Double planetary mixer delivers industrial mixing requirements

October 22, 2013

Any high-tech manufacturing firm in a commercial setting is not without a double planetary mixer. Undoubtedly, it produces the kind of mixing action that completes any batch production in a fast and efficient way.

Double planetary mixers have a dual-blade feature, with both blades rotating in their own axes. Apart from axis rotation, the blades also orbit the vessel on a single axis. Both blades move continuously along the vat’s periphery, detaching any substance from the walls of the vessel and bringing it to the interior.

After a single revolution, both blades of the dual planetary mixer will have passed onto the whole vessel. After only three revolutions, the substances inside the vessel have been mixed. After just 36 revolutions, both blades have completely contacted the entire batch.

Vital parts of double planetary mixer:

1. HV mixing blades

High-viscosity type mixing blades are perfect for use in ultra-high viscosity settings. The unique design of the blade promotes total mixing of all ingredients. It also removes the balling up tendency of substances that are being mixed.

2. Finger blades

The finger blade components are ideal for applications requiring the blending of delicate fibers and solids. The blades can be altered to optimize the benefit of its axial flow in the mix zone.

3. Sight / charge ports

Two 3-inch charge and sight parts are usually found in most planetary mixer types. This component allows viewing in one port and charging substances through the second port.

Included also as components of this mixer are combination sight and light ports; which are meant to have a convenient view of the mix batch, even while the mixer equipment is closed and in operation.

4. Mixer surface (exterior and interior)

Both exterior and interior surfaces of the double planetary mixer can be easily polished to assist. Thorough cleaning may be done between batches. Standard finishes are usually 80-grit, and mirror finishes are done if necessary.

5. Jackets

There are jackets available to be used for mix cans. These jackets can be had in specific designs, which include electric, double wall, and dimpled. There is an option for the jackets to be sheathed and insulated in order to avoid having the operator accidentally touching it while he is operating the planetary mixer.

6. Flush thermocouples

Flush thermocouples are meant to be mounted onto the side wall of the mixer’s vessel. This component allows the monitoring of the batch’s temperature at any time during the mixing cycle.

7. Control panels

The control panels of the mixer are custom-designed to meet the special requirements of every batch mix. The panel normally includes amperage, speed, timers, and temperature readouts. Also available are Full PLC controls.

8. Cove plug valves

Cove plug valve is supplied to mount on the bottom part of the mixing can. The valve allows connection to a cartridge or container-filling operation.

Put simply, double planetary mixers are designed to become a top option when it comes to low-to-high viscosity mixing and blending applications. Such equipment is ideal for any blending, whether wet or dry, without any regard to the flow characteristics of the product.
