CONSTMACH stationary screening & washing plants deliver efficient processing solutions for natural sand and gravel operations. These installations handle the complete cycle of material screening and washing, producing clean aggregates that meet construction industry standards. The plants operate with production capacities ranging from 100 to 250 tons per hour, accepting feed material up to 200 mm in size at a comfortable 4.5-meter feeding height.
Each plant combines several critical components working in synchronization. The system starts with a feeding hopper equipped with a vibrating feeder, which controls material flow into the processing line. A vibrating screen fitted with washing nozzles performs the dual function of size classification and initial material cleaning. A dedicated feeding conveyor transfers material from the hopper to the vibrating screen, maintaining steady throughput throughout operation. The sand washing stage employs one of three proven technologies: washing screws, wheel washers, or hydrocyclone systems. Stockpile conveyors then transport the finished products to designated storage areas. The entire operation runs through an advanced control cabinet with PLC-based automation using premium SIEMENS or SCHNEIDER electronic components.
The flexibility in washer selection sets these plants apart. Depending on material characteristics and desired cleanliness levels, operators can choose between different washing technologies. Screw washers excel at handling fine materials with high clay content. Wheel washers provide gentle yet thorough cleaning for medium-sized aggregates. Hydrocyclone systems offer high-efficiency fine particle separation with minimal water consumption. Some configurations even incorporate multiple washer types in a single plant, addressing varying material grades simultaneously.
Plant design adapts to specific project requirements. Production capacity directly influences equipment sizing and power requirements. The number and dimensions of final product fractions determine screen deck configuration and conveyor layout. Washer type selection impacts water circuit design and settling system specifications. This customization approach ensures each installation matches its intended application precisely, avoiding both under-capacity bottlenecks and over-specification waste.
The automation system represents a significant operational advantage. Real-time monitoring tracks material flow rates, water consumption, and equipment status. Operators adjust processing parameters from a centralized interface, responding quickly to material variations or production targets. Automated safety interlocks protect equipment from damage during abnormal conditions. The PLC programming allows future modifications as production needs evolve, extending plant service life.
Motor power specifications, generator requirements, and total plant weight all scale with chosen capacity and configuration. This variability means each installation receives precisely matched electrical infrastructure and foundation design. Standard engineering calculations determine exact specifications during the project planning phase, ensuring reliable long-term operation without costly over-engineering.
CONSTMACH stationary screening & washing plants serve quarries, river gravel operations, and recycling facilities worldwide. Their robust construction withstands continuous operation in demanding environments while the modular design facilitates maintenance and component upgrades. The combination of proven mechanical components and modern automation delivers the productivity and product quality that aggregate producers require in competitive markets.
