简介:摘要:球磨机因破碎比大、作业率高、能耗低等特点在节能降耗、优化选别指标等方面具有显著作用,它广泛应用于火力发电、水泥、硅酸盐制品、新型建筑材料、耐火材料、化肥、黑与有色金属选矿以及玻璃陶瓷等生产行业,对各种煤和其它可磨性物料进行干式或湿式粉磨。球磨机作为燃煤发电机组制粉系统中的最主要设备之一,球磨机的运行工况将直接影响到发电机组的运行状况,制粉系统中当球磨机出现问题时,如果不及时处理将给电厂带来巨大的经济损失,球磨机在设备运行过程中轴承振动问题一直较为普遍,在经常性振动的情况下,一方面会导致出力效能显著下降,促使设备的耐久性不断下降,同时还会影响设备的生产负荷量提升,对机组运行造成经济性损失,严重时还会危机设备的安全运行。
简介: 摘要:半自磨机是物料经过破碎之后在进行研磨的关键设备,主要是通过电机带动小齿轮和大齿轮的转动,实现半自磨机的匀速转动,利用磨机筒体内的钢球和物料自身对物料进行研磨。日常使用中,由于多种因素影响,半自磨机的大齿轮齿极易产生断裂,影响半自磨机的正常使用,对物料的破碎效率影响较大。本文将从半自磨机断齿原因出发,具体分析改善半自磨机大齿轮断齿的具体措施。
