All-Round Introduction of Spring Cone Crusher

     Spring cone crusher is crusher which is the earliest appearance in the world, and it is used widest and larger quantity crush mechanism at present. The Spring crusher is generally used as a secondary crusher in a stone production line, it is used to crush various kinds of ores and rocks of medium or above medium hardness. Compare with jaw crusher, cone crusher is of stable structure, high efficiency, easy adjustment, economic operation, etc.The spring safety system of crusher acts as an overloading protection system that allows metal to pass through the crushing chamber so as not to damage the machine. The safety system uses dry oil and water as two kinds of sealed formation to make plaster powder and engine oil separate to make sure reliable performance. The type of crushing chamber depends upon size of feeding and fineness of crushed product. The standard type is applied to medium crushing, the medium type is applied to medium or fine crushing and the short head type is applied to fine crushing.
      With the development of the series of spring crusher, its structure is more perfect than before and the technology parameter is more advanced, so these crushers have excellent performance in the aspects of manufacture, installation, use and maintenance etc. The spring crusher belongs to the machine, in the stone production line, there are some other crushers such as jaw crusher, impact crusher, vibrating feeder and vibrating screen.

     Spring cone crusher is widely used in industries like metallurgy, construction, road building, chemistry etc, to crush many kinds of mid-hard or hard rocks and ores such as iron ore, limestone, granite, basalt, quartz etc. The standard spring machines are used for secondary crushing; the medium ones are used for fine crushing; and the short head ones are used for super thin crushing. The spring cone crusher is characterized by a reliable structure, high efficiency, easy adjustment and economic. The spring safety system prevents overload so that hard materials (such as iron) are processed through the crushing chamber without damaging the machine. Spring machines are run on belt drives driven by an electric motor or diesel engine. Cone crushers are used extensively throughout the aggregate and mineral processing industry.

The working principle of spring cone crusher:
   spring cone crusehr crushes materials by the working surface between the movable cone and fixed cone. So spring cone crusher is more advanced and efficiency. The movable cone is supported by spherical bearing and fixed on an hanging vertical shaft which is set in the eccentric sleeve, and the sleeve is set on the stopping and pushing bearing. The movable cone and vertical shaft are driven by the eccentric shaft sleeve together. The eccentric shaft sleeve is driven by horizontal shaft and fimbriated gear, and the wheel of the conveyor belt is driven by motor through v-belts. The lower part of vertical shaft is installed in the eccentric sleeve. When the eccentric sleeve rotates, there is a conical surface lined out by the shaft. When the movable cone comes near the fixed cone, rocks are grinded into pieces, when the cone leaves, grinded materials is discharged from the discharge hole. The fixed cone can be ascended or descended by adjusting setting to adjust the width of discharge hole, consequently the output size is determined.

   Compared with jaw crusher, spring cone crusher has the advantage of low operation costs, high productivity, easy adjustment and stable structure. The spring cone crusher has higher capacity and the products with high quality. Because spring crushing machine has safety device, the parking time has been reduced greatly.
