Barrel Mixer

Chemical, paint, and coating industries require different methods of mixing drums. An agitator can mix liquids and solids inside of a metal container. 

 

There are many ways to mix fluids inside a drum. It is important to be familiar with these methods and the various types of barrel mixers. 

 What is a barrel mixer?

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

 How to choose a barrel mixer: Three methods for mixing chemicals in drums. This is because it can impact efficiency, safety, and production. 

Barrel Mixer Types 

- Spiral mixer: A spiral blade wraps around the inside drum. It is slow and slow, but it's easy to clean. 

End cap agitators: Create a torque movement on your drum to mix thoroughly 

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

There are other things to consider before purchasing a barrel mixer 

- Maximum performance requires power 

- Equipment total height 

- Container volume to be used 

Bung mixing is used to mix materials within drums. They aren't very efficient, can run at high speeds and can cause temperature problems. These mixers operate at high speeds, and often have a high shear rate because of their high speed. They usually have a small, ineffective blade that turns the material. 

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

Are there other ways to mix drums? 

Multi-cone Mixers are made up of multiple cones that have been stacked on top. Multi cone agitators work by rotating the container, and having a spiral-shaped mixing shaft rotate within a few cones in order to mix chemicals. 

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. Drum bungs must have a positive seal to prevent any 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 drum mixer is made up of a rotating mixer, an eccentricweight and a coupling device that reduce vibration transfer to the drum.
