石棉选矿,由矿石加工到成品棉分级的整个选别过程中,矿石物料往返联系复杂,而且,除尘系统和工艺系统之间,也有着密切的联系。因此,在复杂的工艺流程系统中,为了便于操作管理,处理事故及时,提高生产效率,常采用集中联锁控制方式。集中联锁控制,可以通过电器接点开关电路的功能,实现设备之间的相互制约。可以通过模拟屏的监视功能,及时判断出设备事故的范围,从而保证流程的正常运转。据我们了解,目前,石棉选矿厂中,集中联锁控制投入运行的还不多。其原因,除了有
Asbestos beneficiation, from ore processing to finished cotton grading the entire sorting process, contact back and forth between the ore material complex, and, between the dust removal system and the process system, also has a close contact. Therefore, in the complex process system, in order to facilitate the operation and management, timely handling of accidents, improve production efficiency, often using a centralized interlock control. Focus on interlocking control, electrical contact switch circuit can function to achieve mutual restraint between devices. Can monitor the function of the simulation screen, timely determine the scope of equipment accidents, so as to ensure the normal operation of the process. According to our understanding, at present, asbestos concentrator, centralized interlocking control put into operation is not much. The reason, except there
