Concrete recycling - Wikipedia

Large road-portable plants can crush concrete and asphalt rubble at 600 tons per hour. These systems normally include a side discharge conveyor, a screening plant, and a return conveyor from the screen back to the crusher for re-crushing large chunks. Compact, self-contained crushers can crush up to 150 tons per hour and fit into tighter areas.

Reinforced concrete - Wikipedia

Reinforced concrete (RC), also called reinforced cement concrete (RCC), is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars and is usually embedded passively in the concrete before the concrete

If larger rebar is in the concrete and cannot be removed from the concrete, the crusher should be opened up to allow larger material to pass through. This helps remove the steel from the crushed material on the discharge belt, according to Griess. "Jaw crushers work best for large amounts of steel in the concrete," he adds.

Tips on Choosing a Concrete Crusher for Demolition

While jaw crushers use pressure to break up concrete, impact crushers rely on impact (as their name implies). Some impact crushers throw the rock against hard surfaces with such velocity that the rocks naturally break along internal fissures. Other impact crushers use hammers on the outer edge of a spinning rotor to break up materials.
