Primary crushers depend for normal operation on the fact that broken rock contains a certain voidage (space between particles). If all the feed goes to a jaw crusher without a preliminary removal of fines, there can be danger of choking when there has been segregation of coarse and fine material in the bin.

Screening the fines before the crusher results in higher overall capacity of the primary crushing stage. High scalping efficiency, more tonnage VG Series™ primary scalpers have been designed for the toughest applications, high capacity and the ability to process abrasive material, either in stationary or mobile crushing plants.
The primary crusher is an important part of the mining process, taking the run of mine (ROM) ore and reducing it to a size which can be processed by the downstream operations.
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-
Laboratory Sample Preparation . 12.2.1.3 Losses Due to Reactions Between Sample and Container Specific elements may be lost from sample materials from interaction with a container.
Primary crushers are suitable for the primary crushing or grinding of clay and minerals coming directly from quarries and for reducing its original irregular size to uniform sizes below 80mm so that the material may be properly batched and stored. Verdés crushers are specially designed to accept non-ferrous minerals that contain moisture ...
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. The factors influencing the selection of a crusher for this service ...

A feeder device such as an apron feeder, conveyor or vibrating grid controls the rate at which this material enters the crusher, and often contains a preliminary screening device which allows smaller material to bypass the crusher itself, thus improving efficiency. Primary crushing reduces the large pieces to a size which can be handled by the ...

A food chain is a network of links in a food web. Here, the producers are consumed by the predators-primary and secondary consumers and then the detritivores and finally by decomposers. When many such individual food chains occur in an ecosystem, it is known as Food Web. A food chain shows a direct transfer of energy between organisms.

The direct, unscreened output from a crusher contains a complete mix of sizes from dust up to the maximum size that the crusher can pass. output from the primary and secondary crushers is fed, unscreened, to intermediate or separate stockpiles. materials drawn from these stockpiles is called crusher run and is used for construction fill.
The primary crusher is a vital part of the extractive process, taking the run of quarry aggregate and reducing it to a size that can be processed by the downstream operations. However, extractive operations frequently have issues related to the primary crusher: low throughput, low utilisation and high wear rate of liners.
The settings on a jaw crusher are designed to produce material ideal for secondary crushing. The best particle shape is typically found in material that is about the same size as the closed-side setting. Smaller sizes will contain a higher proportion of elongated particles because they have passed through the crusher without being touched.
Generally speaking, the large stone first into the coarse crusher (jaw or hammer crushing), which is usually said to be primary crushing. After primary crushing for large stones, then into the fine crusher (impact crusher and cone crusher), that is the secondary crusher. If the size of the stone is up to 30-55mm, then go into the sand-making ...
