Required reduction ratio; A jaw crusher size is obtained by looking at its feed opening (gape) and length. As an example, a monster 7959 of 79″ x 59″ (2m x 1.5m) will have its fixed jaws 79″ apart where the feed enters on a 59″ wide set of liner plates. The factors list below will enhance crusher capacity and performance: 1.
A jaw crusher is an indispensable tool in the mining and construction industries, known for its power to fragment hard materials such as rock and minerals. ... It powers up those who run the show to make smart calls – like getting that CSS just right or figuring out the reduction ratios to get the crusher working just how they need it to ...
Ideally, the reduction ratio of a jaw crusher should be 6:1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input …
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 = 20 S = Set Size = 10. R r = G / S So, R r = 20 / 10 R r = 2. Therefore, the crusher reduction ratio is 2. Calculating the Gape Size when the ...
be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1. The primary operating variable available on a crusher is the set and on jaw and gyratory the open-
Taggart expressed the relationship between crusher capacity and reduction ratio in terms of a reduction ton or tonne, Q R defined as (4.22) ... The ore had to be crushed in a C-63 type jaw crusher 630 × 440. At a reduction ratio of 4, 18% of the ore was below the maximum size required. Determine: 1.
Experiment # 02: Reduction Ratio of Jaw Crusher 2.1. Objectives: 1. To study the various parts of Laboratory Jaw crusher with special emphasis on their functions to perform a crushing test on a given sample 2. To analyze the product by sieve analysis 3. To calculate reduction ratio 2.2. Apparatus/Materials: • Laboratory Jaw Crusher • Vernier Caliper • Rock …
A jaw angle of 15-20° results in a reduction ratio of 4 to 6. Various jaw crushers with different design features have been developed; of them generally two types remained master of the field, namely the double-tog gle jaw crusher (also called Blake-crusher), which is shown in Fig. 3.9. and the single-toggle jaw crusher shown in Fig. 3.10. [35].
p – Size reduction ratio • Coarse grinding has RRs below 8:1 • Fine grinding can exceed 100:1 ... Jaw crusher • Feed is admitted between two jaws, which are open at the top like V • One of the jaws is fixed and vertical, while the other is the swinging jaw
One jaw is stationary while the other is moveable. The gap between the jaws becomes narrower farther down into the crusher. As the moveable jaw pushes against the stone in the chamber, the stone is fractured and reduced, moving down the chamber to the opening at the bottom. The reduction ratio for a jaw crusher is typically 6-to-1, although it ...

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.
