A primary impact crusher is a machine that uses striking as opposed to pressure to reduce the size of a material. Primary crushers are used within the first stage of processing and produces higher reduction ratios.

13.3.1.1 Primary Crusher. Primary crushers are heavy-duty rugged machines used to crush ROM ore of (−) 1.5 m size. These large-sized ores are reduced at the primary crushing stage for an output product dimension of 10–20 cm. The common primary crushers are of jaw and gyratory types.
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.
Gyratory crusher is generally used as a primary crusher. The crusher is popular due to its high throughput capacity and the large sized opening. The crusher is well suited for handling direct feed from haul/dump trucks. The gyratory crusher is mainly used in rock that is abrasive and/or has high compressive strength.
The primary impact crushers are used to process from 200 t/h up to 1900 t/h and feed sizes of up to 1830 mm (71") in the largest model. Primary impact crushers are generally used in nonabrasive applications and where the production of fines is not a problem. Of all primary crushers, the impactor is the crusher that gives the best cubical product.

Impact Crushers
The capacity of the primary crusher is generally known, and therefore the process weight of the primary crusher, primary conveyor, and primary screen. After this point, it is frequently not easy to tell what process rates will be. The material processed at the primary crusher and screen will be oversized and undersized.
Crushers are machines that use a rigid surface to compress and break large rocks into smaller rocks, they come in many varieties, such as Jaw crusher, Gyratory crusher, Cone crusher, impact crusher, etc. usually, the choice of a primary breaker is dependent as much on the size of the feed as on the hourly tonnage.
A gyratory crusher is one of the main types of primary crushers in a mine or ore processing plant. Gyratory crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory crushers can be used for primary or secondary crushing.
Primary crushers with crush run-of-mine rock from blast product size to what can be carried by the discharge conveyor or fit/math the downstream process. A typical example of primary crushing is reducing top-size from 900 to 200 mm. In Selecting a primary crusher you need to worry about these requirements:
The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher. The primary crusher converts the feed size to one that is acceptable to the secondary crusher.
ERC –.Jaw crusher is a compression style rock crusher, useful in crushing the medium-hard to very hard material into a smaller particle size at primary crushing stage in the crushing circuit. Applications mining, quarry, construction waste recycling, aggregate making, etc. Materials Limestone, cobblestone, cobblestone, quartz, basalt, iron
A gyratory crusher is one of the main types of primary crushers in a mine or ore processing plant. Gyratory crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory crushers can be used for primary or secondary crushing.
For example, if a horizontal shaft impact crusher is used in primary crushing, the rotor should be solid because the inertia is relatively large, vice versa. How to deal with these damages After the new machine is put into operation, a comprehensive inspection of the impact crusher must be carried out at the end of each shift.
The different types of primary crushers are: jaw crushers, gyratory crushers, impact crushers, and autogenous crushers. By: SBM Group. Nov. 29, 2011
The degree to which material is reduced through stages of primary, secondary, and tertiary crushing can depend on the type of material, like aggregate, concrete, and asphalt, and can also depend on the variety of output sizes needing produced. Primary crushing is the first stage of material reduction and can sometimes be the only stage needed
Gyratory crusher is generally used as a primary crusher. The crusher is popular due to its high throughput capacity and the large sized opening. The crusher is well suited for handling direct feed from haul/dump trucks. The gyratory crusher is mainly used in rock that is abrasive and/or has high compressive strength.
Crushers are divided into two sub-headings in the first stage. they are fixed crushers and mobile crushers. The fixed crushers are divided into 6 categories. These are jaw crusher, primary impact crusher, secondary crusher, tertiary crusher, cubic crusher and vertical shaft crusher. On the other hand, mobile crushers are divided into 4 categories.

The term “primary crusher,” by definition, might embrace any type and size of crushing machine. The term implies that at least two stages of crushing are involved, but in many cases the machine which performs the function of initial crusher is the only crusher in the plant.

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.
Jaw Crusher, also known as concrete crusher, is usually used as the primary equipment for concrete crushing. It is also suitable for metallurgy, mining, construction, chemical, water conservancy and railway sectors, and used as a device for fine and medium crushing of ores and rocks with compressive strength below 250 Mpa.

Jaw crusher is also often referred to as primary crushing. It is the use of two jaw plate extrusion and bending of the material, coarse or medium crushing various hardness of the material. The crushing mechanism of the small jaw crusher is composed of a fixed jaw plate and a movable jaw plate.
Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 32 x 54 Jaw Crusher measures 32" from jaw die to jaw die at the top opening or gape opening and 54” across the width of the two jaw dies. The narrower bottom opening of the crushing chamber is used to size the discharge material.
be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1. The primary operating variable available on a crusher is the set and on jaw and gyratory the open-
