300mm 400mm Open Two Roll Mill For EVA Or PVC Pellets
Application
Plastic open two roll mixing mill. It is widely used in rubbers and plastics industry for polymer mixing, such as PVC, color master batch. It consists of roll, bearing, gap adjusting device, electric control system, safety device, etc.Rubber factories produce rubber machines for refining rubber, mixing rubber or thermal refining.
Introduction:
Double drum is designed to chew natural rubber, synthetic rubber, EVA or PVC particles and various chemicals. It is mainly used in plastic and rubber products, hot rolling mill, mixer of natural rubber and synthetic rubber.
Feature:
1. We can design speed ratio as per customers' formula and processing requirements.
2. Rolls material is chilled cast alloy iron which hardness is reach to 70HB.
3. Frame, frame cap and base are welded and treated by annealing for stress relieving.
4. Human nature designed controlling system ensure labor safety.
5. Auto feeding oil or grease lubrication, it is easy to maintain and protect machine.
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.
