The Bond's standard ball mill is used to determine the work index value of differ ent samples. The Bond work index is defined as the kilowatt-hours per short ton required to break from infinite size to a product size of 80% passing 100 µm. If the breakage characteristics of a material remain constant over all size ranges, the calcul ated work index would be expected to remain constant since ...

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

The test determines the Bond Ball Mill Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements*. Various correction factors may have to be applied. W = Wi (10/√P – 10/√F) Where W = Net power consumption in kWh/t Wi = Bond work index (either Imperial or Metric units) P = The 80% passing size of the ground product in µm F = The 80% passing ...

Ball mill - Wikipedia. A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
