  • select a planetary disperser mixer,
  • specify specific needs with a manufacturer, and
  • justify your capital expenditure.

Where are Planetary Disperser Mixers Today?

 

In the past, if you want to choose a mixer, you would simply look into a standardized chart where you will match up the mixer capacity, agitator power, disperser power and tip speed to the properties of your material.

Of course this method does not give a hundred percent solution for all mixer problems. Emerging mixer manufacturing companies have been in a tight competition on bringing the best mixers in the market to solve all mixing issues with lesser footprint.

Because of this, newer and more enhanced mixer designs have been released that gives the most accurate configuration, blading design and gearing system to produce the optimum product properties for the cosmetic, pharmaceutical and food industries.

Today, manufacturers can produce an industrial planetary disperser mixer that combines all the features you need. This has paved a way to an effective processing method that gives better flow, optimum shear and effective heat transfer.

Testing Your Materials and Being Accurate with Rheological Properties

Prior to purchasing a mixer, you must first know the characteristics of your materials and test it in the industrial mixer manufactufacturer’s lab scale mixers.

Typically, they will use a prototype or a lab mixer which is a representation of the industrial planetary disperser mixer. Under simulation, you and the manufacturer can be able to investigate if the mixer adapts to your materials’ requirements.

Furthermore, both sides can be able to determine the proper specifications of the planetary disperser mixer; What type of agitator blade does it need? Does it need hydraulics? Is vacuum needed?

Knowing the Capabilities of Planetary Disperser Mixers

 

Take this scenario:extremely viscous materials being processed using a multi-shaft agitator, or worse, a traditional agitator. While mixing, there comes a point where the ingredients no longer have the ability to flow. This can be attributed to the thickeners or additives or thick powders being mixed. The surface of the mixture would just be continuously carved by the impeller.

Meanwhile, heat builds up around the disperser and homogenizer assemblies. For this case, a planetary mixer may be more suitable for use.

The Solution:

In a Planetary Disperser Mixer, the impeller does not only move in one axis shaft, but rather, around the entire mixing vessel. The agitator built with rectangular blades passes in each part of the batch and not just around the periphery. This is an effective way of processing high viscous products, such as in processing gummy or sticky components.

Ginhong’s planetary disperser mixers provides powerful kneading and mixing action regardless of the product’s flow characteristics. Thus, a planetary mixer is the best solution for highly viscous products.

Specifying the Right Planetary Mixer for Your Application

To know which type of Planetary Mixer is the best for your application, you should be able to consider the following.

1. What is your material?

Planetary disperser mixers are used in mixing materials which are over 1,000,000 cps in viscosity. These products are especially thick and needs more advanced mixing blades and accessories. Large, viscous material batches can be processed at a lesser time and cost-effective way with planetary mixers.

Planetary Mixers are typically used for the production of:

  • Abrasives
  • Battery Pastes
  • Bone Graft Substitutes
  • Caulks
  • Cement pastes
  • Coatings
  • Conductive Inks
  • Dental Compounds
  • Dilatant Materials
  • Fiber Dispersions
  • Filled Epoxies
  • Filler compounds
  • Heat Sink Compounds
  • Highly filled formulations such as soy-based adhesives
  • Hot melt adhesives
  • Lightweight Composites
  • Lubricants
  • Magnetic media slurry
  • Medical Pastes
  • Metal Powders
  • Molding Compounds
  • Pharmaceutical Gels
  • Plastics Compounds
  • Refractory Cements
  • Sealants
  • Sealants and adhesives
  • Solder pastes
  • Syntactic Foams
  • Thermal greases
  • Toothpaste
  • Urethane sealants
  • Viscous and concentrated creams and lotions

 

Industries served by Ginhong Planetary Mixer includes:

  • Paint and lacquer industry
  • Adhesive and sealant industry
  • Building chemicals industry
  • Chemical industry
  • Pharmaceutical industry
  • Food industry

2. What is your production volume a day?

If you know your production volume a day, you would know the capacity of the mixing vessel you need for planetary disperser mixer. Furthermore, you can specify if you need one or more equipment for your manufacturing plant.

