Sizing a crusher can be done reliably calculated thanks to the ImpactCrushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper According to Bond’s Third Theory of Comminution the workenergy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product – the feed A crude test ...As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
