The open mixer is a machine used to prepare plasticizer and mixing rubber, and the mixer is mainly used for rubber plasticizer and mixing. Today, we will introduce the main differences between the open mixer and the mixer:
The open mill is a two-roll machine, which uses the shear force generated by the two rollers moving relative to each other at different speeds to plasticize. In the process of operation, the rubber material should be continuously triangle wrapped or crimped. The mixer uses the regular contraction of space generated by the relative movement of the internal designed blade to generate shear force, without manual operation and labor saving.
The open mill is simple in structure and low in cost, but it has great labor intensity, great pollution and great harm to workers. Mixers are more expensive, but can be heated, vacuumed, and pressurized to handle materials that are difficult to plasticize. Low labor intensity and strong adaptability. The mixing amount of the open mixer is small, and various dosages are better, and because it is open, heat dissipation is fast, the temperature effect is not so obvious, and if the temperature is relatively high, you can stop the mixer for a period of time, let it cool and then mix; The mixing machine may be several times the mixing machine, the mixing process needs to strictly control the temperature change, but also control the order of adding small materials, which will affect the uniformity of mixing and coke; There is also the discharge temperature must be strictly controlled, the temperature in the mixer and the rubber temperature difference is large, so the temperature relationship must be considered when controlling the temperature, otherwise the rubber is easy to scorch (the general rubber internal temperature is 50-60 degrees higher than the temperature in the machine).
The above points are the difference between the open mill and the mixer, the application of the open mill is more harmful to the human body, and the mixer is more labor-saving, while the open mill and the mixer are also different in the use of temperature, although they are rubber refining machines, but there are still some differences.
