Hammermill Crushers are known to generate material finer than 3/16" (4mm), which in some applications may be undesirable. However, if there is a market for finer material, or if it is acceptable within the desired product size, Hammermills can achieve reduction ratios that may otherwise require multiple crushers.
They provide a reduction ratio of 3:1 to 6:1. Jaw Crushers feature a moving piece of steel (called the pitman) and a stationary piece of steel that form a V-shaped chamber. Material that enters the chamber is crushed to size between the moving piece of steel and the stationary piece of steel. Most of the crushing action occurs in the bottom ...

The secondary crusher has a size reduction ratio ranging from 3:1 to 5:1. The secondary crusher can be a cone crusher, impact crusher, or gyratory crusher, depending on the hardness, abrasiveness, and size of the materials. The cone crusher is the most common type of secondary crusher used in mining and quarrying operations.
In a crusher's design, attention to the reduction ratio is critical. This ratio reflects the degree to which the material is reduced in size from the feed to the product. A high reduction ratio indicates a powerful crushing capacity, such as reducing 150-centimeter-wide iron ore to a 30-centimeter-wide material.
The reduction ratio of a jaw crusher is a critical parameter that determines the efficiency of the crushing process. It is defined as the ratio of the size of the feed material to the size of the product. In other words, it is the degree of reduction or size reduction achieved in the crushing process. The reduction ratio is an essential factor ...
R r = Crusher Reduction Ratio G = Gape Size S = Set Size. Let's solve an example; Find the crusher reduction ratio when the gape size is 20 and the set size is 10. This implies that; G = Gape Size …
The crusher feed rate can increase to maintain the same crushing rate. Taggart expressed the relationship between crusher capacity and reduction ratio in terms of a reduction ton or tonne, Q R defined as (4.22) Q R = Q T ⋅ R 80 where Q T is the capacity in terms of actual tonnage crushed per hour. The quantity of feed actually …

Selecting the right crusher for your project can be a complex decision, given the range of available options. Each type of crusher has its own unique benefits and applications.
A good rule of thumb for single-stage crushers is that a Single Roll Crusher provides up to a 6:1 ratio of reduction and a Double Roll Crusher provides up to a 4:1 ratio of reduction. In the event that the application requirement exceeds the guidelines discussed herein, dictating more than one crushing stage, then a determination will have …
Balance Throughput & Reduction Ratio. Sometimes production capacity needs to be given priority over reduction ratios and vice versa. You can optimize for one over the other by adjusting certain cone crusher parameters. For maximizing capacity, use a flatter crushing chamber, larger head diameter, faster eccentric speeds, and shorter …
