Roll Crushers
Single Roll Crushers. Single Roll Crushers are typically used as primary crushers that provide a crushing ratio of up to 6:1. They crush materials such as ROM coal, mine refuse, shale, slate, gypsum, bauxite, salt, soft shale, etc., while producing minimal fines.Designed with intermeshing roll teeth and a curved crushing plate, they are extremely effective in reducing slabby feeds.

What Is The Ratio?
This led to the word "ratio" itself becoming an insult and a meme. For example, the popular L + Ratio meme became a sort of copypasta that could be found under disagreeable tweets, with people noting that the above tweet would suffer a terrible ratio amidst other insults. Additionally, some people will attempt to "ratio" a tweet themselves.

crusher crushing ratio and capacity
The crushing ratio of a jaw crusher results from the maximum achievable final fineness in relation to the maximum feed size. For Retsch jaw crushers, this lies between 26 and 220. A high value reflects the capacity of a jaw crusher to accept large sample pieces and provide powerful crushing performance, resulting in high final fineness.

Size reduction (GIKI) | PPT
4. Energy for size reduction • The energy dE required to effect a small change dL in the size of unit mass of material is a simple power function of the size. • Rittinger's law: – putting p = −2, then integration gives: – Writing C = KRfc, where fc is the crushing strength of the material, then Rittinger's law, first postulated in 1867, is obtained as: – Since the surface of ...
Crusher Close Side Settings
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 is …
