How we made
our choices
When we ask readers how we can best help them
keep track of changes in the products and services
they use to produce aggregates, almost everyone
wants an annual short list of the really important
stuff.
No wonder. The sheer volume of introductions is
overwhelming. Aggregates Manager covers dozens of
products each year in its RollOuts departments and
Supply Lines features.
So each year, our staff reviews all the product
introductions we’ve covered for the past year (our
Top RollOuts “year” actually runs from the December
2009 issue through the November 2010 issue) to
pick out 25 that we believe are worth further review.
Our priorities are new concept products — which
are rare — new series/new generation products in
categories that relate to the aggregates industry, and
other rollouts which serve our readers’ interests by
increasing competition in a product category.
Inevitably, we omit deserving products, either
because we just didn’t understand the significance
of the product or because the announcing company
didn’t communicate what was special about the prod-
uct, or both. In either case, we apologize in advance
for these omissions.
UNIFIED SCREENING & CRUSHING
Increased production throughput
Unified Screening & Crushing’s new SuperFlow screens are a hybrid of wire cloth and ure-
thane support strips. Each wire is said to vibrate independently to provide a harmonic fre-
quency that reduces plugging and blinding, improving throughput performance by as much
as 30 percent. The company says the screens perform
well when screening dry material, but are especially
productive when handling wet or sticky material. The
screens are available in three styles.
