Cone crusher is suitable 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 cone crusher. 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 (PYB) 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. Working Principle Cone crusher crushes materials by the working surface between the movable cone and fixed cone. So it is more advanced and efficiency efficient 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 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 movable 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 adjusted.Mode Cone Diametermm Feeding particle sizemm Exit adjustable scalemm Longest particlesmm Process Capacityt/h Eccentric bushingrotation (r/min) Powerkw Weightt YB600 600 75 12-25 65 40 356 30 5 PYD600 600 40 2-13 35 12-23 356 30 5.5 PYB900 900 135 15-50 115 50-90 333 55 11.2 PYZ900 900 70 5-20 60 20-65 333 55 11.2 PYD900 900 50 3-13 50 15-50 333 55 11.3 PYB1200 1200 170 20-50 145 110-168 300 110 24.7 PYZ1200 1200 115 8-25 100 42-135 300 110 25 PYD1200 1200 60 3-15 50 18-105 300 110 25.3 PYB1750 1700 250 25-50 215 280-480 245 160 50.3 PYZ1750 1700 215 10-30 185 115-320 245 160 50.3 PYD1750 1700 100 5-13 85 75-230 245 160 50.2 PYB2200 2200 350 30-60 300 590-1000 220 280/260 80 PYZ2200 2200 275 10-30 230 200-580 220 280/260 80 PYD2200 2200 130 5-15 100 120-340 220 280/260 81.4
