In most aggregate crushing plants, primary crushing is carried out in a jaw crusher, although a gyratory primary crusher may be used. If material is easily crushed and not excessively abrasive, an impact breaker could also be …
Closed side setting (CSS) The closed side setting can be calculated by deducting the stroke from the OSS. CSS is the most important crusher parameter since it defines the maximum product size and has significant bearing on capacity, product gradation, power draw, and wear. Nip angle. The nip angle is the angle between the …
The first step in choosing a primary crusher takes place at a high level. It's necessary to identify the purpose the crusher will be used for. This purpose is a given that precedes the entire decision-making process. Sometimes, a measure of guidance or experience is needed. The two main components to consider when identifying purpose are feed ...

JAW CRUSHER. 8:1 maximum reduction ratio for compression crushing, this is normally used as a primary crusher. Jaws perform well in many materials. Yields low wear cost per ton in hard abrasive deposits, minimal fines but produces little finished (under 1") product which places more load on the crushers downstream in the circuit.
The gyratory crushers are equipped with a hydraulic setting adjustment system, which makes it possible to regulate the gradation of the crushed material. Cone crushers . Cone crushers resemble gyratory crushers from technological standpoint, but unlike gyratory crushers, cone crushers are popular in secondary, tertiary, and quaternary crushing ...
Horizontal shaft impactor crushers produce a highly cubical product with enhanced soundness. The gradation is more uniform and can be adjusted by changing the RPM (revolutions per minute) of the rotor. Additional gradation control is provided by adjusting the grates or aprons within the machine.
The top stage of a Triple Roll Crusher has a 6:1 ratio of reduction, whereas the bottom stage has a 4:1. In a triple-roll configuration, the primary stage of crushing occurs in the top stage of the crusher and features a single roll configuration that performs the initial crushing.
The output gradation of the primary HSI crusher is generally coarser than the primary breaker due to the lack of expansion above the rotor, which also affects the capacity. Primary HSI crushers are considerably wider than primary breakers at comparable capacity ratings. Secondary horizontal-shaft impact (HSI) crushers
accept primary-crushed ore from a jaw crusher with greater flexibility (up to 25% larger material) because of its 1.3m (52-inch head) diameter, large feed opening, high-pivot-point ... Outstanding gradation control and cubical product also make the R450 an excellent tertiary crusher for aggregate, asphalt and concrete products. 6. FLS ...
Primary Gyratory Crusher Specifications . Note: 1. Capacity shown is based on an assumed feed distribution which 100 % of feed passes 90% of feed opening and 80% of feed passes 42% of feed opening. 2. Capacity shown is based on continuous feed of typical limestone or similar with a bulk density of 100 lb/ft. 3.
Primary Crusher Product. It was formerly the custom to consider one set of product gradation, or screen analysis, curves as being suitable to represent the products of both primary (unscreened) and secondary feeds, making no allowance for the undersize material which is always present, to some extent, in quarry-run and mine-run materials. …

ULTRAMAX® IMPACTOR MODEL AND SPECIFICATIONS* » Designed for stationary, skid or portable mounting in a primary/secondary application, or for a …
The two main components to consider when identifying purpose are feed size and type of material to be crushed. There are a variety of other factors to review as well—the long-term strategy for the site, discharge gradation, moisture content of the material, and the targeted amount of production, just to name a few.
determine real time crusher feed and product gradations as well as down stream size analysis. Feed to the primary crusher from the mine can be measured and monitored to establish blasting performance required to obtain high crusher utilisation when bucket size is …
Similar to Sizers, Roll Crusherscan be used for the primary crushing of soft to medium hard material that can be slightly abrasive, dry, or wet and sticky. They are typically used in heavy mining applications and have a typical ratio of reduction of 4:1. Primary Roll Crushers are available in …
