焦家金矿原有洗矿筛分设备所用的上层筛板为普通圆钢焊制，下层为钢编金属筛网，使用寿命短，筛分效率低，更换频繁，检修不便，噪音高。1997年6月引进耐纳特耐磨弹性橡胶筛网，应用结果表明该耐磨弹性筛网的磨损率很低，还具有耐氧化和耐腐蚀的性能，比普通圆钢焊接筛网成本下 Jiaojia Gold mine screening equipment used in the original screen sieve for the ordinary round steel welding, the lower layer of steel woven metal mesh, short life, low screening efficiency, frequent replacement, maintenance inconvenience, high noise. In June 1997, the introduction of Nepalese wear-resistant elastic rubber screen, the application results show that the wear-resistant elastic screen wear rate is very low, but also has oxidation and corrosion resistance than ordinary round steel welding screen costs
