Feed particle size = 6 25 mm. Peripheral speed = 85 146 m/min (280 480ft/m in) Reduction ratio = 2 20 depending on material. Typically R = 8.
WhatsApp: +86 182036953773. Different grinding medium. The Rod mill usually uses the steel rod with a diameter of 50100mm as the grinding medium, while the ball mill usually uses the steel ball as the grinding medium. The steel balls of ball mill are in point contact, while the steel rods of Rod mill are in linear contact, so their working ways are obviously different.
WhatsApp: +86 18203695377A series of comminution tests was carried out to evaluate three multipass HPGR circuits and a jaw crusherball mill circuit. Combinations of HPGR units ( m and m diameter), jaw crushers and Bond ball mills were used to grind a 32 mm top size porphyry copper feed (BBWI = ) to a product P80 size of about 150 µm.
WhatsApp: +86 18203695377The reason why rod mill is called rod mill is that its grinding medium is steel rod, while the grinding medium of ball grinding mill is steel ball. Because the shape of the grinding media is different, the working mode has its own characteristics. When the steel rod is in motion, the gap between the rods is a regular long strip, which plays a ...

WhatsApp: +86 18203695377Rod mill changes the surface contact of traditional ball mill to line contact. When the rod rotates and rises along with the liner, the coarse particles are sandwiched between them, allowing the fine particles to pass through the gap of rods, which is conducive to crushing coarse particles, so the coarse particles are concentrated in the place ...
WhatsApp: +86 18203695377Since there are not that many small SAG mill operations of under 2000 TPD, and most sub2000 TPD mills are built with rod mills and/or ball mills only; the upstream crusher plant needs to have sufficient crushing power to provide a P80 to grinding of typically <″ (40 mm) and often as finely crushed as <3/8″ (9 mm).
