Size Reduction and Energy Requirement
In closed circuit, the product from the stage of size reduction is separated into relatively fine and coarse fractions. The coarser fraction is then collected and re-crushed in the same unit as seen in Figure 3.2.In doing so, the load on the equipment for size reduction is increased and a circulating load is established, but the total number of units required for …

Analysis and optimization of cone crusher performance
Solving practical problems in cone crusher design, the quantity of rock material falling out of the crushing chamber during one eccentric rotation of the cone was analyzed. A simple and practical model for predicting cone crusher output is proposed. Based on previous research a model able to directly calculate the mass percentage of flakiness in the product has …

In the rock crushing test results of the specimens, we calculate the average working energy and the work efficiency. In order to maximize the work efficiency, the rock crusher tool is important to reduce the rotational speed of tool and increase the contact surface of the cutter bits and the rock having a compressive strength of 20 MPa or less.

Collision Energy Analysis within the Vertical Shaft Impact Crusher
The rotor speed was maintained at 1000 and 1600 rpm, while the feed rate was set at 108 t/h. Crushing tests were conducted, and the average power of the crusher operating under two distinct conditions was determined; the average power was then used to calculate the specific energy consumed by the crusher in the experiment.

A fundamental model of an industrial-scale jaw crusher
The kinematics of the single-toggle crusher has been modelled by Oduori et al. (2015). An energy efficiency study was performed by Legendre and Zevenhoven (2014). In their study, energy was estimated with the Bond work index, and an on-line optimization algorithm was used to increase the efficiency of a laboratory crusher.
