The working principle of the cone crusher is that the rotation of the electric motor through the pulley or coupling, the drive shaft of the cone crusher and the cone of the cone crusher are forced by the eccentric sleeve to make a swinging motion around a fixed point. This causes the crushing wall of the crushing cone to move closer to and away from the surface of the wall of the cone, which is fixed on the adjustment sleeve, so that the ore is continuously impacted, squeezed and bent in the crushing chamber to achieve the crushing of the ore.  　　The cone crusher spring machine and the single cylinder machine both rely on the discharge port to control the size of the crushed product. This inevitably results in a small discharge opening for small size products, resulting in a significant drop in crusher output and easy clogging. This contradiction is solved by increasing the discharge opening, increasing the swing range and increasing the cone speed. In the case of fine crushers, where there is no over compaction, but there is sufficient density, an increase in the swing range is required. The larger the swing of the cone, the er the degree of compaction and the larger the discharge opening. This increases both the crusher output and the fines content of the product. Tests have also shown that the fines content and fineness increase significantly with the degree of compaction.
　　When compressing the material in the crushing chamber of the cone crusher, it is important to have sufficient compaction and a high compression ratio to obtain both a high output and a significant increase in the fines content. To ensure a high compression ratio, it is necessary to have a reasonable cavity shape and reasonable structural and operating parameters to match this cavity shape. To ensure a high compression ratio, there be enough ore volume in the cavity. Adopting high swing frequency and large swing range, so that when the moving cone withdraws to the end and returns, it encounters the falling material and can scatter it, and then carry out interlayer crushing.
