Copper Rice Shaking Table

Updated: 2026-07-15

Overview

The Copper Rice Shaking Table is a specialized separation device used primarily in the recycling industry for processing waste wires and cables. It's designed to efficiently separate copper granules (often called 'copper rice') from plastic insulation materials through a combination of vibration and gravity separation techniques. The equipment represents a crucial step in the wire recycling process, offering an environmentally friendly solution for recovering valuable copper materials while reducing landfill waste. Its development has significantly improved the efficiency of metal recovery operations compared to traditional manual separation methods.

Structure and Working Principle

The shaking table consists of a vibrating deck, frame, vibration motors, rubber damping components, and an adjustable incline mechanism. The deck surface typically features riffles or grooves that facilitate material separation as the table vibrates. Operation relies on differential settling velocities of materials. When crushed wire particles are fed onto the vibrating deck, the combination of vibration and flowing water (in wet models) causes denser copper particles to settle differently from lighter plastic fragments. The copper collects at one end while plastics move toward the opposite side, achieving separation.

Key Features

Modern copper rice shaking tables offer several important features that enhance their performance. These include adjustable vibration frequency and amplitude, allowing operators to optimize separation for different material types. Many models incorporate water circulation systems for wet separation processes, improving separation efficiency. Advanced models may include automatic feeding systems, integrated control panels, and modular designs for easy maintenance. The equipment typically boasts high recovery rates (often 95%+) for copper particles down to 0.1mm in size, making it highly effective for fine material separation.

Application Areas

The primary application of copper rice shaking tables is in the recycling industry, specifically for processing waste electrical wires and cables. They're commonly used in dedicated recycling plants, scrap metal processing facilities, and by specialized wire recycling companies. Beyond copper recovery, similar shaking table technology finds applications in other material separation processes, including electronic waste recycling and precious metal recovery. The equipment is particularly valuable in regions with strict environmental regulations, as it enables efficient material recovery while minimizing waste.

Maintenance and Precautions

Regular maintenance is crucial for optimal shaking table performance. Key tasks include periodic lubrication of bearings, inspection of vibration motors, and checking rubber damping components for wear. The deck surface should be kept clean to ensure consistent separation performance. Safety precautions include proper equipment grounding, installation of protective covers on moving parts, and operator training in emergency stop procedures. Environmental considerations may require water treatment systems for wet separation models to meet local wastewater regulations.

B2B Procurement Guide

When procuring copper rice shaking tables for industrial use, several factors should be considered. Processing capacity (typically measured in kg/hour) should match your production requirements. Separation efficiency specifications should be verified, with reputable manufacturers providing performance guarantees. Other important considerations include energy consumption, space requirements, and availability of spare parts. It's advisable to request demonstrations or visit existing installations when evaluating equipment. For reference, mid-capacity models (500-1000kg/h) typically range from $10,000 to $15,000, while high-capacity industrial systems can exceed $20,000.
