Mixing 101: Low rpm, High Torque Mixing

Mixing 101: Low rpm, High Torque Mixing In the process industry, there’s a strong focus on power as the defining characteristic in mixing. Many considerations are often left by the wayside when choosing a mixer. These factors can make or break the application. Relying solely on the G-Value or velocity gradient in mixer design leaves important information out of the equation. Focusing on the G-Value gives rise to the misconception that horsepower, rather than torque, is the critical factor determining mixing effectiveness. This method is effective for applications requiring high-sheer and turbulent flow, but this isn’t always the case. High-speed mixing introduces a host of additional considerations based on fluid viscosity, flow patterns, and shearing. Mixing Categories Different types of

Side Entry Mixer or Top Entry Mixer – Always Consider the Costs!

Side entry mixers and top entry mixers play an important role in a diverse number of industries such as mining and natural resources, food processing, agricultural chemicals, oil and gas, wastewater treatment, food manufacturing, pulp and paper, brewing and distilling, paints and coatings, inks and dyes… In every industry, engineers, consultants and operations managers need to carefully assess their unique requirements and environments, then look at the short- and long-term impact on everything from product quality and operating costs to the bottom line before committing to a mixer. For many decision-makers, side entry mixers have been the most visible option thanks in part to side-entry and submersible suppliers’ ongoing marketing efforts. While Dynamix provides a full range of side-entry mixers,

Mixing 101: Optimal Tank Design

UNDERSTANDING HOW TANK DESIGN AFFECTS MIXING Apart from the actual mixer, the design of the mixing tank is the single most important factor in producing a successful result in any process. In order to allow optimal performance from a mixer’s impeller, it is essential to create an environment that supports both correct impeller positioning and appropriate liquid coverage of the impeller. Incorrect positioning negatively affects the performance of a mixer, the quality of a product, and may even be detrimental to the performance life of the mixer drive. When looking at tank designs, vertical cylindrical, and square or rectangular tanks are most common. In the process of selecting the optimal tank design for an application there are certain rules of

Mixing 101: Baffled by Baffles?

Mixing 101: Baffled by Baffles? How Baffle Configuration Can Optimize Industrial Mixing In our previous posting on configuring your mixer, we learned that the tank type and volume, viscosity, specific gravity and the process are key factors the mixing process. In this article, we dive into how baffle configuration and mixer mounting can prevent the undesirable flow pattern of swirling. Let’s look at a common tank configuration: an un-baffled cylindrical tank. If a mixer is center-mounted in this tank, what we see is a very inefficient flow pattern: the tangential velocities coming from the impeller cause the entire fluid mass to spin (Fig. 1).  Basically, the entire fluid (and its solids) moves like a merry-go-round. In solid suspension applications, the solid
