The origin and characteristics of the world's first cone crusher!

The patent of the first cone crusher in the world was published in 1878, and the product was not made until 1898. Cone crusher was used in the United States at the end of 19. The spring cone crusher was designed by Simmons Brothers Company in Milwaukee, USA, so it was named Simmons cone crusher. This machine has a history of about one hundred years. Although gradually improved, the structure is becoming more and more perfect, but its basic structure has not changed significantly. On the basis of 1954 imitating Soviet 2 100 and 1650 spring cone crusher, China designed and produced 1200 spring cone crusher by itself. 1958 designed and manufactured a large 2200 spring cone crusher. After years of repeated research and practice, the spring pressure of the old series is insufficient and the strength of the parts is low, which overcomes some structural shortcomings. At present, there are 14 cavities in five specifications: 600, 900, 1200, 1750 and 2200.

The machine adopts hydraulic system to adjust the size of the crusher's ore drawing day, and the hydraulic system can effectively ensure the safe operation of the equipment. When there is foreign matter in the crushing cavity, the hydraulic system can make the moving cone retreat automatically, and when the foreign matter is discharged, the system can make the retreating moving cone reset automatically. The crushing cavity type refers to the geometric space formed between the moving cone and the fixed cone. The shape of crushing cavity has great influence on the performance of the whole machine. Chamber crusher is the main technical index of crushing. The labyrinth seal device is used to replace the water seal used in the past, so that dust and impurities can not enter the human body, thus ensuring the cleanliness of lubricating oil, prolonging the service life of sliding bearings and thrust ball bearings, and making the machine run reliably. The new structure of cone crusher can quickly replace the wall breaker. This machine adopts high-pressure displacement sensor, and the position of ore outlet is adjusted in the operation room. As long as you press a button, it will be displayed on the operating table, and you can see the size of the ore outlet that needs to be adjusted, which is very convenient and accurate. The crusher is suitable for three-stage crushing or four-stage crushing in metal mine concentrator; Suitable for building materials or nonmetallic mines and civil engineering. Especially in areas where the supply of natural sand required by civil engineering is insufficient.
