Eccentric static torque , nesting space, shaker speed and shape of the crushing chamber is cone crusher operating parameters. Test proved : By adjusting the operating parameters of the crusher , can cause certain effects on the crusher performance indicators, such as production , function, product size , etc., so that we can meet the various needs of different materials. Today, as we explain the impact of the first exciter speed and cavity pressure on the performance indicators. First: the cone crusher shaker speed increases, reducing the yield of the product will also reduce the average particle size is mainly due to a larger shaker speed , the number of impact crushing , increase in the number of broken so also increases when the crushing force , reducing the weighted average particle size of the product product . When the exciter speed is increased , improving the dynamic cone rotary pendulum frequency discharge resistance also increases , reducing the yield, but with the increase of the speed of the exciter , broken off by the square raised, resulting in moving cone amplitude increases, increase the exciter is reduced resulting impact on yield.     Second: cone crusher crushing pressure increases , the density of the material layer is also increased, so that the material particles to obtain sufficient crushing, yieldis improved.
