Mica Processing: Methods, Uses and Applications

Posted by H&P Blog on Wed, Oct 14, 2015 @ 10:00 AM

Mica is a mineral of the silicate family, and is known to most people as the glittering gold flakes in some rocks.  It splits into thin sheets when fractured, and is found in all three types of typical rock formations. The most common is muscovite mica, also called potassium mica, which is found in both metamorphic and igneous rocks.  A black-colored variant called biotite commonly appears in igneous rocks such as granite, and also appears in metamorphic rock.  It is comparatively rare in sedimentary rocks, but where it does appear, its thin gold-like flakes are often confused with the genuine material.  Hence the term "fool's gold."

Heyl & Patterson Blog Celebrates Five Years

Posted by H&P Blog on Wed, Jun 17, 2015 @ 09:44 AM

The word "blog" is short for "web log," and is a website with posts providing commentary on a particular subject, much like a newspaper editorial column.  Blogging grew out of the burgeoning digital communities of the 1980s, which included Usenet, CompuServe and Bulletin Board Systems (BBS), and featured running commentary about various topics.  Early versions were a form of web diary that kept an intimate account of the authors' personal lives, and these ultimately evolved into the distinct class of online publishing we know today.  According to the web platform Technorati, there are now over 2.7 million blog posts published each day, and other recent statistics show that there are over 172 million Tumblr blogs and 75.8 million WordPress blogs in existence.

Factors to Consider in Selecting Industrial Drying Equipment

Posted by H&P Blog on Wed, Dec 05, 2012 @ 10:46 AM

Because an industrial dryer is a major capital investment for any organization, it pays to select and test the unit carefully.  Dryer life can be measured in decades, so the selection of inefficient equipment can have a long-term impact on the economic health of the facility that houses it.  The selection of drying equipment is predominantly an exercise in which knowledge, experience and science all play important roles.  Because of the complexity of the drying process, many factors need to be considered and weighed.

Comparing Continuous Conduction Dryers

Posted by H&P Blog on Wed, Sep 19, 2012 @ 11:18 AM

Conduction drying is one way to handle heat-sensitive material, control a drying process atmosphere to ensure final product quality, or use a waste-heat source to cut energy drying costs.  Last week's post discussed classifying drying methods, how a conduction dryer works and looked at the types of batch conduction dryers.  This post compares the types of continuous conduction dryers.

Understanding How a Conduction Dryer Works

Posted by H&P Blog on Wed, Sep 12, 2012 @ 11:24 AM

A dryer uses much more energy than most other bulk material processing equipment.  One dryer that can save energy and enhance a plant's productivity is a conduction dryer.  A look at how conduction compares with other drying methods is the first step in understanding how such a dryer works and whether it's right for your drying needs.  A conduction dryer can handle heat-sensitive materials, control a drying process atmosphere to ensure final product quality, or even use a waste heat source to cut energy costs.
