The main function of rotary vibrating screen frame is to fix the screen.

With the different use conditions and screen wire diameter, the corresponding structure of the grid is also different, mainly including:

• The subrack (also known as the male and female slot grid), is welded with the middle frame;

• Subnet grid --separated from the middle frame;

• Grid grid --separated from the middle frame;

• Simple grid --separated from middle frame.

The main net frame of the rotary vibrating screen is fixed with screws, so that the bottom net frame is closely combined with the net frame and fixed on the net frame. The process of this method is complex and suitable for the screening and filtration of main materials. It has a long service life, is not easy to replace, can be repeatedly maintained and used, and plays a supporting and protective role for the subnet. Because of the protection of the main network, the service life of the subnet has been increased by more than 10 times, and the work of replacing the subnet is very convenient, which effectively saves the production time wasted by replacing the network frame.
