There are all types of blenders, from home blenders all the way to industrial blenders. Of course, different types are used for different tasks. When it comes to mixing powders and other solids in an industrial setting, the most commonly used type of blender is called a ribbon blender. Here is what one needs to know before purchasing such a blender from a vendor.
Before requesting a price, the bulk density of the product that is being mixed should be known. This information should be as accurate as possible. While the size of the weight is usually measured by weight, the blender is actually measured by volume capacities. Thus, the bulk volume of the product should determine exactly what model of blender is purchased versus the actual weight of the product batch.
There are a few other things that bulk volume determines when it comes to purchasing ribbon blenders. These would be the horsepower of the motor for the appliance and the whether the model purchased should be a standard model or a heavy-duty model. A standard model is defined as that which can blend a product density of 35 lb per cubic foot. Heavy-duty blenders are any blenders which can mix in excess of that. Remember that when purchasing a blender of this type, the optimal mix ratio is at least 30 to 40 percent of the maximum volumetric capacity.
Another factor to consider when purchasing ribbon blenders is the type of drive it will use. There will be a choice between a belt drive and a direct drive. The belt drive is found on older models as this is what was traditionally used before the invention of the direct drive. The belt drive consists of several flexible belts along with pulleys that help to achieve the torque and speed needed to function properly.
If the machine is more modern, it will have a direct drive. This drive is preferred over older belt-driven models as they are specifically matches to the requirements the blender will be facing. It is a solid motor and therefore far more durable than its belt-driven cousin.
No matter which blender is chosen, as long as it is ribbon-blade oriented, it will definitely be the best choice for the mixing job at hand.
