Types of Pharmaceutical Blenders

There are many pharmaceutical blender types in the industry. Many of the blenders are similar in function with the significant difference coming with the design of the blender. At AmerEquip, we buy and sell a variety of pharmaceutical mixers and are well-acquainted with the various types of blenders in the marketplace. Let's take a look at these types of blenders. Do you need help selecting a pharmaceutical blender? We can help you choose the right blender for the right task.

V Cone Blender

A v cone blender has two mixing shells joined together at 70 to 90-degree angles, which form a V shape. Another name for a V cone blender is a twin shell blender. The purpose of the V-shape of the blender is to ease the movement of particles and easy blending. This is a blender that rotates on the horizontal axis, so the material particles fall and stumble on the mixture’s surface.

Many commonly use a v cone blender for mixing fragile solid-solid combinations, as well as precise measurements of powder and granules mixing and lubricating. It is easy to use, has a worm gear for controlling the speed, and processes a weight capacity of 20 kilograms to one ton per batch.

Double Cone Blender

A double cone blender is a tumbling blender with a double-cone-shaped shell in a diagonal position. The cone of this blender is fixed at a 90-degree angle to the cylindrical cone shell, which facilitates uniform combination. Every part of the blender, including the mixing tank and blades, are typically made of stainless steel. In general, the pharmaceutical double-cone blender has a gear box for adjusting the speed of the blender. On top of that, it often has a fireproof motor which helps to prevent an accident. One end of the cone has a butterfly valve for unloading the blended materials, while the other has a hole for loading.

The main use of a double cone blender is for the dry blending of less dense materials. This makes is a common blender for the cosmetic, food, chemical, and pharmaceutical industries. It effectively mixes dry powder and granules of different forms and sizes of homogeneous particles. When using it, there is an estimated mixing time of about 10 minutes at 20 to 100 revolutions per minute. Overall, it has a low risk of spillage due to the design of the cone, which makes it using it quick since cleanup is less.

Bin Blender

Bin blenders come in different shapes, which include rectangles, squares, or as V-shaped blenders. A bin blender also goes by the name of a free-fall or V blenders. This is a blender that has two opening valves. One of the openings is for loading materials and the other for unloading. Here are the applications of a bin blender in the pharmaceutical industry: lifting, rotary, lowering, clamping, and mixing actions.

Vertical Blender

Vertical blenders are in the "connective blender" category since they are used for blending and mixing dry granules and pellets. This blender is made of stainless steel with a narrow type and large diameter at the bottom. Ultimately resembling a cone-shaped vessel. A vertical blender can function effectively with just 10 percent of its blending capacity due to its design. And in the end, there is a complete discharge of the blended material.

Ribbon Blender

A ribbon blender is designed to achieve a triple mixing action and offers a light-duty low shear with a W or U-shaped horizontal trough with a rotating double helical ribbon agitator. You can use a ribbon blender for solids, liquids, and gas streams. You can also use it for mixing dry and pre-processed powder. It can be used for dry mixing solid lumps and processing large batches of wet mass. The general mixing time with this blender is about ten to fifteen minutes. A few of the more notable advantages of this type of blender include a belt-driven transmission power, wear, and corrosion resistance. Learn more about a ribbon blender.

Drum Blender

A drum blender is a tumbling blending machine that is shaped like a gallon-like drum. This blender has a fully enclosed shell, which is powered by electric motors. Yet, it does not need too much energy to run. There are no internal rotating parts in a drum blender, like impellers or blades, and the blending takes place through the up-and-down rotation of the drum. The loading and unloading of materials are through the same valve. Lastly, this type of blender lacks dead spots within the drum, enabling uniform blending and mixing. A drum blender is best utilized in efficiently mixing fragile and delicate materials, like powders.

Octagonal Blender

An octagonal blender is designed as, well, an octagon. The middle section of this blender is rectangle-shaped with the ends of the shell connected with firm strands. This blender is designed to accommodate a larger volume of materials while occupying less space than other types of blenders. The stainless-steel body is easy to clean and encases the materials fully to prevent spillage and contamination. When using this blender, you load the materials through the charging port at the top of the shell. When unloading, you use the butterfly valve. You work the pharmaceutical octagonal blender at a slower speed since it is used for a gentle mixing of dry granules.
