خبير الاتصال2015年4月1日 These are all real effects and these are correctly observed in the crusher models shown here. The reason that these effects are captured is the preservation of the elastic energy at contacts when breakage occurs – which is a very positive attribute of this type of replacement breakage model in DEM. 10. Conclusions
خبير الاتصال2014年9月1日 The feasibility of the discrete element method to model the performance of a cone crusher comminution machine has been explored using the particle replacement method (PRM) to represent the size reduction of rocks experienced within a crusher chamber. In the application of PRM, the achievement of a critical octahedral shear stress

خبير الاتصال2021年11月12日 From a practical perspective, the cone crusher model proposed by Whiten [6] provides a reasonable compromise between representability and simplicity [16]. More complex mod-els may require information about the crusher geometry, and the subsequent calculation is time consuming [17]. Research on advanced control
خبير الاتصال2019年1月1日 Abstract. This work presents an extension and validation for a control oriented model of cone crushers. Compared to earlier work, the aspect of energy consumption was added to the model. Validation was carried out using measurement data from two different crusher models and was based both on laboratory data and field
خبير الاتصال1999年12月1日 The flow model is important since it describes how the rock material moves through the crusher chamber. Thereby the flow model provides input to the size reduction model. In turn, the size reduction model predicts the size distribution after compressing the rock material. Previously presented flow models have only in a simplified way described ...
خبير الاتصال2019年8月1日 In the piston and die test, the breakage energy is measured and the data is then used for calibrating the energy model. This paper aims to show how the particle size distribution and the energy model is modelled for a Sandvik Hydrocone crusher using the work by Evertsson, 2000, Lindqvist, 2005, see Fig. 1.
خبير الاتصال2002年10月1日 Abstract. In this paper we develop a performance model for impact crushers. The product size distribution is obtained as a function of the crusher’s rotor radius and angular velocity, the feed rate and the feed size distribution. The model is based on the standard matrix formulation that includes classification and breakage matrices.
خبير الاتصال2016年1月1日 Analytical models for estimating cone crusher performance have been developed by Evertsson (2000) and Eloranta (1995). Others have contributed to the modelling and understanding of wear (Lindqvist, 2005), product quality (Bengtsson, 2009) and process optimisation (Hulthén, 2010). These mechanistic or semi-mechanistic
