A well-graded feed for a Jaw Crusher includes material larger than the closed-side setting but no larger than 80% of the feed opening. As stated in the two previous best practices, remove oversize, fines and material equal to the product size ahead of time for optimum operation.
The capacity of the crusher is determined by its size. The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios ...
Higher reduction ratio: Gyratory cone crushers are capable of producing a finer product than jaw crushers, due to their larger size and higher horsepower. Uniform particle size distribution: The crushing chamber of a gyratory cone crusher is designed in such a way that the particles are subjected to a uniform force throughout the crushing …
The Fairmount crusher is inherently a somewhat cleaner breaking machine than either the standard gyratory or standard jaw types, but the class of rock for which the former crusher is largely used is …
The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. It …
For example, a 40- x 51-in. jaw crusher calls for a maximum feed size of 32-in., a CSS range of 4- to 8-in.; and produces a desired product size that fits within that CSS range. While various crusher sizes have similar CSS range spans, some crushers operate in a bit tighter CSS range than others. The key is looking at the desired …
Here is what a well choke fed jaw crusher looks like! Too many mines run these jaw crusher cavity like a funnel without any choking. Operators must keep the jaw's cavity full to maximize rock-on-rock compression and crushing. Notice the shape of the liner profiles? A crusher is choke fed when the chamber is full ... Choke Feeding a …
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. Since the gyratory, unlike the jaw crusher, crushes on full cycle, it has a higher capacity than a …
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 …
Due to their smaller physical size, jaw crushers are also ideal for tight spaces, such as underground mining and mobile crushing applications, where some other primary crushing solutions simply do not fit. Types of Jaw Crushers. Jaw crushers have been around for nearly 200 years at this point and are one of the most "historic" crusher types ...
All the benefits of a gyratory crusher – with the largest feed opening . The Jaw Gyratory Crusher Pro is engineered to handle bigger chunks of material than comparable gyratory crushers of the same mantle diameter. This gives you greater flexibility in your crushing operation, and reduces the tendency for bridging in the feed zone.
Disadvantages of a Jaw Crusher. Jaw crushers can also have some disadvantages compared to other types of size reduction. ... The size of the jaw plates limits the particle size capacity and determines the size of the feed opening. In general, maximum particle sizes are about 70-80% of the feed opening, but this can vary by manufacturer and ...
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 …

Each jaw crusher comes with feed hopper, feed hopper interface, drive and subframe with v-belt guard and motor bracket, our unique guarding retraction arrangement and toggle plate stop. The wide range of jaw plates can be mixed and reversed to ensure optimal, versatile crushing.
1. What model jaw crusher do I need? Determining the model of the jaw crusher depends on various factors: a. Feed size: The material size should not exceed the maximum feed size of the crusher model. b. Desired product size: Different models have different maximum output sizes. Ensure it can produce the final size.
Initial Feed Size Size Reduction Process Details; Primary Crushing: To reduce large and bulky materials to a manageable size. Jaw Crusher: 500 mm to 800 mm: Reduced to about 125 mm to 150 mm. Large chunks of material are fed into the jaw crusher where strong compressive forces break them down. Secondary Crushing
One really handy thing about jaw crushers is that you can change the size of the end product by shifting the discharge opening's spot. Because of this tweakable feature, jaw crushers can adapt to a bunch of different crushing needs. ... They're built to take on big feed materials — we're talking rocks up to a meter (three feet) across ...
For example, if the maximum feed size is 29"x49", the crusher gape would be 32" and the width would be 54". By sizing the Jaw Crusher slightly larger than the largest feed size, you reduce the risk of large lumps getting stuck in the crushing chamber or sitting on top of the crushing chamber, stalling production.

2. Choke feeding. Jaw Crushers work best when the entire crushing chamber is used for material size reduction. Choke feed a Jaw Crusher to maintain a crushing chamber that is at least 80% full. This will help to draw the material down into the crushing chamber, as well as create a better material shape and improve overall …
Owing to the wear resistance, large output, and uniform product cube, the cone crusher is used in secondary, tertiary, and quaternary crushing, with the jaw crusher and gyratory crusher used for primary crushing. However, a cone crusher can also perform primary crushing if the feed size is small enough.
Feed size, which is around 150 to 300 mm, of the rock or ore from the primary crushing process is reduced to between 50 and 80 mm. ... A comparison of jaw crushers with the same capacity reveals that double-toggle jaw crushers are more expensive than ordinary jaw crushers. For this reason, mostly single-toggle jaw crushers are used in the ...
