The invention of the wheel led to the world being as it is today. Or one can perhaps say that the wheel was invented because the world is as it is today. Of course, some facts must be revised – the world was quite different back in those prehistoric times, but it cannot be denied that we as a species have not changed in nature. We always want more, we think more, and we can design and invent more than our coexisting species. We have a keen sense of the particular need that must be fulfilled, and minds that enable us to analyze our surroundings for what is available to fashion into a product of our choice.
Industrial mixing machine has become quite a commonly marketed commodity today, which means that no one actually stops to give a thought to the genius of the invention that it is. It basically enables us to exist in a world where we can make full use of products such as toothpaste, shampoo, creams, ointments, vaccines, butter, beverages, shoe polish, powders, plastics, and many more items on that list that we have also taken for granted.
These products are better known as emulsions or colloids or simply as mixes. What distinguishes them from a simple solution is that they consist of substances that do not dissolve in one another and cannot be used in a dissolved state in some other liquid. They also differ from chemical compounds in that the participating ingredients do not react with each other, and are retained as such in the final mix, the only difference being that they are now blended together, their particles broken down into infinitesimally fine pieces and thrown around in a tank and extremely high speeds till they form a homogeneous mix or suspended state material.
It is not easy to mix any such materials. While the principle is fairly simple, translating it into an actual laboratory setup requires much more consideration. Very high speeds are required for the particles, which means that an agitator must be present to generate adequate centrifugal force within the mixing tank. The tank itself must stay steady throughout this, or else the purpose of the agitation will be defeated. Extremely high temperatures are obtained, and care must be taken to ensure the safety of the workers and of the equipment. The mixing machine is an industrial giant born from a simple idea – further proof that the wheel is invented every day.
