The coal is therefore cleaned by a special method, known as the Chance process, in which a suspension of sand in water is used for separating the dirt from the clean coal. By this means it is possible to obtain coal which contains only 2½ per cent of ash. The clean coal is stored in bunkers near the plant, and there is always sufficient reserve for two days’ operation.

In a coal processing plant, the number of different screens may be 50 or more. Many of these are dewatering screens. The classical screening machines include eccentric vibrating screens, which are used either as a pre-separator or for the screening of coarse and difficult-to-screen coals. Such screening machines operate with a load-independent, constant oscillating circuit to counteract

Coal fired power plants follow the Rankine cycle in order to complete this process. Since they require plenty of water to be circulated in this cycle, coal power plants need to be located near a body of water. The process of coal fired plants can be seen below in Figure 3. Figure 3. The process of a coal fired power plant to convert coal into

Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore concentrate. A simplified flow diagram of these processing steps is shown in Figure 11.23-1.

The coal mill grinding system is an important part of the dry process cement manufacturing. In cement plants, we usually adopt the air swept coal mill system or vertical mill system as the pulverized coal preparation system, which is arranged at the cement kiln head or kiln tail to provide fuel for clinker calcination.
