三、Manufacturing Standards & Technical Requirements
  1、Main part of roller is 42CrMo, normalizing hot treatment could gain the hardness of HB220-260, surface of main shaft bead welded with anti-friction material and main shaft takes use cooling water for cool.
2、Bracket structure composes of up & down beams and left & right columns, bearing pin and high strength bolt connect to be a whole frame welding structure and material of main bracket are Q235 steel plate. 
3、After welding the main bracket should eliminate stress relieved treatment for the whole bracket.
4、In order to ensure safe and stable operation of roller mill, lower surface abrasion of roller, better extruding effect, we should prevent the steel alloy and other foreign bodies from entering.
5、The thermocouple is equipped with main bearding for monitoring the temperature of bearing.
6、Main bearings of roller should be treated by normalizing and made the flaw detection by ultrasound.
7、Painting of roller mill should be even with same tone and there is no flowing or drop hanging appearance.
8、Control cabinet of roller mill could equip with centralized control connector and the control cabinet PLC is manufactured by Siemens.
9、Base of extruder could accord with JC/T845-1999 industrial standard.
