What is Reduction Ratio of Crusher

It is mentioned by many pro users that the percentage of the voids or an empty place as relevant information in the chamber which is called as the crushing chamber gets decreases and along with that, there is an increase in the production of the with the help of the attrition in a simultaneous nature.

Here in has mentioned much such relevant information related to the crusher. Even if the setting of the discharge has no change in it, there is a decrease and increase in the voids and production respectively and in short, both are indirectly related to each other. Both the above statements are all correct, but the product is affected to a certain degree and that is dependent on the ratio of the volume of reduction in the crusher.

Calculated methods of the reduction ratio:

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 of the particle to be a maximum particle, the ratio calculation is performed. The sieve aperture width is the maximum size diameter which is taken in Britain and the United States which is present in the 80% materials, China and the former Soviet Union to the material of about 95% present in total quantity.

Step2: The second method of calculating the reduction ratio of the crusher is with the help of the width of the crusher feeding port and along with that the width of the ratio of the discharge opening. This method is considered as the easier one when compared with the former one.

Step3: The second method of calculating the reduction ratio of the crusher is with the help of the size of the particle which is average particle size and through that calculation of the average diameter is performed and the average diameter of broken is calculated before the material ratio so that there is no mathematical complexity present.

All the fragmentation methods that are mentioned above can reflect more of the real degree of fragmentation, and this is the reason why theoretical research often is used by experts. Basically, every crusher machine which is available in the market is not the same and it is not practically possible, so to make it easy for you, given below are the reduction ratio in the size of the several common crushers:

● The reduction ratio in the size of the impact crusher is from 20 to 1.
● The reduction ratio in the size of the impact crusher of the type of the vertical shaft is from 4-8 to 1.
● The reduction ratio in the size of the vertical roller mill is from 2-2.5 to 1.
● The reduction ratio in the size of the hammer crusher is from 20 to 1.
