboratory test is conducted on ore specimens larger than 50 mm, determining the crushing work index ... Berkowitz (1994 p.96) gives a generalized variation of the Hardgrove index with coal rank.
Jan 01, 2016 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. ... avoiding over crushing by using low energy impact or compression and by closing the circuit with a 3327 μm screen.

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 by large pieces of …
kept as low as practicable. ... It implies that the specific energy required to crush a material, for example from 10cm down to 5cm, is the same as the energy required to crush the same material from 5mm to 2.5 mm. Rittinger, on the other hand, assumed that the energy required for size reduction is directly ... and Bond calls this the Work Index.
