Mixing and Blending

Catalytic slurries consisting of solid catalysts and support materials suspended in a liquid medium are commonly prepared in batch tanks agitated by low-speed mixers such as propellers, anchor paddles and pitched blade impellers. These devices can sometimes suffer from long cycle times and inadequate dispersion especially in large batches. Technologies like the Ross Solids/Liquid Injection Manifold (SLIM) offer a more practical method of wetting out powders and quickly achieving the desired particle size distribution in high percent solids slurries.

Polyvinyl alcohol (PVOH, also referred to as PVA) is a versatile polymer that plays multiple roles in the manufacture of adhesives, sealants, cosmetics, paper, textiles and many other products. This paper describes the benefits of preparing PVOH solutions in a well-designed Multi-Shaft Mixer capable of bulk agitation, high shear deagglomeration, and superior heat transfer.

Herbicides and insecticides in gel form enable easy, accurate and controlled application for increased efficacy and safety. Compared to traditional pesticides that are sprayed or sprinkled, gel formulations are smeared onto targeted surfaces which reduces the risk of chemical runoff and contamination.

A global cosmetic company with the goal of expanding their gel manufacturing capabilities found a solutions with the 100-gallon VersaMix Multi-Shaft Mixer.

Multi-shaft mixers are versatile systems used in the production of food, beverage, pharmaceutical and medical products. This bulletin discusses a few equipment features commonly supplied on multi-shaft mixers intended for sanitary applications.

This white paper presents some ideas for selecting the right inline high shear mixer for your process based on a company’s collective experience as a mixing equipment provider to process industries.

Mixer testing simulation trials are needed to confirm the suitability of a specific mixing strategy. This white paper explores five ways to increase energy efficiency in new and existing mixing processes.

Mixing is one of the most common operations in food processing, but comes with challenges -- batch-to-batch uniformity, optimizing blend times, and most importantly: improving cleanliness.

Mixing processes vary from one application to another and there are no fix-all solutions.This white paper presents some strategies for improving commonly encountered batch mixing problems.

Uniformly dispersing powders into a liquid batch in a practical amount of time is a common problem for F&B manufacturers. This white paper explores five tips for dispersing powders more efficiently.

This paper provides practical information on the efficient use of specialty mixing equipment for the preparation of low, medium and high viscosity solid-liquid mixtures under low and high shear conditions.

When selecting mixing systems, foresight for scale-up is important for long-term success. A quick shift between systems can be the difference between economical success and a financial disaster.

Mixing challenges throughout the process industries are heightened as the viscosity and complexity of the mixture rises. This webinar reviews the numerous options that are available to help select the most efficient mixer for a users requirements.

Dry blenders are typically described as being of horizontal, vertical or tumbling designs. On the surface it would seem that each can be used for the same application, but subtle differences usually make one preferable over another. This webinar helps to narrow the choice of the unit for a particular production requirement.
