Strock blender mixing mill introduce:
Strock blender mixing mill is a widely used equipment in rubber processing. The following is an introduction to it:
1. Working principle
The rubber mixing mill mainly uses two relatively rotating rollers to extrude, shear and stretch the rubber, thereby realizing the rubber plasticizing and mixing processes. The rubber turning device plays an auxiliary role in this process. It can regularly turn over and remix the rubber adhering to the rollers to ensure that the rubber is evenly heated and sheared during the processing, and improve the mixing effect and product quality.
2. Structural composition
1. Roller: It is the core component of the mixing mill, usually
made of alloy steel, with a special surface treatment, and has good
wear resistance and corrosion resistance. Parameters such as the
diameter, length and speed of the roller will be selected according
to different processing requirements.
2. Drive device: including motors, reducers, etc., to provide power
for the rotation of the rollers. The power and speed control
accuracy of the drive device directly affect the production
efficiency and product quality of the mixing mill.
3. Rubber turning device:
- Rubber turning roller: located above or below the roller, driven
by a specific mechanism, it can periodically turn the rubber on the
roller. The shape and size of the rubber turning roller will be
designed according to the specifications and processing
requirements of the open mill.
- Driving mechanism: It can be hydraulically driven, mechanically
driven or electrically driven, etc., responsible for controlling
the movement of the rubber turning roller. The stability and
reliability of the driving mechanism are crucial to the normal
operation of the rubber turning device.
4. Spacing device: used to adjust the spacing between the two
rollers to meet the processing requirements of rubber of different
thicknesses. The spacing device is usually operated manually or
automatically.
5. Safety device: including emergency brake device, safety shield,
etc. to ensure the safety of operators. During the operation of the
open mill, if an abnormal situation occurs, the safety device can
stop the equipment operation in time to avoid accidents.
3. Advantages
1. Improve the mixing effect: The rubber turning device can
continuously turn and remix the rubber, so that the various
compounding agents in the rubber are more evenly dispersed, thereby
improving the mixing effect of the rubber.
2. Prevent rubber from overheating: By turning the rubber
regularly, it can avoid local overheating caused by long-term stay
of the rubber on the roller, and reduce the risk of scorching of
the rubber.
3. Improve production efficiency: The automated operation of the
rubber turning device can reduce manual intervention and improve
production efficiency. At the same time, it can also reduce the
waste of rubber in the processing process and reduce production
costs.
4. Adapt to different rubber varieties: The rubber mixing mill of
the rubber turning device can be applied to various types of rubber
processing, including natural rubber, synthetic rubber, recycled
rubber, etc.
IV. Application field
The rubber mixing mill of the rubber turning device is widely used
in the rubber products industry, such as tire manufacturing, rubber
tube production, rubber seal manufacturing, etc. It can be used in
rubber plasticizing, mixing, hot refining and other processes to
provide high-quality rubber raw materials for the production of
rubber products.
