Application Of Vibrating Screens In Coal Preparation Plants

As a common coal and ore screening equipment, vibrating screens are widely used in coal preparation plants, and their main function is grading and sorting.

Application of vibrating screens in coal preparation plants

Coal is often affected by mud and other impurities during the coal preparation process, so pretreatment of the feed is necessary. By using a vibrating screen to separate coal into different sizes, impurities can be easily separated from the coal, making subsequent processing smoother. Vibrating screens can also classify coal according to different particle sizes to facilitate storage and logistics distribution.

Advantages of vibrating screens in coal preparation plants

1. High efficiency

Vibrating screens can efficiently separate coal of different sizes, effectively separating different coal types and impurities, thus improving the efficiency and quality of coal preparation.

2. Highly applicable

Vibrating screens can process various types of materials, including coal, ore, and building materials. In coal preparation plants, not all coal is uniform. Therefore, material grading is necessary, and vibrating screens can better meet this requirement.

3. Easy to operate and maintain

Vibrating screens are easy to operate. Different production needs can be met by controlling the vibration speed and adjusting parameters such as the screen mesh. Easy to maintain and service, reducing repair costs and downtime.

Disadvantages of vibrating screens in coal preparation plants

1. Screen clogging

The materials may contain some solid particulate impurities. After the vibrating screen has been running continuously for a period of time, this can cause the screen mesh to become clogged, thus affecting the screening effect. Manual cleaning is required.

2. Noise

Vibrating screens generate some noise when they are in operation.

Improvement measures

To overcome some shortcomings of vibrating screens in coal preparation plants, the following improvement measures can be taken:

1. Adjust the screen structure to reduce the probability of screen clogging.

2. Noise can be reduced by installing a hydraulic vibrator.

3. By monitoring the screening process, automated control can be achieved, thereby improving production efficiency.
