Detailed Description of Cone Crusher:
The cone crusher is suitable for use in a wide range of applications that involves ores and rocks of medium hardness and above. As compared to the jaw crusher, the cone crusher has the advantage of having a stable structure, high efficiency, easy adjustment, and economical operation. The machine is fitted with a spring safety system that ensures that there is no damage inflicted on the cone crusher during the passage of metal through the cone crusher. The safety spring system protects the cone crusher against overloading. The crushing chamber is chosen according to the size of the materials being crushed as well as their degree of fineness. For crushing materials of medium hardness, the PYB type (standard type) machine is used. Fine materials are effectively crushed using the short head type.

The main crusher used in a mine or ore processing plant is the gyratory cone crusher which can be used for both primary and secondary crushing. Gyratory cone crushers are designated sizes according to the gape and mantle diameter or by the size of the receiving opening.

There is a gap between the mantle line (movable) mounted in the central vertical spindle and the concave liners (fixed) mounted in the main frame of the crusher. Cone crush machine crushes rocks and ores by closing the gap. The opening and closing of gap is made by an eccentric on the bottom of the spindle which caused the central vertical spindle to gyrate. The vertical spindle is free to rotate around its own axis.

The crusher illustrated refers to the short-shaft suspended spindle type. The differences between short-shaft suspended spindle type and long-shaft type is that the main shaft of the former is suspended at the top and that its eccentric is mounted above the gear.

Application of Cone Crusher
Our cone crusher can be used in construction, road building, metallurgy, chemical and phosphatic industry, etc.
It can crush iron ores, copper ores, limestone, quartz, granite, fritstone, and rocks and ores of medium and low hardness.
The crushing cavity type is determined by the application of the ores. For PYZ (secondary crush), standard type machine is used while for PYD (teriary crush), the middle type machine is used. The short-head type is used for primary and secondary crushing.

Structure and Operation Principles of Cone Crusher
1. The cone crusher is made up of a frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone, springs, and hydraulic pressure station for adjusting the discharge opening.
2. While in operation, the eccentric shaft shell is rotated by a motor through a horizontal axle and a pair of bevel gear. Under the eccentric shaft shell drive, the axle of crushing cone swings. When it swings to the extent that the surface of the crushing wall is close to the roll mortar wall, the rocks and ores are pressed and crushed.
3. Cone crusher is more advanced and efficient than the jaw crusher. This is because the cone breaker crushes materials using the working surface between the moveable cone and fixed cone.
Supported by spherical bearing, moveable cone is fixed on an erect hanging shaft. The erect shaft is set in the eccentric sleeve. The rotation of the eccentric shaft sleeve causes the movable cone and erect shaft to rotate accordingly.
Since the lower part of vertical shaft is installed in the eccentric sleeve, the rotation of the eccentric sleeve will create a conical surface. Rocks are crushed, when the moveable cone is close to the fixed one, and are discharged when they part.
4. The wheel of conveyor belt is driven by a motor through V-belts.
5. The size of final products can be determined through adjusting the width of discharge hole.

As a professional cone crusher manufacturer in China, Henan Hongji produces high-quality cone crushers with high productivity, easy maintenance and low cost, etc. Our cone breaker has a strong crushing ability in primary, secondary and tertiary crushing.
Our cone crushers and other products have gained ISO9001:2000 quality system certification and SGS certification. They are sold to Vietnam, Bengal, Myanmar, Laos, Peru, Philippines, Iran, India and other countries.
