Bond Index Of Grinding Ball Mill. The standard bond rod mill work index test procedure is firstly to stage crush the feed to pass 12.7 mm, and size a representative sample.The test then involves a series of batch grinds in a standard bond rod mill.A bond rod mill is 0.305m by 0.610m, with wave liners (of a form described by bond), which runs at 40rpm and tilts as described below.
The slag after grinding reaches the following quality index: specific surface area is 500±50m2/kg; activity index: 7 days activity index is greater than 75%, 28 days activity index is greater than 80%; density is 3150±150kg/m3; free CaO content ≤ 5.0%; metal iron content ≤1.0%; MgO content is 13%; water content ≤2.0%; alkalinity coefficient ≥2.0; fluidity ratio ≥98%.
