Cone crusher is suitable for crushing various
kinds of ores and rocks of medium or above medium hardness. Cone
crushers have many features like stable structure, high efficiency,
easy adjustment, low operating cost and etc. The spring safety
system works as an overloading protection system which allows
metals to pass through the crushing chamber so as not to damage
cone crusher. The safety system adopts dry oil and water as two
kinds of sealed formation to make plaster powder and engine oil
separated to ensure reliable performance. The crushing chambers are
depending upon the feeding size and the fineness of final products.
The standard type(PYB) is applied to medium crushing; the medium
type is applied to medium or fine crushing; and short head type is
applied to fine crushing.
Working principle of Cone crusher:
Cone crusher crushes materials through the working surface between
the movable cone and fixed cone. The movable cone is supported by
spherical bearing and fixed on an hanging erect shaft which is set
in the eccentric sleeve, which is set on the stopping and pushing
bearing. The movable cone and erect shaft are drived 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 drived 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
are discharged from the diacharging hole. The fixed cone can be
ascended or descended by adjusting the width of discharging hole,
consequantly the output size is determined.
