我厂用两台德国进口WF－1065A型辊辗机，分别作粗细物料粉碎用。夏季由于雨水多，辊辗机上粘料太多，刮料板时常刮不干净，从而加重了刮料板的配重，使起动力矩增加，导致电动机起动电流增大。由于此原因，1995年6月份就烧坏30个保险，给生产造成一定损失。为解决上述问题，在 I plant with two German imports WF-1065A-type roller mill, respectively, for the thickness of materials crushed. Summer due to rain, roller too much sticky material, scraper often scraping unclean, thus increasing the scraper weight, so that the starting torque increases, leading to the motor starting current increases. For this reason, 30 insurances were burned in June 1995, causing some losses to the production. In order to solve the above problem,
