Choosing a good open mixing mill for rubber involves considering several key factors to ensure you get a machine that meets your needs and offers long-term reliability. Here are some important aspects to consider:  

1：Roll Size: Consider the diameter and length of the rolls. Larger rolls can process more material but require more space and power.

2：Material: Rolls are typically made from chilled cast iron, forged steel, or other high-strength materials.

3：Motor Size: Ensure the motor has adequate power to handle the material and production volume

4：Heating/Cooling: Ensure the mill has an efficient temperature control system to maintain the desired processing  

5：Emergency Stops: Look for mills with easily accessible emergency stop buttons.

6：Lubrication System: Look for mills with automated or easy-to-access lubrication systems.

7：Frame Construction: A solid, durable frame reduces vibrations and ensures longevity.High-quality bushings reduce wear and improve the lifespan of the mill

8：Control System

Manual vs. Automated: Decide if you need a basic manual control or an advanced automated control system

By carefully considering these factors, you can choose an open mixing mill that meets your production requirements, ensures safety, and provides long-term reliability.
