4-inch experimental open mill is easy to clean.

I: Introduction to Open Mixing Mill
The main working components are two hollow or drilled rollers that rotate inward in opposite directions. The roller on the operator's side is called the front roller, which can be moved horizontally back and forth manually or electrically to adjust the roll gap and meet operational requirements. The rear roller is fixed and cannot move back and forth. Both rollers are of the same size and rotate relative to each other at different speeds. Raw rubber or compound is drawn into the gap between the rollers as they rotate, subjected to intense shearing to achieve the purpose of plasticizing or mixing. Open mixing mills are also used in sectors such as plastic processing.

II: Features of 4-inch Laboratory Open Mixing Mill | Small Open Mixing Mill | Sampling Open Mixing Mill 
The small open mixing mill is designed for experiments in factories, research institutions, and universities, as well as for formula development. Its structural design is simple, occupying a small footprint, easy to operate, easy to move, and with a high safety factor. The technology for small open mixing mills in China has reached a very mature level and has been recognized by domestic universities and research institutions, with exports to international markets.
Applicable products include: silicone rubber products, plastic products, polymer materials, engineering materials, etc.
Standard models include: 4-inch (120*320); 6-inch (160*350); 9-inch (228*600), and other conventional models.

1. Core technology and main components are sourced from Taiwan;

2. The electrical control part uses imported electrical components, ensuring convenient operation and stable performance;

3. Gap adjustment methods include manual or electric options;

4. Integrated baseplate for easy installation; single-axis output transmission ensures high torque; imported bearings reduce friction, ensuring energy savings, low noise, and uniform, parallel, controllable compound thickness;

5. Rollers are made of vanadium-titanium alloy chilled cast iron, with a hard, wear-resistant, and durable surface. The inner cavity of the rollers is precision-machined to ensure rapid and uniform cooling;

6. Roller bearing positions use rolling bearings, and lubrication is provided by grease;

7. The machine is equipped with an emergency brake. In case of an emergency, emergency switches at all four corners allow multi-point braking, enabling the machine to stop quickly. Pulling the emergency switch immediately stops the machine, ensuring safety and reliability;

8. The transmission system uses a hard-gear surface reducer, featuring compact structure, high transmission efficiency, low noise, and long service life;

9. The machine is equipped with an overload protection device to protect key components from damage due to overload.
