Types and characteristics of cone crushers
There are various types of cone crushers, each with its own unique characteristics.
Simons cone crusher is the most commonly used one in the world. It is inexpensive, has stable performance, and has a wide range of operation and maintenance experience. However, its structure is bulky, its crushing force is small, its output is low, and its iron-passing function is unreliable. It has gradually been replaced by more advanced models. Domestic manufacturers have added a hydraulic cavity clearing function to form a composite type.
The rotary disc cone crusher is suitable for the fourth stage of crushing of medium-hard materials. It can achieve lamination crushing and obtain smaller particle size products at a larger discharge port. It is often called an ultra-fine crusher. However, its energy consumption is high, the machine is bulky, and the output is low.
The single-cylinder hydraulic cone crusher has a simple structure, low manufacturing cost, stable performance, and is suitable for medium, fine and even ultra-fine crushing operations. Its characteristics include steep cone, high swing frequency, small eccentricity, and the main shaft is supported in the form of a simply supported beam, a single-cylinder hydraulic support at the bottom, and a star-shaped frame structure at the top. The crushed materials are uniform, there are fewer needle-like materials, and the crushing force and power fluctuations are small. However, the crushing force is slightly insufficient and is not suitable for crushing hard materials. In addition, the mortar wall wears unevenly when the feeding is uneven. The cylinder is at the bottom, resulting in a small lower working space, which makes maintenance difficult.
The multi-cylinder hydraulic cone crusher has the characteristics of high swing frequency, large eccentricity, and slow cone. The peripheral multi-cylinder hydraulic locking, the use of hydraulic motor to adjust the fixed cone, the crushing force is large, and it is suitable for crushing hard materials. However, the spherical radius is small, the swing radius is small, and there are unstable phenomena such as shaking, tipping and flying of the moving cone. The main shaft and the bushing are in poor contact, and the impact force is large, which affects normal work, but the processing capacity is relatively high.
