The leading equipment supplier has made an impact with the delivery of a new compact mobile recirculating crusher in New Zealand. Australian Mining writes.
Lincom Group’s size reduction crusher has been successfully processing concrete for Auckland Quarry, a quarry in the city’s central suburb of Mt Wellington.
Auckland Quarry was incorporated in 2015 to meet the needs of the construction industry in the city. With the closure of inner-city quarries in Auckland, contractors were forced to travel greater distances to obtain aggregate supplies and tipping.
The business came about due to the growing demands of customers and to resolve the growing inefficiencies caused by Auckland’s growing urban sprawl.
Given the increasing city traffic and distances to sites, job efficiency had been greatly affected, costing everyone time and money.
Auckland Quarry became a solution by bringing the quarry and its services to the city doorstep, while maintaining quality and service.
The quarry is a busy city yard, handy for tippers to offload concrete at rates per volume / tonne of material. Aggregate products can also be collected to meet specifications.
“Given the growing distance of legal tipping sites and the increasing cost, we aim to operate an efficient solution at the best rate. We offer concrete tipping solutions with a focus on recycling and sustainability,” Auckland Quarry director Jason Boggs says.
Concrete recycling is the smart, cost efficient and environmentally friendly way to reuse aggregate left behind when concrete structures are demolished.
Lincom, a leading provider of material processing equipment, has delivered the Powerscreen Trakpactor 260SR to the Auckland customer.
The equipment supplier combines industry expertise and experience with its product offering to help solve material processing needs within industry sectors.
Lincom achieves this with focus on safety and efficiency of production, maximising the return on investment for customers.
‘’The 260SR crusher has proved ideal as a recycling machine, with metals such as rebar being removed with an overband magnet belt,” Boggs continues.
Lincom sales manager – North Island NZ Caolann Fitzpatrick says the machine is being fed with a crushed all-in 150 millimetre material, producing a GAP 40 product.
“For some time, Jason has been asked to supply a spec’d product, something he couldn’t do before. He now can make a GAP 20, GAP 40 and GAP 65 all by changing the machine’s screen media,” Fitzpatrick says.
GAP 20 is an excellent compacting metal that will create a great firm base. It is a long-lasting metal and is a proven base course for driveways and under paved areas.
GAP 40 also works extremely well when used for a firm base. The most popular applications would be for a top course road material, subdivisions, void filler on roads, subbase material under driveways, and it is a long-lasting metal which compacts to a solid base.
GAP 65, meanwhile, is a commonly used below the base course. It is best used for subdivisions, road work, and as a subbase material as it is a long-lasting metal.
Commenting on the benefits of working with Lincom, Boggs says the company helps with the selection of the right gear for what is needed.
“The sales personnel go above and beyond to provide the technical data and backup to help make an informed decision,” he says.
“The after sales service is an important aspect of why we choose to work with Lincom. From the parts guys to people like Fitzpatrick, who you can ring at the drop of a hat and ask for help in getting what you need when you need it.
‘’It’s great to work with guys we know we can know and trust. They have always been there to help, advise, encourage and make sure that you get what you need.”
Auckland Quarry has tested the crusher in a recycling application and has been satisfied with the machine’s solid performance, versatility and mobility to move from site to site. The Powerscreen 260SR suits the site’s high recycling rate targets.
The 260SR is the ultimate concrete recycling machine. With its twin apron, the CCS can be adjusted independently of one another at the push of a button.
This gives the customer the ability to quickly change the settings to suit different applications and deliver the highest reduction ratios possible, according to Fitzpatrick.
The quarry’s concrete recycling turns unwanted concrete into a new product. Instead of paying fees to dump the old concrete, the operation is providing a sustainable solution for unwanted concrete.
Reinforcing steel embedded in the concrete is also not a problem for Auckland Quarry’s equipment. With the use of a pulverising attachment on an excavator, Trakpactor 260SR breaks it down into small chunks to then be able to put it through the mobile crusher.
Lincom worked closely with Auckland Quarry to understand specific requirements and to provide the best solutions.
The company supplied the Powerscreen Trakpactor 260SR as per customer requirements, including: replaceable tine bar cartridge style grizzly feeder; load management system to control feeder speed; crusher chamber – patented hydraulic overload protection and adjustment system; 4 Bar rotor and twin apron design; economical to operate with HPTO clutch and highly fuel-efficient direct drive system; crusher speed and conveyor height controlled with user-friendly PLC system; modular conveyor with raise/lower facility to aid clearance of rebar; dust suppression system; quick-detach post-screen to convert to standard Trakpactor 260; and recirculating conveyor.
“Another great feature on the machine is the access around the crushing chamber. The platform around the chamber lets you change the blow bars and service the machine with ease,” Fitzpatrick says.
The Powerscreen Trakpactor 260SR horizontal shaft impactor is a compact track mobile crusher designed for the recycling and demolition markets.
The plant is capable of processing a wide range of material at a high output, making it versatile, easy to operate and fuel efficient due to its direct drive system.
Featuring the Powerscreen Trakpactor 260SR fixed hammer horizontal impactor, the plant offers excellent reduction and a high consistency of product shape alongside its key features, including the hydraulic overload protection.
“We like the low noise levels of the Trakpactor 260SR, especially when working in urban environments,” Boggs says.
He believes any industry that requires an end product to be crushed, screened or stockpiled can benefit from the vast range of equipment Lincom offers.
“The mobile crushing plant makes your quarry business much easier and more efficient,” Boggs says.
“The crusher has a post screen and recirculating conveyor, which allows the product to be produced from one machine. We are impressed with the plant’s overall versatility to relocate easily on site. The crusher is easy to transport from site to site, and we will be using this machine at various locations.”
Fitzpatrick adds: “Unfortunately, space isn’t a luxury we have here in Auckland so when choosing the right machine with Jason, it had to be compact and still deliver the required throughput.”
Lincom meets and complies with the relevant standard requirements and machinery guidelines to provide safe work practices for its full equipment range in mines and quarries.
By meeting these standards, Lincom puts steps in place to ensure the safety of workers and the proper functioning of the plant. These codes of practice also assist with the risk assessment of the machine during commissioning.
“Anywhere, anytime, no matter the location, time or situation, we pride ourselves on delivering the right solution and after-sales support,” Lincom states.
