Hersam (1923) proposed a method for calculating capacities using a Dodge-type jaw crusher. The equation proposed by Hersam includes a number of constants that are only qualitatively related to the machine and material characteristics.

The volume of material (V) that passes through the crusher bottom opening per stroke is given by: V = w(S+T/2)a (1) If the machine is run at low speeds, the movement of the jaw allows sufficient time for the material to fall through under gravity, with the distance of fall depending on the geometry of the machine.

 — Stroke Length: The stroke length is the distance that the movable jaw plate travels during each cycle of the crusher. A longer stroke length can increase the amount of material that is crushed per cycle, which can improve throughput and reduce the risk of material slipping. ... Calculate the required capacity of the jaw crusher by considering ...

The NIH Stroke Scale has many caveats buried within it. If your patient has prior known neurologic deficits e.g. prior weakness, hemi- or quadriplegia, blindness, etc. or is intubated, has a language barrier, etc., it becomes especially complicated.

The crusher closed side setting is infinitely adjustable within setting limits through the actuation of hydraulically controlled wedges and tension rod spring. The wedge assembly is fully contained within the crusher frame. A hydraulic power pack, positioned close to the crusher, provides push button control. Main shaft

 — Calculate Crusher MOTOR HORSEPOWER. Crushing horsepower required is dependent on the hardness and toughness of the material, the ratio of reduction, product size, and the specific gravity. …

 — Evertsson (2000) proposed that determining the nominal stroke and bed thickness at each point of the cross-section of the chamber to calculate the compression ratio of the crusher. The ratio between the stroke and bed thickness is referred to as the nominal compression ratio.

 — Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are application drawbacks that may make another crushing solution more appealing. First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less).

1. Normally the size reduction by crushing is of limited importance besides the top size of the product going to grinding.
2. This means that the number of crushing stages can be reduced depending on the feed size accepted by primary grinding stage.

 — Calculate the Capacity: Calculate the required capacity of the jaw crusher by considering the throughput rate, the size and shape of the material being processed, and the specific gravity of the material. …

 — Eloranta (1995) reported that the crusher stroke and eccentric speed do not have a large influence on the product flakiness, based on a study with a small sample size. Other authors reached different conclusions. ... This map can potentially help calculate optimized operating crusher conditions for different feed characteristics, market prices ...

 — The following example outlines the steps and information needed to calculate Roll Crusher Capacity. First, determine the peripheral speed. In this case, the peripheral speed is measured to be 50 m/min. Next, determine the width of the rolls. These rolls are measured to be 2 m wide.

 — A jaw crusher, like 2036 in the Jaw Crusher Table here above, would be able to take the maximum 12 in. size quarry stone but it would not have the required 70 tph capacity needed. To have the needed capacity a jaw crusher like the 2042 or 2436 sizes will have to be selected overloading the secondary crusher.

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.

Calculate engine displacement and the size of a motor using our calculator. Plus, learn the formulas and methods to calculate it yourself. ... If the bore and stroke measurements are in inches, then the result from the formula …

 — Remember, this calculation does not account for waste, so you can add about 10% if you'd like extra. Frequently Asked Questions (FAQ) FAQ. What is the weight of one cubic yard of crushed stone? A cubic yard of crushed stone measures a 3 feet x 3 feet x 3 feet area and weighs about 1.35 to 1.5 tons.

 — The calculation results of the existing cone crusher productivity are compared with the actual production results. The calculation results are always greater than the actual production results. After analysis, because the crusher has a blockage layer in actual work, the mantle far away from the concave will fall.
