CATHAY SWS-200 Sand Screening Machine | Processing capacity 200t/h including fine sand recovery

Product Overview

CATHAY sand screening machine is an innovative equipment integrating screening, washing, dehydration and fine sand recovery, specially designed for processing machine-made sand, river sand and sea sand. Through modular integrated design, a single device can complete the workflow of three traditional devices, reducing site occupancy by 60% and investment costs by 45%.

Core advantages

1. Four-in-one system

- Grading and screening: multi-layer vibrating screen (2-4 layers), grading accuracy 0.075-20mm

- Powerful water washing: double spiral grinding wheel, processing capacity **50-300t/h

- High-efficiency dehydration: high-frequency dehydration screen, finished sand moisture content <8%

- Fine sand recovery: cyclone + dehydration screen combination, recovery rate ≥95%

2. Energy-saving and environmentally friendly design

- Water circulation system: water consumption is reduced by 70% (only 1-1.5m³ water/ton sand)

- Zero pollution discharge: equipped with sludge filter press (optional)

- Noise reduction structure: overall noise ≤75dB

3. Intelligent control system

- PLC centralized control: one-button start and stop of all modules

- Fault self-check: real-time monitoring of bearing temperature, water pressure and other parameters

- Production statistics: automatic recording of shift production/daily production data

4. Durable structure

- Wear-resistant material: The screen plate is made of NM400 wear-resistant steel, with a service life of ≥18 months

- Anti-blocking design: Screen self-cleaning device

- Module quick change: Key component replacement time <2 hours
