我矿新建日处理量2000吨矿石的选厂,选矿流程分为粗选、重选和精选三个工段。粗选工段破碎矿石是用两台PYB—1200标准型和PYD—1750短头型圆锥破碎机。这两台设备是选厂选矿流程的咽喉。 PYB—1200标准型和PYD—1750短头型圆锥破碎机安装后经试车检查,验收合格后投入生产,开始运行良好,破碎矿石效率较高。但使用到8个月以后,便不断出现各种故障。首先齿轮润滑油泵滚针轴承被烧坏,我们改用滚珠轴承,以增大负荷能力。但使用不久,又被烧坏。于是多次更换油泵轴承。接着传动轴
I mine new processing capacity of 2,000 tons of ore dressing plant, beneficiation process is divided into roughing, re-election and selection of three sections. Rough cut section of the ore is broken with two PYB-1200 standard and PYD-1750 short head cone crusher. These two devices are the throat of the beneficiation process. PYB-1200 standard and PYD-1750 short head cone crusher after installation by the test car inspection, after passing the test into production, began to run well, broken ore higher efficiency. However, the use of the 8 months later, they continue to appear a variety of failures. First gear oil pump needle roller bearings are burned, we use ball bearings to increase load capacity. But soon after use, it was burnt again. So many times to replace the pump bearings. Follow the drive shaft
