在许多矿山,特别是在北方的露天矿山。磨矿矿浆的温度会随季节的变化而显著变化。本文表明,在冬季如果不调节温度,温度的变化就会引起自磨效率损失多达20％。实验室研究证明,这种影响是由于温度降低导致矿浆粘度增大所致。另外,冻结矿石的强度变化也可能产生影响。其可能的机理本文亦予以讨论。然而,还没有最终证明真正因矿石强度的变化而引起的影响。 In many mines, especially in northern opencast mines. The temperature of the ground ore slurry changes significantly with the seasons. This paper shows that if the temperature is not adjusted in winter, the temperature change will cause the loss of self-grinding efficiency up to 20%. Laboratory studies have shown that this effect is due to the temperature decreases lead to increased viscosity of the pulp. In addition, changes in strength of frozen ore may also have an impact. Its possible mechanism is also discussed in this article. However, there is no final proof that the real impact of changes in ore strength.
