the difference between a conventional impactor and a vsi of the barmac type is that the latter offers lower operating costs, but its reduction ratio is lower also. In a barmac vsi, the material undergoes an intense rock-on-rock crushing process. In the other crushers, most of the reduction is done by the impact of stone against metal.

May 08 2020 · sep 02, 2019 they are compression crushers that generally provide reduction ratios of 6-to-1 to 4-to-1. cone crushers are used in secondary, tertiary and quaternary stages. with proper choke-feed, cone-speed and reduction-ratio settings, cone crushers will efficiently produce material that is high quality and cubical in nature.
may 13, 2019 efficiency can be defined by the ratio of a machines work to the energy supplied to the machine. To apply what this means to your crusher, operations produce the exact sizes in the reduction process that their market demands. In the past, quarries produced a range of single-size aggregate products up to 40 mm in size.
