某铜矿为扩大再生产,于1997年 1月5日与某市矿机厂签订了一份《购销球磨机、分级机协议书》,规定矿机厂为铜矿制造非标准球磨机一台, 规格为直径4.5米,长6米,同时制造配套分级机一台。设计与制造均由矿机厂负责,总价款为300万元,月底预付货款100万元,余款交货时结清,交货期为4月底,安装调试由矿机厂承担,费用另计,逾期交货,赔偿产值损失。铜矿按期预付100万货款。矿机厂逾期一个月才制造完毕,因无试车台, 未试车即运到铜矿安装调试,铜矿又给付矿机厂103万元。经空负荷和带负荷试车生产,发现球磨机大齿轮圆度和齿距不合格,传动小齿轮严重磨偏,衬套变形严重。分级机纵轴焊接处断裂,下轴头撞击机壳等十几处问题。双方虽有五份整改记要,但矿机厂
A copper mine for the expansion of reproduction, in January 5, 1997 with a city miner signed a “purchase and sale of ball mill, grading machine agreement,” provided for mines for the manufacture of copper mills non-standard one, the specification is Diameter of 4.5 meters, 6 meters long, while supporting the production of a grading machine. Design and manufacture of the mine is responsible for the mine, the total price of 300 million, the end of the advance payment of 100 million, the balance settled delivery, the delivery time for the end of April, the installation commissioning by the miner’s plant, the cost of another Overdue delivery, compensation for output loss. Copper advance payment of 1 million payment on schedule. The mine factory was overdue a month before it was completed, because there was no testbed and no test cars were transported to the copper mines to be installed and debugged. The copper mines also paid the miners 1,030,000 yuan. After the empty load and load test run production, it was found that the ball mill roundness and tooth pitch failed, the drive pinion serious grinding bias, bushing deformation seriously. Classifier longitudinal axis welding fracture, the lower shaft hit the shell more than a dozen issues. Although both sides have five corrections to note, but the miner’s factory
