60年代初得到工业应用的磨机橡胶衬板,在二次磨矿作业中,从磨损成本方面看曾具有竞争力;虽然其成本较钢衬板高,但磨损寿命要比钢衬板长。但是,在粗磨机中,就磨损成本比或单以寿命计算,橡胶衬板并无竞争力。现在,成本情况已发生变化,在某些应用场合这种变化对橡胶衬板有利;按处理量计,橡胶衬板的成本可以降低1/3～1/2。此外,为了适应一次磨机中常见的恶劣磨损条件,已研制出一些新品种橡胶。然而,用于所有磨机中的橡胶衬板磨损寿命仍不够长。在一次磨机中,尤其在自磨(AG)和半自磨(SAG)磨机中,使用较厚的橡胶件可以补偿较高的磨损率,而且对磨机处理量无不利影响。但在十分恶劣的应用条件下,橡胶
Mill rubber liners for industrial applications in the early 1960s were competitive in terms of wear costs in secondary grinding operations; although they cost more than steel liners, they had a longer wear life than steel liners. However, in roughing machines, rubber linings are not competitive in terms of wear cost or life-cycle alone. Costs have now changed, and in some applications this change is good for rubber linings; the cost of rubber linings can be reduced by a third to one half on a throughput basis. In addition, a number of new varieties of rubber have been developed to accommodate the harsh wear conditions commonly found in one mill. However, the wear life of rubber liners used in all mills is not long enough. In one mill, especially in self-abrasive (AG) and semi-autogenous (SAG) mills, the use of thicker rubber parts compensates for higher wear rates without adversely affecting mill throughput. But under very bad application conditions, rubber
