Cone Crusher VS Jaw Crusher

The sparse decomposition of vibration signal is an important part of the fault diagnosis of Double Cavity impact crusher, But calculation of sparse decomposition is very large, and it is difficult to fulfill signal processing, After analysing characteristics of Double Cavity impact crusher, this paper proposes to apply the hybrid algorithm, DEPSO which mixes the advantages of particle swarm optimization (PSO) and difference evolution (DE) algorithm to extract signal feature of Double Cavity impact crusher and deal with the search of the best atoms during the signal decomposition,cone crusher
, With the combination of PSO and DE, this method avoids falling into the partial optimal solution, Besides, after the algorithm imports the chiasm and variation operations, its adaptability has made a great improvement,jaw crusher, The test result shows that applying DEPSO to extracting signal feature of Double Cavity impact crusher improves the search speed, the efficiency and accuracy of decomposition, and the calculation has also dropped down dramatically,
The physical and mechanical characteristics of intact rocks depend on the way of their formation, sustained deformations and the process of wearing a specific rock has been exposed to,stone crusher
, These characteristics have a rather high influence on the technological process of extraction and dressing of mineral raw materials, However, the mechanical characteristics of rocks due to use of explosives for their extraction in the open pit have a more significant impact, The rock blocks extracted by blasting which are larger than the opening of the primary crusher are usually fragmented by hydraulic hammer,The paper presents the results of the testing of impact of rock hardness on fragmentation of rocks by means of hydraulic hammer and during crushing in impact crusher, The testing was carried out on the rock samples from five quarries, According to the obtained results the hardness has a considerably larger impact on the fragmentation energy by hydraulic hammer than on the crushing energy in impact crusher,
