Analysis the Parameters of Impact Crusher Rotor Speed

In order to reasonably determine the structure parameters and operating parameters of the impact crusher, we carried out the impact of changes in the speed of the rotor line product granularity the disc - Hammerhead layers product granularity.

The higher the line speed of the rotor, the finer granularity of product, and broken than the v = 35.4m / s,-1mm products accounted for 87.2%, crushing ratio of up to 21 studies disc - Hammerhead layers The product granularity relationship is an important basis to simplify the structure of the machine, reducing the weight of the machine. Impact Crusher is a multi-stage crushing equipment, impact - the number of extrusion broken with increasing the number of layers increases. V = 18.8m / s, and 28.3m / s under two conditions in order to determine the number of layers of the product particle size, determined in a certain line speed of the rotor disc - hammerhead Floors respectively, changing the number of layers and give into the 20 ~ 10mm limestone. Product particle size sieve analysis results by running test will be drawn into negative cumulative curve of the disc - hammerhead layers and product size relationship.

By the product particle size distribution curve can be seen, when the line speed of the rotor at 18.8m / s, when the number of layers is four or more, negative cumulative yield changes rarely; when the line speed of the rotor at 28.3m / s roller mill for sale, the number of layers in the more than five negative cumulative yield without much change. This shows that at a fixed speed, hammer impact force generated at a constant value, and the product size reaches certain fineness, the...
