M AZIZ – CPL300S 97 Lecture 9 PRIMARY CRUSHERS As we have seen before, crushing can be split into two sub classes primary and secondary. Some times there is also tertiary crushing but this is unusual and will not be covered here. We now look at some primary crushers. Primary crushers are heavyduty machines, used to reduce the runofmine ore down to a size suitable for transport and ...

 · The runofmine ore was crushed in a McCully gyratory crusher, two standard cone secondary crushers and oversize recrushed in a shorthead tertiary crusher before feeding to the fine ore bins. From the bins the ore was fed into four Hardinge ball mills, with secondary grinding by Ruwolt tube mills.

Cone crusher and gyratory crusher work on the same principle. Both have the same operation. If cone crusher differs then it is only from crushing chamber. Cone crusher has a less steep crushing chamber and more parallel zone between crushing zones. It breaks the rocks by squeezing it between the gyrating spindles.

 · The gold ore sample of 200 kg was first fed to the primary crusher (PEX150 × 250 mm) and secondary crusher (XPC60 × 100 mm) to ensure all the sample could pass through a sieve of 20 mm. The comminuted ore was then thoroughly mixed and divided, fed to the singletoggle jaw crusher (PEF60 × 100 mm) and HPGR (CLM100 × 250 mm, with applied pressure of N/mm 2 ) respectively.

 · Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size. Both open and closed circuit crushing is .

mines, it is weighed and the ore is sampled for moisture. The moisture determined from the ore in the trucks is used as the basis to calculate the number of dry tons of ore for metallurgical accounting. Each mine's ore is kept separate in lots for control purposes through crushing and sampling. Lots vary from 200 to 2000 tons each.
