By changing the mixing rate of plant fibers and coal gangue, the mix design of plant fiber recycled concrete and experiment. According to the compressive strength values of 7d, 14d and 28d concrete, the optimal mix ratio is selected.
The coal is conveyed from the bin at 1,200 tonnes per hour on an apron feeder through a primary crusher where it is sized to less than 200mm. The coal is then conveyed to a screen where it is sized to either less than or more than 50mm. The more than 50mm product stream goes to a secondary crusher to be crushed to under 50mm.
