Jaw crusher movement is guided by pivoting one end of the swinging jaw. and an eccentric motion located at the opposite end. [4] The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws .For instance, a 22 x 30 jaw crusher has an opening of 22" by 30", a 46 x 46 jaw crusher has a opening of 46" square.
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.

It is entirely possible for a crusher to choke at some other point in the crushing chamber than the theoretical choke-point. When the setting of a fine-reduction crusher is too close for its eccentric throw and for the general proportions of its crushing chamber, there is a tendency toward building up a choke in the zone immediately above …
Curved plates are sometimes used to prevent choking near the crusher discharge, which can occur if fines are present in the feed. The lower end of the swing jaw is concave, while the lower half of the fixed jaw is convex, allowing for a gradual reduction in size as the material nears the exit, minimizing the chance of packing.
Fine jaw crusher is also called "jaw crusher" and belongs to the "pe jaw crusher" series.The difference from pe jaw crusher is that the discharging granularity is different.

The crushing process continues until the material is small enough to pass through the bottom opening of the crusher. This opening is called the discharge port and it controls the …
How you select your primary crusher will be based on factors like moisture content, maximum rock lump size, material density SG, abrasion index, degradability and it being prone to dusting or not. The crusher capacities given by manufacturers are typically in tons of 2,000 lbs. and are based on crushing limestone weighing loose about 2,700 …
Most cone crushers have a feed opening size of 5-14", so material that's larger than the maximum size allowable will need a first stage of crushing before they can be fed into a cone crusher. Final …
A striking feature of the non-choking concave, is the character of the product. So far we have been dealing with crushers whose eccentric speeds are low enough to permit the material to fall, with each receding stroke of the active crushing member, the full distance allowed by the close CSS and open side OSS physical …
Cone crusher is one of the mainstream crushing equipment in mining industry. It is mainly used for medium or fine crushing for various kinds of raw materials. The output size of cone crusher is determined by the distance between mantle and concave. But many people don't know much about the discharge adjustment dvice of …
Discharge Opening: Once the material reaches the desired size, it exits the crusher through the discharge opening at the bottom. The adjustable nature of the discharge opening allows for ...

In the history of crushers, both chronologically, and by virtue of its standing in the field of heavy-duty crushing, the Blake jaw crusher stands first in the list. All of the large, heavy-duty primary crushers of the jaw type are built around the Blake principle which, for simplicity and brute strength, is unsurpassed by any mechanism thus far …
In this article, we mainly talk about the check and adjustment of discharge opening in jaw crusher. Jaw Crusher Discharge Opening Check. Generally, the check of jaw crusher discharge opening can be carried out through lead ball (or lead block). In order to hold the lead block conveniently, we can cast it into a small ball or cylinder.
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 …

Crushers. Barry A. Wills, James A. Finch FRSC, FCIM, P.Eng., in Wills' Mineral Processing Technology (Eighth Edition), 2016 Jaw-crusher Construction. Jaw crushers are heavy-duty machines and hence must be robustly constructed. The main frame is often made from cast iron or steel, connected with tie-bolts. It is commonly made in sections so that it can be …
Instead a wedge is driven around to create compression on one side of the chamber and discharge opening on the opposite side. …
the crusher setting: the discharge opening between the jaw plates farthest down in the crushing chamber, measured in the same way as the feed opening, when the discharge opening is in the fully closed position; the nip angle: the angle between the fixed and moving jaw plates, this angle must not be greater than the optimum

In terms of structure, it is much heavier than the single-cylinder hydraulic cone crusher of the same specification. The maximum feed size is 241 mm, which is smaller than other crushers. It controls the output size by reducing the size of the discharge opening, so it is not suitable for use for ultra-fine crushing and sand making operations.
The primary gyratory crusher offers high capacity thanks to its generously dimensioned circular discharge opening (which provides a much larger area than that of the jaw crusher) and the continuous operation principle (while the reciprocating motion of the jaw crusher produces a batch crushing action).
