·The breakage was predicted based on an empirical relationship between particle properties and breakage parameters [29] After that a combined breakage agglomeration model was proposed to represent the particle behaviour and to predict the product size distribution of a double roll coal crusher
·The two rolls 6 7 are both configured as solidly mounted rolls There is no floating roll Fig 7 as it is in a common DRC The gap between the rolls can be adjusted by two worm gears 9 A scraper 10 at each roll removes material if it sticks on the rolls The basic technical parameters of the machine are presented in Table 1
·An empirical relationship of Hardgrove Grindability Index HGI was established in terms of breakage parameters In order to model particle breakage behavior in a crusher breakage parameters and

·After that a combined breakage agglomeration model was proposed to represent the particle behaviour and to predict the product size distribution of a double roll coal crusher The model parameters were estimated from experimental data of single size crushing tests [30] Similarly a mathematical model of an industrial double roll crusher was
·Typically a double roll crusher is the suitable size reduction unit in the crushing process of coal gangue It was found to be the most vulnerable part in the whole crushing system Theoretically the Whiten model was initially used and further modified to predict the PSD of coal gangue in a double roller crusher [17 18]; additionally a
Double teeth roll crusher is mainly used in mining metallurgy chemical industry coal mine to crush coarse medium size fragile material Its feeding size is big discharging size is adjustable it can crush material of compressive strength below 160Mpa Especially in coal industry double teeth roll crusher can crush raw coal and coke directly after removing iron and impurity no
·Since for granulation processes the crusher operation has a decisive influence on the system stability a reliable mathematical model to represent an industrial double roll crusher of a urea granulation circuit is provided in this work The crusher was described by the model given by Austin et al [Austin Van Orden Perez A Preliminary Analysis of Smooth
