The aim of this study was to develop a new method for assessing the bond work index in a ball mill (bbwi), which is based on a first order kinetics present in the bond ball mill for grinding mineral raw materials (austin et al., 1981; ahmadi and shahsavari, 2009). theoretical basis of quick.
The bond ball mill work index (bbwi) test is carried out in a standardised ball mill with a pre-defined media and ore charge. the work index calculated from the testing can be used in the design and analysis of ball mill circuits the test requires a minimum of 10kg of sample that has been stage-crushed to 100% passing size of 3.35.
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.
The bond’s ball-mill work index is a measure of the resistance of the material to grinding in a ball mill. this index is widely used in the industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding and for ball mill.
The goal of this work is to create an equation to adjust a bond ball mill work index from one p 80 basis to another. the proposed model consists of two components, the variable coefficient that is determined from a specific work index determination and a fixed exponent determined by a calibration.
