    摘要： Jacks are positioned about the base of a coal pulverizing bowl mill to elevate the separator housing which contains and supports the journal rolls. The separator housing is raised by the rollers attached to the jacks. Once raised, the housing is rotated to sequentially position the access door of each journal roll to the front of the mill. A mobile crane conveyance is stationed at the front of the mill to remove and replace each journal roll through its access door.

    摘要翻译： 千斤顶围绕煤粉碎碾磨机的底部定位，以提升包含并支撑轴颈辊的分离器壳体。 分离器壳体由连接到千斤顶的滚轮升高。 一旦升起，壳体被旋转以顺序地将每个轴颈辊的进入门定位到轧机的前部。 移动式起重机运输工具驻留在轧机的前部，以通过其检修门移除和更换每个轴颈辊。
