About Trigg Engineering

R. Darrell Trigg, P.E.

I was previously the General Manager and Chief Engineer for Short Mountain Silica (SMS) (Shortmtnsilica.com) forĀ  25 years. I helped build this company from it’s very beginnings to it now being the seventh largest industrial sand (silica sand) supplier in the nation. Amongst other projects, I installed four 800 horsepower ball mills to produce silica flour, along with four 1200 ton silos, and the remainder of the plant. I also installed a 200 ton per hour fluidized – bed sand dryer. My last project with them was the installation of an entire plant to make frac sand for the natural gas industry. In several of these plants, I installed different types of dust collecting systems. I also have experience with coal, ultra-high purity quartz, feldspar, mica, and other minerals.

I now have a professional engineering consulting firm in Rogersville, TN. I’m a licensed professional engineer with a bachelors and masters degree in Mining and Mineral Processing Engineering from Virginia Tech. As with Short Mountain Silica, I can take a need that a customer has and do a complete job of designing, engineering, and installation. Please let me know if I may ever be of assistance to you.

I am the author of a book : “Developing A More Effective Prayer Life – A Practical Approach “. This book was published by the tenth largest publisher in the nation, Tate Publishing in Oklahoma. You can find the book on their web site or on the internet.

I also give presentations on prayer from the research I did in writing this book. I have been the guest speaker at several churches, at conferences, Sunday School classes, women’s circle groups, a crusade, reunions, and The Holston United Methodist Home for Children in Greeneville, TN. Please contact me if you are interested in me giving a presentation on prayer to your church or other group.
