Multi shaft mixer – mixing viscous materials efficiently

A typical multi shaft mixer possesses a central-mounted and low-speed blade that efficiently sweeps the mixing vessel wall. It has extra high speed shafts that may be used when necessary. The blade that’s fast moving is able to provide much-needed high shear to dissolve, disperse, and mix ingredients. On the other hand, low speed blades feed the high speed ones by mixing and folding the mixture within the vessel. It is also tasked to scrape the vessel wall, thereby improving the uniformity and consistency of the material. Multi-shaft types are often utilized to blend medium to highly viscous products.

High speed disperser, when working on its own, can only perform in a limited way with viscous products, which is why low speed blades must be included to obtain a homogeneous mixture. If the tool is equipped with a scraper, low speed blades help immensely in the transfer of heat onto the exterior jacket. Multi-shaft types of mixers are also used with less viscous products, especially when performing vessel wall scraping.

As in many other mixer types, multi shafts are applicable in many fields as well; such as the production of printing inks, caulks, sealants, media slurry, hot melting adhesives, toothpastes, lotions, and creams, among others.

Features of multi-shaft mixer

1. The tool varies in sizes, from small lab unit to equipment that can accommodate as many as 3000 gallons of materials.

2. It has an inverter-driven motor, with a configuration that’s tank or hoist mounted.

3. It is constructed out of carbon or stainless steel materials, and boasts of super-polished finish.

4. Multi-shaft type also has a helical feature that assures sufficient circulation and enhanced temperature control.

5. Low and high speed blades are available, depending on application.

6. Operation can be done in a number of ways; namely, pressurized, vacuum, and atmospheric operation.

6. Multi shaft makes use of an advanced built up inverter.

Different Models of multi shaft mixing equipment

1. Dual shaft

This type utilizes central, low speed shaft in combination with high speed shaft. Its configuration handles multi-shaft mixing tasks. Because of its separate blending shafts, cleaning and maintenance is much easier and more convenient.

2. Triple shaft

This version is basically similar to the dual type but will added offset high speed shaft found at the low speed shaft’s opposite side. The second shaft offers added shear work also reduces processing time. The third shift is in the form of a rotor stator, providing mechanical and hydraulic shears tasked to disintegrate a solid into liquid. Triple shaft is also ideal in performing emulsification.

3. Concentric

Concentric multi shaft mixer types are able to incorporate central-mounted and low speed hollow shaft, which likewise allows the mounting of the high speed shaft within the mixture’s center. The advantage of the concentric design is that its blades are much bigger than the offset high-speed type. While experts may contend that the large blade of concentric shaft mixer means consumption of greater horsepower, others insist that it is able to deliver more quality work at a lesser time.
