Cone Crushers. A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point.

Even though the original cone crusher patents were accepted almost 100 years ago (in the mid 1920''s by E B Symons), the cone crusher concept continues to be an outstanding success. Cone crushers are in common use wherever crushing is required. Cone crushing for aggregate production far exceeds all other applications including mineral processing.

In Figure 5, the operation principle of the cone crusher is that the rotation of the eccentric drives the mantle to realize precession, and then particles are squeezed and crushed in the crushing chamber. The trajectory model of the mantle is the basic condition to determine the actual activity space and singularity of the 6-DOF robotic crusher.

Cone Crusher Cavity Types. You should have a well-graded feed going into the crushing chamber. A well-graded feed is generally considered as: 90-100% passing the closed-side feed opening. Some people look at 80% of the open side as well and select the smaller of the two. 40-60% passing the midpoint. 0-10% passing the closed-side setting.

It is known and also predicted by the model that the cone crusher''s total throughput depends on the Eccentric Speed, and exhibits a quasi-concave response with respect to this variable.On-line optimization of the throughput is suggested to be based on the concept of Extremum Seeking Control (ESC).Two dierent methods of ESC were applied.
