Aquatic special pressure roller shell material 

Using professional machine tools for processing. Output of the surface of the roller with the round size is small, high precision, with surface roughness of axis to beat small round cylindrical internal cylindrical surface cylindricity is high. Its high stability when using, and the life of the domestic leading level.

Ring die and the roller when using the matters needing attention:

1. The right to choose the appropriate die compression ratio.

2. Properly adjust the working gap between the ring die and roller, is between 0.1 ~ 0.3 mm (new pelletizer boot after roller pressure in ring die driven "turn not turn" state).

3. The new ring die used to match the new roller, roller and ring die before must be loose and tight. When the wedge Angle appears in roller pressure on both sides, should be timely hand grinder, grinding roller flange part, in order to good cooperation from the roller and ring die.

Must pass before 4. Raw materials into the granulator and magnetic separation process, at the beginning of reduced iron pressed into the die. And to periodically check the die, die for plugging in. Out in time or drill stuck die hole.

5. Feed ring mould taper hole in plastic forms of reducing its repair, repair ring should be paid attention to when the surface of the work in the lowest place should be 2 mm high increasing range at the bottom of the tank, and there is still a roller after the restoration of eccentric shaft adjustment allowance, otherwise the ring die should be scrapped.
