Roller frame is an important part of belt conveyor and is used to support rollers and roller sets.According to the types,the frames are divided into two types:Liner frame and offsets frame. 
Roller frames are designed to provide a minimum gap between rollers,and give added protection to the conveyor belt.Frame outer slopers are designed to prevent material build up around the shell end thereby avoiding premature shell wear due to roll jamming. 
The related parameters for the frame: 
1.        The material is Q235(Chinese Standard) equal to ST37(Din standard) 
2.        The thinkness of the steel is 4mm-10mm 
3.        Welding:Mixed gas shielded arc welding 
Our conveyor frames are in accordance with ISO and GB standards and have r eceived CE and ISO certifications. 
Meanwhile all frames are in accordance with ISO and GB standards and have received CE and ISO certifications. 
Selected frames are removed from the productions run at intervals and subjected to full dimension checks and weld quality inspection.
