The particle size of the raw material for coal gangue brick making is the basis for quality assurance. The crushing particle size should be less than 1.5mm, of which particles below 0.5mm account for more than 65%. The processing of coal gangue is divided into three stages: coarse crushing of jaw crusher, medium and fine crushing of impact crusher or cone crusher, and sand shaping of sand making machine.According to its characteristics, the crushers generally used can be divided into the following types. You can choose the appropriate products according to your own needs.：
The first stage: coarse crushing
If your coal gangue raw material has a large particle size, you can choose the configuration of jaw crusher + impact crusher/cone crusher. This scheme has wide applicability. Large pieces of coal gangue are evenly fed by the vibrating feeder through the silo and transported to the jaw crusher for coarse crushing. After the coarse crushing, the coal gangue is sieved by a vibrating screen and transported by a belt conveyor to the impact crusher or cone crusher for medium and fine crushing. The bricks prepared in this way have better properties and high market prices. It is suitable for small and medium-sized coal gangue brick factories that pay attention to product quality.It is characterized by high crushing force, high production capacity, simple maintenance and so on.
The second stage: medium and fine crushing
After the coal gangue transported to the counterattack break/cone break is finely crushed, a circular vibrating screen is used for screening, and the larger particles of coal gangue are returned to the counterattack break/cone break and broken again.The characteristics of this equipment are: economical and applicable, easy to adjust the discharge, etc.
The third stage: sand making
The sand making machine is the core equipment to complete the task of coal gangue sand making. It can modify the finished coal gangue to be more rounded, with uniform particle size and fineness.Its maximum feed particle size is between 55mm, the output range is 12-650t/h, the crushing efficiency is high, the finished product has a good particle size, and the equipment is mature and durable. If your raw material has a small particle size and a large output demand, it is very suitable to choose it.The broken coal gangue is fed into the sand making machine for further crushing and shaping. If clean coal gangue is needed, it can be fed into the sand washing machine for cleaning.
The fourth stage: packaging
The finished coal gangue after drying is packaged and stored.
