Production capacity
1. First introduce the gyratory crusher. When calculating the production capacity of the gyratory crusher, the volume of the ore discharged when the moving cone is rotated one week is approximated as a ring-shaped annular body. The actual calculation can be based on the following empirical formula: Q=K1.K2.K3. Q0, Q is the crushing machine production capacity under production conditions, t/h; Q0 is the crushing machine production capacity under standard conditions (medium hard ore, bulk density 1.6t/m3) open circuit crushing, t/h; K1 is The friability coefficient of the material; K2 is the material bulk density correction coefficient; K3 is the feed particle size correction coefficient.
2. For the medium and fine crushing cone crusher, it can be calculated according to the following empirical formula: when the open circuit is broken, the production capacity of the medium and fine crushing spring cone crusher is the same as that of the rotary crusher. The difference is that K1 can refer to the given table. K3 is the correction factor for the crush ratio. When the closed circuit is broken, there are: Q closed = KQ open, K is the coefficient of the average feeding size when the closed circuit is narrowed, and the intermediate or short head type cone crusher is generally selected according to 1.15~1.40 when the closed circuit is used. When the value is soft, Q is the production capacity of the crusher when the circuit is open, t/h.
3.The production capacity of single-cylinder hydraulic cone crusher: Q=q0.e.δ/1.6, t/h where q0 is the production capacity per unit width of the miner's discharge port, t/h·mm, can be obtained by looking up the table. ;e is the width of the discharge port of the crusher, (mm); δ is the bulk density of the ore, (t/m3).
Motor Power
1. The motor power of the gyratory crusher can be calculated according to the following empirical formula: N=85D2K, (KW), where D is the diameter of the lower part of the moving cone, m; K is the correction coefficient of the number of revolutions of the moving cone, which can be obtained by looking up the table.
2.The motor power of the medium and fine crusher cone crusher is calculated according to the following empirical formula: N=50D2.
3.Single cylinder hydraulic cone crusher motor power: N = 75D1.7.
However, the calculated motor power of the cone crusher is generally 2 to 3 times greater than the crusher power during normal operation to ensure peak load at start-up and when falling into non-broken objects.
