Method for adjusting gap between screening basket and scraper of mining centrifugal machine

The invention discloses a method for adjusting the gap between a screening basket and a scraper of a mining centrifugal machine. The method comprises the following steps that a scraper gasket is usedfor cushioning the scraper of the centrifugal machine to be high, and the scraper is located on the top of the screening basket; a plurality of screening basket gaskets are additionally arranged on ascreening basket base, and it is guaranteed that the gap between the scraper and the screening basket is within 1-3 mm; when the scraper is abraded, the height of the screening basket is reduced by reducing the number of the screening basket gaskets on the screening basket base; and through running, it is ensured that the gap between the scraper and the screening basket is within 1-3 mm, and the content of water in commercial coal reaches the standard. By means of the method, the water content in the commercial coal is reduced to 5%-10% from 16%-17%, and the original gap adjusting time which is 36 h is shortened to 1.5
