In the mining and aggregates industries, gyratory crushers and cone crushers are two of the most commonly used primary crushers. Every crusher type has its benefits in the production process, but it is often difficult to decide which one to use. The trituradora de mandibula (jaw crusher) is another basic type in these industries, which is applied in various stages of the crushing operation. This paper aims to compare and contrast the gyratory and cone crushers to identify which of the two is more effective in certain operations, and also briefly explain how trituradora de mandibula works in the crushing process.
Gyratory crushers
Gyratory crushers or trituradora giratoria are used for the first stage crushing of run of mine ore in the primary crushing stage. These crushers are characterized by high capacity and large intake of materials, which makes them suitable for handling large quantities of very hard and abrasive materials. Gyratory crushers are characterized by their design that enables them to crush materials between two converging and eccentrically gyrating spindles.
How Cone Crushers Work
Cone crushers are used in secondary, tertiary and quaternary stages of crushing after the initial crushing of the material by gyratory crushers and jaw crusher. These crushers are of a cone shape with a mantle that rotates in a bowl and the rocks are crushed by the action of the mantle compressing them between the mantle and the bowl. Cone crushers are used for crushing hard, abrasive materials and they are more energy efficient than jaw crushers.
Efficiency
In comparing the efficiency of the two crushers, one has to look at the material handling capacity and the size of the material to be crushed. Gyratory crushers are more suitable for handling large amounts of large-sized materials and are therefore more suitable for the initial stage of crushing. On the other hand, cone crushers are more efficient in the secondary crushing stages to produce a more cubical product.
Applicability
The decision of whether to use a gyratory or a cone crusher depends on the hardness and the compressive strength of the rock to be crushed. Gyratory crushers are mainly used for softer and less abrasive materials while cone crushers are used for harder and abrasive materials more effectively.
Cost-Effectiveness and Maintenance
As for the maintenance and operation costs of cone crushers are usually higher than that of gyratory crushers. The operating expenses of cone crushers are also relatively low because of the simplicity of their design and their relatively small size, which also makes them easy to transport and install.
The choice between the two types of crushers is usually based on the characteristics of the material to be crushed and the desired end product. Even though trituradora de mandibula is an essential part of the initial stages of the reduction of materials, the decision between a trituradora giratoria and a cone crusher should be made depending on the efficiency, cost, and the project. Every crusher type has its advantages and is appropriate for certain operations, so it is crucial to understand your project’s needs to select the best crusher.
