Open mill is an open type intermittent mixing equipment for plastic materials, consisting of two parallel arranged rollers with adjustable gap between them. Its main function is to mix and plasticize the uniformly mixed raw materials, providing a uniformly mixed and plasticized molten material for the rolling mill.

The open mill mainly relies on the squeezing and shearing effects of two relatively rotating drums on the rubber material during the rubber mixing process. After multiple kneading and mixing processes, chemical reactions are also carried out during the mixing process, breaking the large molecular chains inside the product and evenly mixing and dispersing various components inside the rubber material, ultimately achieving the purpose of rubber mixing.

Mainly used in the production of plastics and their products, polyolefins, PVC, films, rolls, profiles, polymer blending, pigments, color masterbatch, stabilizers, stabilizers and other industries. Its main purpose is to test the changes and comparisons of the physical properties of raw materials after mixing. For example, the dispersibility and translucency of colors, the glossiness of material surfaces, and the strength, plasticity, hardness, etc. after adding auxiliary materials.

1) High hardness chrome plated roller, high temperature resistance, fast thermal conductivity, and corrosion resistance.

2) Roller surface treatment process: rough machining, drilling, pre grinding, heat treatment, precision grinding, electroplating, grinding, polishing.

3) Specially customized heating rod, dynamic compensation, and PID self-tuning function to ensure temperature balance. Dynamic compensation and PID self-tuning function ensure temperature balance.

4) Gear reduction motor, high specific speed reduction motor, saves 80% energy compared to other transmission motors, coupled with heavy-duty hinge transmission, ensuring smooth operation and extremely low noise.

5) Using a precision screw to adjust the spacing between the rollers and a direct reading dial to obtain different rolling thicknesses of test pieces (adjustable spacing of 0.1-8mm) for testing purposes.

6) Complete emergency parking setup: Install a safety reverse door device in front of the box; Install a safety rod above the roller; Safety emergency stop devices can be installed at any position on the control panel; To ensure the maximum safe use of personnel and equipment.

7) Heating method: electric heating, fast and stable heating speed.

8) The design structure is simple and clear, easy to operate, and does not require installation. It can work by connecting wires and pipelines.

9) The rack, cover, and base are all welded structures that have undergone annealing and stress relief treatment, resulting in a beautiful and elegant appearance.
