mixing in drums

The need for different types and styles of mixing in a drum can be found throughout the chemical, paint and coating industry. For these applications, an agitator is able to mix solid materials or liquids together inside of a metal container.

There are many ways to stir fluids in drums, so it is important that you become familiar with all the options and types of drum agitators.

What is a Drum Agitator?

- A machine that mixes chemicals in a container (usually metal), called a drum.

How to choose a Drum Agitator: Three Methods to Mix Chemicals in Drums. This is because it can impact efficiency, safety, and production.

Types of Drum Mixers

- Spiral mixer: A spiral blade wraps around the drum to slow down mixing, but is easy to clean.

- End cap agitators: create a torque movement on the drum for thorough mixing.

- Direct drive agitators: are attached to the drum's shaft to directly mix the chemical inside the drum.

Other Things to Consider Before Purchasing a Drum Agitator

- Maximum performance requires power

- Equipment total height

- Volume capacity of container being used

Bung mixing is used to mix materials within drums. However, they are not very effective, run at high speeds, and cause temperature issues. These mixers operate at high speeds, and often have a high shear rate because of their high speed. Typically they have a tiny and ineffective blade on them that turns the material.

Even if one replaces the bung mixer with an agitator, the material will still rotate at a high speed. This means that it is still essential to slow down the mixing process by using weight loads and chills.

What are other ways to mix in drums?

- Multi cone Agitators use multiple cones stacked on top of each other. Multi cone Agitators work by rotating the container, and then having a spiral-shaped mixing shaft rotate within a few cones to mix chemicals.

End Cap Agitators use an adjustable mixing screw to allow the chemicals to flow from the center of the barrel.

Side Press Agitator is designed for use in cylindrical drums. It uses a side press fitting rather than a bung. This allows for a positive seal, and can be attached easily with a mixer shaft.

- Pallet Agitator works similarly to an end cap agitator but has paddles instead of a mixing screw. The positive seal is needed for drum bungs to prevent leakage.

- Direct drive agitators have the shaft that attaches the mixer directly attached to the drum's rotating axis, which can be helpful in reducing the amount of vibration there is in the system.

- Vibratory Drum Mixer can be used for mixing paint or other liquid chemicals together, rather than dry materials. This type of drum mixer uses a rotating agitator, an eccentric weight and a coupling device to reduce any vibration transferring to the drum.
