One of the most important parts of a hydrocone crusher is the hydrocone’s eccentric bush, which plays a key role in regulating the speed and size of the output load and controlling the crushing process. This bush, with a crank-like movement, transfers the speed and power necessary to crush the rocks to the central axis of the machine and brings the particles to the desired size. For this reason, this part is also called the hydraulic crank bushing.
Basic functions of the hydraulic eccentric bushing:
- Speed adjustment: The eccentric bushing allows precise adjustment of the mantle rotation speed and control of the speed of the grinding process by changing the speed of the main shaft. This enables the operator to produce a product with a uniform and desired size.
- Control of the output load size: By changing the size of the eccentric bushing, the distance between the mantle and the concave can be adjusted and the size of the output particles can be controlled. This gives the operator the flexibility to crush rocks to the desired size.
- Increase efficiency: The eccentric bushing, by creating a crank in the main shaft, gives the machine a smooth and vibration-free movement and reduces friction between components. This increases the crusher’s efficiency and effectiveness and optimizes energy consumption.
The effect of using a high-quality eccentric bushing in a hydrocone crusher
- Precise and uniform crushing: A high-quality eccentric bushing, by precisely adjusting the speed and size of the output load, helps produce a product with a precise and uniform size. This increases the final quality of the stones and reduces waste and scrap.
- Smooth and vibration-free operation: A high-quality eccentric bushing provides a smooth and vibration-free movement to the crusher and prevents unwanted noise and vibrations that can lead to operator fatigue and damage to other components.
- Long service life: A high-quality eccentric bushing has high resistance to wear and corrosion and requires less replacement and repair over time. This significantly reduces maintenance and repair costs and increases the crusher’s service life.
- Easy adjustment: The high-quality eccentric bushing provides the operator with easy adjustment and helps to change the speed and output load size quickly and easily.
Hydrocon eccentric bushing type
Hydrocon eccentric bushing is made of brass alloy. Unlike other hydrocon parts that are made of manganese steel, brass alloy is the superior choice for eccentric bushings due to its high malleability, wear resistance, and melting temperature of 900 degrees Celsius. These features significantly increase the useful life of the bush and prevent it from eroding and premature failure against hard and abrasive rocks.
In addition, the resistance of the brass alloy to weather changes makes this part an ideal option for use in various weather conditions. This ensures uninterrupted and flawless performance in any situation.
The choice of high-quality and high-quality materials for the manufacture of the eccentric bush, including brass ingots and special alloys, plays a major role.It plays a role in maintaining its efficiency and useful life. Using brass scrap not only leads to reducing the quality and performance of the bush, but also significantly reduces the useful life of the hydrocon device.
