Barrel Mixer

The need for different types and styles of mixing in a drum can be found throughout the chemical, paint and coating industry. An agitator can mix liquids and solids inside of a metal container.

Since there are many ways to mix fluids in a drum, it is important to get familiar with the different methods that can be used and the different types of Barrel Mixers that exist.

What is a barrel mixer?

- A machine used to blend or mix chemicals together in a container (usually metal) called a drum.

How to Choose a Barrel Mixer: 3 Methods for Mixing in Drums Supplying the right method to mix chemicals in a drum is important because it can affect efficiency, safety and production.

Barrel Mixer Types

- Spiral mixer: uses a helix spiral blade wrapped around the inside of the drum, slow slow mixing action but easy to clean.

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

- Direct drive mixers are attached to the shaft of the drum to mix the chemical within the drum.

Other Things to Consider Before Purchasing a Barrel Mixer

- Power requirement for optimum performance

- Equipment total height

- Volume capacity of container being used

Bung mixing in drums is a method to mix materials inside a drum, as well. They aren't very efficient, can run at high speeds and can cause temperature problems. These mixers run at high speeds and quite often run a high shear rate due to high speed. They usually have a small, ineffective blade that turns the material.

Even if one replaces the bung mixer with an agitator, the material will still rotate at a high speed. It is important to slow down the process of mixing by using weight loads or chills.

What are other ways to mix in drums?

- Multi cone Mixers use multiple cones stacked on top of each other. The multi cone agitator works by rotating the container and having a spiral-shaped mixing screw rotate inside of a few cones to blend chemicals together.

End Cap Mixers have a mixing screw that allows chemicals to be mixed from the center of the barrel.

Side Press Mixeris designed for use in cylindrical drums. It has a side pressing fitting rather than a bung. This allows for a positive seal, and is easily attached to a mixer shaft.

Pallet Mixer is similar to an end cap activator, but uses paddles instead. The positive seal is needed for drum bungs to prevent leakage.

Direct drive mixers have the shaft connecting the mixer to the drum's rotating axle. This can reduce vibrations in the system.

The vibratory barrel mixer can be used to mix paint, liquid chemicals and other dry materials together. This type of drum mixer uses a rotating mixer, an eccentric weight and a coupling device to reduce any vibration transferring to the drum.
