CFine 75L High Efficiency Falling Type Internal Rubber Mixer
Product brief introduction
Designed for laboratory and small-scale use, the 75L experimental
internal mixer can handle a variety of materials such as EVA,
rubber, synthetic rubber, and hot melt adhesives. Formulas mixed in
this equipment can be transferred directly to industrial
production. With its durable, wear-resistant build, the machine
provides thorough blending and stable changes in material
properties. It is regarded as one of the most effective mixers for
teaching, sample making, and limited production runs.

Product Feature
1. Internal rubber mixer,film and wear-proof,suitable for mixing
and plasticing raw material like EVA Rubber,Hot melt gule and so
on.Nice Homogeneity of raw material can be achieved in company with
good physical property change.
2. Rotors and edges are machined in an integral way which results
in Strong carrying capacity.
3. All parts contacting with raw material directly are made of
superior alloy steel which makes the mixing chamber more
wear-proof,stable and anti-corrosion,long service life.
4. New design for leakage-proof of powder,easy to dismantle and
replace.
5. Hydraulic way makes raw material to be mixed more efficiently.
Working Principle of Internal Mixer
The two rotors in the mixing chamber rotate relative to each other
under a certain speed ratio, clamping the material from the feeding
port and bringing it into the roller gap to be squeezed and sheared
by the rotors. After passing through the roller gap, it hits the
sharp edge of the mixing chamber "W" and is divided into two parts,
respectively along the gap between the front and rear chamber walls
and the rotors and then returns to the top of the rotor. In the
closed mixing chamber, the material is strongly sheared and mixed
under certain pressure and temperature conditions, so that the
formula materials are fully dispersed and plasticized, so that the
formula can play the best effect.
Mixing system
The mixing chamber is "W" shaped, with an "M" shaped lower pressure
cover to form a fully enclosed mixing space. The stirring blade
adopts a prismatic spiral design without dead angles, so that the
material can be sheared and dispersed to meet the physical property
requirements. The stirring blade is a hollow structure, and the
part in contact with the material is made of high-carbon steel.
After quenching and tempering, vacuum 72 hours deep nitriding heat
treatment, the surface is plated with hard chrome to increase the
hardness, ensuring that the mixing chamber is strong and
wear-resistant. Wear-resistant, anti-corrosion, not easy to stick
to the material, and long service life.
Technical advantages
1. CFine's anti-leakage powder device adopts mechanical shaft seal
tightening technology and uses self-lubricating seal rings to keep
the seal rings in a compressed and sealed state during the mixing
process. The self-lubricating seal rings can further reduce the
wear of the mixing system and more effectively reduce the noise
such as whistling caused by leakage and poor sealing. It can
greatly improve the anti-leakage powder function, making cleaning,
color change and disassembly simpler and more convenient, and
reduce the pollution to the materials.
2. This machine adopts a through-type heating system, which heats
faster and transfers temperature more evenly, and the heating
efficiency is 50% higher than that of traditional heating plates.
It adopts a PLC program control system.
3. The internal structure of the mixing chamber adopts a complex
tube-belt design, which has good heat exchange and precise
temperature control. The rotor is cooled by water, which
effectively prevents sticky materials and controls the temperature
precisely, making the materials dispersed more evenly.
After-sales Service
