    The breakage equation is discretised to give a matrix form, from which it is demonstrated that during roller milling of wheat, particles break independently of one another. This is an important assumption of breakage equations for many comminution operations and experimental results are presented, which confirm its applicability to the roller milling of wheat grains.

    breakage function for roller milling could be deter-mined by milling narrow size fractions of wheat separated by thickness using slotted sieves. They found that under Sharp-to-Sharp milling the break-age function could be described adequately by a linear function in x over a range of output particle sizes from 250–2000mm, and a quadratic function

    This is possible because particles break independently during roller milling. The pattern of breakage for individual particles is called the breakage function. This paper considers the form of the breakage function and determines it experimentally for roller milling of wheat.The breakage function is shown to depend critically on the ratio of roll gap to input particle size (the milling ratio).

    Wheat flour milling involves repeated breakage (by roller milling) and separation (by sifting) of flour particles to give efficient recovery of fine flour relatively free from bran contamination. A starting point for modelling the behaviour of mixtures of wheat kernels is to be able to measure the variation in kernel properties within the mixture.
