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. The factors influencing the selection of a crusher for this service are much the same, regardless of how many crushing stages there are in the flowsheet; therefore, the term “primary crusher,

2.1 The primary crusher. The primary crusher is located in the quarry and consists of a McLanahan 48″x72′ Shale King Crusher rated at 1,000 TPH (Tons Per Hour). The driving flywheel has a diameter of 2.5 meters and is motor driven through six v-belts. The capacity of the primary crusher had to be increased to 1,250 TPH to produce enough material to serve the wet and both dry lines in the plant.

Primary Crusher The first crusher in a crushing system into which material is fed. Succeeding crushers in the system are referred to as secondary (second), tertiary (third) or quaternary (fourth) crushers. Reduction Ratio The ratio of the top size of input material to the top size of crusher discharge material. Run of Mine (ROM)

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.

Optimizing Crusher Control E & MJ

In a CG-type primary gyratory, if a big rock becomes jammed in the crusher intake, the ASRi system allows the operator to switch from “automatic” to “manual” mode so that the crusher can be opened. This might help to re-orientate the rock sufficiently to enable it to be crushed. The ASRi is then switched back to “automatic” and the crusher returns to normal operating conditions
