What is the difference between an internal mixer and an open mixer
Internal mixer and open mixer are two commonly used machines in rubber production, and they play a crucial role in rubber production. Although both machines are used for rubber processing, there are significant differences in their working principle, structure, performance, and usage. This article will compare and analyze the internal mixer and open mixer from these aspects, in order to better understand the differences between internal mixer and open mixer.
##Working principle
Internal mixer is a high-speed mixer mainly used for mixing high viscosity and high hardness rubber. The working principle of an internal mixer is to put various rubber raw materials and additives into the machine, and mix them through a high-speed rotating blade and mixer to achieve a uniform mixing effect.
The open mixer is a low-speed mixer mainly used for mixing low viscosity and low hardness rubber. The working principle of the mixer is to put rubber raw materials and additives into the machine, and squeeze and mix the rubber raw materials through two mutually rotating rollers to achieve a uniform mixing effect.
Therefore, there is a significant difference in the working principle between the internal mixer and the open mixer. The internal mixer has a fast mixing speed and good mixing effect, suitable for high hardness and high viscosity rubber raw materials, while the open mixer has a slow mixing speed and relatively poor mixing effect, suitable for low hardness and low viscosity rubber raw materials.
##Structure
There are also significant differences in the structure between internal mixer and open mixer. A mixer is usually composed of a frame, motor, reducer, blades, and agitator, and its structure is relatively simple. The open mill is composed of a frame, motor, reducer, rollers, and bearings, and its structure is relatively complex.
In addition, there are differences in size and weight between the internal mixer and the open mixer. Due to the need for high-speed rotating blades and mixers in the internal mixer, its size and weight are relatively small, while the opening mixer requires two larger rollers, so its size and weight are relatively large.
##Performance
There are also significant differences in the performance between the internal mixer and the open mixer. The internal mixer has fast mixing speed and good mixing effect, suitable for rubber raw materials with high hardness and high viscosity. The mixing speed of the mixer is relatively slow and the mixing effect is relatively poor, but it can mix low hardness and low viscosity rubber raw materials.
In addition, due to the fast mixing speed of the internal mixer, it requires higher electrical power and better heat dissipation performance. The mixing speed of the opening mill is slower, therefore requiring lower electrical power and better sealing performance.
##Purpose
There are also differences in the use of internal mixer and open mixer in rubber production. The internal mixer is mainly used for mixing high hardness and high viscosity rubber raw materials, such as tire rubber, leather rubber, etc. It can also be used for mixing various rubber additives. The open mill is mainly used for mixing low hardness and low viscosity rubber raw materials, such as pipeline rubber, sealing rubber, etc.
##Summary
In summary, there are significant differences between the internal mixer and the open mixer in terms of working principle, structure, performance, and usage. The internal mixer is mainly used for mixing high hardness and high viscosity rubber raw materials, with fast mixing speed and good mixing effect, suitable for tire rubber, leather rubber, etc; The mixer is mainly used for mixing low hardness and low viscosity rubber raw materials, with relatively slow mixing speed and poor mixing effect. It is suitable for pipeline rubber, sealing rubber, etc. Therefore, in rubber production, selecting suitable machines is crucial for the quality and efficiency of rubber production.
