The electric machine built-in roller crusher is an explosion-proof electric machine used in the crushing roller. Results: Both of these crushers can be used in the selective crushing technology of coal gangue in a coal mine and can meet the requirements of crushing different material sizes and generally avoid the centre of the roller crusher.
Traditional Coal Gangue Separation Process and Equipment. Water washing and dry coal preparation are the main parts of coal preparation. Spiral separation, jigging, heavy medium separation, and other processes are water washing processes, which have the advantages of mature technology, high separation accuracy, and large processing …
The compaction and re-crushing characteristics of quarry filling material are important factors which affect its filling effect and quality [1,2].As the gangue filling material is widely-sourced, economical, and inexpensive, mine-filling accounts for most of its use, and the gangue material as a filling body can account for a large amount of gangue, …
The mix proportion of multi-source coal-based solid waste (CSW) for underground backfilling affects transportation and support performance of backfill materials, and even the backfilling cost. In ...
The coal gangue vertical compound crusher can achieve more crushing and less grinding and is an ideal fine crushing equipment for energy saving and consumption reduction.
A coal crusher is a machine that processes coal into smaller pieces. It typically consists of a series of crushers such as jaw crushers, cone crushers, impact …
