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

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

Selecting Wastewater Mixers for Wastewater Treatment – Part 1

Selecting Wastewater Mixers for Wastewater Treatment – Part 1 Wastewater Mixers for Optimal Chemical Preparation Chemical preparation in wastewater and water treatment directly impacts many downstream processes. Let’s take a look at several common chemicals used and some key factors that influence their preparation and the selection of wastewater mixers. Lime Slurry Preparation When preparing lime slurries for controlling pH, uniformity is critical. Why? Because lime solids must reach/stay in suspension if they are to serve their purpose in downstream processes. For this reason, it’s essential that wastewater and water treatment facilities have lime slurry mixers that can efficiently and effectively make up/maintain uniform slurries. In order to successfully suspend/re-suspend solids, a mixer needs to create a flow pattern that involves the entire

Selecting A Waste Water Mixer for Wastewater Treatment – Part 2

Selecting A Waste Water Mixer for Wastewater Treatment – Part 2 Waste Water Mixers for Optimal Flash Mixing & Flocculation In part 1 of this series on wastewater and water treatment mixers, we discussed how to select a waste water mixer for chemical preparation. In this post, we’ll show you how to select a Waste Water Mixer for flash mixing and flocculation. Done in a Flash? Aggressive Agitation + Speed for Flash Mixing Flash mixing is used to evenly distribute coagulating chemicals in water, allowing micro-flocs to form. As the precursor to flocculation, flash mixing increases the efficiency of flocculation and reduces chemical wastage. Because the components need to be quickly and evenly dispersed, this process is all about brute

Mixing 101: 4 Factors for Configuring Your Fluid Mixer

Mixing 101: 4 Factors for Configuring Your Fluid Mixer Considering Mixer Configuration If you’re in an industry that includes fluid mixing in its processes, you probably know that finding the right fluid mixer for your needs is critical to maintaining quality control, reducing costs, and optimizing efficiency. The key here is to engineer a fluid mixer that addresses the specific needs of your process. When configuring a mixer for your process, your mixing engineer should consider the following 4 factors: Factor #1 – Tank Type & Volume This determines the amount of fluid your tank can hold. This is important because it will determine the size and position of the fluid mixer and its mounting. Factor #2 – Viscosity This

Mixing 101: Flow Patterns & Impellers

Mixing 101: Flow Patterns & Impellers Mixing Flow Patterns & Impeller Types In our article on 4 Impeller Types and Their Applications, we provided an overview on the most common types of impellers used in industrial mixing. Now we’ll go into more detail about each impeller type and their influences on the mixing process. Our focus on impellers is due to the fact that they are the part of the mixer that does the actual mixing: as they rotate they create fluid flow. These flow patterns are the primary considerations when designing a mixer because creating the right flow pattern is critical to achieving the desired result. The most common flow patterns in mixing are axial (down and up) and
