CONSTMACH's SW-1240 mobile screening and washing plant represents a highly practical solution for operations requiring efficient sand and gravel processing at 60 tons per hour capacity. The unit combines all essential washing and screening equipment on a single wheeled chassis, eliminating the complexity of multiple separate machines and significantly reducing installation time on site.
The SW-1240 model features a 1,200 x 4,000 mm vibrating screen paired with a 400 x 4,000 mm screw washer, providing thorough material cleaning while maintaining consistent throughput. Material enters through a feeding hopper positioned at 4,600 mm height, which connects to the vibrating screen via a dedicated conveyor. This arrangement ensures smooth material flow and prevents bottlenecks during operation. The screening system incorporates an integrated washing mechanism that removes clay, silt and other contaminants from aggregates, delivering cleaner end products that meet specification requirements.
One standout characteristic of this plant is its genuine mobility. The hydraulic leg system allows operators to level the unit quickly on uneven terrain, and the compact transport dimensions of 15 x 2.8 x 4.2 meters comply with international road transport regulations. This means the SW-1240 can move between job sites without special permits or complicated logistics. The wheeled chassis design proves particularly valuable for contractors working on multiple projects simultaneously or those serving remote locations where permanent installations aren't feasible.
Operating the SW-1240 requires just 37 kW of total motor power, with a recommended 75 kVA generator for standalone operation. The plant comes equipped with fold-up stockpile conveyors that reduce transport height and deploy rapidly when needed. CONSTMACH has fitted the unit with a Siemens-Schneider based automation system controlled entirely through a tablet interface. Operators can monitor and adjust plant parameters remotely, reducing the need for constant physical supervision and improving overall site safety.
The design offers notable flexibility beyond standard screening and washing duties. Operators can remove the screw washer module when projects require only screening, effectively converting the plant for different applications without purchasing additional equipment. For sites with reliable grid power, the optional diesel generator can be omitted to reduce operating costs. This adaptability extends the plant's usefulness across various project types and material specifications.
Weighing 20,000 kg, the SW-1240 maintains stability during operation while remaining transportable with standard heavy-duty trailers. The combination of processing capacity, compact footprint and quick setup makes this model particularly suitable for medium-scale sand and gravel operations, whether processing natural deposits or recycling construction materials. CONSTMACH's mobile screening and washing technology delivers dependable performance where traditional stationary plants would prove impractical or uneconomical, giving operators the production capacity they need with the mobility modern projects demand.
