All types of crushers are widely used in gravel and aggregate fields, and they are often put in use after the excavation and blasting processes. Although their common and basic function is reducing large size of rock into small size, they are applied to different crushing stages like primary, secondary, tertiary, quaternary stages.
Our crushers have been designed to fullfill the various requirements of stone quarries, mining facilities and industrial facilities. We offer a variety of sizes and styles in three different crushing groups—primary, secondary and tertiary—which are used to crush materials with dimensions up to 1000mm and vary depending on capacity, hardness and …
Impact crushers can be used as primary crushers, secondary crushers or tertiary crushers depending on the size and technology. They are equipped with beaters, also called hammers, and impact plates. They operate in the following way: they are fed from the upper part, then the stones are hit by the hammers and projected towards the plates.
Primary crusher is the workhorse that takes blast feed sizes and turns them into smaller sizes that are manageable for other site components—the belts, the screens, and eventually any secondary crushers—on the road to a finished product. All components at a crushing site depend on the primary crusher functioning properly, which is why ...

For some time, as was quite logical, the remedy consisted of installing more small secondary crushers, generally small gyratories. This procedure assumed rather startling proportions in some large plants. For example, the array of crushers in the plant comprised one 48″ primary, four No. 7.5 secondaries and a battery of finishing crushers ...
During the same years wherein the industry was concerned with development of larger and still larger primary crushers,another member of the family was born: the single, sledging- roll crusher. The Allis-Chalmers Co. entered this field in 1911, building two sets of 36″ dia. x 60″ face single-roll crushers, flux limestone plant.
Primary HSI crushers are considerably wider than primary breakers at comparable capacity ratings. Secondary horizontal-shaft impact (HSI) crushers These crushers are characterized by a high 10:1 reduction ratio and by their suitability for generating a cubical product.
The right one for primary crushing often depends on the material to be crushed, but the reduction ratio of jaw crushers are usually between 8:1 and 6:1. Secondary Crusher. These crushers break down materials into smaller sizes and often have a reduction ratio less than 3:1 in crushing. A secondary impactor, hammermill, and cone crusher are ...
Primary crushing operations takes boulder size feeds (20 to 100 inches) and reduces the material to secondary crusher feed size (1 to 20 inches) or mill feed size (0.5 to 3 inches). This video illustrates single- and double-toggle jaw crushers. ... Jaw crushers feed materials between fixed and reciprocating plates. Blake, swing, overhead ...

Impact crushers can be used as primary crushers, secondary crushers or tertiary crushers depending on the size and technology. They are equipped with beaters, also called hammers, and impact plates. They operate in the following way: they are fed from the upper part, then the stones are hit by the hammers and projected towards the plates.
HSI crushers can be primary or secondary crushers. In the primary stage, HSIs are better suited for softer rock, such as limestone, and less abrasive stone. In the secondary stage, the HSI can process more abrasive and harder stone. CONE CRUSHER. Cone crushers are similar to gyratory crushers in that they have a mantle that rotates …

Blake jaw crushers, also as double toggle jaw crushers, are characterized by the position of the pivot of the swing jaw, which is located at the top of the machine. This design allows for a larger feed size and a higher capacity, making it suitable for primary crushing. The motion of the swing jaw in a Blake crusher is predominantly vertical ...
Secondary crushers use the same size bottom shells as certain size primary crushers, but different size top shells, mainshaft and spider assemblies. The 30-70 secondary gyratory crusher uses the bottom shell of the 42-65 primary crusher; the 24-60 secondary uses the 30-55 primary bottom shell.
L&T Roll Crushers are rugged in design and used in Primary and Secondary crushing for various mineral application. These crushers are widely used due to compact size, high capacity, low power requirement, …

The gyratory crushers crush to reduce the size by a maximum of about one-tenth its size. Usually, metallurgical operations require greater size reduction; hence, the products from the primary crushers are conveyed to secondary or cone crushers where further reduction in size takes place. Here, the maximum reduction ratio is about 8:1.

They are typically used in the primary reduction of material to provide a smaller material for secondary or tertiary sizing. Feeder-Breakers are one of the best machines for low fines generation. Most crushers, especially compression crushers, are great for handling materials that are hard and abrasive, but not sticky.
Primary crushing reduces the material to a size that secondary or tertiary crushers can further process. In some cases, it may also be necessary to use rock breakers to reduce the size of the material even further. …
The primary can produce these sizes at a rate of 150 to 12 000 mtph depending on the feed characteristics of the ore, the crusher setting, crusher size and the connected power to the crusher.

Cone crushers are fed with pre-screened material from the primary crusher (usually a jaw crusher or primary gyratory), and the secondary crusher should always, if possible, have a scalped feed. Ideally, the deck on the scalping screen should have a cut point equal to the closed side setting (CSS) of the crusher.
