Introduction to 4-inch open mill

The 4-inch open mill, also known as the 4-inch rubber mixing machine, is one of the main equipment for mixing, refining, and producing sheets of high polymer materials such as rubber and plastic. The 4-inch open mill is a customized model specifically designed for universities, research institutions, and laboratory customers. It has a simple structural design, small footprint, easy operation, convenient mobility, and high safety factor. Used for plasticizing, mixing, hot refining, and flaking of high molecular weight materials such as rubber and plastic.

The open mill, also known as the open rubber mixing machine, is referred to as a two roll machine in plastic product factories. The open mill is a type of plastic mixing equipment that has been used in rubber and plastic factories for a long time. On the rolling mill production line, the open mill is located before the rolling mill and after the mixer, and its function is to mix and plasticize the uniformly mixed raw materials, providing a relatively uniform molten material for the rolling mill to roll and shape rubber products. When producing wire and cable materials, the open mill can directly mold the powdered material mixed according to the formula into a molten material, then press it into a sheet-like strip, and then cut it into granules in the granulator. On the floor leather production line, a uniformly mixed and plasticized base coating can be directly provided for the fabric leather. Recycled waste plastic films (sheets) can also be re molded and remade on an open mill.

Characteristics of 4-inch open mill

1. The core technology and main components come from Taiwan, Japan, and Germany;

2. The overall base plate is easy to install, and the transmission mode is single axis output to ensure high torque. Imported bearings reduce rubbing force to ensure power saving, low noise, and even and controllable rubber thickness;
3. The roller is made of vanadium titanium alloy cold hard cast iron, with a hard and wear-resistant surface that is durable Precision machining of the inner cavity of the roller ensures rapid and uniform cooling of the roller body;
4. The machine adopts manual distance adjustment, precise thickness control, and easy operation;
5. The machine is equipped with emergency brakes. In the event of an emergency, there are emergency switches at all four corners, which facilitate multi position braking and quick stopping of the machine;
6. The transmission device adopts a hard tooth surface reducer, which has a compact structure, high transmission efficiency, and low noise.

Working principle of 4-inch open mill

The main working components of the 4-inch open mill are two hollow rollers or drilling rollers that rotate inward in opposite directions. The device on the operator's side is called the front roller, which can be manually or electrically moved horizontally back and forth to adjust the roller distance and meet operational requirements; The rear roller is fixed and cannot move forward or backward. The two rollers are generally of the same size and rotate relative to each other at different speeds. Raw rubber or rubber material is rolled into the gap between the two rollers as the rollers rotate, and is subjected to strong shear to achieve the purpose of plasticizing or mixing. The open mill is mainly used in rubber/plastic and other fields.
