Workers in coal-preparation plants, where vibrating screens are significant noise sources, are often exposed to sound levels exceeding 90 dBA. The National Institute for Occupational Safety and Health, a major coal company and a vibrating-screen manufacturer conducted a cooperative study of vibrating-screen
and a vibrating screen manufacturer at a coal preparation plant. The consortium selected a coal preparation plant for the study based on its proximity to all of the involved researchers. In the selected plant, preliminary measurements were made in the area surrounding a group of eight horizontal vibrating screens used to process clean coal.
May 16, 2012 Coal Screening Plant Features 1. It uses eccentric block to produce strong exciting force. 2. Crossbeam and the main body of the screen are connected with high strength screw bolts. So they have the features of simple structure and easy maintenance. 3. It adopts tire coupling with capability of flexible connection and stable operation. 4.
In coal preparation, screening machines serve two purposes sizing and media recovery. Oftentimes, the initial screening is performed by a scalping screen located outside the plant. This prevents the screens inside the plant from becoming overloaded. The deslime screens make the next cut and most prep plants size to minus 1 mm.

As a result of the clean coal discussion, coal washing plants are in vogue. The term coal handling and processing plant CPP or CHPP is today often used to describe a coal washing plant Fig. 12. Since the processes in such a plant are largely comparable, more and more standardized plants MCPP, M Modular are being built.
A horizontal vibrating screen see Figure 1 is a large machine used to process clean coal that has been separated from refuse materials using a water-magnetite mixture. This magnetite is recovered because the magnetite lowers the heating value of coal and it can be re-used in the processing plant.
Now, Vibrating screens are widely used in industrial sectors such as mining, metallurgy, coal, hydropower, transportation, and chemical sectors to perform a variety of processes. such as screening, grading, washing, decontamination, and dewatering of materials. Mineral processing is an intermediate link in mining and smelting.
