Working Principle

HGT Gyratory Crusher is mainly composed of the beam, frame, moving cone, eccentric sleeve, transmission part and hydraulic cylinder. Driven by the motor, the horizontal shaft starts to rotate which then further makes the eccentric sleeve rotate under the assistance of gear. Next, the eccentric sleeve drives the moving cone to swing in a circular motion to squeeze and crush rocks continuously.

Advantages and Disadvantages of Gyratory Crusher

Neither machine is particularly well suited to handling very soft, or “mushy” materials, although the jaw crusher is superior to the gyratory for such service. Loosely cemented minerals, such as soft sandstone, will not work well in the gyratory crusher; packing on the diaphragm behind the pipe is almost certain to cause trouble. The jaw crusher will handle rock of this character if it is reasonably free-flowing. The action on all very soft materials is inclined to be sluggish and, unless it is at the same time of a free-flowing nature, packing in the crushing chamber is an ever present hazard.
The jaw crusher will handle rock and ore containing a considerable proportion of loam, or similar contamination, provided that the admixture is not so viscous that it builds up on the jaw plates. The gyratory should never be used for materials containing more than a small percentage of such contamination, the allowable amount being that which the clean crushed rock will keep scoured off of the diaphragm. Flushing the diaphragm will prevent packing of this dirty material, but this practice is usually not permissible in the crushing plant.

We have had occasion to use the expression, “comparable sizes,” a number of times in this work, with reference to comparisons between two types of crushers, particularly the jaw and gyratory types. This expression has been used by many writers on the subject; usually without any attempt to define exactly what it implies. As a matter of fact, it is a difficult term to define with any degree of accuracy. The Old Quarryman says, “It means two machines, one of which you would buy if you didn’t buy the other one, providing you had enough money to buy either one of them.” That comes about as near as any definition. Comparable sizes of gyratory and jaw crushers are those sizes which the engineer or operator pairs off against each other when making a selection to fit his specific problem, and these pairings may not be the same for all problems. One job may involve capacity as the most important factor; the next one may demand special emphasis on receiving opening. Obviously these different requirements may call for setting up a comparison between different sizes of one or the other type.

Usually, in selecting the primary crusher, receiving opening is the prime consideration; admitting of course that capacity must be adequate. The following list is an attempt to pair off gyratory and jaw crushers on the basis of effective receiving openings, bearing in mind that each shape of opening has its advantages for certain shape-characteristics of the feed, as has been pointed out.
