The second type became quite popular in the past decade and is known as the Barmac crusher. 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.
