reduction ratio. main application. jaw crushers: soft to very hard: no limit: dry to slightly wet, not sticky: 3/1 to 5/1: heavy mining, quarried materials, sand & gravel, recycling: gyratory crushers: soft to very hard: abrasive: dry to slightly wet, not sticky: 4/1 to 7/1: heavy mining, quarried materials: cone crushers: medium hard to very hard: abrasive: dry or wet, not sticky
“the erc can also crush large hard lumps for example, our erc 25-25 model has a roll diameter of 2500 mm by the width of 2500 mm which can receive large lumps up to 2000 mm x 1500 mm x 1000 mm and crush down to a crushing ratio of 1-6,” kokoroyanis adds. read: thyssenkrupp reduces overall cost s. cost effective mining alternative
taggart expressed the relationship between crusher capacity and reduction ratio in terms of a reduction ton or tonne, qr defined as. (4.22)q r = q t ⋅ r 80. where qt is the capacity in terms of actual tonnage crushed per hour.
for a jaw crusher the thickness of the largest particle should not normally exceed 80–85% of the gape. assuming in this case the largest particle to be crushed is 85% of the gape, then the gape of the crusher should be = 45.7/0.85 = 53.6 cm and for a shape factor of 1.7, the width should be =
tertiary crushing. this is the third stage of crushing. the size, which is around 50–80 mm, of the ore or rock from the secondary crushing process is reduced to between 5 and 12 mm. we call the machine that performs the crushing process a crushing machine or crusher. meka size reduction machines.
