They are designed both to reduce the size of large coal lumps to less than 6–14 in (15–36 cm), and also to feed materials out of bins and onto conveyors or chutes Conventional singleroll crushers use a simpler toothedroll design, and are commonly used to reduce coal to approximately a 2–3in (5–8 cm) top size2019年1月1日· This effect is well illustrated by a series of experiments on the grinding of coal in a small mill, carried out by Heywood 1 The results are shown in Fig 51, in which the distribution of particle size in the product is shown as a function of the number of revolutions of the millThe initial size distribution shows a single mode corresponding to a relativelyParticle Size Reduction and Enlargement ScienceDirect
