Coal mine screening helps separate coal from impurities such as rock, dirt, and other contaminants. Effective screening is essential to ensure that the coal is of high quality. Inefficient screening can lead to a range of problems, including:
Reduced coal quality
Increased maintenance costs
Decreased production efficiency
Higher energy consumption
Environmental concerns

The Challenges of Traditional Screening Methods:
Traditional screening methods, such as vibrating screens and trommels, have been used in coal mining for decades. However, these methods have several limitations, including:
High energy consumption
Limited screening efficiency
High maintenance costs
Noise pollution
Limited flexibility

Parabolic screen filters are an effective screening solution for coal mine industries. 

Parabolic Screen Filter, Curved Screen, for Coal Mine Screening


A parabolic screen filter is a coal mine screening equipment designed to separate particles based on size and density. Unlike traditional flat screens, the parabolic design offers a curved surface that enhances the screening efficiency. This curvature creates a more dynamic screening action, allowing for better separation and higher throughput.

How Parabolic Screen Filters Work

Parabolic screen filters consist of a series of curved screens arranged in a parabolic shape. The coal is fed into the top of the filter, where it is subjected to a series of gentle vibrations. The coal then passes through the curved screens, which separate the coal from impurities based on size and density. The clean coal is collected at the bottom of the filter, while the impurities are rejected.

Application for Parabolic Screen Filters in Coal Mine Screening

▪ Primary Screening: In the initial stages of coal processing, the filter efficiently removes oversized materials, ensuring that only appropriately sized particles proceed to the next stage.
▪ Fine Screening: For separating fine particles and impurities, the Parabolic Screen Filter offers superior performance, enhancing the quality of the final product.
▪ Dewatering: The filter can also be used in dewatering applications, where it helps remove excess moisture from coal particles, improving their handling and transport efficiency.

We can provide various sizes and types of parabolic screen filters for coal mine screening.
