CDE has showcased its next generation of waste recycling equipment at CONEXPO-CON/AGG 2023 and launched the latest addition to its range of Infinity high-frequency dewatering screens.
At its stand, CDE presented its recycling solutions, including the next generation of its AggMax scrubbing and attrition system, counter flow classification unit (CFCU) for density separation, ShearClean attrition cells, and EvoWash sand classification and dewatering plant.
The company also unveiled its new P2-168 Infinity screen. With a processing capacity of up to 700 tons per hour, it's the largest model in CDE's range and has been designed specifically for the U.S. market.
Screens are the single biggest point of fatigue in the wash plant setup, but CDE's Infinity range has no welds in the sidewalls, utilizes a galvanized structure, and a VibroSync drive mechanism provides control and even distribution of power. The Infinity range offers increased durability and prolonged operational life.
The new P2-168 model brings all the benefits of the Infinity range to a new scale to support materials producers processing high tonnages. The P2-168 has almost 17 square metres in surface area. The screen decks are reinforced at the centre point which serves to strengthen the screen and provide the operator with the flexibility to produce up to six in-spec products simultaneously.
"The world is changing. Demand for aggregates in our cities is now higher than ever and the supply lines from our quarries are getting further away from where materials are required. Legislation, too, means it's harder than ever to secure approvals for materials. Sustainability – for both profit and planet – is essential but difficult to achieve," says says CDE Director Darren Eastwood.
CDE's AggMax is engineered to operate in tough conditions, maximizing product yield from the abrasive feedstocks due to the spiral alignment of its paddles. Combining feeding, scrubbing, screening, and sizing on one chassis, the AggMax is capable of producing a variety of materials at high processing rates.
CDE's third-generation AggMax 253SR, the latest in the range, has undergone significant improvements to its chassis. Greater modularization enables operators to integrate additional equipment from across the CDE range in line with future commercial needs. Improved access to pumps and other critical components also allows for easier observation and maintenance, minimizing the need for servicing downtime.
CFCU technology allows for the effective separation of two materials of different relative densities. With a variable cut (separation) point, it offers greater control over sand classification providing complete flexibility for the production of various end products and the removal of lightweight contaminants from the fine material fraction.
The latest CFCU 300 model is the biggest in the range and includes CDE's newly developed dart valve, offering improved control of the underflow discharge for a consistent material cut point and optimized throughput.
The EvoWash uses hydrocyclone technology to deliver ideal control of silt cut points and increases product yield. The EvoWash 201 is one of the largest in the CDE range and is capable of processing around 200 tons per hour of feed material.
ShearClean Attrition Cell technology provides contaminant removal through consistent material scrubbing. It maximizes material-on-material impact to both protect downstream processes from wear and ensure the production of in-spec products. The latest DS120 model is developed for high tonnage operations, offering twice the scrubbing volume as its predecessor, the DS60.
