Granite is a kind of igneous rock that formed by magma below the surface condensation; the main ingredient of it is feldspar and quartz. Granite is not easily weathered and has beautifulcolor, which can keep more than one hundred years. So does the luster appearance of it. Because of its high hardness and wear resistance, in addition to use as advanced architectural decoration engineering and the hall ground, it is still the first choice for outdoor sculpture.
It has widely applications in many fields, so the granite processing plants are many.In some areas that have abundant granite resources, granite processing is popular. And it accelerates the development of mining machines, such as stone cone crusher machines, jaw crusher machines, impact crusher machines and so on.
Cone crusher is suitable for the crushing of raw material in the metallurgy, construction, road construction, chemical and silicate industry. It can crushall kinds of ores and rocks with medium and abovemedium hardness. Cone crusher has largebroken, high efficiency, low energy consumption, product granularity, which is suitable for the medium and finely broken of various kinds of ores and rocks.
In the process of cone crusher work, motor through the driving device drives the eccentric set for rotating and moving cone under the forced motion of eccentric shaft sleeve do rotary oscillation.Section that dynamic cone near static cone becomes a crushing cavity.The material are impacted and broken for many timesunder dynamic and static cone moving. When dynamic cone leaves that section, the materials in that section have been broken to the required size. And thematerials fall under their gravity, from the bottom of the cone. To be broken material is sent into the cone crusherfrom the inlet.
In the granite processing plant, stone cone crusher machines are one of the main crushing machines. In addition to the stone cone crusher, there is jaw crusher for the first stage crushing. Stone cone crusher is used for the second stage crushing usually.
Cone crusher is a kind of advanced power, high crushing ratio, and high productivity of hydraulic crusher. Itis obviously different with the traditional cone crusherin the design of structure, and it focuses on the main benefits of each type of cone crusher that have been known so far. It is suitable for fine crushing and super fine crushing hard rock, ore, slag, refractory materials, etc. In the granite processing plant, it has performed very well.
Cone crusher cavity oscillating road has important influence on the performance of crusher work, when increasing swing stroke, various broken layers in the crushing cavity, the actual feed compression ratio increases, broken product quality improvement, calibration discharging granularity. When reducing swing stroke, crushing cavity actual feed compression ratio decreases, and broken product quality of the broken layer is deteriorated, calibration discharging particle size decreases. Taking raising the broken product quality into consideration, various broken layers in the crushing cavity and swing stroke need to be in the great value, but it cannot be over crushed and compacted.
Replacing broken wall in previous crushing machines is very slow, but replacing the broken wall ofcone crusher with new structure is very fast. The broken wall is fixed with hydraulic nut fastening. Upper and lower don't need to add any filler material on the back of the broken wall, changing work is so quickly, which reduces the labor intensity of workers.
