(1) First cut the bladder (curing bag) into large pieces about 15cm×20cm, then cut into particles about 10mm with knife breakdown mill ; as the IIR is easy to be heat and sticky, it is better to cut with water-cooled knife breakdown mill.(2）Coarsely mill the 10mm particles 3-5 times on the open mill (the roll pitch of the open mill is 1.0mm—2.0mm), when it begins to sheet, add reclaiming agent RDS-IIR(II) and 5 parts by weight of paraffin oil, and continue to mill until it becomes even(about 5-10 times) and get down the open mill.(3) Mill run 3 times on the second open mill (the roll pitch is 0.6mm—1.0mm) and get down the open mill.

(4) Refine twice on the ref ining mil l ( the rol l pi tch is 0.3mm—0.8mm) and sheet.Note: The roll temperature of the open mill should be 60�-70�. The roll temperature of the refining mill should be below 90�.

RDS-IIR(II) IIR curing bladder and curing bag reviving agent can also be used when the internal mixer is at high temperature.
