HGT Gyratory Crusher

The gyratory crusher is a large-scale crushing machine that uses crushing motion of the crushing cone in the cone cavity of the casing to cause extrusion, splitting and bending of the material, and coarse crushing of ore or rock of various hardnesses.The upper end of the main shaft equipped with the crushing cone is supported in the bushing in the middle of the beam, and the lower end is placed in the eccentric hole of the bushing. When the sleeve rotates, the crushing cone rotates around the center line of the machine, and its crushing action is continuous, so the working efficiency is higher than that of the jaw crusher.

introduction of HGT Gyratory Crusher

The gyratory crusher realizes the adjustment of the discharge opening and the overload insurance in two ways: First, the mechanical method is adopted, and the upper end of the main shaft has an adjusting nut, and the rotating adjusting nut can be lowered or raised, so that the discharge opening is followed. Larger or smaller, when overloaded, the insurance pin on the drive pulley is cut to achieve insurance; the second is a hydraulic hydraulic gyratory crusher whose main shaft is located on the plunger in the hydraulic cylinder, changing the plunger The volume of the hydraulic oil can change the upper and lower positions of the crushing cone, thereby changing the size of the discharge opening. When overloaded, the downward pressure of the main shaft increases, forcing the hydraulic oil under the plunger to enter the accumulator in the hydraulic transmission system, causing the crushing cone to descend to increase the discharge opening and discharge the non-material entering the crushing chamber. Broken objects (iron, wood, etc.) to achieve insurance.

HGT Gyratory Crusher working principle

The upper end of the main shaft equipped with the crushing cone is supported in the bushing in the middle of the beam, and the lower end is placed in the eccentric hole of the bushing. When the sleeve rotates, the crushing cone rotates around the center line of the machine, and its crushing action is continuous, so the working efficiency is higher than that of the jaw crusher. By the early 1970s, large gyratory crushers were able to process 5,000 tons of material per hour, with a maximum feed diameter of up to 2000 mm. The gyratory crusher realizes the adjustment of the discharge opening and the overload insurance in two ways: First, the mechanical method is adopted, and the upper end of the main shaft has an adjusting nut, and the rotating adjusting nut can be lowered or raised, so that the discharge opening is followed. Larger or smaller, when overloaded, the insurance pin on the drive pulley is cut to achieve insurance; the second is a hydraulic hydraulic gyratory crusher whose main shaft is located on the plunger in the hydraulic cylinder, changing the plunger The volume of the hydraulic oil can change the upper and lower positions of the crushing cone, thereby changing the size of the discharge opening. When overloaded, the downward pressure of the main shaft increases, forcing the hydraulic oil under the plunger to enter the accumulator in the hydraulic transmission system, causing the crushing cone to descend to increase the discharge opening and discharge the non-material entering the crushing chamber.

advantages of HGT Gyratory Crusher

The gyratory crusher and the funnel cone crusher are all one type of cone crusher. The gyratory crusher is a coarse crusher. Compared with the jaw crusher, the crushing process is continuous along the circular crushing cavity, so the productivity is high and the power consumption is low. Work is smooth. Suitable for crushing sheet materials. Visible from the finished product size distribution curve. In the particle size composition of the finished product, the material size exceeding the width of the discharge port is smaller than that of the jaw crusher, and the number is small, and the particle size is relatively uniform. In addition, the original material can be poured directly from the transport into the feed port without the need for a feeder. The disadvantage of the gyratory crusher is that the structure is complicated. The price is higher; the maintenance is more difficult, the repair cost is large; the fuselage is higher, which increases the cost of the building, foundation and other structures.
The gyratory crusher is suitable for use in large production plants and mining yards. According to experience, if a jaw crusher can meet the production requirements when selecting the type, use the squat type; if two shovel types are required, consider a gyratory crusher.

1. Large Capacity And Low Cost Broken

  • (1) The gyratory crusher has a fine crushing chamber design to ensure greater production capacity, larger feed size and longer liner life;
  • (2) The gyratory crusher adopts the design of large inclination angle and long fracture surface, and cooperates with the optimized design stroke and rotation speed to make the crusher have super breaking capacity, which is suitable for various coarse crushing operations;
  • (3) The gyratory crusher can change the processing capacity of the crusher by simply replacing the eccentric sleeve to meet different crushing process requirements;

2. Continuous High-Intensity Work

  • (1) The gyratory crusher has an ultra-heavy frame, a large-diameter integral spindle and a high-precision cast bearing. The whole machine has higher strength and longer service life, ensuring safer and more reliable continuous high-strength production;
  • (2) The high-strength and extra-heavy frame design of the gyratory crusher can be applied to harsh production conditions to ensure safe and trouble-free operation;
  • (3) The main shaft and moving cone of the crusher are integrally forged to avoid loosening of the moving cone during use, reducing downtime, and the moving taper locking thread is located on the replaceable spindle sleeve. The spindle has no thread and no stress concentration, and the strength is higher.

3. Simpler Operation And Maintenance

  • (1) As a super large-scale equipment, the gyratory crusher pays special attention to the convenience of maintenance and design, and is equipped with automatic lubrication and hydraulic system. The lubrication system can automatically lubricate heating, cooling and circulation according to the production conditions;
  • (2) The gyratory crusher is equipped with an automatic spindle position control system, which can control the spindle through the hydraulic system, which is convenient for adjusting the size of the discharge port, and can compensate the wear of the liner and control the product granularity;
  • (3) The gyratory crusher can easily adjust the gear side clearance by the external gear adjustment device. The beam bushing and the seal can be replaced without removing the beam. When the beam needs to be disassembled, the hydraulic beam separator can be configured;

4. Efficient And Intelligent Production Process

  • (1) The gyratory crusher adopts an automatic control system, which is equipped with various sensors such as lubrication pressure, lubrication temperature, bearing temperature, speed, spindle position, etc., and configures PLC and touch screen to realize detection and control of each link of the equipment and display in real time;
  • (2) The gyratory crusher can automatically diagnose operational faults and record equipment production information. The automatic control system can not only control and protect equipment operation, reduce equipment maintenance cost and downtime, improve equipment operation rate, but also according to equipment operation. Optimize the working parameters of the equipment, improve the production efficiency of the equipment, and ensure stable, efficient and low-cost production of the equipment;

5. Strong Applicability, Can Be Used For Extreme Crushing Purposes

The gyratory crusher can be used for extreme crushing applications, whether it is fixed or semi-mobile, ground or underground, and can easily crush a variety of hard and abrasive rocks and ores. It is a new construction and upgrade project. An integral part of it
