板石矿业有限公司选矿厂2007年在原厂房中安装了3台美卓HP500型破碎机(1台中碎机,2台细碎机),由于受原厂房条件限制,设备投入使用后,润滑油温偏高,导致油压过低,设备不能正常运行(夏季连续运行5～6 h需要停机2 h,待油温冷却后方可重新启动运行)。HP500型破碎机润滑油冷却系统采用的是风冷散 Slate Stone Mining Co., Ltd. beneficiation plant in 2007 installed in the original plant three Metso HP500-type crusher (1 in the broken machine, 2 crushing machine), due to the constraints of the original plant conditions, the equipment put into use, the lubricating oil temperature side High, resulting in low oil pressure, the device can not be normal operation (summer continuous operation 5 ~ 6 h need to shut down 2 h, until the oil temperature cooling before restarting operation). HP500 crusher lubricating oil cooling system uses air-cooled powder
