Tumble Blenders, Dryers, and Formulators

The General Machine Company of New Jersey (a name later shortened to GEMCO) invented the tumble blender in the 1930s as a safer method to blend 
 gunpowder.  Many innovations followed, including internal agitators, sperical disc valves, jacketed vessels to create dryers, airless spray for liquid addtion, slant cone vessels for better, faster blends, and many more.

Why Choose a Tumble Blender?

1. Speed – Blending times can be up to 10X faster than other mixers.
   
2. Gentle – The powder is not subject to shear action from paddles, augers or  screws.
   
3. Proven – Over 90 years of blending applications with repeatable, ultra low  standard deviations.
   
4. Dependable – The simple mechanical design reduces the number of moving parts resulting in fewer things that can go wrong.
   
5. Predictable – The blending process is repeatable so you always know how long it will take to get the results you need.
   
6. Sanitary – No nuts, bolts, paddles, augers or screws to sanitize.
   
7. Easy In / Easy Out – Connections for any type of loading are easily adapted, controlled and monitored.  Powder pack out is fast because it is gravity fed,
   not  slowly pushed out.
   
8. Low-Cost – Some mixers cost up to 5X more than a tumble.
   
9. Green – Energy consumption is up to 75% less than other mixers.
