1、附录A Cone Crushers Cone Crusher is suitable to crush various kinds of ores and rocks of medium or above medium hardness.Compared with Jaw Crusher, Spring Cone Crusher is of stable structure, high efficiency, easy adjustment,and economical using etc. The spring safety system of crusher acts as an over

2、loading protection system that allows metals to pass through the crushing chamber so as not to damage the Cone Crusher. The safety system uses dry oil and water as two kinds of sealed formation to make plaster powder and engine oil separated to make sure reliable performance. This type of crushing c

3、hamber depends upon the size offeeding and fineness of the crushed product. The standard type (PYB) is applied to medium crushing, themedium type is applied to medium or fine crushing and the short head type is applied to fine crushing. Working Principle of Spring Cone Crusher: Spring Cone Crusher c

4、rushes materials by the working surface between the movable cone and fixed cone.So it is more advanced and efficiency than Jaw Crusher. The movable cone is supported by spherical bearing and fixed on an hanging erect shaft which is set in the eccentric sleeve, and the sleeve is set on the stopping a

5、nd pushing bearing. The movable cone and erect shaft are driven by the eccentric shaft sleeve together. The eccentric shaft sleeve is driven by horizontal shaft and fimbriated gear, and thwheelof the conveyor belt is driven by motor through v-belts. The lower part of vertical shaft is installed in t

6、heeccentric 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, grindedmaterials is discharged from the discharge hole. The fixed cone can be ascended or de

7、scended by adjusting setting to adjust the width of discharge hole; consequently the output Intense competition and strong fluctuations in the price of raw materials entail a constant endeavor by the mining industry to identify more energy and cost-efficient solutions. Sandvik Mining and Constructio

8、n is participating in this development to meet the demands of customers. A number of new products were launched in 2009, including an innovative solution for cone crushers. The Sandvik Flexifeed is a new type of mantle with a unique, patented design and functionality that boosts productivity and rai

9、ses the quality of crush material. The mantle offers better utilization of the crushing chamber and more uniform wear of the entire chamber, extending the service life by between 20 and 50%, depending on the application. Sandvik cone crushers are of advanced design with a small footprint and high ca

With hydraulically adjusted CSS, the option of automation, a choice of several different crushing chambers, and many other high-performance features, each model is versatile, user-friendly and highly pr

11、oductive. The Sandvik CS- and CH-series of cone crushers have a wide field of use as they can easily be matched to changes in production through the proper selection of crushing chamber and eccentric throw. Our cone crushers are ideal for secondary and tertiary crushing and the compact and easy-to-s

12、ervice design makes them a perfect choice for mobile installations. Our crushers provide automatic overload protection and can be equipped with our automatic setting system ASRi. This system optimizes cone crusher efficiency and automatically adapts the crusher to variations in feed conditions. By c

13、ontinuously measuring and compensating for crusher liner wear, ASRi allows you fully utilize crusher liners and schedule liner replacements to coincide with planned maintenance stops. ASRi also assists in keeping your crusher choke fed. This maximizes rock-on-rock crushing, which helps to optimize t

14、he quality of your final product. High Performance Lowest Total Cost The hydraulically adjusted CS & CH cone crushers manufactured by Sandvik are characterized by robust design and high performance. In combination with the CLP crushing chambers, high motor powers give these crushers capacities which

15、 are in most cases comparable with those of other, larger crushers. The CLP advantages are: Constant feed acceptance capability Increased output High-quality products Increased liner life Lowest total cost Sandvik cone crushers can be equipped with an automatic setting system, ASRi, which can improv

16、e performance even more and also provides integration with sophisticated plant control systems. CLP crushing chamber. CLP stands for Constant Liner Performance. The almost vertical profile of the feed opening area means that the shape of the chamber remains virtually unchanged throughout the wearing

17、 lifeExcellent Versatility Our cone crushers have a wide field of use. Several standard crushing chambers are available for each model. The crushers can easily be matched to changes in production through the proper selection of crushing chamber and eccentric throw. Sandvik cone crushers are an excel

18、lent choice as secondary crushers in combination with a jaw or a primary gyratory crusher or in the third or fourth crushing stage. Thanks to their built-in versatility, these crushers will enable you to cope with most production requirements in a changing future. Several standard crushing chambers

19、are available. The crushers can easily be matched to changes in production by the proper selection of crushing chamber and eccentric throw. Full Control of the Process The Hydroset system provides safety and setting adjustment functions, and incorporates a heavy-duty hydraulic cylinder which support

20、s the mainshaft and adjusts its position. The Hydroset system provides automatic overload protection to permit the passage of tramp iron or other uncrushable material. The system then automatically returns the mainshaft smoothly to its original position. When the cone crusher is equipped with our au

21、tomatic setting system, ASRi, the actual crushing load inside the crusher is continuously monitored. This makes it possible to optimize crusher utlilization allowing you to squeeze the ultimate performance from your machine at all times. The crushers can be equipped with ASRi, which monitors the loa
