Crushing angles in standard Blake-Type machines generally run in the neighborhood of 27 deg, at the minimum open-side discharge setting. The ratio-of-reduction at minimum recommended settings and with straight jaw plates average about 8:1, in the range of sizes from 15- x 10-in., to 60- x 48-in,, inclusive.

Product size, or crusher discharge setting. Type and size of quarry equipment. Methods employed in drilling and blasting. Method of feeding the crusher. The first three of these factors will almost always be ascertainable at least to a close approximation before the matter of crusher choice is taken up.
The chief difference between cone and gyratory or jaw crushers is the nearly parallel arrangement of the mantle and the cone at the discharge end in the cone crusher. This …
The superior gyratory crusher's discharge setting is referred to as the Open Side Setting (OSS). This is a single pre-determined setting at which the crusher and it's crushing chamber are designed to operate. The setting cannot be operationally changed to produce different product sizes instead
The crusher discharge P80 product size needs to remain less than 1/3 of the related conveyor belt width. ... The rated capacity at 5" closed-side setting was 490 stph based on standard 100lbs/ft3 feed material. These crushers were fed a very fine ore over a 4″ grizzly which allowed the 1000 TPH the SAG mills needed.
1. Operate at a consistent closed-side discharge setting. Producing a consistent product quantity, quality, uniformity and attaining a balanced circuit begins …
In the Gyratory crusher, bottom discharge design makes possible a compact, squat structure of simplified design and comparatively high strength. …
The jaw crusher operates at slower speeds and tries to compress and compact material rather than explode it. In addition, the jaw crusher would be used to crush hard material such as granite whereas impact crushers are used to process softer materials. ... The feed opening, discharge settings, horsepower and cost of the machine are all ...
In this paper the effect of crusher type and crusher discharge setting on washability characteristics of same crushed non-coking coal has been studied. Thus four different crushers were investigated at variable parameters like discharge settings, different capacities and feed openings. The experimental work conducted for all …
This is especially true for high reduction ratios and close discharge settings; it is the reason why the careful crusher builder always cautions against feeding unscreened material to fine-reduction crushers. It is also understandable why it is advisable to use reduced throw eccentrics for settings below the manufacturer's recommended minimums.
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction …
Additionally, feed material and crusher settings go hand in hand with crushing efficiency. Adcock advises operators to make sure the feed size is correct for their crusher and to eliminate fines from being fed into the jaw. By pulling out fines, operators will ensure processing efficiency and yield a higher quality material at the discharge point.
With a gyratory crusher, at any cross section there are in effect two sets of jaws opening and shutting like jaw crushers. In fact, the gyratory crusher can be regarded as an infinitely large number of jaw crushers each of infinitely small width, and, as consequence, the same terms gape, set, and throw, have identical meaning in the case of the gyratory crusher.
The Gator 6x10 Jaw Crusher, 25HP Motor, Max feed size 4-7/8" rock, up to 5 TPH, Discharge setting: 3/8" to 1-1/2". Website for Arizona Construction Equipment, Inc. Search for:
Concaves on the right illustrate the cross section of a typical gyratory crusher, while the left illustrates the same crushing chamber, except that, in place of the straight-face concave, the non-choking type has been substituted.For the sake of direct comparison we have shown the same discharge setting in both diagrams, although a …
Checking and adjusting the jaw crusher's closed side setting. Checking and replacing the wear parts such as the jaw dies, toggle plate, and bearings. Inspecting and cleaning the crusher's belts and pulleys. Lubricating the crusher and its parts as recommended by the manufacturer. Common Jaw Crusher Maintenance Issues and …
The cone crusher working principle involves the eccentric motion of the main shaft. This motion is created by the rotation of the main shaft, which is supported by a …
According to Bearman, the length of the crushing chamber affects the included angle (angle between the crushing plates) for any particular crusher feed and discharge setting . A short cavity, alongside a tight set opening, poses a risk of an upward slippage of charge material during the compression cycle.
Generally, the size of the discharge material can be controlled by adjusting the crusher plate and wedge block. The adjusting plate is generally located behind the …
Adjusting the discharge opening of an impact crusher is an important maintenance task to control the size of the crushed material and ensure the crusher operates efficiently.
Depending on cone crusher, setting can be adjusted in two ways. The first way is for setting adjustment to be done by rotating the bowl against the threads so that the vertical position of the outer wear part (concave) is changed. ... limiting the capacity as compared with the discharge circuit of a gyratory crusher. Jaw crushers are mainly ...
Whether or not it is advisable to set the crusher to a discharge opening equal to the product size depends upon the crushing characteristics of the material. If the material is friable, or if it cubes well, it is safe to assume that the crusher can be so set; on the other hand, if it is hard, or tough, or tends to slab in the crusher. the ...
The roll crusher consists of a pair of horizontal cylindrical manganese steel spring rolls (Fig. 13.14), which rotate in opposite directions. The falling feed material is squeezed and crushed between the rollers. The final product passes through the discharge point. This type of crusher is used in secondary or tertiary crushing applications.
It comes out the bottom discharge opening. The adjustment ring changes the size of the discharge opening. It does this by changing the distance between the mantle and bowl liner. This determines the size of the final product. ... The final size of the crushed product is determined by the cone crusher's closed side setting (CSS). With …
Check that the discharge area is free of buildup. Also, check the discharge setting on the jaw crusher and inspect the toggle plate for cracks. Listen for any knocking sound from the toggle while the crusher is running empty, and adjust the toggle as needed. Check for any unusual vibration while the crusher is running empty.
Changing the position of the mantle changes the gap setting at the outlet of the crusher, and consequently the size of the crushed output. The height of the mantle is often automatically adjusted based upon the torque produced, and has a release mechanism that allows the mantle to drop should the normal workload be exceeded; this is an overload ...
The transportable chassis offers easy movement between locations and rapid on-site set up. Incorporating the well proven fully hydraulic Parker Cone Crusher, this unit is ideal for working in a composite crushing arrangement with Parker primary crushing plants, screens and conveyors. Full mobile or transportable options; Fast on-site set up
Obviously these different requirements may call for setting up a comparison between different sizes of one or the other type. Usually, in selecting the primary crusher, receiving opening is the prime consideration; admitting of course that capacity must be adequate. ... The gyratory crusher by virtue of its annular discharge opening is an ...
The closed-side setting of a jaw crusher helps determine the nip angle within a chamber, typically 19 to 23 degrees. Too large of an angle causes boiling in the …
