Jaw Crushers
Jaw crushers are large-scale, heavy-duty machinery typically constructed with cast iron and/or steel. Jaw crushers often used to reduce rock into non-uniformed gravel.
Large amounts of material are fed into the “V-shaped” jaw of this crusher and are reduced using compressive force. One side of the V remains stationary while the other side of the V swings against it. The material is forced from the wide opening of the V to the narrowest point of the V creating a crushing motion.
Cone Crushers
Cone crushers are one of the main choices for secondary crushing. A cone crusher is a powerful machine that is used in large-scale industries for crushing various types of materials into smaller sizes.
Cone crusher can be used for lots of different projects including road base on construction projects, asphalt pavement resurfacing, or in gravel pits for road construction. Cone crushers are suitable for medium-hard and hard materials – like virgin rock from quarries.
Gyratory Crushers
The walls of the gyratory crusher’s hopper are lined with “V-shaped” pieces, the mantle and the concave, like a jaw crusher but shaped like a cone. The ore is discharged through the smaller bottom output hole of the cone.
While the cone does not move, an interior crushing movement is created by a revolving shaft on a vertical rod. Continuous action is created making it faster than the jaw crusher with less power usage.
Impact Crushers
Impact crushers are often used with materials, which are soft or which are easily cleaving from the surface. The crusher consists of a fast spinning rotor and beaters attached to the rotor.
Impact crusher can also be equipped with a bottom screen, which prevents material leaving the crusher until it is fine enough to pass through the screen. This type of crusher is usually used for soft and non abrasive materials.

Crusher Application
Gold Processing
Metallurgical processing of metalliferous ores in general and gold ores in particular, consists essentially of three stages, often colloquially referred to as: Bashing (crushing); Mashing (grinding); and Hashing (extraction/recovery).
Coal Processing
Coal processing involves crushing, screening and beneficiation.
Beneficiation can improve the quality of contaminated coal that would otherwise be wasted. Most cleaning processes involve washing coal in order to separate coal particles from stone particles.
Platinum Processing
The separation chemistry of the platinum-group metals is among the most complex and challenging of metal separations. Virtually all platinum-group metals are recovered from copper or nickel sulfide minerals, which are concentrated by flotation separation.
Copper Processing
The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica. The second step, involving either smelting or leaching, removes a large proportion of impurity elements. The final step, refining, removes the last traces of the impurity elements and produces a copper product of 99.99 percent purity.
Iron Processing
Iron processing refers to the methods used to extract and process iron from its ores. The primary methods of extracting iron from its ores include: Mining, Transportation, Processing, Ore Beneficiation, Smelting, Refining, Casting and Finishing Processes.
Diamond Processing
Diamond processing is the practice of changing a diamond from a rough stone into a faceted gem. Cutting diamond requires specialized knowledge, tools, equipment, and techniques because of its extreme difficulty. Diamond processing phases: drawing/marking/planning, cleaving/sawing, bruiting and polishing, Final inspection, Recutting.
Chrome Processing
The chromite beneficiation process adopts the combined process of gravity beneficiation-magnetic separation-gravity beneficiation to beneficiate and purify the chromite ore, and the recovery rate and concentrates grade of the beneficiation can meet the ideal requirements. Therefore, it is widely used in the field of chromite beneficiation, and it is a very effective chromite beneficiation process.
Mineral Sands Processing
Various methods which include magnetic, gravity and electrostatic separation as well as chemical processes, are then used to separate the sands into individual mineral species. The ore is put through a screening plant which breaks it down into individual grains.
Industry knowledge
What Is a Crusher?
Crusher Machines are also commonly used for jobs like breaking up asphalt for roadwork or demolition projects.
What Are the Different Kinds of Crushers?
There are lots of different kinds of crushers from jaw crushers to impactors and cone crushers.
Crushing is an versatile process and the kind of crusher you need depends on the ‘stage’ of crushing. The three main stages of crushing are primary, secondary, and tertiary – all of which have their own unique benefits.
Primary crushing involves using a large object as the initial force to break down very large and hard rocks and boulders into smaller pieces before they move onto the secondary stage.
Secondary crushing breaks down materials even further before they go to tertiary level, which makes an even finer product that can then be used in various industrial projects.
What Is the Difference Between a Cone Crusher and Gyratory Crusher?
Gyratory crushers and cone crushers are both types of compression crushers that crush materials by squeezing them between a stationary and a moving piece of manganese hardened steel. There are however some key differences between cone and gyratory crushers.
Firstly, gyratory crushers are designed for crushing very large materials – normally in the primary crushing stage, while cone crushers are typically used for secondary or tertiary crushing to make smaller, finer products.
Secondly, the shape of the crushing head is different. The gyratory crusher has a conical shaped head that gyrates inside a bowl-shaped outer shell, while the cone crusher has a mantle and a stationary concave ring.
