I. USAGE:
Mainly used for plasticating crude rubber, mixing of rubber materials, warming up of mixed rubber and pressing to sheets etc.
1. PLASTICATING.
2. MILLING /MIXING.
3. HOT MILLING.
4. SUPPLING RUBBER.
5. FOR LAB.
II. STRUCTURE.
This machine is consist of ROLL, BERING, FRAME, CROSSBEAM etc MAIN COMPONENTS & DRIVER, THE DEVICE FOR REGULATING THE ROLL GA, SAFETY DEVICE AND BRAKE, THE DEVICE FOR REGULATING THE TEMPERATURELUBRICATOR etc.
III. WORKING PRINCPLE
Two roller mill (roll) at different speeds (struts. Velocity. Configfile The Velocity) is the relative rotation, the rubber is added to the roller, roller squeeze, due to friction (various friction) and adhesion(coherent force) the role of being drawn into the gap of the two rollers (roll gap), the plastic material in the gap are strongly squeezed (squzze) and shear (shear), so as to achieve the purpose of processing plastic materials. Discharged from the roll gap blanks coated ("rolling around) two roller surface velocity and temperature differences in return between the two rollers on a roller, so repeatedly, to complete mixing (milling) role.
IV. ROLLER WORKING TEMPERATURE
Have a great impact outside the operating temperature refining machine processing performance. To mastication of rubber, the temperature of the lower roller may have better mastication effect. Natural rubber is easy to package hot roll, when the mixing is usually before the roll temperature was controlled at 55 ~ 60 C, 50 ~ 55 C after the roll. The majority of synthetic rubber in the mixing heat is, so two roll temperature should be 5 ~ 10 ° C lower than that of natural rubber, while the majority of synthetic rubber is easy to package cold roll before the roll temperature is lower than the roller temperature.
