What Is Flowable Fill? A Complete Guide to Controlled Low Strength Material

Uncategorized / Sturtevant

Flowable fill, also known as controlled low strength material (CLSM), is a self-compacting, cementitious material used primarily as a backfill or void-fill alternative to traditional compacted soil. It is designed to be placed without mechanical compaction, making it ideal for hard-to-reach areas or time-sensitive construction projects. Once set, it forms a stable, low-strength mass that

The Importance of Protein in Aquaculture Feed

Uncategorized / Sturtevant

In the aquaculture industry, feed accounts for a significant portion of production costs, typically ranging from 40-50%. Given that fish have protein requirements varying from 18-50%, the role of protein in their feed is crucial. These protein needs differ by species; for example, tilapia, one of the most commonly farmed fish, requires 32-38% protein in

The Business of Particle Size Distribution

Particle Size Reduction / Sturtevant

To be successful in the business of material size reduction, achieving a certain particle size and/or shape is key. In order to determine that, you have to measure particle size distribution (PSD)…but what does that mean? PSD is a method of determining the size characteristics of particles. There are multiple ways to make that determination.

How Wheat Starch Can Fit Into a Gluten Free Diet

Particle Size Reduction / Sturtevant

Gluten is a protein found in wheat, rye, and barley—so it might be easy to assume that wheat starch isn’t compatible with a gluten free diet. Fortunately, that doesn’t have to be true. For over a decade, wheat starch products specifically designed to have gluten removed have been labeled as gluten free in Europe, but

Redefining Lithium Carbonate Roll Compaction

Particle Size Reduction / Sturtevant

As is the case with many raw materials, lithium carbonate micronizing can be made more efficient by densifying the finely sized powders into granules. The industry-leading K.R. Komarek Roll Compactor, which takes the finely sized powders and compresses them into a solid shape for more efficient processing, has become the industry standard for lithium carbonate
