the process : kneader dispersion mixer - cone double feeding machine - single screw extruder--- brace head and net exchanger--sheet mold --3 rollers calender --cooling stacker--sheet cutter
1.The Wide width rubber/plastic sheet extrusion line is mainly composed of cold feeding pin extruding system, the double-roll calendering system, the six-roll cooling system, the rubber sheet combining system, double-station packing system, etc.
2.The rubber cover of conveyor belt is produced in the following procession, the fully plasticating in the pin-extruder, and then the passing from the extruding die with the help of the double-roll calendering system.
3.The cover wide width of less than 2600mm and thickness of 1.5~1.8mm, is produced without the problem of bubble and fish scale in this procession. And also the additional function, such as rubber covering on the flame retardant belt, can be realized if the production line is equipped with other necessary device.
