The value S of the width of the discharge port: the coarse crusher is different from the ...
For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide. Perhaps it will be more effective to use one continuous screen of at least 20.1 + 15.2 = 35.3 sq ft.

A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary …
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 crusher discharge opening governs the size of finished material produced by ...
Typically the rotor diameter to the size of the ore block ratio of 4 to 8, a large crusher is approximated to 2. Since Φ800 × 900 hammer crusher for medium crushing machine, so to diameter ratio of the size of the ore block to take 7, and processed material size ≤120 mm. Therefore, the rotor diameter D = 6 × 120 = 720mm, D = 800mm take

Estimate Jaw Crusher Capacity. Example capacity calculation of a 10″ x 20″ (250 mm x 500 mm): = 2800 x 0.25 x 0.5 x 0.5 x 225 x (1-0.2)/60 = 525 kg/hr = 13 TPD vs 300 to 420 TPD —> I can't make this work! My friend Alex the SAG Mill Expert, says this equation you picked up doesn't look right.
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 feed size passing 80 per cent versus the discharge size that passes 80 per cent.
The difference between the cumulative percentages at the 3.5″ and 1.5″ points on the curve gives us the amount, of such product to be expected from the output of the primary crusher This is 85 minus 43, or 42% of the primary crusher product. If our problem had covered a crushing condition calling for 80 instead of 85% passing the …
Cone Crushers deliver a 4:1 to 6:1 reduction ratio. A Cone Crusher with coarse-style liners would typically have a 6:1 reduction ratio, though reduction ratios of 8:1 may be possible in certain coarse crushing applications. Fine liner configurations typically have reduction ratios of 4:1 to 6:1.
What is a good reference for the dimensioning of these types of crusher: gyratory, cone, VSI, HSI?
Hydraulic Cone Crusher. The hydraulic cone crusher is a modern and advanced version of the spring cone crusher. It uses hydraulic cylinders to adjust the size of the crushing chamber and control the discharge opening. The hydraulic cone crusher is known for its high efficiency, low maintenance requirements, and excellent crushing …
Discharge flow of water increases as tube diameter decreases and submergence ratio increases. At high submergence ratio, water discharge is induced relatively easily even by low air flow. At the same time, slug flow regime is extended farther into high air flow as observed from change in bubble flow pattern in the preceding section.
2. Surface crushing ratio: the ratio of the width of the feed inlet of the crusher to the width of the outlet. Calculation formula: 1=0.85B/S (inlet width/discharge width referred to here) 0.85 is the width coefficient of the material contained in the crusher. The value of the width of the discharge port is S: the coarse crusher is different ...
