The seal,(PDF) Coal Preparation | Aimal Khan - Academia.edu,The type of machine used depends on the size of the material being screened, the size separation demands, and the desired capacity.Vibrating screens can be operated either dry or wet, although since most coal preparation processes are water-based, coal screening on vibrating screens is generally done wet. These perform very well at the coarser sizes, but these are prone to blinding and damage,

Coal – Types, Uses and Formation

Coal is extracted by different kinds of mining activities on the Earth’s surface. The most common ones are surface mining and underground mining. Surface mining is done when coal is less than 200 feet below ground level. In this process, mineworkers have to remove all kinds of rocks and soil-forming the top layer. It is cheaper than underground coal mining. There are three types of surface,,,,,,
