Abstract
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 consumption at the crushing stage by a jaw crusher; which is the most widely used type of crusher. The existence of accurate power prediction as well as optimizing the steps for primary crushing will offer vital tools in selecting a suitable crusher for a specific application. In this work, the specific power consumption of a jaw crusher is predicted with the help of the adaptive neuro-fuzzy interference system (ANFIS). The investigation included, aside from the power required for rock comminution, an optimization of the crushing process to reduce this estimated power. Results revealed the success of the model to accurately predict comminution power with an accuracy of more than 96% in comparison with the corresponding real data. The obtained results introduce good knowledge that may be used in future academic and industrial research.
Highlights
During the processing of raw materials in different industries such as the mining and cement sectors, the size reduction of fed rocks is primarily a mechanical process [1]
This study presents a jaw crusher, which is a key tool in the dry process of making a cement plant
A set of 32 specific energy consumption values were measured at various crushing conditions to generate the corresponding adaptive neuro-fuzzy interference system (ANFIS) model. Another set of eight measured data were used to evaluate the accuracy of the generated model to provide the specific energy consumption
Summary
During the processing of raw materials in different industries such as the mining and cement sectors, the size reduction of fed rocks is primarily a mechanical process [1]. The rock blasting process is the most primary, and the first significant stage in these industrial sectors through which massive rocks are broken and fragmented into suitable smaller sizes before feeding to the processing plant. This process can be realized in mechanical systems commonly known as crushers. Rocks meet crushing or compressive failure, where rocks of two distinct size ranges are obtained In this mode, the coarse rocks are produced due to tensile failure, while the small size rocks result from compressive failure occurring at loading points or due to shear stress between projected rocks [3]. The later mode can occur when too fast feeding of a crusher is applied, which is usually
