Features

Ring hammer coal crusher is a series coal crushing machinery, which is designed to use in the coal handling g systems of the steam electric power plants. It can efficiently and economically crush raw coal to the grain sizes specified for the boilers. By comparison with other types of coal crushers, it has advantages of less noise, less dust, low power ratio, etc.

Applications

The coal crusher is suitable for crashing bituminous coal, smokeless coal, lignitous coal and freezing coal. The crushed material shall usually have compression strength of not more than 12MPa (120Kg/cm). Also the crusher can be used in the coal, construction material, chemical industry, light industry, textile and other departments for crushing brittle medium-hard material such as coke, slag lime stone, etc.
