Investigation of recycled concrete made with limestone aggregate for a base course in flexible pavement depending on the crusher settings, and generally a lower density than virgin aggregates. One of the most distinctive fea- impact, and grinding occurring in a rotating steel drum containing a.Impact crushers. An impact crusher uses mass and velocity to break down feed material. First, the feed material is reduced as it enters the crusher and makes contact with the rotating blow bars or hammers in the rotor. Secondary breakage then occurs as the material is accelerated into the stationary aprons or breaker plates.
