Study Of Improvement And Its Application Of Overweight Type PydΦ2200 Cone Crusher

Crushing of material is a necessary technical process for country economy of many departments. Many scholars on crushing studying are putting forward new process called "more crushing and few milling" or "crushing instead of milling", i.e., the granularity of crushing production is mainly made by crushing instead of milling to improve the ability and to save its milling energy of milling machine. Studying and developing high efficiency and energy saving crashing machine will satisfy the demand of "more crushing and few milling".Since 80's the project of crushing have been an independence subject which is necessity result of science and technology development. Crusher, as one of main crushing machine in crushing engineering, has been pain more and more attention by studying,designing department and using enterprises. Changing or improving still used crusher by adopting advanced design thought abroad and existing machining ability in the nation is also an important task, which can fast reduce the difference with advanced equipment abroad and is helpful to develop new crusher.Along with several decades, most of crushing enterprises are all taken much count of the cone crusher made in our country. But because of lacking larger machine tools it is more difficult to repair used crusher in crushing workshop. Furthermore, the equipment enterprises are still lacking more efficient sold service. Many problems on used crusher are still not been solved or improved.It analyses the structure of the conventional type cone crusher and the flaw exposing in the past production, then pointedly transforms the conventional typeΦ2200 cone crusher. Several technical improvements for a used cone crusher in our enterprise have been made, including optimization of most technical parameters, increasing the thick of frame, changing the link manner between the frame of bowl bearing and the frame of machine, changing the link manner of transmission shaft, etc. Through the transform of insurance and locking system, we can increase the crush power and the crush efficiency, eliminate the conventional type cone crusher's flaw of inefficiency resulting from inadequate of insurance and locking system's power and big vibration, much trouble and working capacity while running. Also some problems found in process have been completely solved. Crushing tests and machine running results show that the improved cone crusher can increase the reliability of equipment running, reduce the failure ratio and spare parts of the equipment, and increase the efficiency of crushing and its production ability. It satisfies the second period producing need of the Meishan Mining Company. It can accelerate development steadily and kilter realize aim of economy to the Meishan Mining Company. Success for improvement of overweight typeΦ2200 cone crusher, it can offer studying and improving experience for making company and using factory in our country, and making them cost few money and time。Because of the hardness and more difficult crushing of ore in the Meishan Mining Company, it can prove that overweight typeΦ2200 cone crusher has better adaptability and value of extending. at the same time, it can offer more practicality data for producing and studying heavy cone crusher in our country.
