Aggregate quality is measured in terms of product gradation, particle shape and mechanical properties. Feed gradation, crusher setting and crusher speed affects the specific energy The main objective of this study was to determine a meaningful relationship between the particle size distribution characteristics of the blasted rock (P 20, P 50, P 80, or Top-size) and crusher throughput which is one of the main productivity indicators (time and energy consumption) of the jaw crusher and to discuss the Evaluation of blast fragmentation effects on jaw crusher

Evaluation of size reduction process for rock aggregates in cone crusher

The crushability, grindability, and cutability of rocks are associated with many factors. During the size reduction processes in a jaw crusher and rod mill, crushing and grinding energy consumption increase when finer size fractions of the product are desired (Zeng and Forssberg 1992).Heikkilä (Heikkila 1991) reported that the lithological The simulation results show that due to the high no-load power consumption of the jaw crusher, the optimal switching control of the jaw crushing process can achieve considerable energy saving and cost saving as compared to the variable load-based optimal control. However, switching the jaw crusher will result in severe impact in Optimal energy management for a jaw crushing process in

Applied Sciences Free Full-Text A Comparative Study of

Crushing is a vital process for different industrial applications where a significant portion of power is consumed to properly blast rocks into a predefined size of fragmented rock. An accurate prediction of the energy needed to control this process rarely exists in the literature, hence there have been limited efforts to optimize the power energy to blast materials into certain sizes of shattered boulders. Because accurate predictions of the energy required to manage this process are rare in the literature, there have been few efforts to reduce power consumption at the crushing stage by using a jaw crusher, which is the most common type of crusher. TheSimulation of Energy Consumption in Jaw Crusher Using

It appears that DEM is a suitable method for predicting the crushing energy of the spherical rocks in the jaw crusher. The fracture behavior of the crushed rocks was examined and compared by theAbstract. In this study, an analytical perspective is used to develop a fundamental model of a jaw crusher. Previously, jaw crushers were modelled in regard to certain aspects, for example, energy consumption (Legendre and Zevenhoven, 2014) or kinematics (Oduori et al., 2015). Approaches to date have been mainly property specific.A fundamental model of an industrial-scale jaw crusher

DETERMINATION OF THE INFLUENCE OF JAW

Abstract: In the paper, in accordance to the theory, it is shown that the relative energy consumption of a jaw crusher depends on the average diameter of the material entering the crusher and the width of the discharge port. An experimental study has shown that the energy consumption depends also on the frequency of the jaw swing. In By using the data of E.A. Hersam and F.C. Bond’s equation for energy consumption in comminution, a method was developed to analyze the performance of industrial jaw crushers. The study showed that industrial jaw crushers are generally operated below capacity. The study also showed that industrial jaw crushers generally have Capacities and performance characteristics of jaw crushers
