The crushing process of concrete is nearly the same as stone crushing. Firstly, we choose the usable materials and transmit them with the vibrating feeder. Then vibrating feeder pours them into primary mobile concrete crusher. Then products of primary concrete crusher get crushed by secondary mobile concrete crusher.
