| The scraper device 20MG20.11.07.01 of the coal mill is an important part of the coal mill. Its main function is to discharge the stone coal (coal slag produced during the coal grinding process) inside the coal mill out of the side body of the coal mill. The scraper device 20MG20.11.07.01 is usually composed of a scraper seat, a scraper shaft, a scraper, and a torsion spring. The scraper seat is fixed to the bottom of the grinding disc of the coal mill, the scraper shaft is fixedly installed on the scraper seat, the scraper is rotatably installed on the scraper shaft, and the torsion spring is installed on the scraper shaft and connected to the scraper to provide torque for the scraper. The scraper device 20MG20.11.07.01 rotates with the grinding disc of the coal mill, and uses the scraper to droop under the action of its own gravity to sweep and scrape the stone coal, pushing the stone coal forward until it falls into the discharge port. When the stone coal pile increases, the scraper will be lifted up by the stone coal pile and can only be lifted backward. In the process of cleaning and scraping, more stone coal will be left behind and cannot be cleaned to the discharge port. |
