Closed-Side Setting Effect on Feed Size. Measurement of the crusher's closed side setting (CSS) varies depending on the jaw profile that is being used and has an impact on the crusher's capacity and product gradation. Diagram of closed-side setting effect on feed size [image: (135-5-13)]
Crushing devices hold feed material between two solid surfaces and apply sufficient force to fracture or deform that material. Primary crushing operations takes boulder size feeds (20 to 100 inches) and reduces the material to secondary crusher feed size (1 to 20 inches) or mill feed size (0.5 to 3 inches).
Rule #1: Identify maximum feed size. The size of the crusher opening directly determines the maximum feed size going into the crusher. For example, if the jaw has a 30-in. opening (gape), the maximum feed size …
Jaw crushers and cone crushers use a compression force while impactors and hammermills use an impact force. A jaw crusher is used in a wide variety of applications, including construction and recycling demolition, quarrying and mining, asphalt production, etc. This machine is a complex swing jaw crusher. The feeding port is equipped with a feeding hopper to prevent the material …
Crusher manufacturers publish grid charts, particle size cumulative distribution curves, and/or product size distribution tables to help predict the gradation of the crusher …
2. Feed opening "B" is at a minimum setting "A". 3. Maximum feed size vary from 80 to of "B" depending on the machine size and material. Each HP cone crusher has several cavity options with different feed openings and setting ranges. The correct cavity can be selected based on the feed size, setting and application.
The maximum feed size for a jaw crusher can reach 1,200 mm. They perform better than gyratory crushers on high-humidity, high-viscosity materials like clay, but often produce output with poorer particle shapes, such …
When selecting a two-stage crusher, feed size generally dictates if a Triple Roll Crusher or Quad Roll Crusher is the appropriate choice.
The 159 indicates a 548 crusher size with 1″ eccentric throw. With 1-in. eccentric throw, the motor hp allowed on the crusher is a maximum of 125. However, since only 90.3 hp is required for this average material, a 100-hp motor is sufficient. ... F the feed size or diameter in microns of the square hole which 80% of the feed passes, P the ...

CS430 cone crusher comes equipped with a Hydroset CSS regulation system that will automatically optimize production and keep track of liner wear. This means that your production levels are always as high as possible, with a minimum of downtime for ...
As the feed moves towards the drive end of the cone crusher, its size decreases (due to the crushing action), and ever smaller pieces move towards the drive end of the crusher. After passing through the crusher, the product -now at a much-reduced size- is discharged through an opening in the bottom shell.
The maximum feed size for a jaw crusher should be about 85% of the gape. Source: Arthur Taggart; The combination of a jaw crusher and a scalping grizzly will have 15% more capacity than a stand-alone jaw crusher. Source: Ron Casson; As a rule, scalping grizzlies are rarely used anymore for (large) primary crushers. The exception is when ore ...
The feed size, which often varies from small, fine pebbles to larger rocks up to 80 centimeters in diameter, greatly determines the crusher's throughput. Matching the feed size …
Among his findings were empirical models showing that crusher setting, feed size, crusher speed and throw affects particle shape in products from cone crushers. Increased average feed size increases flakiness index, likewise does decreased crusher speed. Further, Bengtsson states that in full-scale crushing, there is no evidence that feed shape ...
Figure 5 presents the feed size distributions of all surveys performed with the cone crusher. The significant variation in feed top size is evident. In addition, large proportions of fines were observed in the feed in selected surveys, suggesting poor screening efficiency in the respective operations depicted in the surveys.
Feed size was divided into two fractions of (+2.38 −4) and (+2 −2.38) millimeters, from which different feeds with different weight and size percent values were fed to mill at three feeds of ...
Jaw Crushers don't just eat anything. You can't just feed a jaw crusher everything you can fit in the trucks feeding it. Here below is is the …
Maximum material lump, or largest size expected to be crushed Tons per hour rate needing to be crushed Desired size of discharge material needed Operating hours per day. F100 is the maximum gape opening on a Jaw Crusher. F80 is the feed size to the Jaw Crusher, calculated by taking 80 times the gape opening divided by 100.
REFERENCE II Feed Size. In the case of a primary crusher this may be somewhat difficult to obtain. Experience indicates, however, that in most cases 80% of the feed size will pass a square opening equal to from half to two-thirds of the crusher receiving opening.

Determine the feed size as the size, square mesh in inches, through which 80 percent of the fed material will pass. Determine the product size as the size, square mesh in inches, through which 80 percent of the product will pass. If screen analysis is not available, use this graph to estimate screen analysis of crusher.
Jaw Crushers typically have a reduction ratio of 6:1, which means a 30" feed will be reduced down to 5" at the smallest size. The product size can be adjusted by opening or closing the gap between the jaw dies at the …

Crusher Operation • Relation between Feed size and Shape – The greater reduction ratio the worse particle shape. – Inter particle breakage improves shape. When crushing a bed of material weaker particles will break first. Flaky or elongated particles are weaker then round. – Breaking round particles gives flaky material. F l a k i n e s ...
