Crusher Concave Liners and Mantle Wear A perfect example of this is the wear on the concave liners and the mantle The angle between the concave liners and the mantle is at its best operating position when they are new As time and tonnage go by both wear Soon the pattern that the
Gyratory Mantles and Concaves. Gyratory mantle and concave design is pivotal to downstream process efficiency. Due to inconsistent feed size, fines ratio, clay content, moisture and throughput rates, gyratory crushers have inherent problems of poor wear predictability of both mantle and concaves and excessive wear in the lower chamber.
The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the machine are ...
Maintenance of the wear components in both gyratory and cone crushers is one of the major operating costs. Wear monitoring is possible using a Faro Arm (Figure 6.10), which is a portable coordinate measurement machine.Ultrasonic profiling is also used. A more advanced system using a laser scanner tool to profile the mantle and concave produces a 3D image of the crushing chamber (Erikson, 2014).
Comminution by gyratory crusher is the first stage in the size reduction operation in mineral processing. In the copper industry, these machines are widely utilized, and their reliability has become a relevant aspect. To optimize the design and to improve the availability of gyratory crushers, it is necessary to calculate their power and torque accurately. The discrete element method (DEM) has ...
While the pivot point for the gyratory crusher is at the spider cap. This difference in the pattern of gyration has a purpose. The primary crusher produces a product that is gauged by the size of the open side of the mantle. ... Cone crusher mantle/concave. 1 like.

Apr 24, 2014 The gyratory crusher met the capacity requirements of 26003000 tons per hour nicely. However, there were high power spikes that could reach as high as 1000 kW, especially when crushing with somewhat worn wear parts. Power spikes and mantle cracks as challenges
May 08, 2018 Multiplying the wear life of the mantle and the concave segments. Jarkko Kettukangas, Department Manager of Materials Handling at Terrafame, has some impressive figures to share regarding the wear-life improvements of the primary gyratory crushers wear parts. The development of the primary gyratory wear parts together with Metso has been outstanding.
According to the company, this has increased concave life by as much as 300% between changes, with the useful life of mantles increasing in a similar range. It is also important to KCGM to have the guaranteed availability of the primary crusher at high levels. Metso upgraded the primary crusher from a Superior Mk1 gyratory to a Mk2 model.
Feb 28, 2013 The gyratory crusher met the capacity requirements of 2, 6003, 000 tons/h, except for the challenges caused by high power spikes. These spikes could reach 1000kW, especially when crushing with worn wear parts. In many cases, the original mantles had cracked prematurely, causing unexpected production stops. As a critical component of Jelsa ...

Gyratory Crusher Mantle. The gyratory crusher mantle is the major wear part of the gyratory crusher. The mantle which is the movable working surface is pivoted at its top within a spider bearing under the cap of the spider arm assembly while the bottom is gyrated within an eccentric bushing which is powered by the drive assembly.

It is strongly advisable to never place a new concave liner in a crusher with a worn mantle or a new mantle in a crusher with a worn concave liner. Mating new and worn components will change the profile of the crushing chamber and restrict the feed from entering the crushing chamber, which will reduce the output per hour produced.
gyratory crusher mantle concave profiling. Crusher Concave Liners and Mantle Wear A perfect example of this is the wear on the concave liners and the mantle The angle between the concave liners and the mantle is at its best operating position when they are new As time and tonnage go by both wear Soon the pattern that the ore takes through the crusher begins to change
The majority of gyratory crushers are used as primaries, i.e. they receive the initial feed from the mine or quarry. The same type of crusher with chamber modifications is used as a secondary crusher, particularly when following a large primary crusher. The fine-reduction gyratory crusher can also be used for tertiary crushing.
Ultrasonic profiling is also used. A more advanced system using a laser scanner tool to profile the mantle and concave produces a 3D image of the crushing chamber (Erikson, 2014). Some of the benefits of the liner profiling systems include improved prediction of mantle and concave liner replacement identifying asymmetric and high wear areas measurement of open and closed side

May 22, 2019 Metso 4265 Gyratory Crusher. May 22, 2019 April 6, 2021 itsd. A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. There are five types of crushers Jaw crusher, Gyratory crusher, Cone crusher, Impact crusher and Mineral sizers. A gyratory crusher is consisting of a concave surface and a conical head ...
Secondary, tertiary and quaternary crushers are generally gyratory, or cone, crushers. These operate on the principle of a steel mantle mounted on an eccentric bearing and vertical shaft assembly. Rotation of the eccentric assembly makes the mantle gyrate within a static outer concave. There is a gap between the mantle and the concave.
For larger concaves, Columbia Steel also said its important to remember that by handling fewer segments, it takes less time to reline a gyratory crusher. Recognizing the value of fewer, large concave segments, they have manufactured double height, double

Dec 24, 2020 Cone crusher liners include mantle and concave. Mantle Covers the cone head of the crusher to protect it from wear. It is the inner sacrificial wear liner that sits on the cone head. Concave Sits in the upper frame of the crusher to protect it from wear. It is the outer sacrificial wear liner that sits inside the upper frame. They are the ...
Cone Crushers. A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point.

What Affects Cone Crusher Performance Sandvik Mining
The gyratory crusher has capacities starting from 1200 to above 5000t/h. To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier. Therefore, primary gyratories require quite a massive foundation. The cone crusher is a modified gyratory crusher.
On this basis, the impacts of the mantle shaft angle, the concave angle, the eccentric angle, and the mantle shaft speed on the gyratory crusher performance are explored by the method of ...

Met Dynamics, in association with Bear Rock Solutions, has developed a sophisticated model of gyratory and cone crushers that can greatly aid the optimisation of process performance through the mechanical design of the crushers and liners.. The Kinematic Crusher Model (KCM) meshes a mechanical description of the crushing machine with the breakage characteristics of the feed material.
This action causes the gap between the mantle and concave liners to open and close upon each rotation of the shaft. At the upper end of the mantle this movement is very small, but as the feed falls lower, the throw increases and the crushing force also correspondingly increases. Cone
Concave and Mantle are the spare parts of Cone crusher. We use high manganese steel with chrome as material. Concave is installed at the top of cone crusher crushing chamber. All stones or mineral ores are crushed between it and mantle, so it is the main quick spare parts of cone crusher. With the concave, the body of machine can be protected well.