Again, take this example:

You need to produce 300,000 to 320,000 bottles of 300 mL Urethane sealants per day. Your plant would operate for 16 hours a day (2 shifts, 8 hours per shift). 

  • Mixing time + residence time for silicone sealant for this scenario is 10 min/batch.

Sizing your mixer capacity:

No. of bottles per hour =320,000 bottles/hr16 hours= 20,000 bottles/hr

Volume per hour = 20,000 bottles/hr x 0.3L/bottle = 6,000 L/hr = 100 L/min

Volume per batch = 100 L/min x 10 min/batch = 1,000 L/batch

Choosing a mixer:

  • One (1) – 1000 L Planetary Disperser Mixer

Of course, you would have to consider other factors such as machine efficiency, probability of downtimes, duration of mixing and material transport and supply. We presented this scenario as an example but the whole process of sizing your planetary mixer depends on many factors.

3. Do you need a customized planetary mixer?

Ginhong is ready to customize your planetary mixer according to what your product needs. We have been dealing with multiple customization for customers for a long time. Determination of what needs to be done for your product can be determined by test results from our lab mixers.

Special installations can be accomodated to perform specific tasks such as extra heating, cooling or milling operations.

There are also cases that our clients requests for customized control panels. Other times, customers only want a heating phase tank without the water phase. We also get a lot of requests for size and shape customization.

4. Sealing the deal: How much would it cost you?

Planetary mixers are anywhere between 4-6 figures internationally speaking. When you deal with a China industrial mixer manufacturer, you can expect a lower investment without sacrificing the quality of the planetary mixer.

Planetary Mixer Configuration Options

One of the advantages of picking Ginhong as your Planetary Disperser Mixer supplier is you can choose from a variety of well-engineered and intricately designed mixer mounting assemblies and modules. Each of the mixing units are manufactured to cater varying mixing needs and processes.

Planetary Disperser Mixer

The Planetary disperser Mixer is a special type of planetary mixer combining an anchor blade and a shaft containing two disperser blades. Both rotate on separate axes while revolving around the tank.

The anchor blade continuously directs materials in the central area, where the high speed rotation of the disperser shears the materials. In effect, it completely mixes and homogenizes thick, viscous ingredients leaving no dead zones or unmixed portions. Thus, a Planetary Disperser Mixer eliminates multi-stage processes by combining two impellers in one equipment.

Double Planetary Mixer

A Double Planetary Mixer is a complete mixing equipment commonly used in manufacturing adhesives. Typical configuration consists of three mixing technologies: a rectangular blade, an HV blade or a finger blade and a two-blade disperser shaft.

The best part in using this enhanced planetary disperser mixer is it has a unique mixing movement that eliminates the climbing problem of materials, especially adhesives and extremely viscous pastes. Thanks to the sweeping spiral effect created by the HV blade, the material is conveyed effectively up and down the mixing vessel. The rectangular blade further cuts down agglomerates and blends the mixture, while the disperser facilitates easy dispersion and homogenization.

Discharge System

Hydraulic Ram discharge press are designed to remove non-flowable ingredients such as high viscosity materials from removable vessels of industrial planetary mixers and multi-shaft mixers. It is designed with a discharge pressure of 90 PSI up to 227 PSI depending on the difficulty of the material to be removed.

Hydraulic ram discharge press consist of a pressure plate mounted to a hydraulic ram, supported by a structural steel frame. The pressure plate closely fits the inner diameter of the mixing vessel, and, with the help of a special O-ring seal, forces the product through the discharge outlet in the bottom of the mixing vessel.

Thanks to this equipment, you can achieve a high product yield above 98%.

Construction of Planetary Mixers

What makes a well-engineered and high quality planetary disperser mixer and double planetary mixer?

Materials

The best planetary mixer comes with a stainless steel material and all the parts are compliant with cGMP regulations. Stainless steel has a high strength-to-weight ratio that makes it light for its strength capability. It’s also notable for being resistive to corrosion so highly acidic ingredients will not affect the properties of the metal.

Stainless steel planetary dispersers are recommended for clean operation. Other material options such as iron simply cannot compete with the overwhelming advantages of stainless steel. For highly abrasive ingredients, Ginhong adds a wear-protective coating on the tank and contact parts to further enhance its resistance.

