For REMco crushers, the reduction ratio is calculated as the relationship of the maximum feed size to the desired product size. For example, with a medium limestone feed not exceeding 6" and a product requirement of -1/4", the reduction is 6.0 ÷ 0.250 = 24:1. With harder rocks, the max reduction ratio may be lower. When

Usually, these crushers deliver a 4:1, 5:1, or 6:1 reduction ratio. As you reduce the closed side setting to produce smaller material, you also reduce the capacity of the machine. Cone crushers are well adapted to handle many different types of material, but they're only able to accept material up to a certain size.

Cone crushers are very suitable for size reduction and shaping in the downstream of a crushing circuit. They reduce the material in a crushing cavity by continuous compression between a fixed element (bowl liner) and a moving element (mantle). Cone crushers are equipped with a hydraulic setting adjustment system, which allows adjusting the ...

VSI crushers generally have lower operating and maintenance costs than HSI crushers. VSI crushers have fewer moving parts, as they do not require blow bars or hammers to be replaced frequently as with HSI crushers. ... For secondary and tertiary crushing applications, VSI crushers have a higher reduction ratio, meaning they can …

Secondary crushing is the second stage of crushing that takes place after the primary crushing. The secondary crusher is the equipment that reduces the size of the materials further, after they have been reduced by the primary crusher. The secondary crusher has a size reduction ratio ranging from 3:1 to 5:1. The secondary crusher can …

Fig 1 Methods for size reduction of materials The reduction of size of the material when it pass through a crusher is expressed as reduction ratio. The reduction ratio is the ratio of the crusher feed size to product size. The sizes are usually defined as the 80 % passing size of the cumulative size distribution. Types of crushers
