Bond Rod Mill Index

The standard Bond Rod Mill Work Index test procedure is firstly to stage crush the feed to pass 127 mm and sie a representative sample The test then involves a series of batch grinds in a standard Bond rod mill A Bond rod mill is 0305m by 0610m with wave liners of a form described by Bond which runs at 40rpm and tilts as described below

We are committed to building crushing, industrial grinding, ore processing and green building materials, and provides intelligent solutions and mature supporting products.
