Feb 25, 2015 roll crusher • the reduction ratio and efficiency of roll crusher is very low. • the main advantage associated with roll crushers is small proportion of fines produced and more uniform size of product crushed, than the other crushers. • low capacity • low reduction ratio = f/p • sensitive to top size 2/25/2015 6:58:05 am 38 39.Crushers are major size reduction equipment used in mechanical , metallurgical and allied industries.they are available in various sizes and capacities ranging from 0.2 ton/hr to 50 ton/hr.they are classified based on different factors like product size and mechanism used.based on the mechanism used crushers are of three types namely cone.Mar 21, 2019 the crushing process is often characterized by the ratio of the size of the initial material to the size of the product . for cone crushers, this ratio is between 3 : 1 and 10 : 1 for primary crushing; between 6 : 1 and 8 : 1 for secondary crushing; and up to 10 : 1 for tertiary crushing [ 15 ].
Crusher run is crushed natural limestone, unlike crushed asphalt that is an oil product. crusher run consists of 3/4 particles plus a specific blend of stone dust. the stone dust fills the voids between the rocks to ensure that they are interlocked tightly and will not move with the time.

If a single-stage reduction is required, then depending on the feed-to-product-size ratio of reduction, either a single or double roll crusher can be selected. regardless of the crusher type selected, roll crushers allow for the material to fracture along naturally occurring cleavage lines, which helps with minimizing fines generation.
To make sure that your crusher is delivering the desired product, and maximizing its efficiency and productivity, there are a few potential issues that you should be alert to. at sandvik we have researched the factors that – if not properly addressed – can cause cone crushers jaw crusher.
