size of primary crushed ore
Crushing involves reducing the ore size from various sizes ranging from particles as big as a human body, or just the size of your head or toe to an average 90 to 140mm for primary crushing or 40 to 55mm for secondary.
Size Of Primary Crushed Ore
Since they take the primary crushed ore as feed, the maximum feed size will normally be less than 15 cm in diameter and, because most of the harmful constituents in the ore, such as tramp metal, wood, clays, and slimes have already been removed, it is much easier to handle.
Primary Crusher - an overview | ScienceDirect Topics
Pyrite ore was crushed by the help of primary crushers involving jaw and cone crushers up to a size of 0.5–2 cm. b. The particles were further grinded by ball and rod milling to the size of 50–100 lm.

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 Crusher Selection & Design
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: That crusher must be capable to reduce the size of even the lastest rocks it is fed.
Crushing in Mineral Processing
Since there are not that many small SAG mill operations of under 2000 TPD, and most sub-2000 TPD mills are built with rod mills and/or ball mills only; the upstream crusher plant needs to have sufficient crushing power to provide a P80 to grinding of typically <1.5″ (40 mm) and often as finely crushed as <3/8″ (9 mm).
Rock Crushing Rule of Thumb - Mineral Processing & Metallurgy
The addition of secondary crushing to an existing circuit are that: Reducing the F80 (80% of the feed size) to the SAG mill by 10mm will result in a 3-6% increase in SAG mill throughput, with the magnitude depending on the ore characteristics and the mill operating conditions; Source Ausenco
(PDF) SIZE REDUCTION BY CRUSHING METHODS
Crushing is the first step of mineral processing where the ore/rocks from the mine site is fed into the mechanical equipment in order to reduce the size of masses for subsequent usage by ...
Secondary Crushing Equipment
The term “secondary crushing” has become well established and familiar through long usage; it applies to the crushing stage, either single or multiple, which follows immediately after the primary crusher, taking all or a portion of the product of the primary crushing stage as its feed. The term should not be used, as it sometimes is, to designate a particular type or size of crusher ...
Asphalt - Crush + Size
In order to achieve such a result, a primary crusher crushes the asphalt to be extracted to a size of < 100 mm in a primary crushing step. In order to be able to even cope with bulky chunk sizes and large edge lengths the crushing tool was manufactured in a way that direct draw-in of the feed material by means of large digging teeth is ensured.

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.
Mineral processing | metallurgy | Britannica
In the primary stage, the devices used are mostly jaw crushers with openings as wide as two metres. These crush the ore to less than 150 millimetres, which is a suitable size to serve as feed for the secondary crushing stage. In this stage, the ore is crushed …
