How it works: drum rack-mounted device is tilted. After the drum motor reducer are connected together by coupling means, the drive roller means rotatable about its axis. When the material enters the trommel drum assembly environment, due to the inclination and rotation of the drum assembly, so that the material of the screen surface flip and roll, so that qualified materials (undersize product) by the rear end of the bottom of the drum of the discharge port, unqualified Material (sieve product) by the drum rear exhaust discharge port. As the material within the drum flip, roll, so that the card in the mesh material may be ejected in Shandong drum sieve, sieve to prevent clogging. Drum sieve sand, construction principle drum trommel screening machine with almost the same differences exist and people know it is called. Scope: A large gravel quarry for classifying and separating out the dirt and gravel field with two separate powder and sand three lump coal and the coal industry for the separation and washing (washing machine..... part) IV. chemical industry, mineral industry for grade and size lumps separated powdery substance. trommel mining machine, drum sieve, ceramic plant matter of Building Ceramic plant supplied by Boshan matter. Boshan matter of Building Ceramic plant (www.bsshida.com/) strong, credible, Shandong Zibo crushing grinding equipment industry has accumulated a large number of loyal customers.
