Crusher and grinding mill make coal utilization more efficiently
The exploration and utilization of coal has played an important role in economy development, but causes great damage on environment. Coal gangue and CBM development are the main wastes. The coal gangue is the solid waste produced during the excavation, mining and washing process of coal. It consists of carbon, shale and sandy shale, and has a low calorific value. The carbon content is 20% ~ 30%, some contain humic acid. They exist in large quantity in countries of rich coal resources, which not only piles up the place and contaminate the environment but also causes fire due to auto-ignition. As energy is increasingly short, people gradually realize these wastes are employable. If the coal gangue can be differentiated and crushed by breakage and grinding equipment, such as jaw crusher, impact crusher, grinding machine, they can be utilized to achieve economic benefit in roughly five aspects:
1. Filling the colliery. The coal gangue can be used as filling materials in underground coal cavity directly or after processing.
2. Filling the ground such as road building.
3. Generating power. Coal gangue containing rich carbon and high calorific value is used for fluidized bed and circulating fluidized-bed power generation.
4. Building materials. The coal gangue is made into gangue brick, cement and lightweight aggregate to act as building materials.
5. Extracted sulfur ore or other chemical products from coal gangue and other
All these utilizations need crushing by jaw crusher, impact crusher, Raymond milling machine, High pressure suspension grinding mill, micro-powder mill.

Pocahontas Exhibition Coal Mine $70.1 High Quality Content by WIKIPEDIA articles Pocahontas Exhibition Coal Mine, also known as Pocahontas Mine No. 1, or Baby Mine, is an inactive coal mine in the Pocahontas coalfield. The mine was the first in the subbituminous coal of the Pocahontas coalfield, opening in 1882. In 1938 it became the first exhibition coal mine in the United States. Uniquely, it was possible to drive ones automobile through the mine, entering through the fan opening and exiting through the original entry. The practice continued until 1970, when it was discontinued due to damage to the roof of the mine from car exhaust. The site is also notable for its history of coke production on site for transportation by rail to steel mills. Pocahontas coal was especially suitable for coking, and played a significant role in the industrial development of the United States. Coke and coal were shipped by rail to Norfolk, Virginia for transshipment to eastern US ports and overseas. Coking on the site was eventually discontinued, and the mine spoil pile now covers all by three beehive coking ovens. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.
