Although coal gangue is the solid waste discharged in the process of coal mining and coal washing, but after crushing treatment can be used in some fields, there is a certain commercial value, specific coal gangue after crushing what use? Crushing coal gangue process and equipment configuration and how? Here to answer your questions.
What is the use of coal gangue after crushing?
1 for brick making
After the gangue is crushed, after a series of brick making process such as forming, drying and roasting, it can be made into gangue bricks, whose strength is twice as strong as ordinary clay bricks, and the quality is also very good.
2 used to make cement
After crushed gangue is treated by carbon pre-selection and activation, it can produce active alumina and silica, which can be used as active mixing material for cement, with the advantage of saving clay and iron ore resources.
3 for calcined kaolin
The content of kaolin in coal gangue is up to 70%, so coal gangue is usually called coal kaolinite. After crushing and purifying, it can be used as high quality raw material for manufacturing calcined kaolin.
4 As road base material
After the coal gangue is crushed into sand, its particle size distribution, solidity, density and other aspects meet the requirements of use, so it can be used for the preparation of concrete, mortar, road bedding and other fields.
Coal gangue crushing production line process flow and equipment configuration
The coal gangue crushing and sand making production line equipment designed by hotonmach for a stone plant in Jiaozuo, Henan Province is mainly composed of jaw crusher, impact crusher, impact sand making machine, bucket sand washing machine, vibrating feeder, circular vibrating screen, tape conveyor, etc. The process is as follows.
1、Bulk gangue is evenly fed by vibrating feeder and conveyed to jaw crusher for coarse crushing through conveyor, and the coarse crushed gangue is screened by vibrating screen.
2, after screening the material needs to be crushed twice, the material will be transported to the impact crusher for crushing, the use of circular vibrating screen for screening, the larger particles of coal gangue returned to the impact crusher for crushing again.
3, the secondary crushed gangue sent to the sand making machine for further crushing and shaping, so that its granularity is more uniform and beautiful; then the material will be sent to the sand washing machine for cleaning, should be clean finished gangue particles for packaging and storage.
Advantage: long service life, large output, high efficiency, good granularity of the finished product, sand making both shaping.
How much is a set of coal gangue crushing production line equipment?
Coal gangue crushing production line has a variety of different configuration options, and different output requirements, equipment model configuration is not the same. All of these will cause different capital investment, a set of coal gangue crusher specific how much you can call or online consultation, message, HOTONMACH will send professional staff for your customized design coal gangue production line configuration program and quotation.
