Industrial blenders include any type of large blender used with industry. That being stated, the term includes many varieties of blenders used for different materials, degrees of mixing, and different end products. They are each used based on need for results and cost. It is important to note it is not all about cost.
Cone blenders are large silos with a cone end for bottom discharge. They are relatively inexpensive to buy but they only blend a smaller amount of material at a time so it is actually more expensive to use them.
In terms of pound of product blended and energy used, these are not as efficient but are still necessary.
These ribbon blenders are by far the most commonly used industrial blending machines. They are giant horizontal tubes with two counter-rotating ribbon blades on the inside, each shaped like a helix.
They efficiently and cost-effectively mix materials very well but not always completely like a rotary blender. They are used in chemical and food industries.
Rotary blenders are larger silo blenders that are unlike cone blenders. They are heavy-duty and costly with rotating blades that move at high speeds. There are different types but they all essentially use the same principle which is gravity and rotation mixing.
Rotary blenders are very efficient at mixing and used in a variety of applications.
All blenders are not created equally and one could say that you get what you pay for. Many are mass-produced in lesser quality for low prices. Some are built by steel manufacturers that can make virtually anything out of steel.
As it turns out, there is a special type of technology needed to make high quality industrial blenders. It is not all about cost or what can be made from steel.
