Typically, the minimum setting on most primary crushers will be about 4 to 6 inches, as noted above. Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types. 2. Secondary Crushing.
When tackling a tough hard rock application, choosing the right crushing equipment can make or break the project. The primary crusher plays an essential role, as it reduces the size of large rocks and prepares them for further processing. Two types of primary crushers in the industry stand out: gyratory and jaw crushers.
fixed concave surface and a movable mantle. The bigger rock material is crushed against the mantle and the concave. The crushing action is caused by the clos-ing of the gap between the moving mantle liner mounted on the central vertical shaft and the fixed concave liners mounted in the top shell of the crusher. The gap is opened
Beyond the primary stone crusher and secondary crushers, screeners play a vital role in the stone-crushing process by grading the crushed material by size. Screeners, or screening equipment, are integral to this process. They work by sorting crushed stones into various size categories using vibrating screens or mechanical separators.
The entire design facilitates lubrication and replacement of shaft bearings. Jaw plates are constructed of manganese steel and have corrugated crushing surfaces which reduce the power required for fracturing material. The jaw plates are built into two pieces to jaw. Those on the swing jaw are interchangeable.

Impact crusher is a kind of crushing machine which uses impact energy to break materials. It is suitable for handling brittle materials of medium hardness with side length not exceeding 500mm and compressive strength not exceeding 350 mpa. The impact machine has the characteristic of large crushing ratio, low energy consumption, high efficiency ...

Eastmancrushing understands crushing and grinding machines well. We are one of the leaders in rock crushing in China for about 40 years. We're proud to offer a line of rock crushers that provide a wide range of options and fit a variety of applications. From reducing the size of large rocks to gravel, grinding rocks to table salt size, or ...
Cone crushers consist of a circular outer concave enclosing a cone-shaped mantle that moves eccentrically, see Fig. 1. As the distance between the mantle …
Roll Crushers. Single roll crushers, shown in Figure 7, use shearing action to break soft rock. The main part is a knobbed roll where the knobs extend 3 to 4 inches beyond the roll surface. Rock is caught between the roll and the stationary breaking. plate where it is continually hit and pushed by the roll knobs.
Cone Crusher Structure and Functional Principle. The crushing chamber is composed of the mantle and concave, as shown in Figures 1(a) and 1(b). The drive turns the horizontal countershaft. ... W. Xu, X. Zhuang, and T. Rabczuk, "Three-dimensional mesoscale computational modeling of soil-rock mixtures with concave particles," …
5.1 Structure of Crusher Analysis ... In a cone crusher the rock material is crushed between rigid surfaces. ... The mantle is fixed to the main shaft and the concave to the crusher frame. ...
rock crusher structure concave Cone Crusher Mineral Processing. Structure. The main parts of the cone crusher are bowls, mantle, eccentric components, linings, etc. and the operational part of the cone crusher is the crushing chamber, which consists of concave and mantle. US720853A - Concave for rock crushers.
The distinguishing features of this type of crusher concave are: The receiving opening, for any given size of crusher, is at a maximum. The choke-point (point of minimum capacity) is at the discharge opening. The ratio of reduction varies for different sizes, ranging from about 5 to 8 and averaging about 6.5 for sizes from 8″ to 42″ inclusive.
The minimum distance between the mantle and concave is defined as the closed side setting (CSS) of the cone crusher. The CSS is easily changed online in a large variety of commercial crushers; different principles of CSS adjustment are described in (Quist, 2017).The maximum distance between the mantle and concave, on the other …
can help make sure that your cone crushers are operating with the ideal crushing chamber. Throughout our Crushing Chamber Application Guide there are look-up …
Schematic diagram of cone crusher showing the cone (mantle) and bowl (concave); (a) full crusher. The mantle is green, the concave is brown and the feed structure is purple, whilst the liners are coloured with a slightly darker shade to the objects they are attached to, and (b) close-up of the crushing region. ... The predicted rock …
A gyratory crusher consists of a concave sur-face and a conical head; both surfaces are typically lined with manganese steel. The top of the shaft attached to the crushing cone …
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 …
There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...
The crusher is the workhorse of the hard rock crushing industry. A gyratory crusher uses a mantle that gyrates (rotates) within a cone shaped inner surface lined with wear resisting plates often called concaves. As the mantle gyrates within the crushing chamber, progressively approaching, and receding from, each element of the cone ...
I have experienced many problems due abnormal power draw behavior of the electric motor in a primary gyratory crusher in iron ore crushing, especially when the service life of the first row concave comes to an end. I suspect that the current eccentric throw of the mainshaft (52mm) is higher than is really necessary.
The operational part of the cone crusher is the crushing chamber, which consists of a mantle and a concave liner. As shown in Fig. 1, the axis of the mantle intersects the axis of the crushing chamber at point O, which is the pivot point.The angle between the two axes is γ, which is the eccentric angle.During operation of the crusher, …
4. Keep the Operator Isolated. To ensure industrial rock crusher safety, operators can use an enclosed booth or a remote control station to remain isolated from dirt and debris that could harm the body or lungs. An enclosed cab should: Be well-sealed. Have proper ventilation.
2. Cone Crusher Structure and Functional Principle. The crushing chamber is composed of the mantle and concave, as shown in Figures 1(a) and 1(b). The drive turns the horizontal countershaft. The …
The primary contributor to poor crusher performance is crushing chamber selection. If the fit between the mantle and concave – in combination with the eccentric throw setting – is incorrect, then the optimal reduction ratio cannot be achieved.
The importance of the right mantle and concave. If you are using an incorrect crushing chamber then you are compromising on productivity, liner life or both. A crushing chamber that is too small will either deliver a low reduction ratio or completely fail to function. On the other hand, if your crushing chamber is too big, then material will ...
The eccentric throw is one of the most important parameters in defining the job that your cone crusher does. The mantle in a cone crusher spins in conical pendulum motion. That means it doesn't stay in the center of the chamber – it sweeps around moving closer and further away from the concave. This is what creates the crushing action. At a ...
