附录A Cone Crushers

Cone Crusher is suitable to crush various kinds of ores and rocks of medium or above medium pared 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 overloading 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 chamber 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 crushes 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 and 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 theeccentric 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 descended 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 Construction 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 raises 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 capacity in relation to size. They have high reduction efficiency and give very good product shape. 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 productive. 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-service design makes them a perfect choice for mobile
