A review of modeling and control strategies for cone crushers in
Fig. 1 presents a simplified diagram of a cone crusher. Cone crushers consist of a circular outer concave enclosing a cone-shaped mantle that moves eccentrically, see Fig. 1. As the distance between the mantle and concave inner wall increases, rock particles fall; when the distance de-creases, the particles are compressed and crushed.The present study investigates the effects of rock crushing circuits on aggregate quality. For this purpose, a crushing-screening plant located in Vize (Kırklareli, Turkey) was considered.(PDF) INVESTIGATION OF ROCK AGGREGATE QUALITY
