Humanized PLC Control 14 Inch Lab Two Roll Mill
Product Introduction
Two roll mixing machines are engineered to provide unmatched performance for masticating and kneading natural rubber, synthetic rubber, EVA, or PVC pellets with various chemical materials. This machine is primarily used for plasticizing, hot milling, and mixing of natural and synthetic rubber in rubber product manufacturing facilities.
Key Features
- Construction of mill rolls: drilled roll, bored roll, grooved roll
- Customizable speed ratio designed according to customer formulas and processing requirements
- Frame, frame cap and base are welded and treated by annealing for stress relieving
