Gyratory crushers are principally used in surface-crushing plants. The gyratory crusher (Figure 6.5) consists essentially of a long spindle, carrying a hard steel conical grinding element, the head, seated in an eccentric sleeve.The spindle is suspended from a "spider" and, as it rotates, normally between 85 and 150 rpm, it sweeps out a conical path within the fixed crushing …
Jaw crusher feed should be pre-screened using a grizzly prior to crushing to remove any material finer than the closed-side setting. Cone and gyratory crushers. Cone crushers and gyratory crushers are also compression-type machines that crush material between a moving piece of steel and a stationary piece. The output is controlled by the ...

The cone crusher is a modified gyratory crusher, and accordingly many of the same terms including gape, set, and throw, apply. The essential difference is that the shorter spindle of the cone crusher is not suspended, as in the gyratory, but is supported in a curved, universal bearing below the gyratory head or cone (Figure 6.8).Major suppliers of cone crushers include …
A sectional view of the single-toggle type of jaw crusher is shown below. In one respect, the working principle and application of this machine are similar: the movable jaw has its maximum movement at the top of the crushing chamber, and minimum movement at the discharge point. The motion is, however, a more complex one than the Dodge motion, being …
A fter spending over 40 hours and crushing over 1,000 soda cans we determined that Easy Pull's auto-dispensing is the best . The Easy Pull proved to be quick, simple to use and very affordable. Additionally, its design for crushing cans virtually eliminates the risk of cutting your fingers on a ragged edge.
Figure 5.1 is a typical sketch of a large gyratory crusher used as a primary crusher to reduce the size of large pieces of rocks produced during blasting in mines. Variations in the design of the breaking head and the mantle have been adopted by different manufacturers. Such variations are adopted from studies on stress distributions of component parts endured during …

The Jaw Crusher was first introduced by Eli Whitney Blake in 1858 as a double-toggle Jaw Crusher. Introduced in 1906, McLanahan's Universal Jaw Crusher was one of the first modern era overhead eccentric Jaw Crushers. On the overhead eccentric style Jaw Crusher, the moving swing jaw is suspended on the eccentric shaft with heavy-duty double ...
Choosing the right type of primary crusher for your operation depends on several factors, including the maximum size of the material to be crushed, the desired output size, and the capacity of the crusher.
Impact crushers are traditionally classified into two main types, horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers. These different types of impact crushers share the crushing principle, impact, …
Knowing which crushers best fit in each stage, as well as ensuring a properly sized crusher for the task, will help a site achieve optimum crushing efficiency and overall profitability.

A large primary crusher is more expensive to purchase than a smaller machine; for this reason, investment cost calculations for primary crushers are weighted against the costs of blasting raw material to a smaller …
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 through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m; Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate: 160 to 13,000 tph
material in a particular crusher, they should be independent of the closed side set. This allows the crusher performance to be simulated at the various CSS. Model based on: 1. Whiten W.J. Walter G.W. and White M.E. A breakage function suitable for crusher models. 4th Tewkesbury Symposium, Melbourne (1979) p 19.1 - 19.3. 2. Whiten W.J.
The Crusher throw is defined as the distance in the direction of compression the moving crushing surfaces/plates travel from OSS to CSS. Throw = OSS – CSS. OSS and CSS will define a crusher's performance. The throw of the crusher is the distance that moving jaw moves in going from OSS to CSS. The capacity is a function of size and OSS.
Crusher run drains faster than dense-graded bases, but slower than open-graded materials. Appearance and Color. Crusher run is typically grey in color with a blend of stone sizes visible. The color may vary depending on the quarry rock type. Uses and Benefits. Crusher-run gravel provides valuable properties for many construction applications:
Since the selected crusher capacity must be in excess of 143 tons per hour, the next higher figure (159) is chosen. 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 ...
The hydraulic jaw crusher is ideal for crushing hard and abrasive materials, and it is commonly used in mining, metallurgy, building materials, and chemical industries. One of the advantages of a hydraulic jaw crusher is its ability to adjust the discharge opening easily, allowing for a wider range of output sizes. ...
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 transported …
An individual crusher's construction and capabilities also dictate where in your processing operations it will fit. That is, you may have multiple types of crushers situated in primary, secondary, and tertiary stations in a circuit format to perform the necessary material reduction work.

A gyratory cone crusher consists of a mantle and a concave surface, which are both lined with wear-resistant materials. The mantle gyrates within the concave, creating a crushing chamber that reduces the feed material to the desired size. The size of the crushed material is determined by the distance between the mantle and the concave at their ...
Crusher Run gravel-- also known as 'Crush and Run', 'Crush N Run', 'Graded Aggregate Base' (GAB), or 'Aggregate Base Coarse' (ABC Stone) -- has perhaps even more useful applications than it does names it goes by.
