Coal gangue sand making process
Coal gangue is a typical coal associated waste rock, low carbon content, hardness, a large amount of accumulation will not only occupy land resources, aggravate the economic burden of coal plant, but also cause serious pollution to the ecological environment, so it is urgent to realize its comprehensive utilization. In recent years, with the continuous development of industrial technology, through the gangue sand processing, it can be used for power generation, brick making, soil improvement, but also for the production of cement or chemical supplies.
Coal gangue: finished particle size of about 30 mesh. What is the process flow of coal gangue sand making? What equipment is needed?
1. Coarse crushing equipment: Jaw crusher is coarse crushing of coal gangue “weapon”, its simple structure, small size, flexible use, large crushing ratio, high crushing efficiency, and the quality is more guaranteed, can better complete the coarse crushing of coal gangue operations.
2. Coal gangue crushing equipment: impact crusher is a very good crushing equipment, impact can achieve the effect of material crushing, good stone shaping effect, can provide better quality raw materials for sand making.
3.Gangue sand making equipment: sand making machine is the key equipment of gangue sand making process, its high efficiency and high yield, low noise, no pollution, small size, low investment cost, and made of sand quality, strong, beautiful particle size, grading and rationalization, with better market application prospects.
4. Gangue screening equipment: circular vibrating screen has always been the gangue screening equipment, which has a multi-layer screen setup, the material can be screened into a variety of different specifications, better results, higher efficiency.
5. Coal gangue feeding equipment: vibrating feeder running feed evenly, not blocked, low noise, no pollution, can maintain normal operation for a long time, very strong adaptability to the environment.
6. gangue conveying equipment: belt conveyor through the whole gangue sand making process, mainly bear the material conveying operation, its flexible and lightweight, easy to install, low operating costs, the use of the effect is very good.
Introduction to the gangue sand making process:
Coal gangue sand making process is relatively simple, roughly divided into coarse crushing, crushing, sand three stages, large gangue raw materials from the vibrating feeder uniformly fed into the jaw crusher for initial coarse crushing operations; after a reasonable screening by the vibrating screen, only to meet the requirements of a certain particle size of the qualified materials can be entered into the cone crusher/impact crusher crushing processing, unqualified materials will be sent back to continue coarse crushing; next, the qualified materials will be crushed in the belt conveyor, and then the crushed materials will be sent to the crusher for further crushing. Next, the qualified materials will be sent to VSI sand making machine for fine crushing and shaping under the action of belt conveyor to get the finished gangue sand; it can be packaged and sold to the market.
