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.

Adjusting the hydraulic cylinder on the bottom of moving cone to let the cone move up and down can make the adjustment of the discharge port's opening easier, and, therefore, the granularity of final products can get better control. Besides, the hydraulic cylinder has a protection function when iron blocks intrude. If there are unbreakable materials such as iron blocks entering the crushing cavity, the hydraulic cylinder will drop the moving cone to release iron blocks while the crushing process doesn't stop.

    High Output Yet Low Crushing Costs

    A crusher's capacity depends on its crushing cavity to a great extent. HGT Gyratory Crusher has a delicate crushing cavity which brings optimal productivity, allows bigger feeding size and effectively extends the service life of lining plate. That the large dip angle and the long crushing surface combine with optimized stroke and speed can give the crusher super-strong crushing capability. HGT Gyratory Crusher can service for various coarse crushing demands. By only changing the eccentric bushing, the output can get adjusted.

    Able To Work Continuously Under High Intensity

    HGT Gyratory Crusher has a heavy-duty framework, an integrated large-dimension axis and high-precision bearings, so, undoubtedly, it has higher strength and longer service life, allowing it to work continuously and safely under high intensity. The heavy-duty framework can adapt any severe working situation while the integrally-forged axis and moving cone eliminate the risks that the cone gets loose during operation, which further shortens the downtime. The locking screw thread of the moving cone is on the replaceable axis bushing, not on the axis. In this way, the axis is free from stress concentration, and the strength can be higher.

    Simpler Operation And Maintenance

    Because the HGT Gyratory Crusher is supersized, how to make its maintenance get easier plays an important role. In light of this, SBM specially equips it with automated lubricating and hydraulic system. According to specific production conditions, the lubrication system can choose heating, cooling or circulation automatically. The configured automated axis' position controlling system can control the axis through the hydraulic system. It can help adjust the opening of the discharge port freely on one hand and compensate abrasion of the lining plate on the other hand. Through the external gear adjustment device, the side clearance of gear can get adjusted easily. The beam bushing and sealing can be replaced without dismantling the beam. When there is a need to dismantle the beam, users can equip a hydraulic beam separator.

    Efficient And Intelligent Production

    The HGT Gyratory Crusher adopts the automated control system. It is equipped with various types of sensors to monitor the lubrication pressure and temperature, the bearing temperature, the rotation speed and the axis' position, a PLC as well as a touch screen. By these, every production stage can be monitored, displayed and controlled in real time. Besides, the automated control system can also optimize the working parameters of configured devices according to actual operation conditions to increase production efficiency.

    Strong Adaptability, Applicable For Severe Crushing Conditions

    Whether being used in fixed or semi-mobile crushing lines, on ground or underground, HGT Hydraulic Gyratory Crusher is applicable in severe crushing environment. It is able to crush various hard and abrasive ores and rocks.

    Sufficient Supply Of Spare Parts, Worry-Free Operation

    SBM, whose businesses cover production and sales, takes responsibility for every machine produced by ourselves. We can offer customers technical services about products and original spare parts to ensure the worry-free operation.

 

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.
