“A Simpson Mix-Muller (model 6-G) was installed as a mixer for the new mineral line because our research department had indicated that this Simpson does the best job mixing mineral type ingredients. Over several years that department has investigated and observed four or five other kinds of mixers in actual operation. They also considered the remarkable performance of two other Simpson mixers in our main plant.” said Production Foreman, Jack R. Gower.

“These two mixers,” injected production manager of the mineral department, “are the best darn mixers you can buy. Both are #3 Simpson Intensive Mixers – one has been running since 1944, the other since 1946, that is to say, 26 and 25 years. And mind you, to keep up with production demands, they often had to go around the clock… particularly during the last eight or ten months! And they go 6 days a week.”

“I think Simpson builds the only mixer with enough strength and mixing action for our minerals, especially those made into blocks, which are loaded with heavy binding agents.”

“Maintenance is equally important in running a plant efficiently. But no maintenance program can ever be better than the equipment itself. All we have ever done to these mixers is purely routine: lube once a day, replace plows once a year, liners every two years. Even after running for a quarter of a century we have never had to work on their gear boxes! And if we didn’t think they would continue to perform like new, we wouldn’t be putting them into the new mineral lines!”

Gower then amplified: “When you mix solids and binding liquids into a uniformly blended product, you’ve got a heat problem. The binding agents (petrolatum) can ball up under excessive heat, and you can come up using to much… or end up with an inconsistent product: poor quality. Also, the vitamin A, which is added to our mineral mixes, is encapsulated and can easily be destroyed by heat. Many mixers capable of doing a good job with other materials fail here. But no problems with Simpsons.”

“In spite of lower temperature build-up, the Simpson mixers disperse the particles, both liquids and solids alike, quickly and evenly. This results in short mixing cycles of 8 or 9 minutes. With other mixers we might have to increase that time or use larger sizes… I can’t really tell, because for 25 years we haven’t used anything but Simpson mixers for our mineral lines.”

You might say that mixing is the starting point of all products we manufacture. Either all (the finished minerals) or parts (base minerals) of our finished products must pass through one of the three Simpson mixers. Therefore it is safe to state that the Simpson mullers are vital components in meeting the strict Q.C. requirements enforced by our Q.C. and research departments.”
