Read All About: Planetary Mixers


Introduction
The work head of the planetary mixer generally comprises two mixing paddles and one scraper. The two paddles rotate around their own axis while revolving along the internal wall of the container. The rotation and revolution of the paddles and scraper bring the peripheral materials to the interior. After one revolution, the paddles have passed through the entire internal space, after 3 rounds, most of the materials sufficiently mixed and all materials thoroughly mixed after only 36 revolutions.

These mixers are suitable for mixing high viscosity pastes and liquids and are excellent for de-aeration processes ensuring a homogenous mix.

Characteristics
1. It is a highly efficient, multifunctional mixer. It can combine reactions, mixing, blending and dispersion.
2. The planetary mixer is suitable for the production involving  liquid-liquid, solid-liquid, ointment-ointment, powder-ointment and materials with a wide variance in densities and proportions from low to high viscosity.
3. The mechanical seal and soft seal between the vessels enable the materials to be processed under vacuum conditions.

4. The vessel body can be heated by electricity, steam, water or oil.
5. The jacket structure can facilitate both heating up and cooling down.
6. The vessel inner wall is processed is usually highly polished ensuring the rotating wall scraper removes materials stuck on the inner wall.
7. The agitators will rotate as it revolves to thoroughly mix the materials. The mixing effect will be obtained within a short period and is typically more than ten times faster than normal mixers.
8. The rotation and revolution of the agitator and the scraper can be easily controlled by motor inverters.
9. It can be equipped with the extruder.

10. Different mixing forms are available as options according to different process.

Top Ten Tips when Selecting Mixers for Powder Blending

The mixing or blending of powder ingredients is a common industrial process practiced in many industries including chemicals, pharmaceuticals, minerals and food.

The choice of Mixer can be complicated but the following Top Ten Tips may help you make your final decision.

1.     Batch or Continuous?
One of the first questions to ask is whether a batch or continuous mixer is required. Here we look at considerations for selecting the right equipment for batch mixing. In batch mixing the whole batch can be identified and is traceable to help with overall quality control. Batch operations are very versatile and one Blender can be used for blending several ingredients together and for multipurpose operations.

2.     Batch Size
Don’t assume that biggest is best! Some mixer types may not achieve a full homogeneous mix when the mixing time is extended or when the volume is large.

3.     Mixing Time
The shorter the mixing time to achieve a homogeneous mix then the lower the costs will be and there will be less product degradation with sensitive materials. Look for efficiency in blending operations with gentle actions. Perry Process Equipment Ltd has a wide range of quality used mixers that meet this requirement.

4.     Power Consumption
With over increasing energy costs, it is important to consider not just the installed motor power but the actual power used in blending. Some mixers, such as the iconic Vrieco Nauta Conical Blender, only mix small portions at a time while the mixing arm rotates throughout the mass. These have very much lower power loads.

5.     Ease of Discharge
The discharge of a batch blender is one of the most critical functions. Here it is necessary to ensure that the blender empties fully and smoothly with no residual “heel” or bridging. Check the discharge opening size, as many blended powder products can have poor flow properties and can be a little sticky.

6.     Mixer Internal Finish
Smooth internal finishes to the mixer are usually best in most applications, as this aids discharge. In the food and pharmaceutical industries stainless steel vessels with an internal mirror finish are commonly used.

7.     Ease of Cleaning and Cross Contamination
This is very important particularly when one mixer is to be used for different products. If cleaning is highly critical, for example in the food and chemical field, then ‘cleaning in place’ (CIP) or even ‘sterilization in place (SIP) can be installed.

8.     Know your target result
It is important to know a clear end result specification so that equipment specialists can advise on the type of mixer best suited to your requirements.

9.     Factory Space
This is a fairly obvious point but it is something that needs to be considered carefully. It is not just the actual footprint of the mixer that you need to think about but any access requirements for loading, discharge, cleaning and maintenance. Height restrictions can often make the selection of a mixer a little more difficult.

10.             System Design
It is never too early to consider the design of the total system when making your mixer selection. For example, there would be no point in opting for high accuracy blending equipment if you are then planning on blowing discharged product a large distance across the factory thereby allowing it to disaggregate en route.

When selecting a mixer, it pays to talk to our experts to prevent costly mistakes impacting on subsequent stages of the process and final product quality. The Sales Managers at Perry Process Equipment Ltd can help you find the right specification mixer for your needs.
