The objective of cone crusher optimization is the maximal output of the cone crusher, as shown in Eq. (7). The product quality including particle size and particle shape are taken as constraints of optimization, as shown in Eq. (8). P CSS is the product weight percentage passing CSS, and it is a key parameter for estimating product size.
dynamic impact. When the material is crushed in an impact crusher, the freely falling material first breaks due to dynamic impact by a moving hammer and then the force of impact accelerates movement of the reduced particles toward breaker blocks and/or other hammers for further size reduction. Dynamic impact has specific advantages for the ...

An impact crusher can be further classified as Horizontal impact crusher (HSI) and vertical shaft impact crusher (VSI) based on the type of arrangement of the impact rotor and shaft. Horizontal shaft impact crusher These break rock by impacting the rock with hammers/blow bars that are fixed upon the outer edge of a spinning rotor.
Barmac® vertical shaft impact (VSI) crushers were the first vertical shaft impactors in the world. The original Barmac® was developed in New Zealand over 40 years ago after which the VSI crushers have spread to thousands of crushing sites around the globe. Barmac® crushers have evolved immensely over the years, but their trademark is still ...
the parameters of the crusher. A significant effect of the angle of application of force on the change of stresses is observed in the range of 0.3–0.5 (Fig. 3).
The crusher geometry and the set-up of the simulation were done using the PFC3D (version 2.1, Itasca Group, Inc., Minneapolis, MN, USA) [18] which has an internal program-ming language called Fish. The model parameters are presented in Table1. The impact crusher design and the rendering of its simulated version are shown in Figure1, with di-
