Generally, when Zhengzhou Shibang Machinery sells jaw crushers, it will implement a three-guarantee policy and a one-year warranty for the whole machine, except for wearing parts. According to feedback from jaw crusher three-guarantee service feedback, it is common among users There is a wrong concept that the faster the speed of the jaw crusher, the higher the output, so the speed of the jaw crusher is increased arbitrarily, leading to some accidents.
The experiment proves that with the increase of the rotation speed of the jaw crusher, the power consumption per ton of material is also significantly increased (this is a key project indicator in quality supervision and inspection), and the output is also significantly lower, and the speed is restored to the original design speed The electricity consumption index per ton of material will reach the national standard, and the output will also increase. These facts fully show that the speed has a great impact on the energy consumption and output of the jaw crusher. Therefore, the jaw crusher needs a reasonably normalized speed. So what kind of number of revolutions is considered normal?
After research by Dolomite Crusher Provider In South Africa, on the same Hubei, with the speed increasing, the no-load power of Hubei Crusher increased geometrically. That is, the speed is doubled, and the no-load power is increased to 4 times. Conversely, if the speed is reduced by 1/2, its no-load power is also reduced to the original 1/4, thus revealing the inherent relationship between the energy consumption, output and speed of the jaw crusher. It reminds us that, in order to avoid wasting energy, when designing the crusher to select the rotation speed, as long as it can fully meet the impact of the crushing operation on the material being crushed, the lower the rotation speed, the better. This can not only save a lot of energy, but also reduce the vibration and noise of the machine, reduce the alternating stress on the spindle, reduce the centrifugal force on the rotor, extend the service life of the bearing, reduce unsafe factors, etc.
