Double Planetary Kneader (PDP series, PDP-30)
INTRODUCTION:
The PerMix PDP series Double Planetary Kneader is also called double planetary kneader mixer, because it can be used to handle very viscous materials up to 1, 500, 000 cPs. Usually the PerMix PDP series Double Planetary Kneader has two vertically mounted mixing tools which are driven by one gear to move around the central axe of the tank as well as their own axes.
The PerMix PDP series Double Planetary Kneader is so versatile that it can be used to mix, knead, stir and deaerate all types of material, including highly viscous pastes, even to granulate wet powders. Industrial pastes produces by the PerMix PDP series Double Planetary Kneader include concentrated paints and varnishes, printing inks, fillers, silicone and thiocole pastes, plastisoles, plastic coatings, synthetic lubricating greases and many other materials.
HOW IT WORKS:
In the mixing process, two vertically mounted mixing tools rotate around a common sun gear. In addition, they rotate at a higher speed around their own axes, according to the planetary principle. A swinging type scraper continually sweeps the inside wall, transporting material from the walls of the vessel to the mixing tools, and transferring the heat efficiently.
DESIGN FEATURES:
The standard finger-blade mixing tools are designed to work in an overlapping way, thus create strong axial and radial motions in the mix-product, as well as a highly intensive shearing and dispersing effect. Within a short time, the material is thoroughly mixed and even very difficult formulas may be obtained.
A quick vessel locking device connects the mixing vessel to the mixer. Because the vessel is mounted on fixed and swivel wheels, it is very easy to transport. The standard version of the PerMix PDP series Double Planetary Kneader features dual mixing tools shafts running in heavy duty ball bearings. Both mixing tools and scrapers can be supplied with a special bayonet locking system for easy disassembly. The upper head of the machine is lifted by manual, mechanical or hydraulic elevating systems, depending on the size of the machine.
Electrical TEFC single speed motors are the standard drive units supplied with PerMix PDP series Double Planetary Kneader. Ex-proof design motors and gearswitches are also available. Among the many options available for special applications are: Infinity variable speeds, two speed drives, hydraulic drive units, heating/cooling jacket, vacuum/pressurized operation, etc.
SPECIAL DESIGNS:
PerMix designs the Double Planetary Kneader according to the special requirements and applications of the customer. Some modifications include:
1. For mixed products that must be heated or cooled, PerMix has designed jacketed vessels for hot oil, electrical heating, steam heating and liquid cooling.
2. PerMix has designed moveable and tiltable mixing vessels, with or without a bottom discharge valve for less viscous liquids and units with a special no dead area valve for connection to peripheral equipment. Arrangements can be made for the transport of the vessel by forklift or by crane.
3. Where necessary, alterations can be made in the shape of the mixing tools; A third mixing tool may be added; A homogenizer unit (with deflector) can be supplied - and other performance proven mixing elements may be supplied for special duties.
4. A PerMix DISSOLVER UNIT for fine dispersion, with its own drive unit, available with or without variable speed, has proven itself a good process accelerator for dealing with special dispersions.
1. All specifications are as accurate as is reasonably possible, but they are not binding.
2. Customized sizes are available against request.
3. PerMix reserves the right to modify the design without notice.
FAQ:
Q: What is your price level compared with European suppliers and local Chinese suppliers?
A: Depending on the machine type and size, our price level is 30%-60% less than the European suppliers and 5-15% higher than the big local suppliers.
Q: Are you able to provide tailor-made design and production for the mixers?
A: Yes, in fact more than half of our mixers are tailor made, which is one of our strong points.
Q: Are you able to design and produce other processing equipment?
A: We are open to discuss about it.
Q: Can you provide machines to OEM customers, meaning to label their brands on the machines.
A: Yes we are doing it a lot. We have several OEM partners in the USA.
Q: Do you have agent network out of China?
A: Yes we do have agents but only in some countries, for example in USA, Germany, Poland, Spain, Denmark, Turkey, Argentina, etc. We are still looking for more agents because we believe to work with agents is the best way to do business.
Q: What is your delivery lead time of the mixing equipment.
A: Depending on the size and level of customization, but usually it is from 6-14 weeks.
Q: How do you pack and ship the mixing machines?
A: For machines don't require full container loading, we will pack them in wooden case. For FCL (full container loading) shipment, we will just wrap the machines in plastic films and fix them in the container. The shipment can be either by air or by sea
