一、序言作者根据不同性质的原煤对无活塞跳汰机的操作进行了调整并作了性能试验。由于原煤性质不同,无活塞跳汰机的选分能力也就不同,选分精度偏差也很大。对于原煤性质和选分精度的关系虽有很好的研究和报告,但原煤性质、选分精度和操作条件三者关系并不明确。实际上在设计跳汰机时必须对此三者关系有明确了解。 First, the preamble According to the different nature of the coal without piston jig operation was adjusted and made a performance test. Due to the different nature of coal, no piston jig sorting ability is different, the election accuracy deviation is also great. Although there is a good research and report on the relationship between the nature of raw coal and the accuracy of sorting, the relationship between coal quality, sorting accuracy and operating conditions is not clear. In fact, the design of the jig must have a clear understanding of the relationship between the three.
