Glen Mills Inc. is publishing a new series of brochures entitled "Tech Tips." Written by Glen Mills' engineering staff for owners, operators and buyers of size reduction, sample preparation and mixing equipment, "Tech Tips" offers a variety of information for processing and sampling needs. The first issue describes the four general classes of size reduction: impact, abrasion, cutting and compression. The brochure also provides a mesh/micron/inch cross-reference chart. Glen Mills offers sample evaluations at its test facility and rents, leases and sells equipment. To order free copies of "Tech Tips," visit www.glenmills.com.
