What is CHPP?
CHPP stands for Coal Handling and Preparation Plant. It is a facility that washes coal of soil and rock, crushes it into graded sized chunks, stockpiles grades preparing it for transport to market. A CHPP may also be called a coal handling and preparation system (CHPS), coal handling plant, prep plant, tipple or wash plant.
How does a CHPP work?
A CHPP is designed to receive coal from the underground mines, process it, and deliver it to the market. The process begins with the arrival of coal at the plant, either via trucks or conveyors. The coal is then stored in stockpiles to ensure a continuous supply throughout the year.
Once the coal is ready to be processed, it goes through several stages in the CHPP. The first stage is coal crushing, where large chunks of coal are broken down into smaller pieces. This is done to increase the surface area of the coal, making it easier to handle and process.
After crushing, the coal is then screened to separate it into different sizes. The sized coal is then washed to remove impurities such as rocks, clay, and other minerals. This process, known as coal washing, helps improve the quality of the coal and reduces its environmental impact when burned.
Once the coal is washed, it is then dewatered to remove excess water. This is done using various techniques such as centrifuges, filters, or thermal dryers. Dewatering helps reduce the moisture content of the coal, making it easier to handle and transport.
After dewatering, the coal is loaded onto trucks, trains, or barges for transportation to the market. The coal may also be stored in stockpiles at the plant or at a nearby location to ensure a continuous supply to customers.
Why is CHPP important?
CHPP plays a crucial role in the coal mining industry. It helps improve the quality of coal by removing impurities and ensures a consistent supply to the market. The process of coal washing in a CHPP helps reduce the environmental impact of coal by removing harmful substances before combustion.
Additionally, a well-designed CHPP improves the efficiency of coal mining operations. By processing the coal on-site, transportation costs are reduced, and the overall productivity of the mine is increased.
Conclusion
CHPP, or Coal Handling and Preparation Plant, is a facility that processes coal to improve its quality and prepare it for transportation to the market. It plays a crucial role in the coal mining industry by removing impurities and ensuring a consistent supply of high-quality coal.
