A new generation of high-efficiency coarse and medium-fine crushers: CI5X series impact crushers
·crusher consists of a heavy cast iron or steel shell/frame which includes in its lower part an actuating mechanism eccentric and driving gears and in its upper part a cone shaped crushing chamber lined with wear resisting plates concaves Construction detail and working of the crusher is as under
·The crushing chamber of a cone crusher is composed of the mantle and concave The particles in the crushing chamber are crushed by the squeezing of the mantle and concave
·The crushing work ratio of raw coal and tectonic coal is between and J/m 2 and J/m 2 respectively It can be inferred from this that tectonic coal is more easily broken when given the same energy In this paper aiming at the effect of the impact crushing characteristics of gas bearing coal the crushing
·It is against this background that the proposed research work has been formulated in order to study the crushing characteristics of various stones and to subsequently come up with an optimum dynamical ad structural design of a
Abstract In order to study the crushing characteristics of the ore particle group of a certain type of cone crusher combined with the working principle of the cone crusher the Tavares model is used to establish the ore particle group crushing model and the crushing characteristics of the ore particle group crushing simulation of the cone crusher are analyzed
·The reader is referred to Svensson and Steer 1990 for a discussion about the physics involved in rock crushing inside a cone crusher; Bearman and Briggs 1998 Lindqvist and Evertsson 2006 for comprehensive insights into the effect of liner wear and feed properties on the operational characteristics of cone crushers; and Wills and Finch
