Computer simulation of the Bond Grindability test

A new Bond grind ability test method was developed which not only significantly reduces the experimental testwork involved by the traditional technique but also implicitly provides the necessary data for as many product sizes that are required. The new method is based on a computer simulation which closely parallels the traditional method. A population balance model of size reduction forms the kernel of the simulator. This model is based on a well-known mathematical representation of the comminution process which has been adapted specifically for the traditional Bond mill. The development of the model is discussed in detail and the simulation methodology outlined. The simulation results. are presented and compared with results obtained using the traditional method.
