Primary Crushing - Mineral Processing & Metallurgy
Primary Crushing. 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.
Crushers and Their Types – IspatGuru
Apr 03, 2015 · Crushers are classified into three types based upon the stage of crushing they accomplish. These are (i) primary crusher, (ii) secondary crusher, and (iii) tertiary crusher. The primary crusher receives material directly from run of mine (ROM) after blasting and produces the first reduction in size.
Primary Crusher Selection & Design
How you select your primary crusher will be based on factors like moisture content, maximum rock lump size, material density SG, abrasion index, degradability and it being prone to dusting or not. The crusher capacities given by manufacturers are typically in tons of 2,000 lbs. and are based on crushing limestone weighing loose about 2,700 lbs. per yard3 and having a specific gravity of 2.6.
What is primary crusher and types of primary crushers ...
Raw material, of various sizes, is brought to the primary crusher by rear-dump haul units, or carried by a wheel front-end loader. Primary crushing reduces this run-of-mine rock to a more manageable size. The different types of primary crushers are: jaw crushers, gyratory crushers, impact crushers, and autogenous crushers. Jaw Crusher
Types of Crushers
Pressure crushers, for example, may be divided into two subclasses: the reciprocating, and the continuous-pressure, types. The gyratory and jaw crushers come under the first category, the crushing rolls under the second.
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 because any type and size might …

Primary crusher is only for the breaking of large stones into pieces (this mean primary crusher is not for the aggregate size material.). Examples of primary crushers are jaw crusher; hammer mill crusher and gyratory crusher. After receiving primary crusher crush the material and produce a new fresh reduce size of the source material.
Crushing in Mineral Processing
In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
