The "copper and brass shavings pressing machine" is a highly specialized and important piece of equipment in the metal recycling and processing industry. It is mainly used to press loose copper shavings, brass shavings (and other non-ferrous metal shavings, such as aluminum shavings) into high-density blocks (cake-shaped or cylindrical) under high pressure for easy transportation, storage, and smelting.

Below, I will give you a comprehensive introduction to this device:

I. Main Functions and Advantages of the Equipment

Reduced Volume and Cost Savings: Reduces the volume of loose briquette materials to 1/3 to 1/5 of their original size, significantly lowering transportation and storage costs.

Easy Melting:High-density briquettes with uniform composition melt quickly in the furnace, resulting in less burn-off (reduced oxidation) and improved smelting efficiency and metal recovery rate.

Improved Working Environment:Prevents briquette flying, maintains a clean workshop, and reduces metal dust pollution and safety hazards.

Increased Economic Efficiency:Briquetting products can be sold directly to smelters as high-quality raw materials at a higher price than loose briquette materials.

High Automation: Modern briquetting machines can automatically feed, press, and output briquettes, saving labor.

II. Main Types

Based on working principle and structure, they are mainly divided into two categories:

Vertical (Four-Column) Hydraulic Briquetting Machine

Features: The most common type, with high pressure (from tens to thousands of tons), producing high-density briquettes. Utilizes four-column guidance for smooth operation.

Applications: Suitable for processing various copper and brass shavings, especially long and coiled shavings, and for large-scale continuous production.

Output Shape: Mostly square or cylindrical shavings.

Horizontal (Side-Pressure) Hydraulic Baling Machine/Packing Machine

Features: Applys pressure from the side, usually with a pre-compression chamber, pre-compressing loose materials before high-pressure shaping.

Applications: Particularly suitable for processing very thin shavings, machined "copper granules," and applications requiring extremely high density.

Output Shape: Mostly rectangular shavings for easy stacking.

III. Key Factors to Consider When Choosing a Briquetting Machine

If you are purchasing equipment, please pay attention to the following points:

Raw Material Characteristics:

Types: Pure copper shavings (red copper), brass shavings (copper-zinc alloy), bronze shavings, etc. Different alloys have different hardness and ductility.

Form: Are they long curls from turning, short shavings, or fine powder from milling/drilling? Long curls may require pre-crushing or the use of a model with pre-compression capabilities.

Moisture and Oil Content: Oil and moisture affect briquette density and quality. Some models can be equipped with heating devices to evaporate oil and water ("hot pressing"), improving adhesion.

Equipment Parameters:

Nominal Pressure (tons): Determines the final density of the briquettes. Copper shavings typically require higher pressure.

Briquette Size and Weight per Batch: Determined based on your production volume and subsequent processing requirements (such as the feed size of the smelting furnace).

Production Capacity (tons/hour): Matches your daily processing volume.

Automation Level: Requires automatic feeding (screw conveyor or belt conveyor), automatic weighing, PLC control, etc.

Core Component Quality:

Hydraulic System: The reliability of branded oil pumps, valve assemblies, and seals is crucial, directly affecting pressure stability and equipment lifespan.

Mold Material: High-strength wear-resistant alloy steel must be used to withstand repeated high pressure and metal friction.

Frame Structure: The machine body must have sufficient rigidity and strength to ensure no deformation during long-term operation.

IV. Usage Process (Typical)

Collection and Pre-treatment: Collect copper shavings generated in the workshop, and perform impurity removal (removing iron filings and other metals) and crushing (for long, curled shavings) if necessary.

Feeding: Feed the shavings into the hopper of the briquetting machine via a hoist or conveyor.

Compression: PLC control automatically completes feeding, compression, pressure holding, and demolding.

Block Extrusion and Collection: The compressed blocks are automatically ejected and fall onto the conveyor belt or collection basket.

Packaging and storage: The cooled briquettes can be packaged and stored or directly loaded onto trucks for shipment.

V. Market and Brands

Domestic Brands: High cost-performance ratio, convenient after-sales service, and mature technology. There are many professional metal briquetting machine manufacturers in China, mainly concentrated in Jiangsu, Zhejiang, Shandong, and Guangdong provinces.

Imported/Joint Venture Brands: Brands from countries such as Germany, Italy, and Japan offer advanced technology and stable performance, but are expensive.

Our Recommendations

Clarify Your Needs: First, assess your factory's raw material type, monthly/daily processing capacity, and desired briquetting density and shape.

On-site Trial Run: If possible, bring your own raw materials to the equipment manufacturer for a trial run. This is the most direct way to verify the equipment's effectiveness.

Case Studies: Check if the equipment supplier has successful cases processing similar raw materials and conduct on-site visits whenever possible.

Focus on After-Sales Service: Ensure the manufacturer provides timely installation, commissioning, training, and subsequent maintenance services.

Summary: Copper and brass briquetting machines are an excellent investment for improving resource utilization, increasing economic benefits, and achieving cleaner production. Choosing a machine suitable for your material characteristics and production scale is crucial.
