Short Head Symons Cone Crusher

Product Description:
LY Spring cone crusher adopts the international advanced techniques to develop this equipment. Designed on layered crushing theory, with overload hydraulic cavity cleaning system and lubrication system with refrigerants fully ensure the safety and stability during operation. With hydraulic push cylinder and look cylinder to adjust the discharge opening width by hydraulic system. Invent and adopt the techniques of with concave holder & concave and crushing cone surface to instead the anciently complicated techniques. Cone crusher is applicable to break various ores and rocks with medium or above hardness and widely used in metallurgical, architectural, road & railway building. It's ideal for secondary crushing.
Advantages:
1) Larger crushing ratio,
2) Excellent product shape
3) Reliable, safe and stability operation
4) High production efficiency/capacity
5) High reliability, low running cost
Product Special Features:
1). Continuous rotating of movable cone; continue unloading of materials during the crushing process alternately along the work surface, high production efficiency and capacity,
2). Material is extruded in two cones, squeezed and bended, which can low power consumption.
3). Cubic product shape and the cones surface is more uniform wear
4). Main structures is consist of main body, the horizontal axis, movable cone, balancing wheels, eccentric shaft bushing, fixed cone, dynamic cone, fluid couplings, lubrication systems, hydraulic system, control system, etc.
5). Dynamic cone and fixed cone is upright. There is a gap parallel with the crushing discharge chamber when the movable cone swinging, which make uniform products. The feed edge is not big enough, so the material after primary crushing is suitable for crushing.
6). This series cone crusher adopt dry-oil and water seal way, which protect from dust and impurities entering the body, thus extending the service life of the sliding bearing and the thrust ball bearings to ensure the reliable operation.
Application of Spring Cone Crusher
Spring Cone Crusher is suitable to crush various kinds of ores and rocks of medium or above medium hardness. Compared with Jaw Crusher, Spring Cone Crusher is of stable structure, high efficiency, easy adjustment, and economical using etc. The spring safety system of crusher acts as an overloading protection system that allows metals to pass through the crushing chamber so as not to damage the Cone Crusher. The safety system uses dry oil and water as two kinds of sealed formation to make plaster powder and engine oil separated to make sure reliable performance. This type of crushing chamber depends upon the size of feeding and fineness of the crushed product.
The standard type (PYB) is applied to medium crushing, the medium type is applied to medium or fine crushing and the short head type is applied to fine crushing.
Structural Drawing

Working Principle
During operation, the motor drives the eccentric bushing to run via the belt, drive shaft and a couple of bevel gears. The axial lead of the crushing cone swings under the enforcement of the eccentric bushing so that the surface of concavel approaches and leaves the surface of the rolling wall by turns. Thus the ores within the crushing chamber are crushed under the constant compression and bending.
