• 23/10/2012 - The New Double Planetary Mixer

The double planetary mixer has several features that make it a better choice. Items that come standard with the mixer include pre-wired controls, enclosed construction, self contained unit and variable speed inverter drives.
Mixing efficiency must be considered when expanding the process industry. Mixers are not a generic tool used for production but rather a decisive tool for the business. Labs must remain competitive with other businesses and also remain profitable. They simply must be cost effective as well as efficient. This means that every type of mixer must be considered when looking at increasing productivity.
There are three main types of mixer designs to consider, a Double Planetary Mixer, a Planetary/Disperser and a Dual Shaft Mixer. The main difference with these three types is the mixing approach. The Dual Shaft Mixer as well as the Planetary/Disperser starts with a liquid and builds thickness as solids are added. This order is reversed in the Double Planetary Mixer. The increased viscosity develops the high level of shear that is needed to disperse without using a high speed disperser. Then a small amount of liquid can be added to get the right thickness.
It is an all-in-one mixer which has control options such as turnkey automation, a simple interface as well as data logging capabilities. It can provide for proper heat transfer, change can design, and manage vacuum pressure. It has three blade designs from which to choose. This enables you to choose the right flow pattern for the batch being mixed.
Newly designed HV blades allow for mixing high viscosity products. Rectangular blades are ideal for wet or dry blending. They are productive no matter what the consistency is and what the batch's flow characteristics consist of. Finger blades are preferable for mixing fibers or delicate solids. They can be custom designed and fine tuned for a particular flow.
For materials that are very thick the HV blades are preferred. Silicone sealants, molding compounds and heavy hot melts are all the types of batches that the HV blades would work well with. However, for solid butyl mixtures the double arm mixer is better because it is better designed to break up solid rubber chunks.
The HV blades are also well designed to handle sticky substances. Carbon fillers and other applications that tend to try to climb the blades and stick to lower crossbars like those in a double planetary mixer seem to do well with HV blades. Since the lower crossbar is not included in models with HV blades this does not pose a problem.

• 23/10/2012 - Consider The Advantages Of Mixing Under Vacuum

Selecting a mixer used to be a rather easy task, just choose the one that's been working the best. However, over the last few years it has become more complicated because of all the changes and improvements that have occurred. It takes careful planning to find the one that will do the job. One must consider efficiency, conservation of time and space. And of course what is at the forefront of any lab manager's mind is the initial cost as well as any other overhead associated with production.
You are required to understand about all the functions that can be easily performed during the mixing cycle and then you have to just guess the cycle or procedure through which you can find the technique so that vacuum can be easily used in your application. A vacuum just proves to be a savior if you had chosen the right technique and equipment. The process of vacuum helps in making your procedure productive and the plant which is used by you becomes more eco-friendly and has less affect on environment.
Some processes which can help you reach your goals are been discussed below. Read below to find them out. De-oxidation can be the vital step for your cycle. The degradation of some useful and highly sensitive instruments can be easily prevented through de-oxidation. The removal of oxygen helps in manipulating the various conditions according to our will. Many unwanted and useless reactions are checked through this process. This then indirectly minimizes the growth of microbes.
Vacuum driving is another option that could provide you with various benefits. You can choose to employ the vacuum drying for your processes. You can use it for drying various materials particularly which are heat sensitive eliminating the fear of degradation due to heat.
But, it's very necessary that you are able to find out the vacuum mixers that just fulfill all your requirements. For finding out the best vacuum mixers, you are first required to follow the basic three steps. You are first of all required to define and explain all your process parameters elaborately to your manufacturer for its proper fabrication. Then, ask your manufacturer about his experience and finally test the varieties of equipments available.
You should be at alert while choosing the correct vacuum mixer as your decision holds vital importance.
You can choose to go for some low maintenance or low cost options. High pressure homogenizers' orifices are generally chocked due to the mechanical seals and clog failure. If you opt for cleaning the orifices then, charges that are charged by labour are more and this makes the process expensive. So, such types of equipments always make your work easier and also reduce the unwanted stress.
