Single cylinder hydraulic cone crusher

Description

Single cylinder hydraulic cone crusher (single cylinder cone crusher) is a high efficiency crusher designed by our company to meet the needs of developing countries by introducing American technology and combining the performance of Chinese metal materials. Because of the special design structure of the single cylinder at the bottom, it can complete the three important functions of direct adjustment of the discharge port, prevention of over-iron, and clearing of the cavity, so there is no external adjustment mechanism of the discharge port, external hydraulic cylinder or anti-over-iron device of the spring, and the overall shape is simple and compact.

Single cylinder hydraulic cone crusher is a single hydraulic cylinder lifting cone, can realize the adjustment of ore discharge port, cavity cleaning and overload protection functions; Coupled with the configuration of electronic intelligent discharge port control system, more automated production can be realized, and can be widely used in various black, nonferrous, non-metallic mines and sand and stone and other industrial fields.

Performance Advantages

• 1, single-cylinder hydraulic cone crusher spindle both ends are supported, can withstand greater crushing force and greater stroke.
• 2, equipped with a special crushing chamber shape adapted to the lamination principle, so that the machine has a higher crushing efficiency.
• 3, the single cylinder hydraulic cone crusher crushing stroke, crushing speed and the shape of the crushing chamber is a good combination of design, so that the machine in the moving cone big end diameter is the same, the output is higher than the old spring cone breaking 35%~60%.
• 4, a variety of cavity shape of the fine crushing, only need to replace the fixed cone can be achieved.
• 5, double safety control of hydraulic and lubrication system, can ensure the machine overload protection and good bearing lubrication.
• 6, high technology hydraulic technology, to achieve overload protection and hydraulic adjustment of the discharge port, simplify the crusher structure, reduce the weight.

Working Principle

When the single-cylinder hydraulic cone crusher (single-cylinder cone crusher) is working, the motor drives the pinion of the crusher, the pinion drives the big gear, the big gear assembly (big gear, big gear frame, eccentric steel sleeve) drives the eccentric sleeve assembly (eccentric cylinder liner, eccentric copper sleeve) and the main shaft assembly (spindle, inner cone, inner cone liner) to the theoretical vertical line as the center, in the copper bushing revolution, The spindle assembly can realize rotation with the center line of the spindle in the eccentric copper sleeve.

When the air machine is running, the eccentric sleeve assembly "holds" the spindle assembly and rotates with the big gear. When the material is added to the crushing chamber, the spindle assembly (spindle, inner cone) slowly rotates in the eccentric copper sleeve under the resistance of the material. The movement trajectory of the inner cone appears to swing back and forth in the crushing chamber, while slowly rotating, the material is crushed by the swinging inner cone.

The connection between the support sleeve and the frame body is pressed tightly by the hydraulic cylinder. When the crusher falls into the metal block and other unbreakable objects, the moving cone of the single cylinder is lifted by the hydraulic piston at the bottom, which plays the role of adjustment of the discharge port and over-iron protection.

Question&Answer

Q：Cone crusher "speed" how to do?

A：Solution: Ensure the assembly clearance of the inner and outer holes of the cone sleeve and the contact between the spindle and the cone sleeve along the full length, and the cone sleeve and the shaft sleeve must be fixed with melted zinc alloy to ensure that there is no relative movement between the two.

Q：What causes the moving cone to lift?

A：In winter, the oil temperature is too low and the safety valve fails, so that the oil supply pressure is too high, the capacity of the oil pump is too large, and the moving cone will be lifted in these three cases.
Solution: Preheat lubricating oil in advance, check and adjust the safety valve in time, and replace the oil pump.
