Run of Mine (ROM) materials are brought directly from blasting projects and crushed a primary crusher for the first round of crushing. At this point, the material receives its first reduction in size from its raw state. Primary crushing produces materials ranging from 50" to 20" on average. The two main types of primary crushers are: Jaw crushers

The Raymond grinding mill, Raymond mill for short, is a roller mill in which the central spindle drives the multiple grinding rollers installed on the plum-blossom rack to swing outwardly under the action of centrifugal force and press the grinding ring on the inner wall of the casing to grind the material.
The drive is assembled on a base frame, which is connected with the roll crusher. The floating roll drive, also supported in pivoting mode, is connected with the floating roll rocker arm by a coupling rod. This ensures that a constant drive belt tension exists during the retraction movement of the floating roll, and during gap adjustment.

The speed of rotation of the mill. At low speeds of rotation, the balls simply roll over one another and little crushing action is obtained. At slightly higher speeds, the balls are projected short distances across the mill, and at still higher speeds they are thrown greater distances and considerable wear of the lining of the mill takes place.

Jaw crushers are the most common primary crushers used in the mining and construction industry. They are represented by a fixed jaw and a moving jaw that form a V-shaped crushing chamber. The moving jaw moves back and forth and presses the material against the fixed jaw, that in turn causes it to break down into smaller pieces.
In summary, and relative to an SAG mill primary circuit, HPGRs appear to be most attractive with hard and abrasive ores, and in environments with high power costs. Availabilities are now such that aside from rolls change-outs, which are akin to a mill liner change, the unit rarely controls circuit availability.
