Integrated Wet Processing Excellence
Custom-built for Lindsey Aggregates, the Red School House electric-powered plant includes the R2500 wet screening module; a primary scalping screening unit capable of processing over 500 tons per hour. The plant includes a number of patented features including the unique weld-free galvanized Infinity Screen™ for increased durability. The R2500 scalping station separates oversized material, which is fed to the primary crusher, whilst 0-1” is conveyed to the M4500 modular sand washing plant, in order to wash out the natural sand.
Upon its launch, more than ten years ago, the M-Series was hailed as the first modular feeding and screening system. The M4500 was the first machine in the industry to combine feeding, screening, sand-washing and stockpiling onto one compact chassis. This approach enabled Lindsey Aggregates to dramatically increase the capacity of its operations by constructing a 500tph wet plant in conjunction with its existing mobile crushing fleet and without being restricted by the limitations of a fixed traditional plant setup. The M4500 produces more than 250tph of in-spec sands as well as variable natural and crushed aggregates to DOT specification.
In addition to the M4500, the plant features the M2500 modular sand & aggregate washing systems, both of which work in parallel to handle natural and crushed aggregate flows within the washing and crushing circuit.
Integrated to the M4500 is the EvoWash™ sand washing plant. Featuring hydrocyclone technology, the EvoWash™ guarantees removal of the minus 200 mesh fraction while retaining all quality fines in the final sand product. It also maximizes dewatering to 12-15%, resulting in the ‘ready-to-sell’ nature of the product straight off the belt.
Combined, the technology is ensuring operations at Lindsey Aggregates are fully optimized, bringing new business opportunities and attracting new customers to the company through its expansion into new, thriving markets.
Vandish said, “We knew the team we wanted to work with. Having had the opportunity to view CDE’s technology in action at a site in Texas our decision was further confirmed and confidence assured. The process of working together has exceeded both our expectations and their promise, extending right through to after-sales care.”
“The CDE team continue to be in regular contact. In particular, the CustomCare after-sales team have been a great resource since the journey began. It’s comforting for us to know the team is readily available should we need assistance.”
The CustomCare service provides dedicated regional engineer support for every customer. Coupled with CDE’s readily available stock of common parts – worth $3m – and complete order history, the service ensures shorter downtime, low shipping costs and boosts in productivity.
Brian Barndt, CDE CustomCare Regional Service Engineer, keeps in touch with the Lindsey Aggregates team regularly. He explains, “I’ve gotten to know the team really well. After the harsh winter, we helped to re-commission the Lindsey Aggregates site. So, whether they have a question about parts, tech advice, checking stock levels or inspections, I’m at the end of the phone and happy to help.”
As a result of the collaborative approach from design through to after-sales service, a smarter, integrated solution has been installed that meets all objectives. The C-33 sand has also received required approval NYDOT.
In total, Lindsey Aggregates is now producing four new products. In addition to its three original crushed products, it’s now producing the high friction C-33 spec, mason sand, and a number of chip products for use in black top and concrete. The C-33 spec sand is used in paving and concrete and is considered the mainstay of all construction works. While exploring and fulfilling many different applications for mason sand, the company is primarily using it for the cost-effective filling of sandbags due to the current urgent issue of lake-front flooding in upstate New York.
Warren Vandish said, “It’s very exciting to officially launch our expansion into this new line of business. Wet processing was new to us and CDE was with us every step of the way. The CDE USA team of expert engineers invested significant time and energy into understanding our operations, materials, challenges, and ambitions. Their focus on innovation has helped us, in turn, to innovate as a business, ensuring a sustainable operation for the future, and we remain partners in this process.
“The new plant is truly a game-changer. The quality sand and aggregates from our now expanded product portfolio are ready for market straight from our belts – the efficiency is remarkable.”
Heron added, “Together with our customers, CDE is unlocking a New World of Resource and driving alternatives for sand production. Lindsey Aggregates is now producing manufactured sands to supplement finite natural sand resources. We recognize the increasing importance of expanding and developing sustainable business models and are proud to have created that in cooperation with the team at Lindsey.”
