磨矿作业是选矿生产中的重要工序。磨机在运转过程中,中空轴轴颈和主轴承轴瓦之间,不可避免地要产生摩擦。为了减少摩擦功耗,降低磨损速度,缓和冲击和控制轴瓦温度,必须保证主轴承有良好的润滑,以提高磨机的工作效率和使用寿命。磨机轴承液压润滑系统是磨机的关键部件,直接影响产品性能和设备安全。为减少基本投资和控制生产成本,磨机存在大型化发展的趋势,这就要求磨机具有更高的可靠性。由于大磨机的负载大,突然断电会使润滑系统的油泵立即停止供油,而磨机由于惯性继续转 Grinding operation is an important process in dressing production. Mill in operation, between the hollow shaft journal and the main bearing pad, inevitably have to produce friction. In order to reduce the friction power consumption, reduce the wear rate, ease the impact and control the bearing temperature, we must ensure that the main bearing has a good lubrication to improve mill work efficiency and service life. Mill bearing hydraulic lubrication system is a key component of the mill, a direct impact on product performance and equipment safety. In order to reduce the basic investment and control the production cost, there is a trend of large-scale mill development, which requires the mill with higher reliability. Due to the large mill load, a sudden power failure will immediately stop the oil pump lubrication system, and the mill continues to rotate due to inertia
