Research And Application Of The New 3000t/h Coal And Gangue Screening Crusher

This article focuses on the current situation of the domestic and foreign coal crusher technology and the cases of the industrial site applying crusher technology, aiming at the present low efficiency and high energy consumption of the breaker with the teeth roll crusher as the researching object, focusing on the relationship between the teeth roll crusher layouts and the energy consumption. It finds out the causes of crushing roller teeth damage and puts forward some effective measures for improvement through the analysis on the situation of the double teeth roll crusher operation. It formulates roller teeth layouts scheme according to the roller gear layout principle, providing theory basis for the crusher roll teeth design.Besides, this article discusses the broken theory and summarizes personal scene practice work experience, researching of the crushing mechanism of coal and fragmented way and illustrating the new screening crusher crushing mechanism and broken theory through extent analysis on test theory. It puts forward the new type mineral sized installed power calculation formula and processing capacity calculation formula, which is tested and verified through practice. It draws the design data of tooth shape and structure through analyzing the key parts crusher broken teeth, tooth structure, broken teeth, broken after the space layout and the relationship between particle sizes. This article also introduces new double teeth roll grading crusher structure and design principles, which provides a new way for solving the shattering of coal and fracture process.
