Two roll mill, also known as a mixing mill or a rubber mill, is a machine used in the rubber and plastic processing industries for mixing and compounding materials. It typically consists of two horizontally placed parallel rolls that rotate towards each other at different speeds.
Two roll mill are widely used in the rubber industry for mixing and processing rubber compounds used in tire manufacturing, rubber parts production, and various other applications. They are also used in the plastics industry for mixing polymer compounds, colorants, and additives to produce plastic products with desired properties.

Roller of the open mixing mill:
Roller treatment:The roller is made of high quality carbon steel, which is treated by nitriding, the surface is coated by chromium, the bearing capacity is strong, making the service life longer.
Roller structure: Medium hole roller, roller hardness (Hs) 58-65. Fine machining inner cavity of the roller ensures that the roller body cools quickly and evenly.

Open Mill New Safety System:
1. Infrared Sensor: A infrared sensor device for braking is installed to keep the operator's body and the running Two Roll Open Mill in a safe distance. Many unexpected accidents on the Open Milling Machine are caused by causal and incorrect operations, this infrared sensor is designed to rule the operator's basic actions and protect the user from the roof of the danger.
2. 360 Degrees Emergency Braking Button: Based on human engineering, this safety device is designed to protect the user when an emergency happened. This technology has applied China's National Patent. When touching the button, the rollers will stop immediately and reverse 1/4 round to maximize the protection.
3. Knee-Hitting Safety Device: According to human engineering, this device is installed to brake the rollers when an unexpected emergency occurred.
4. Hand-Pressing Safety Device: This is the basic safety device installed on all types of Rubber and Plastic Two Roll Mill. Once press the button, the rollers will stop immediately and reverse about 1/4 round.
5. Safety Cover: This safety cover is installed on the top of the rolls, to ensure the user's safety when adding other solid, powder or liquid additives into the mixing materials.



Intelligent control panel and PLC control system:
1. Real-time data record and export of kneading time, temperature (mixing chamber and front/rear rotors), ram pressure, current, torque and recipe code.
2. The control system can be set up to 20 mixing steps, save 20 recipe spaces.
3. The control system is capable of remote import of the process recipe and data monitoring, communicating with MES via Ethernet communication interface.
4. An Ethernet communication interface and 20% of the control points are reserved. Touch screen is provided.
