Abbreviation for open mixing mill. A rubber mixing machine with exposed rollers used in the rubber factory to prepare plastic rubber, compound rubber, or perform heat refining and molding.

The main working parts are two hollow rollers or drilled rollers that rotate in different directions. The front roller is installed on the operator side. It can be moved back and forth horizontally by manual or electric action to adjust the roller.To meet the operating requirements, the rear roller is fixed and cannot be moved forwards and backwards. The two rollers are generally the same in size, and each rotates at different speeds. The raw rubber or rubber material is rolled into two with the rotation of the rollers.The gap between the rods is subjected to strong shearing to achieve the purpose of plasticizing or mixing. open mixing mill are also used in plastics processing and other sectors.

The open mixing mill is the abbreviation of the open rubber mixing machine. In plastic products factories, people are used to calling it a two-roll machine. The open mixing mill is before the calender and after the mixer, and the function is to mix the raw materials uniformly.It is mixed and plasticized to provide a more uniformly mixed molten material for the calendering of plastic products. When producing cables, the mill can directly smelt the powdery materials mixed according to the formula into a melt. The molten material is then calendered into a sheet-like belt, and the pelletizer is cut into granules. On the floor production line, it can directly provide the fabric leather with a uniformly mixed and plasticized primer, and it can also use recycled waste plastic film

Re-plasticize and re-process on the open mixing mill.


Features of 4 inch lab two roll mill
1. The core technology and main components are from Taiwan
2. The overall bottom plate is easy to install. The transmission mode is single-shaft output to ensure large torque. Imported bearings reduce friction to ensure power saving and low noise. The thickness of the rubber is uniform and parallel and controllable.
3. The roller is made of rice-titanium alloy chilled cast iron, the surface is hard and wear-resistant, durable, and the inner cavity of the roller is finely added to ensure that the roller body cools quickly and evenly.
4. The machine adopts manual distance adjustment, precise thickness adjustment and convenient operation
5. The machine is equipped with emergency brake. When an emergency occurs, there are emergency switches at the four corners, which is convenient for multi-position braking and convenient for the machine to stop quickly
6. The transmission device adopts a hard gear surface reducer, which has a compact structure, high transmission efficiency and low noise
