A variety of washing and classifying equipment innovation was on display this summer at Hillhead 2022 in the United Kingdom. Terex Washing Systems (TWS), CDE and McLanahan Corp. were among the companies serving the U.S. to showcase some of their latest offerings at the trade show. Here’s a rundown of what the companies promoted.

TWS launched a new machine at Hillhead while debuting an enhanced AggreSand 206.

The new machine, TWS’s FM Pentium, is capable of washing one grade of sand and one aggregate on a single chassis, the company says. The FM Pentium is a static sand and aggregate-washing unit, combining a collection tank, centrifugal slurry pump, hydrocyclones and a dewatering screen.

With a feed rate of up to 150 tph of pre-screened material, TWS says the FM Pentium can produce up to 120 tph of washed sand.

The improved AggreSand 206, meanwhile, emerged a decade after the initial research and development of the AggreSand family. The first AggreSand – the 165 – launched in 2013, with the 206 model following.

According to TWS, new AggreSand 206 features include an increased feed hopper size option to allow for greater feed capacity, a redesigned cyclone underflow box and a dewatering screen to provide sharper cuts in blending and enhanced end product. The company says the new chassis design enables the AggreSand to be more easily integrated with other TWS products.

In addition, TWS says access points were improved to simplify maintenance. A high-grip walkway allows for access to critical components.


CDE also showcased wet-processing solutions at Hillhead, including the R-Series primary scalping unit (R4500), the AggMax logwasher and its counter flow classification unit (CFCU).

CDE says its R4500 was developed to handle troublesome materials, including heavily clay-bound minerals and waste materials, offering high-energy screening of material and oversize removal before it enters the AggMax logwasher for scrubbing and classification.

According to CDE, its AggMax technology is engineered to operate in the toughest of conditions to maximize product yield from the most abrasive and clay contaminated of feedstocks. Combining feeding, scrubbing, screening and sizing on one chassis, the AggMax is suitable for a variety of material streams – aggregates, sand, overburden, scalpings and more.

The CFCU, meanwhile, is a system that handles the removal of lightweight contaminants from fine material fraction. Its features provide sand classification by mass and density where water is used to suspend particles at the cut point. The CFCU also provides the benefit of being able to tailor the final sand gradation specific to its end use, CDE says.


Also at Hillhead, McLanahan displayed the UltraWash 6206 for the first time in Europe.

The UltraWash 6206 can be configured to produce up to three clean aggregates and two washed sand products, according
to McLanahan.

Additionally, McLanahan’s latest tailings management solution – a decanter centrifuge – was on the stand. The company says the machine provides an alternative to filter and belt presses while improving tailings handling, helping to eliminate settling ponds, improving water recovery and meeting environmental regulations.
