Primary crushing is the first Occasionally, a Jaw Crusher may be applied as a secondary crusher. Cone Crushers. Cone Crushers are compression whether it be material reduction for further handling downstream or final product sizing. Selecting the right crusher for each stage of the crushing process depends on an The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m.

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 crushing action, and wide crushing stroke. Outstanding gradation control and cubical product also make the R450 an excellent tertiary crusherToday, primary crushing is viewed as more important within the balance of production and proper sizing needs. The size and type of the primary crusher should be coordinated with the type of stone, drilling and blasting patterns, and the size of the loading machine. Most operations will use a gyratory, jaw or impact crusher for primary crushing.P&Q University Lesson 7: Crushing & Secondary Breaking

Evaluation of blast fragmentation effects on jaw crusher
In the aggregate industry, for tonnage outputs less than 1000 metric tons per hour, jaw crushers are the dominant type of primary crusher. Jaw crushers All jaw crushers are distinguished by the presence of two plates, one of which is fixed and one that swings open and then closes, concurrently trapping and crushing material between the The Jaw Crusher was first introduced by Eli Whitney Blake in 1858 as a double-toggle Jaw Crusher. Introduced in 1906, McLanahan’s Universal Jaw Crusher was one of the first modern era overhead eccentric Jaw Crushers. On the overhead eccentric style Jaw Crusher, the moving swing jaw is suspended on the eccentric shaft with heavy-duty McLanahan Jaw Crushers

Particle size distribution curves of recycled aggregates from building demolition concrete crushed by jaw and impact crushers. The jaw crusher produced 60% of coarse aggregates in weight, whereas the impact crusher produced 49% coarse aggregates. The proportion of particles finer than 0.15 mm is around 7–8% weight for The 159 indicates a 548 crusher size with 1″ eccentric throw. With 1-in. eccentric throw, the motor hp allowed on the crusher is a maximum of 125.
