1750型彈簧式圓錐破碎機的工作原理是電動機通過驅動皮帶和皮帶輪，通過傳動軸、大齒輪、小齒輪帶動主軸運動，當主軸轉動時，帶動偏心軸轉動，從而使推動錐偏心轉動，同時物料被壓破，達到破碎的目的；當礦石達到破碎的要求尺寸時，礦石從動錐大端排料口排出。隨著電動機連續轉動同時也帶動主軸做偏心轉動，實現連續生產。

1750型彈簧式圓錐破碎機的組成結構主要有機架、主軸、傳動軸、大帶輪、大齒輪、小齒輪、動錐、定錐、內襯板、錐套、調整環、清腔千斤頂、防松裝置保護裝置等組成，其中肘板還起到保險作用。

Spring cone crusher main frame structure, spindle,drive shaft, the

pulley, big gear, small gear,moving cone, fixed cone lining board sleeve, adjusting the ring,money jack cavity, anti-loose device protection devices, etc., ofwhich insurance bracket also play a role.
Spring cone crusher working principle is the motor-driven belt andpulley passed through the shaft, big gear, small gear drivenspindle movement, when the spindle rotation, the eccentric driveshaft rotation, thus promoting the eccentric rotating cone, at thesame time material was pressure broken, broken to achieve thepurpose; when broken ore to meet the requirements of size, the oreon the big-cone driven from nesting population. With the motordrive for rotating the spindle at the same time so eccentricrotation, to achieve continuous production.
The design of the cone crusher for spring design calculations andstructural design, primarily eccentric shaft, transmission shaft,fixed cone, the size of gears, pulleys and so on. To determine thestructure of the major dimensions, after a design drawing of thetotal assembly drawing and parts drawing eccentric shaft.
Keywords: cone crusher spring design, the structuraldesign.