Blade Options

Ginhong offers planetary anchor blade options, each manufactured for specific purposes.

RECTANGULAR BLADES

This type of mixer blade is used for suitable for dry and wet mixing for low to high viscosity products.

HV – BLADES

The HV-Blade is for medium to high viscosity products (6 million cps).

 

This blade design has an angled helical configuration that yields down-thrust action.

FINGER BLADES

 

Used for delicate products such as fibers.

Fluid Viscosity

Abrasives and paper slurries are highly viscous products by nature and cannot be easily dispersed and homogenized. That is why fluid viscosity is an essential parameter to take note of when selecting the right type of mixer. Behavioral fluids perform differently when you mix it.

Some fluids would thicken as you mix, while others remain at the same viscosity. You need to determine the behavior of the fluid you will use.

Here are some of the most common kinds of liquids you may use with a planetary mixer.

Pseudoplastic Liquids: increase in shear rate, viscosity also increases. Some examples would include latex, paints and gels.

Dilatant Liquids: Increase in shear rate increases viscosity of dilatant liquids. Candies, slurries and clays are examples of dilatant liquids.

Thixotropic Liquids: This type of liquid decreases in viscosity as you agitate it. Some examples include peanut butter and tars.

Mixer Drive

A variety of drive systems are available for both the Double Planetary and the Planetary Disperser Mixer. Electric drives are standard. Electronic variable speed control is a popular option, because it enables you to start the mixer under heavy load and fine-tune the mixing process. Ginhong can also provide hydraulic drives for planetary mixers in any size.

Popular Planetary Mixer Option Packages

Vacuum and Heating and Cooling System

Vacuum construction and the jacketed mixing tank allows you to mix at the temperature you want and cool heat-sensitive products gently and quickly. The Double Planetary Mixer includes a heavy-duty frame, precision machined gears, extra durable bearings, and an all stainless steel gearbox.

Lifting System

The hydraulic lift system not only provides lifting ability to the planetary mixer but also provides compressing power to discharge the finished product from the portable mix tank.

Electrical Control Panel

Ginhong’s Mixers are all equipped with an electrical control panel which provides graphic man-machine interaction. They design and develop these panels using high-grade material in compliance with industry standards.

Ginhong offers a complete line of control systems that are pre-programmed/pre-wired for turn-key start-up and long-term flexibility. Our new streamlined, built-in designs reduce cabling while they simplify maintenance. Routine operation is also simplified.

Calculating ROI on CapEx– How long will it take for your planetary disperser mixer investment to pay for itself?

Calculating the Return on Investment from capital expenditure lets you forecast how long it’s going to take for your investment to pay off. Here are five steps to calculate your ROI.

  1. Ask the planetary mixer manufacturer for a quotation and add up equipment acquisition costs. Your list may include:
  • Mixer price
  • Freight costs
  • Commissioning and installation costs
  • Training costs
  • Cost of financing
  • Annual maintenance and parts expenses
  1. Think carefully and add miscellaneous fees and additional costs that you think would need to be regarded. You may involve your financial advisor in the matter. The cost may include tax incentives when you purchase your mixing equipment, etc.
  2. Include rental program fees if applicable when you rent the equipment for a month or two.
  3. Calculate ROI.

Calculate the Payback Period (PBB) Formula

This determines how much time it will take to recoup the initial investment.

Payback period=Total new equipment costTotal Periodic benefit realized from new equipment

For example, a planetary disperser mixer costs $3,000 and a cosmetic company has a net annual benefit of $2,500

Payback period=$3,000$2,500= 0.5 years or half a year

Calculate the Simple ROI

ROI is the ratio of a benefit or loss made in a fiscal year expressed in terms of an investment and shown as a percentage.

Return of Investment (ROI)=Net Benefit or loss generated by new mixer equipmentTotal new equipment cost

Using the same example as above, if you are purchasing a planetary mixer for $3,000 and forecast a net annual benefit of $2,500 (reduced energy consumption, eliminating additional deaeration units, shorter mixing cycle, heating time, or discharge time, smaller footprint, etc), your return on investment will be:

Return of Investment (ROI)=$2,500$3,000x 100 = 83.33%
