Sand Recycling Machine

The sand recycling machine is a complete solution for sand washing plants to maximize resource utilization. The innovative design combines a hydrocyclone with a dewatering screen (model FX300 as example) to recover fine sand particles (0.16-3mm) from wastewater. Featuring automatic operation and compact structure, it significantly reduces water consumption while improving sand quality. This environmentally-friendly equipment is particularly valuable for concrete plants and sand production lines seeking to minimize material loss and water usage.

The Sand Recycling Machine is the core equipment for resource recovery in modern sand plants and mining operations. Designed to process washing wastewater containing 0.16-3mm fine sand, it achieves up to 95% material recovery while reducing water consumption by 50-70%. The innovative hydrocyclone-dewatering screen system ensures efficient solid-liquid separation, producing saleable sand with <20% moisture content. Its fully enclosed structure and automatic operation make it essential for environmentally sensitive projects requiring zero discharge standards.

When selecting models, key factors include solid concentration (FX300 for <15% slurry, FX550 for high-density waste) and system configuration (including thickeners and water recycling units). Future developments will focus on IoT-based slurry density control and wear-resistant composite materials to further improve recovery rates in abrasive material applications.

Products Display
