What are the types of crusher production lines
The representative product of the vertical crusher, the vertical shaft impact fine crusher, is widely used in the fine crushing of materials in the iron ore, gold mine, cement, glass, ceramic, electric power, and steel industries. First talk about the vertical crusher (that is, the main shaft is vertical). The machine has become a hot-selling product by breaking and replacing mill since its introduction in the 1980s. As a fine crusher, the average output particle size is ≤3～4mm, and 90% is fine powder, which reduces the feed size of the ball mill and reduces Increased by 20% to 30%.
After more than 20 years of development and evolution, the vertical shaft crusher has evolved from single-strike crushing to impact counter-strike crushing from the first to fifth generations. The service life of the one-to-one hammer is more than 4 times longer than that of the old model. However, if you choose a vertical crusher for the crushing of road construction materials, it is a wrong selection, which requires the horizontal crusher we will talk about below.
Horizontal crusher (that is, the main shaft is used horizontally). Its types are: horizontal shaft impact crusher, horizontal shaft hammer crusher, ring hammer crusher, etc. The gap and geometric angle of the jaw crusher can produce all kinds of materials required, and the material Good shape (six prism) and high compressive strength. The structural characteristics of the horizontal crusher are: high production capacity, low energy consumption per unit product, large crushing ratio, replacement of multi-stage crushing, that is, when the process conditions are limited, this model can complete product production from coarse to fine crushing. The whole process.
Roller crusher (crushing by the squeezing and shearing force of the rollers). The main advantages are: simple structure, compactness, light weight, reliable work, convenient adjustment and crushing, and the dryer manufacturer (ie, toothed roller crusher) can be used without foundation to apply it to large pieces of material to small pieces of material (Contains a certain amount of moisture) occasions are beyond the reach of other crushers. The disadvantages are: low production capacity, continuous and uniform feeding is required, uneven abrasion on the roller surface, product particle size is not easy to be uniform, and frequent repairs are required. Generally, the roller surface of roller crusher has two kinds of fixed and replaceable, and there is also a roller surface with teeth.
Jaw crusher is often used as a rough crusher, low cost, large output, solid structure, simple structure, reliable work, large size range of processed materials, strong crushing force, and it is widely used in limestone, iron ore, etc. The compressive strength does not exceed Various ores and rocks of 2500kg/cm2.
In the multi-stage crushing process, after rough crushing and fine crushing, the desired product is finally formed. This is a common crushing production line. If the output of primary crushing is greater than secondary crushing, or secondary crushing is greater than tertiary crushing, people usually think that primary crushing is good, while secondary crushing and tertiary crushing are not good. In fact, this is not the case, this is a typical selection mismatch caused by the process upside down. Therefore, when the multi-stage crushing process is arranged, the second bankruptcy volume should be considered slightly larger than the first bankruptcy volume, and so on, so that the process can be smooth. The feeding of the crusher is something that people easily ignore and ignore. The feeding of the crusher is related to the service life and the normal operating cycle of the crusher. The feeding must be uniformly fed. So be sure to follow the instructions and pay attention to the maintenance and maintenance of the crusher.
