The wire-wound copper wire scrap briquetting machine is a specialized device for processing loose copper scraps such as waste enameled wire and copper wire, compressing them into high-density, easily transportable briquettes. This is an important step in the recycling and processing of scrap metal.

Below is a detailed introduction to this device:

I. Main Objectives and Advantages

Reduced Volume: Loose copper wire scraps are very fluffy and take up a lot of space. Briquetting reduces their volume to 1/3 to 1/5 of their original size, significantly reducing storage and transportation costs.

Increased Density: Briquetting into high-density blocks (typically with a specific gravity of 5-6 tons/cubic meter) meets the density requirements of smelters for furnace feed, facilitating subsequent smelting.

Easy Handling: Briquetting is easier to handle and load into furnaces using forklifts, grabs, and other equipment than loose scraps, resulting in a higher degree of automation.

Reduced Oxidation and Loss: Compaction reduces the surface area exposed to air, minimizing oxidation losses during storage and transportation, and preventing wind loss and spillage.

Enhanced Economic Value: Briquettingd copper is more desirable to smelters and typically fetches a higher price than loose material.

II. Main Equipment Types

Based on drive method and structure, they are mainly divided into two categories:

Hydraulic Briquetting Machines

High Pressure: Extremely high briquette density.

Smooth Operation: Relatively low noise.

High Adjustability: Pressure and holding time are easily controlled through the hydraulic system.

Various Capacities: From small (hundreds of kilograms per hour) to large (tons per hour) production lines.

Principle: Utilizes a hydraulic system (cylinders) to provide enormous pressure (tens to hundreds of tons) to compress copper shavings into briquettes within a mold.

Features:

Applications: The most mainstream and widely used type, suitable for medium and large-sized recycling and processing centers.

Mechanical (Crankshaft Connecting Rod/Screw) Briquetting Machines

High Speed: Usually faster than hydraulic presses.

Relatively low energy consumption.

Pressure is relatively fixed, and adjustment is less flexible than hydraulic presses.

Principle: Converts rotary motion into linear extrusion motion through a motor-driven crankshaft connecting rod mechanism or screw.

Features:

High speed: Generally faster than a hydraulic press.

Relatively low energy consumption.

Pressure is relatively fixed, and adjustment is less flexible than a hydraulic press.

Applications: Suitable for applications where extremely high density is not required, but efficiency is a priority.

III. Key Components of the Equipment

A typical (hydraulic) copper wire briquetting machine usually includes:

Hopper:Stores the copper wire shavings to be processed.

Pre-compression mechanism:Some machines pre-compress the loose material to improve the efficiency of the main pressure cylinder.

Main pressure cylinder:The core component, providing the main pressure required for final forming.

Mold (mold box): Determines the final shape (cubic prism, cylinder, octagon, etc.) and size of the briquetting block.

Block ejection mechanism:Pushes the pressed block out of the mold.

Hydraulic system:Includes a hydraulic pump station, valves, pipelines, and oil tank, providing power to the equipment.

Electrical control system:PLC control enables automatic/manual operation and monitors parameters such as pressure and temperature.

Binding device (optional): During the briquetting process, some machines automatically wrap metal wire around the block or add a bag to prevent the block from scattering during transportation.

IV. Factors to Consider When Selecting a Briquetting Machine

Raw Material Characteristics:

Types: Pure copper wire, enameled wire, copper shavings mixed with small amounts of other metals.

Size and Shape: Length of the shavings, whether they are tangled.

Impurities: Contains plastic sheeting, oil, iron filings, etc.

Capacity Requirements: How many tons of material need to be processed per hour or per day? This determines the size of the equipment model.

Block Density Requirements: Different downstream customers (smelters) may have different density standards.

Block Shape and Size: Commonly rectangular blocks (e.g., 80mm x 60mm x thickness) for easy stacking.

Automation Level: Is fully automatic feeding, discharging, and packaging required?

Plant Conditions: Floor space, height, and power capacity (three-phase) requirements for the equipment.

Budget: Ranges from tens of thousands to millions of RMB. Imported brands (such as Andritz from Germany and Japan) are expensive, while domestic brands offer better value for money.

V. Process Flow Summary

Feeding → (Pre-compression) → Main Compression/Forming → Pressure Holding → Block Ejection → (Automatic Binding/Bagging) → Collection and Stacking

VI. Market and Brands

International Brands: Mature technology, stable performance, high price. Examples include ANDRITZ and BRYANT.

Domestic Brands: Rapid technological advancements in recent years, significant cost-performance advantages, occupying a large market share. Many machinery manufacturers, such as Nantong Forging Press, Jiangsu Weili, and those in Hebei province, produce these products.

Recommendation: Before purchasing, it is best to provide raw material samples to the equipment manufacturer for trial pressing to determine the most suitable model, mold, and process parameters. Simultaneously, visit the manufacturer's case study sites to understand the actual operation of the equipment.
