The capacity of an HPGR circuit, as distinct from the unit capacity discussed above, is obviously a function of the circuit design. Of the above variables, the feed bottom size is particularly relevant in this regard, as a truncated feed necessarily implies the pres- ence of a screen or other classification device upstream of the HPGR.

The HPGR was found to have applied 1.3 mm material as opposed to the cone crusher that produced 5. which is still significant. based on the plant trails.0 0.69 :1 (HPGR: Cone) However the HPGR was found to have generated 60.51: 1 implying that the HPGR is 2.1 0.289 kWh/t.335 / 0. while the cone crusher applied 0.3 mm size material.
With a HPGR system, it is imperative that the cone crushers and vibrating screens are of adequate capacity and durability. For this reason, plant designers have preferred single stages of both crushing and screening and the vibrating screen operates as both a coarse scalping screen and a sizing screen.

In this chapter, these two types of roll crushers are described. 6.2. ... Capacity of Roll Crushers. ... The production capacity of HPGR can be taken as the volume of material passing through the gap between two rolls. It therefore depends on the width of the rolls, the working gap and the velocity of material through the gap. ...
High Pressure Grinding Rolls (HPGR) HPGRs are modern and efficient comminution machines, which are becoming more and more popular in mineral processing. In addition to the industry-leading equipment that TAKRAF already offers to the mining industry, the TAKRAF HPGR is a benchmark in further developed comminution technology

Triple Roll Crushers combine a Single Roll Crusher with a Double Roll Crusher to form a crusher that is capable of achieving a 6:1 reduction ratio in the primary stage and a 4:1 reduction in the secondary stage while producing a cubicle product at high capacity.
The maximum feed size for pilot scale HPGR testing is 32 mm so the entire lot was further crushed below this size using a 32 mm screen in closed circuit with a jaw crusher. A smaller portion of the resulting feed, about 500 kg, was then crushed below 10 mm for bench-scale HPGR testing.
