Sealing of roller holes in roller kiln

Roller kilns all need sticks to drive. Then: in order to allow the sticks to rotate naturally and flexibly, they are not caught by the hole bricks on both sides of the kiln. There is a certain gap between the rollers and the roller holes on the hole bricks. It is 10-20mm larger than the outside diameter of the stick. In order to prevent the hot air from going out of the kiln and cold air entering the kiln, which affects the temperature control and temperature uniformity, it is necessary to pay attention to the degree of sealing of the roller holes.

Electric roller kiln

Modern industrial roller kiln adopts ceramic cotton filling method to seal the roller holes, that is, the hole bricks with a thickness smaller than the thickness of the kiln wall are used to make the hole bricks leave a certain thickness of kiln wall space. The roller kiln is installed well. After sticking, this space is filled with ceramic wool. In this way, the sealing method is simple and effective. It not only allows the sticks to rotate flexibly, but also plays a sealing role. At the same time, it also strengthens the heat preservation effect here. Therefore, it has been widely used by roller kiln manufacturers.
