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.
Crushing is the first mechanical stage in the process of comminution in which a principal objective is the liberation of the valuable minerals from the gangue. Crushing is typically a dry operation that is performed in two- or three-stages (i.e., primary, secondary, tertiary crushing).
Primary crushing. The duty of the primary crusher is, above all, to make it possible to transport material on a conveyor belt. In most aggregate crushing plants, primary crushing is carried out in a jaw crusher, although a gyratory primary crusher may be used.
Primary Impact Crushers are preferred for their high capacity and reduction ratios in crushing soft and medium hard rocks like limestone, gypsum. Due to their operating principle, reduction ratio is higher than in jaw crushers.
For instance jaw or gyratory crushers in primary crushing and cone crushers in secondary crushing. Primary crushing is for the robust. The very first crushers invented were jaw crushers, which are built to reduce the size of large materials and operate with high volume in primary crushing. Their main purpose is to reduce the material to a small
Primary crushing reduces the large pieces to a size which can be handled by the downstream machinery. Some crushers are mobile and can crush rocks as large as 1.5 meter (60 inches). Primarily used in-pit at the mine face these units are able to move with the large infeed machines (mainly shovels) to increase the tonnage produced.

In general, a rock crushing plant will have a primary crusher, primary screen, secondary crusher(s) and secondary screen(s), and associated conveyors and stockpiles. It may also involve portable generators powered by diesel engines. Emissions of each pollutant must be less than 100 TPY for the facility to be a minor source.

Primary Crushing Mineral Processing & Metallurgy. 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 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:

Primary Crushing Mill. The MSC 4/2 Crushing Mill is designed to crush large pieces of raw material (clay, kaolin, feldspar etc.) having sizes ranging from 500 mm to 600 mm on input and from 60 mm to 75 mm on output. The machine’s main purpose is reducing material size to make it suitable for the next processes of primary milling, dosing
Primary crushing is the first stage of material reduction and can sometimes be the only stage needed to generate the desired product for a job. Depending on the setup, primary crushing will take the larger material that has been blasted, excavated, or reclaimed and process it through an impactor, jaw, or gyratory crusher to generate a range of

And primary crushing means the first time crushig, usually, you can use a jaw crusher or cone crusher for the first crushing. With the characteristics of large crushing rate, well-distributed
Jaw crusher is the traditional crushing equipment with many models and large output. PE jaw crusher is mainly used for primary crushing of various ores and undisturbed materials, also used for both coarse and fine crushing. There are many models of PE jaw crushers, among which the most popular models are PE-750×1060, PE-600×900, PE-150×250, etc.
Crushing is accomplished by compression of the ore against a rigid surface or by impact against a surface in a rigidly constrained motion path. Crushing is usually a dry process and carried out on ROM ore in succession of two or three stages, namely, by (1) primary, (2) secondary, and (3) tertiary crushers.

Primary crushing with jaw crushers In terms of the size of the feed opening, the client gets a better return on investment when the primary crusher is a jaw crusher. That means less drilling and blasting because the crusher accepts larger boulders.

Primary Crushing Training Module. In this training module, Performance Associates International (PAI) covers the characteristics of a gyratory crusher that’s designed to be the first stage in the size reduction of run-of-mine ore. A gyratory crusher receives ore from a mine and crushes the ore between a gyrating main shaft and stationary
crushing is primary operation which is performed with a large size particle while grinding is performed after crushing. In crushing attrition force is applied while … difference between crushing grinding in India – Gold Ore Crusher
Primary crushing brings run-of-mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below “Dry” crushing includes work on ore as mined, which may be somewhat moist when delivered. It is succeeded by comminution in water, arbitrarily called “grinding”.
It is usually employed for primary crushing with a reduction ratio of 6 to 1. Compression – As the name implies, crushing by compression is done between two surfaces, with the work being done by one or both surfaces. Jaw crushers using this method of compression are suitable for reducing extremely hard and abrasive materials.
