When the spring cone crusher is working, the motor drives the large bevel gear at the bottom of the eccentric sleeve through the hydraulic coupler and the small bevel gear, so that the eccentric sleeve rotates, causing the cone to rotate and break the material. The main shaft of the crusher is not moving, only the dust spherical tile, bearing the crushing force. Because the crusher spindle is not moving and the eccentric sleeve transmits the crushing force, the structure can withstand the larger crushing force, and is very suitable for fine crushing and ultra-fine crushing, because the crushing force of ultra-fine crushing is very large. It is expected that the product particle size (for ultra-fine crushed liner) can reach 50-80% when open (depending on the nature of the material). The crusher is suitable for the third section crushing in metal mine concentrator, or the fourth section crushing; Suitable for building materials or non-metal mines and civil engineering. Especially in areas where natural sand for civil engineering is in short supply
