当前，为了提高洗煤企业的生产能力，需要一些能提高产量，性能可靠的新设备，建设新的洗煤厂时，也需要用新的科技含量高的设备，取代过去的旧机型，以达到提高经济效益的目的。过去，洗煤厂大量采用LL3-9离心脱水机．由于该种产品产量低，不便于维修，润滑系统容易出故障，外 At present, in order to improve the production capacity of coal washing enterprises, some new equipment that can increase the output and reliable performance is needed. When building a new coal washing plant, new high-tech equipment will also be needed to replace the old ones in the past to achieve improvement The purpose of economic benefits. In the past, coal washing plants extensive use of LL3-9 centrifugal dehydrator. Due to the low output of this kind of product, inconvenient to repair, the lubricating system is prone to failure
