Size Reduction: Significance, Mechanisms, Factors, and …
Ratio of feed size to product size: To achieve a fine powder in a mill, it is necessary to use a relatively small feed size. Because of this, the size reduction process is carried out in several stages using different equipment, such as preliminary crushing, followed by coarse powder, and then fine grinding.

Despite occasional claims to the contrary it is unwise to effect size reduction much below 1″ by a cone crusher. The cone-type gyratory, of which the "' is perhaps best known, is pre-eminent as a secondary crusher and is capable of effecting a size reduction ratio of the order of 6-8:1.
What affects cone crusher performance?
Any fluctuation in pressure means that the optimal force will not be delivered consistently so, of course, crusher performance declines. These are the two main causes of sub-optimal crushing performance, but losses in the reduction ratio can also be caused by selecting the wrong mantle or by having a poor chamber profile or design.

Types of Rock Crushers | Quarry Crushing Equipment | Kemper
Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types. 2. Secondary Crushing. In secondary crushing, reduction ratios become an essential consideration.
How Do I Know Which Primary Crusher Is Best For My …
Generally, a Quad Roll Crusher is recommended for a medium size feed material, while the Triple Roll Crusher, with its single roll top stage, is effective for handling larger size feeds. These machines do the work normally assigned to two separate crushers. Typical feed sizes range from 18" – 72" with final product size of ½" – 3".
Factors to Consider When Selecting the Proper …
There are numerous factors to be considered, such as: Material to be crushed. Feed size. Product size. Ratio of reduction. Capacity. Compressive strength. Moisture content. Amount and type …
What is Reduction Ratio of Crusher – The Riverenza
Calculated methods of the reduction ratio: The reduction ratio of the crusher size is simply calculated as the ratio of the particle size of the raw material and particle size of the crushing. Step1: When the maximum size of the particle is being considered and along with that the broken material after the product and before the size …

Cone Crusher Sizing & Selection To Maximize Production
The greater the closed-side setting range, the more flexibility you have to adjust output. Consider whether you need a unit tuned for high volume or optimized for increased reduction ratios. High-capacity crushers have a lower reduction than slower speed but higher compression crushers. Know The Maximum Feed Size For Crushing
Exploring Jaw Crusher Efficiency | Kemper Equipment
Jaw Crusher Reduction Ratio. Either an 8-to-1 or 6-to-1 ratio should be the target reduction ratio for maximum jaw crusher efficiency. This setting typically provides an ideal P80 factor—when 80% of crushed material produced by primary crushing will pass screening after processing. A smaller closed-side setting will produce more fines.
Jaw Crusher
Inversely, at a given reduction ratio, effective streamlining could increase the capacity by 30%. – The typical reduction ratio is bound to be between 6 and 8 and is similar that of jaw equipment. – Applying the crushing force by rolling the nut breaks flats and gives a product that is more "cubic" than the jaw crusher. –
Crusher Reduction Ratio
As an example, suppose that it is required to make a reduction of 7:1 in two stages of crushers, one a standard gyratory and the other a fine-reduction crusher.
