Advantages of  INTER-CHINA OPNE ROLL MILL/Open type Rubber Mixing Mill                                                                                                         


1. Good materials 

Cold cast iron is generally used as the material of roller. The surface texture of this material is hard, resistant to wear and corrosion; The internal toughness is good, the strength is big; Easy heat conduction, easy processing, and low cost.
Chilled cast iron rollers are divided into ordinary chilled cast iron (ltg-p) and alloy chilled cast iron (ltg-h).
Inter-China XSK Models all use alloyed chilled cast iron, thus having better surface hardness and working strength, so its service life is prolonged.


2. Safety device 





Features :                                                                                                                                                                                                                                                  


When the internal mixer is working, the two rotors rotate relative to each other, and the material from the feeding port is clamped into the roll gap and squeezed and sheared by the rotor.

After passing through the roll gap, the lower top edge is divided into two parts, respectively The gap between the front and rear chamber walls and the rotor is returned to the top of the nip.

During the week of the flow around the rotor, the material is sheared and rubbed everywhere, causing the temperature of the rubber to rise sharply and the viscosity to decrease, increasing the wettability of the rubber on the surface of the compounding agent so that the rubber is in full contact with the surface of the compounding agent.


The compounding agent agglomerates through the gap between the rotor and the rotor, the gap between the rotor and the upper and lower top cymbals, and the inner wall of the inner chamber with the rubber compound, is sheared and broken and is surrounded by the rubber which is stretched and deformed and is stabilized in a broken state.

At the same time, the ribs on the rotor move the rubber along the axial direction of the rotor to agitate and mix, so that the compounding agent is uniformly mixed in the rubber compound.

The compounding agent is repeatedly sheared and crushed, the rubber compound is repeatedly deformed and restored, and the rotor ribs are continuously stirred, so that the compounding agent is uniformly dispersed in the rubber compound and reaches a certain degree of dispersion.

Since the shearing action of the rubber compound during the mixing of the internal mixer is much larger than that of the open mill, the high temperature of the rubber mixing makes the mixing efficiency of the mixer very much higher than that of the open mill.







What' 's the difference between an Internal Mixer and an Open Mixer                                                                                                                                                          


At present, the use of Open Roll Mill is still very wide, now in many ways can be replaced by internal mixing machines, but Open Roll Mill still has practical significance.
1. It is necessary practical equipment in medium and small factories. Because the investment in an internal mixing machine is large, and the application of the mixer is not as wide as that of an Open Roll Mill.
2. Some mixing rubber with high heat sensitivity can avoid early vulcanization and facilitate heat dissipation, so it must be mixed with an open mixer.
3. Some manufacturers mix different colors of rubber, Open Roll Mill is easy for cleaning of machine.
4. Special rubber, such as nitrile-reinforced rubber.
