The Anaconda SR520 Quarry Screener is a track-mounted screener — sometimes referred to as a mobile screen plant — designed to separate and grade bulk materials such as crushed stone, gravel, sand, and recycled aggregates. Anaconda is a well-established manufacturer of mobile processing equipment, building a range of screeners, trommels, and conveyors primarily for quarrying, mining, construction, and waste-recycling applications. This 2024 machine is offered used and is located in California, USA.
At the heart of the unit is a high-energy, two-bearing screen box measuring 5 feet by 20 feet, configured with two full decks. The top deck carries four 5-foot side-tension panels, while the bottom deck uses three end-tension panels of approximately 6 feet each. The screen angle is hydraulically adjustable between 18 and 30 degrees, and the entire screen box can be raised hydraulically to simplify mesh changes. Walkways are fitted around the screen box to give safe access for maintenance and media replacement. Screen media and its installation are not included with the machine.
Material enters through a generously sized hopper measuring 6 feet wide by 14 feet 1 inch long, with a maximum volume of 10.4 cubic yards (8 m³). A tipping grid measuring 7 feet wide by 16 feet 2 inches long sits above the hopper and can be operated either via radio remote control or a manual valve, giving operators flexibility in how material is introduced to the machine. From the hopper, a 42-inch-wide feeder belt with plain conveyor belting and variable speed control meters material onto the screen box.
Three discharge conveyors handle the separated fractions. The main conveyor belt is 42 inches wide and variable speed. The midsize conveyor is 32 inches wide with Chevron (C15) belting, variable speed control, and a discharge height of 17 feet 9 inches (5.4 m). The oversize conveyor is also 32 inches wide with Chevron (C15) belting and variable speed control. All conveyor speeds are independently adjustable, allowing operators to tune material flow to suit differing throughput requirements.
Propulsion is provided by 500 mm (19.685-inch) rubber tracks with a travel speed of 0.62 mph (1 km/h), enabling the machine to be repositioned around a site under its own power. The powerpack is a Caterpillar 4.4 Stage 5 diesel engine rated at 96.5 kW, meeting current emissions standards. Onboard fuel capacity is 122 gallons (465 L) and the hydraulic tank holds 145 gallons (550 L), supporting extended production runs between refuelling and servicing intervals. The sale excludes freight, screen media and its installation, taxes, fees, and permits.
