Superior Industries Patriot Cone Crusher

Available in 200-600 horsepower models, the Patriot Cone Crusher features Superior's in-house Vantage Automation, which monitors and controls crusher parameters. The Patriot Cone Crusher is backed by the industry’s first two-year standard warranty, in addition to one-year wear parts protection.

Unlike most crusher models, the Patriot Cone’s counter-shaft spins in a counterclockwise rotation. This causes the crusher to open if clamping pressure is lost, reducing risk of catastrophic failure.

CDE Circular Economy: Maximizing Value from Construction, Demolition Waste

CDE launched its latest video case study demonstrating how construction, demolition and excavation waste can be re-used in high-value construction applications.

Filmed in conjunction with The Sheehan Group, a family-run business, specializing in construction and civil engineering, viewers have the opportunity to watch the full process from the removal of waste materials from a construction site, recycling the waste materials by wet processing and to their reuse in a residential construction project.

The Sheehan Group recognized the need to optimize the reuse of waste materials and the business opportunities in this area. In 2012 they invested in an advanced construction and demolition waste recycling system from CDE. The facility uses the latest wet processing methods to create a range of certified sand and aggregates, which are being used in concrete products for the construction industry. The company are also able to use the filter cake material to engineer landfill cells and cap landfill sites.

Tara Sheehan, financial director, Sheehan Group commented, “We received regular requests for alternative sustainable products, this facility enabled us to fulfill these requests.”

The recycling plant contains a range of equipment that comes together to create an innovative wet processing solution. The plant includes a feed system, AggMax portable logwasher, Infinity screens and Evowash sand washing plant. In addition, the system employs full closed-circuit water recycling with the inclusion of the Aquacycle thickener and Filter Press.

Eunan Kelly, CDE Reco business development manager for Europe said, “CDE Reco are continuously exploring innovative ways to increase diversion from landfill by exploring higher value opportunities for recovered CD&EW materials. We work in close collaboration with each customer to develop a tailored solution to maximixe the volume of material that they can return into the construction market.”

Chris Sheehan, managing director, The Sheehan Group, said, “The CDE installation has allowed us to take better control of our business and integrate our recycled products into construction projects. For example, we now make concrete blocks and ready-mixed concrete using recycled sand and aggregates which were formerly waste materials.”

McLanahan Coarse Material Screw Washers

 

Coarse Material Screw Washers are meant for producers looking to remove light, loamy clays; dirt; crusher dust; and other coatings that cannot be removed by wet screening alone. They are used to process crushed stone and gravel, generally ranging from 3/8- to 4-in. (10 to 100mm).

Coarse Material Screw Washer paddles are used in conjunction with screw flights to provide scrubbing, scouring and agitation. The turbulent washing action combined with the rising current water introduced at the bottom of the box from the feed end results in separation of the lighter fraction from the sound aggregate.

Lighter fractions, such as clay and floating vegetation, float to the surface due to the water rising in the box and then overflow the weir located in the back of the box. The resulting clean product is scrubbed and then conveyed by the paddles and flights to the discharge end of the box.

McLanahan Coarse Material Screw Washers feature abrasion-resistant, white iron paddles that provide maximum wear life and are reversible. This gives producers tremendous flexibility, as reversing some of the paddles will keep material in the box longer, improving retention time. If the operator chooses to move the unit or feed in larger amounts of deleterious material, it is still usable despite changing conditions.

Design elements help keep operation and maintenance simple on Coarse Material Screw Washers. A 360-degree section of flights and wear shoes located in the feed end is able to move material forward, preventing build-up in that area. Screw shafts are made of extra-heavy steel pipe shaft with inner and outer renewable and reversible abrasion-resistant hard iron paddles. Those paddles are preceded and followed by heavy-duty steel flights, equipped with bolt-on inner and outer renewable, abrasion-resistant hard iron paddles. Optional top covers are available, and drive guarding comes standard for personnel safety.

McLanahan offers lab testing for potential Coarse Material Screw Washer users at its Application Research Laboratory.
