With concrete pieces measuring up to 500 mm, a considerable amount of fines and pockets of damp material throughout the stockpile, the feed was far from consistent. These variations can affect how material moves through a crusher, making it harder to maintain production and achieve the required finished product.
The objective was to turn this mixed demolition waste into a 25 mm minus product suitable for use on a hardstand area. The challenge was achieving that result efficiently, despite the irregular condition of the incoming material.
The Powerscreen Trakpactor 320SR is a tracked horizontal shaft impact crusher that combines crushing, screening and recirculation within a single mobile plant.
For this application, its integrated recirculating system played an important role. Rather than allowing material outside the required size to move into the finished stockpile, the system returns it to the crusher for further reduction.
To achieve the customer’s required 25 mm minus product, the machine was configured with a 35 mm top screen deck and a 25 mm bottom deck. Both the intermediate and oversized fractions were recirculated through the transfer conveyor, keeping the operation focused on producing a single usable material.
The crusher was operating with a two-high blow bar arrangement, with the primary apron set at 90 mm and the secondary apron at 30 mm. These aprons help control the crushing process by influencing how material is broken down as it passes through the machine.
This configuration allowed the customer to process the material through one integrated crushing and screening operation, reducing the need for additional equipment to handle material requiring further reduction.
Despite the challenging feed conditions, the machine achieved an average throughput of 170 tonnes per hour, with an average fuel consumption of 28 litres per hour.
Fuel consumption was recorded over an eight-hour shift using Powerscreen Pulse telematics, providing a useful picture of how the machine performed under actual working conditions.
With an established presence in Western Australia, our team provides local support to help customers maintain their equipment, address operational challenges and minimise unnecessary downtime.
From routine servicing and wear-part replacement to troubleshooting and technical advice, we understand that every hour of lost production can affect project schedules and operating costs.
In applications such as concrete recycling, where abrasive materials place ongoing demands on crusher components, timely maintenance is particularly important.
