Get QuoteTestwork Bond Ball Mill Work Index. The Bond ball mill work index is one of the most commonly used grindability tests in mining, and is often referred to as the Bond work index . The test is a locked-cycle test where ground product is removed from test cycles and replaced by fresh feed. The test much achieve a steady-state before completion.
Get QuoteThis is because work index frequently changes as a function of the product size in comminution. If target grind size during a project is changed, or if the test is run at the wrong product size, then it is necessarily to provide a correction. The goal of this work is to create an equation to adjust a Bond ball mill work index from one P 80 basis
Get QuoteThe Bond Index conforming rod charge consists of 6 rods of 1.25 diameter and 21 length. 2 rods of 1.75 diameter and 21 length. The grinding jar for the Bond Index Rod Mill is 12 x 24 in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.
Get QuoteThe rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm 2 in. and produce a product in the size range of 3000 to 270 mm 4 to 35 mesh.
