How to choose an internal mixer?

When purchasing an internal mixer, it is best to choose companies with professional services and excellent quality products. This way, your interests will be protected in your future use and there will be no quality problems. Even if there are occasional problems, you can get them. Comprehensive after-sales service.
Dongguan Changfeng Machinery is a manufacturer with its own R&D team and manufacturers. It can customize machines according to customer needs and has a laboratory with various equipment (internal mixer, granulator, open mill, high mixing machine, crusher...) can be provided free of charge to interested customers for free trial.
Let’s briefly talk about the types of internal mixers. From the perspective of cleaning materials, they are generally divided into flip-type internal mixers and open-close type internal mixers. , If you are making ordinary rubber, silica gel and other materials, a flip-type internal mixer can meet the requirements. It is very convenient to turn over and clean the materials. . If you encounter very valuable materials or materials that are difficult to clean, it is very suitable to choose a split-type internal mixer because the mixing chamber of the split-type internal mixer can be fully opened and even the rotor can be pulled out for cleaning.
Judging from the characteristics of the mixing materials, there are internal mixers for rubber, silicone and other materials, metal powder internal mixers, ceramic powder internal mixers, and new material internal mixers. According to different material characteristics, the mixing chamber and rotor of Changfeng internal mixer have different special spray treatments.
Where is the quality of the internal mixer reflected?
Whether the configuration of the internal mixer is from a well-known brand such as motor, reducer, cylinder, etc. The brand directly determines the service life of the internal mixer.
The material and angle of the rotor
Generally, the rotor is made of stainless steel, but the rotor axis of the Changfeng internal mixer
is made of #carbon steel precision-cast in one piece, heat treated, tempered, and deeply nitrided. Thickness - hardness - ensures the hardness of the rotor shaft, high load-bearing capacity, high torque and strong and continuous shaft. The rotor blades
are made of high-carbon steel precision-cast and integrated with wear-resistant carbide, high-precision polishing, penetration, and surface hard chromium plating to ensure wear resistance and durability.
Look at the dispersion effect of the material: If the formula is mature, the quality of the dispersion effect directly reflects the quality of an internal mixer. The rotor of the internal mixer produced by Changfeng is a diamond-shaped design with two leaves and four edges. There are no dead corners in the mixing chamber. Customer experiments and comparisons have proven that the design of the Changfeng internal mixer is very reasonable and the dispersion effect is relatively the best.
Powder leakage in the internal mixer. Powder leakage is a technical bottleneck. However, the Changfeng internal mixer has been greatly improved. It adopts dry mechanical shaft seal technology to prevent powder leakage, which is very effective.
Heating and cooling effect Changfeng internal mixer adopts heating tube penetrating heating pulse type heating. After testing, it only takes minutes for the flip-type internal mixer to heat to ℃. There is an automatic temperature control system that will pass water for cooling when the temperature exceeds the set temperature.
For powder materials, the Changfeng internal mixer is equipped with a frequency converter, which can adjust the frequency and speed. It first rotates slowly until the material is melted, and then rotates at full speed without causing dust to fly.
For metal powder, zirconia, alumina, cemented carbide or other special materials, the mixing chamber and rotor (all parts in contact with materials) of Changfeng internal mixer are sprayed with tungsten carbide. This spraying technology is Changfeng's patent. Patent number: . Counterfeiting of patented products will be investigated.
Changfengte launches a continuous internal mixer (double-rotor continuous internal mixer) for color masterbatch, retardant materials, modified materials, elastomers, etc. This mixer has two mixing rotors. The working principle is similar to that of an internal mixer, but it continuously feeds and discharges materials like a twin-screw. The material is naturally exhausted after being discharged from the mixer (the exhaust effect is very good). Productivity is based on feed rate. To maintain a constant feed supply, you can increase the rotor speed to obtain greater shear force or close the discharge door slightly to increase the discharging temperature.
When purchasing an internal mixer, it is safe to consider the price, the strength of the manufacturer, the quality of the machine, and the after-sales service.
