Cone crusher is one of the most commonly used crushing equipments in mining equipment, and it is also the most commonly used crushing equipments in various production lines. The knowledge about cone crusher has been told a lot before, today we will talk about how the world's first cone crusher was born?
The patent for the world's first cone crusher was published in 1878, and the product was not made until 1898. The United States in the late 19th century began to apply the cone crusher. The spring cone crusher was designed by the two Simmons brothers in Milwaukee, U.S.A., so it was named Simmons Cone Crusher.
The machine so far about a hundred years of history, although the gradual improvement, the structure is becoming more and more perfect, but the basic structure has not changed significantly. In 1954, our country designed and produced 1200 spring cone crusher on the basis of 2100 and 1650 spring cone crusher of USSR.
In 1958, the company designed and manufactured a large-scale 2200 spring-type cone crusher. After years of repeated research and practice, successively overcome the old series of insufficient spring pressure, low strength of the parts and some shortcomings in structure, now the mass production of spring cone crusher 600, 900, 1200, 1750, 2200 five specifications and 14 kinds of cavity.
The machine has a hydraulic system to adjust the size of the crusher discharge day, 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 automatically retreat, and when the foreign matter is discharged, the system makes the retreating moving cone automatically reset The crushing cavity type refers to the geometric space formed between the moving cone and the fixed cone.
The shape of the crushing cavity has a great influence on the performance of the whole machine. The crusher cavity shape is the main technical index of crushing. The labyrinth sealing device is adopted to replace the water sealing used in the past, so that the dust and impurities can't enter into the machine body, which ensures the cleanliness of the lubricating oil, prolongs the service life of the sliding bearing and thrust ball bearing, and makes the machine run reliably.
The new structure of the cone crusher replaces the crushing wall very quickly, the machine has chosen a displacement sensor that is resistant to high pressure, and the adjustment of the position of the discharge opening is carried out in the operation room. As long as a key is pressed, there is a display on the operating table, and you can see the size of the discharge opening that needs to be adjusted, which is very convenient and accurate.
The crusher is suitable for the third stage crushing, or the fourth stage crushing in metal mine beneficiation plant; it is suitable for building materials or non-metallic mines and civil engineering, especially in the area where the supply of natural sand needed for civil engineering is insufficient.
The development of industry is strongly advancing the progress of society, and the cone crusher and other equipment of Red Star Machinery have also been helping the society to move forward.
