Vertical shaft impact crushers produce a small reduction ratio and arc often used for crushing tines. In hammer mills the impact of a fast-moving hammer on a slow-moving rock causes shattering. It can also be caused by the collision of a rock traveling at high velocity with another rock or a breaker plate. ... 's CV range of VSI ...
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.

The reduction ratio of a jaw crusher is a critical parameter that determines the efficiency of the crushing process. It is defined as the ratio of the size of the feed material to the size of the product. In other …
VSI and GS series crushers are characterized by a unique closed-rotor design providing a higher reduction ratio with lower wear cost. The GS series crusher's bearing seat uses a thin oil lubrication system. Its highest rotor speed is clocked at 82m/s, greatly improving the capacity of the equipment and processing efficiency.
Crusher Reduction Ratio What is the impact of the Crusher Reduction Ratio on crusher performanceMar 04, 2017 All crushers have a limited reduction ratio m ean
The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. It …

Crusher adjustment (CSS) The closed side setting (CSS) defines the reduction ratio in cone crushers and has a significant effect on product gradation, capacity, and power draw. The closed side setting is measured from the bottom of the mantle to the bottom of the bowl liner at their closest point during the gyrating cycle.
The equation for Rittinger's Law can be written as: E = K R f c (1/L 2 – 1/L 1) Where: E=Energy, K R =Rittinger's Constant, f c =crushing strength of the material, L 1 =initial length, and L 2 =reduced length. Kick's Law states that the energy is proportional to the size reduction ratio. The equation for Kick's Law can be written as:

While various crusher sizes have similar CSS range spans, some crushers operate in a bit tighter CSS range than others. The key is looking at the desired reduction ratio, or how far you wish to break material down in one pass.
