Coal remains one of the world’s most abundant and essential energy sources. To make it suitable for energy production and industrial applications, raw coal must be processed, cleaned, and sorted properly. One of the most vital components of this process is the Vibratory Screen. These screening machines play a significant role in separating coal particles based on size, removing impurities, and optimizing the value of the final product.
Pics International offers high-performance Vibratory Screens designed to serve various industries, especially the coal sector. With years of experience in material handling and screening solutions, Pics International has developed robust systems that support primary, secondary, and tertiary screening. The 18° slope angle of the VS screens, adjustable to meet specific requirements, and the integration of spray pipes for wet screening make them particularly effective in coal processing.
Role of Vibratory Screens in Coal Processing
The primary role of a Vibratory Screen in the coal industry is to classify raw coal into different grades or particle sizes. This classification helps improve combustion efficiency, minimize emissions, and enhance the final product’s quality. Screening also removes contaminants like rock, shale, and clay, which are typically present in mined coal.
Coal is typically screened at various stages:
- Primary Screening: To remove oversized material right after crushing.
- Secondary Screening: To further refine the particle sizes for specific industrial requirements.
- Tertiary Screening: For ultra-fine separation and removal of minute impurities.
In each of these stages, Vibratory Screens allow mining and processing units to maintain quality standards and improve operational throughput.
How Vibratory Screens Work
Vibratory Screens use vibrational energy to move coal across the screen surface. The screens are equipped with mesh or perforated plates of varying sizes to allow particles below a specific size to pass through while retaining larger pieces. The motion generated by the vibratory motors causes stratification, which brings finer particles closer to the screen surface and pushes coarser particles upward. This natural stratification makes the screening process highly effective and accurate. Pics International’s Vibratory Screens are engineered to enhance this motion with optimized screen angle, stroke length, and vibration frequency.
Advantages of Vibratory Screens in Coal Industry
The coal industry demands rugged, efficient, and reliable equipment. Vibratory Screens offer the following benefits:
- High Screening Efficiency: Precise separation of coal particles by size.
- Low Maintenance: Minimal moving parts reduce wear and tear.
- Wet Screening Capability: Integrated spray pipes assist in cleaning and classifying coal with moisture or mud content.
- Energy Efficient: Vibratory motors consume less energy than mechanical alternatives.
- Versatility: Suitable for dry and wet screening applications.
Applications of Vibratory Screens in Coal Handling Plants
Coal handling plants in power stations and mines make extensive use of Vibratory Screens to manage and process raw coal. Some of the main applications include:
- Pre-treatment of coal to remove large rocks.
- Final separation to classify coal into multiple size fractions.
- Moisture removal when used in wet screening.
- Slurry separation in processing plants using hydrocyclone-supported systems.
