A ribbon blender is generally proficient at dealing with powders and bulk solids. It is a versatile mixing device that is scalable too. It is why so many industries use ribbon blenders for the purposes of blending dry powders, pellets, granules and other similar items.
Most people think of a restaurant, smoothie shop or a home kitchen when they picture a blender. But ribbon blenders have a prominent role in industries because they are so versatile.
Choosing a Ribbon Blender
Finding the right type of ribbon blender for a purpose is very important. There are a few different options, depending on the use case. Here are some of the choices that you may need to make when selecting a ribbon blender for an industrial purpose.
Standard Duty vs. Heavy Duty
A standard duty ribbon blender will be able to handle a bulk density of around 35 pounds per cubic foot. If the batch size is going to have a greater bulk density, then it may be necessary to get a heavy duty blender to complete the job.
When there is a doubt, it is better to go with the heavy duty model. Even if it is not being used to its full potential, it is better to have the heavy duty model for the few instances where the bulk density is greater than what a standard ribbon blender can handle.
Belt Drive vs. Direct Drive
A belt drive is common among traditional and older ribbon blenders, where the flexible belts and pulleys ensure the proper speed and torque is achieved. But many modern ribbon blenders have started going in the direction of a direct drive, where a gearmotor is used. These direct drive blenders have a very high dynamic capacity, which is great for mixing operations that require a lot of start/stop activity.
