Crusher Reduction Ratio

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

Maximum feed size. Reduction ratio must be limited to 3 (-4). Recommended max feed size is 50 mm. Correct feed distribution. Feed distribution should be non segregated and evenly distributed around crushing cavity. Setting closer to required product; Correct choke point. This means the right selection of cavities for feed in question. Crusher,

Reduction ratio Main use; Compound crusher: Medium hard to very hard: Abrasive: Dry or wet, not sticky: 3/1 to 5/1: Mine, building materials: Cone crushers: Medium hard to very hard: Abrasive: Dry or wet, not sticky: 3/1 to 5/1: Quarried materials, sand & gravel: Crusher buckets: Soft to very hard: No limit: Dry or wet and sticky: 3/1 to 5/1

Using the F80 rule with the 32 x 54 Jaw Crusher, the 32” gape opening equals a 26” top sized feed, and with the 6:1 ratio of reduction, the discharge setting would be around 4”. Since the crushing of the material is not performed in one stroke of the eccentric shaft, massive weighted flywheels are attached to the eccentric shaft and,

May 06, 2021· 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.

Dec 26, 2015· Primary crushers are designed so that the maximum size that can be presented to 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.

lifetime of the crusher. These designs protect the most expensive main components from wear and shorten maintenance time. And a shorter maintenance time means higher uptime. Benefits of Nordberg C Series • High production • High reduction ratio • Easy maintenance • High uptime

Increasing the stroke, the power and the retaining force while improving crusher body design and weight to withstand the force are principles of kinematics. A higher density in the crushing chamber improves the inter-particle crushing action, resulting in superior product shape, high reduction ratio and high capacity.

R: Size reduction ratio. The ratio of the gape width to the near side jaw opening. This ratio may vary from 1/3 to 1/9, but is generally 1/3 for primary crushers and 1/4 for secondary crushers. θ: Nip angle. One of the most important parameters is the angle between the two jaws, which is referred to as the nip angle.

Mar 13, 2015· (2) (di/dn) = reduction ratio. If n=1.0 equation (2) becomes Kick’s theory. If n=1.5 equation (2) becomes Bond’s theory. If n=2.0 equation (2) becomes Rittinger’s theory. 19. Rittinger’s theory According to this theory energy E required for size reduction of unit mass is directly proportional to the new surface area produced.

Dec 25, 2017· The speed reduction ratio is 4.25 and the helix angle is 15º. The service is continuous and the teeth are 20º FD in the normal plane. Design the gears, assuming a life of 10,000 hours. [AU, Apr / May – 2010, Nov / Dec – 2016] 2.148) Design a pair of helical gears to transmit 20 KW at a speed reduction ratio of 4:1.

The M22 transmission has a 20 degree helix angle on the gear set as opposed to a 45 degree angle found on the M20 and M21 and were made with a higher nickel alloy. The straighter angle was designed to produce less end loading of the gear train and less heat but created more noise, thus the nickname "Rock Crusher" was born.

The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heat-treated before strength testing. This conclusion is drawn from a great number of experiments [1,2,4,8,9,11,17–19].The higher the temperature is, the lower the strength. Some results for uniaxial compressive strength σ c
