Research on the Influence of Material Moisture on the Performance of PE Jaw Crushers in Metal Mine Crushing Processes

In the realm of metal mine primary crushing, the PE jaw crusher stands as a cornerstone equipment. With over thirty years of industry experience, Zhengzhou Kuanglian Machinery has been at the forefront of providing global services and customized solutions for this equipment. This article delves deep into the key technical advantages and application pitfalls of the PE jaw crusher, with a particular focus on the impact of material humidity on its performance.

Technical Advantages of PE Jaw Crusher

The PE jaw crusher boasts several remarkable technical features. First, its moving jaw swing trajectory design is a masterpiece of engineering. This design allows for a more efficient crushing process, increasing the crushing force and reducing energy consumption. For example, compared with traditional crushers, the energy consumption of the PE jaw crusher can be reduced by about 20 - 30% under the same working conditions.

Secondly, the high - strength cast steel eccentric shaft is another highlight. It can withstand high - intensity loads, ensuring the long - term stable operation of the crusher. The service life of this eccentric shaft can reach more than 10 years under normal use conditions, which greatly reduces the replacement cost for users.

In addition, the adjustable discharge port system provides users with greater flexibility. Users can adjust the discharge port according to different production requirements, thereby controlling the particle size of the crushed materials. This feature enables the crusher to adapt to a wider range of production scenarios.

Common Application Mistakes

However, in the actual use process, there are several common mistakes. One of the most prominent is the blind pursuit of a high crushing ratio. Some users believe that the higher the crushing ratio, the better the performance of the crusher. But in fact, an overly high crushing ratio may lead to an increase in energy consumption and a decrease in the service life of the equipment. According to real - world engineering data, when the crushing ratio is increased by 50%, the energy consumption of the crusher may increase by about 40%, and the wear of key components may double.

Another mistake is ignoring the impact of material humidity. When the material humidity is too high, it can cause the materials to adhere to the inner wall of the crusher, reducing the crushing efficiency and even causing blockages. For instance, when the material humidity exceeds 15%, the production capacity of the crusher may be reduced by about 30 - 40%.

Lack of regular maintenance is also a common problem. Without proper maintenance, the performance of the crusher will gradually decline. For example, if the lubricating oil is not replaced regularly, the friction between components will increase, resulting in increased energy consumption and potential damage to the equipment.

Solutions and Suggestions

To address these issues, users should adjust the discharge port scientifically. They can refer to the material characteristics and production requirements to determine the appropriate discharge port size. At the same time, they should pay attention to the material humidity. When the humidity is high, appropriate drying measures can be taken to ensure the normal operation of the crusher.

Regular maintenance is also crucial. Users should establish a complete maintenance plan, including regular inspection of key components, replacement of lubricating oil, and cleaning of the crusher. By doing so, the service life of the crusher can be extended, and its performance can be maintained at a high level.
