Abstract The high-pressure grinding roll (HPGR) is a type of roller mill that continuously produces particle-bed comminution. Since the capacity of the HPGR is determined by not only operating conditions but also the roll geometry, knowledge of the effectiveness of the roll geometry is still limited. This study investigated the effect of the stud diameter on the capacity of a stud-type HPGR ...
When the roll diameter reduces to less than the minimum diameter required by the mill stand after turning down, then the roll is to be discarded. Stand and roll guide set-up The goal of mill and the roll guide setup is to get the first bar rolled when changing product, on the cooling bed within the tolerance so that it is a saleable product.

The effect of roll length and roll diameter on capacity (throughput at a given level of performance) is of interest because the size of the rollers strongly influences the installed cost of a mill. The effect of roll diameter on the capacity of a mill is not well established. It is complicated by...
Roll diameter is in the order of 25 cm. Roll length depends on the capacity. Two or three pairs of rolls are provided, mounted one on top of the other. A vibrating conveyor secures feeding of the mill at a uniform rate. The corrugations on the upper pair of rolls …
The effect of the stud diameter on capacity was investigated and evaluated. • A smaller stud produced a larger working roll gap during HPGR grinding. • The stud diameter had less effect on throughout and power during HPGR grinding. • The DEM with a breakage model is an effective tool for the roll design of the HPGR.

The effect of roll diameter on mill capacity. The effect of roll diameter on the capacity of a mill is not well established. It is complicated by a likely interaction with mill speed. A rudimentary, theoretical approach is used to advance the thesis that mill capacity is fundamentally proportional to the diameter of the mill rolls.
the effect of roll diameter on mill capacity. The front roll is smaller in diameter as compared to the back roll. And hence when you see a refiner mill identified as 21″ x 24″ x 36″, you simply need to decode it as Front Roll diameter is 21 inches, Rear Roll diameter is 24 inches and both the rolls have same face length of 36 inches.
