Product Description
Compact/B type rubber mixing mill
The following is an introduction to its structural features,
working principle, application areas, technical parameters, etc.:
Structural features
Compact design: The overall structure is compact and occupies a
small area. The overall length of the equipment is usually only 3/4
of that of an ordinary rubber mixer. It is easy to install, operate
and move, which can save plant space and is very suitable for
production workshops or laboratories with limited space.
Double roller design: With a double roller structure, the two
rollers cooperate with each other to achieve the rubber mixing,
plasticizing and other processes. The rollers are usually made of
solid high-carbon steel material, chrome-plated on the surface,
with high hardness and wear resistance, and can withstand the high
pressure and friction during the rubber mixing process.
Working principle
Transmission system: Equipped with hardened gear reducer, the gears
are processed by carburizing and quenching, and the surface is
finely ground to improve the processing accuracy and wear
resistance, while reducing the operating noise.
Gap adjustment device: The gap between the rollers is adjustable,
and there are two adjustment methods: manual and electric. It can
accurately adjust the gap between the rollers according to
different process requirements to control the thickness and quality
of rubber products.
How it works
Shearing and extrusion: The two rollers rotate relative to each
other at different speeds, so that the rubber material is subjected
to strong shearing and extrusion in the gap between the rollers,
thereby achieving plasticization and mixing of the rubber, and
fully mixing the raw rubber and various compounding agents.
Frictional heat: During the mixing process, the friction between
the rubber and the rollers and inside the rubber will generate
heat, which will increase the temperature of the rubber, help speed
up the mixing process and improve the mixing effect.
Application areas
Rubber product production: It is widely used in the production
process of rubber products such as tires, cables, hoses, tapes,
rubber soles, etc. It is one of the key equipment for rubber
product manufacturers.
Laboratory research: Due to its compact design and small processing
capacity, it is also very suitable for laboratory research and
development of rubber formulations and preparation of small batches
of samples, making it convenient for researchers to test and
optimize the performance of rubber materials.
Technical parameters
Safety protection: Operators must strictly abide by safety
operating procedures when operating equipment and wear personal
protective equipment, such as safety helmets, protective gloves,
etc. to avoid accidents.
Equipment inspection: Before starting the machine, a comprehensive
inspection of the equipment is required, including whether the
roller surface is smooth, whether the transmission system is
normal, whether the lubrication system is in good condition,
whether the electrical control system is sensitive, etc., to ensure
that the equipment is in normal operation.
Process control: Strictly control the mixing temperature, time,
roller distance and other parameters according to the process
requirements to avoid quality problems of rubber products caused by
improper parameter settings.
