Brass scrap and copper powder pressing machine?

The "Brass Shavings and Copper Powder Briquetting Machine" is a key piece of equipment in the field of metal recycling and resource reuse. It is mainly used to press scattered brass shavings, chips, powder and other waste materials into high-density cylindrical or other shaped blocks (breads) under high pressure in a cold state.

I. Core Purpose and Advantages of the Equipment

Reduce Volume, Lower Transportation and Storage Costs: Loose copper scrap has a very low bulk density; after briquetting, the volume can be reduced to 1/3 or even less of the original.

Facilitate Storage, Transportation, and Management: Regular, solid briquettes are easier to stack, load, unload, and count.

Improve Smelting Efficiency and Reduce Losses:

High briquette density allows for faster sinking into the molten pool after entering the furnace, reducing oxidation.

Prevents Fine Powder from Being Carried Away by Flue Gas (Burn-off), Improving Metal Recovery Rate.**

Reduce Energy Consumption and Auxiliary Material Consumption During the Smelting Process.**

Increase Sales Value: Briquetted products are standard recycled raw materials, easier to sell than loose scrap, and command higher prices.

II. Main Types of Equipment

Based on output and automation level, the main types are:

Vertical Hydraulic Briquetting Machine:

Structure: The main cylinder applies pressure vertically downwards, with the mold located below.

Features: Compact structure, small footprint, easy maintenance. Suitable for small to medium-sized recycling stations or workshops. Typically semi-automatic (manual feeding and briquetting), with tonnage ranging from tens to hundreds of tons.

Horizontal Hydraulic Briquetting Machine

Structure: The main cylinder applies pressure horizontally, with the mold on the side.

Features: Good stability, easy to automate feeding and briquetting. Suitable for large-scale continuous production, typically with a large tonnage (over 200 tons).

Four-Column Hydraulic Briquetting Machine

Structure: Employs four-column guidance, high precision, and good rigidity.

Features: Smooth operation, strong resistance to eccentric loads, the most common type of industrial-grade briquetting machine on the market

III. Key Components of the Equipment

Hydraulic System: The core power source, including motor, oil pump, hydraulic valves, and cylinders. Stable pressure and good pressure holding performance are required.

Machine Frame: Bears high pressure and requires sufficient strength and rigidity; typically welded from high-quality steel plates.

Die: Determines the shape (e.g., cylindrical, square) and size of the blocks. The die material must be wear-resistant, usually high-hardness alloy steel.

Electrical Control System: Controls the entire briquetting process (feeding, pressurizing, pressure holding, die removal, and block ejection). Modern equipment often uses PLC control and touchscreen operation.

Feeding System (Optional): For automated production lines, a screw feeder or conveyor belt will be provided.

IV. Purchasing Considerations

Raw Material Characteristics: Clarify whether the raw material you are processing is pure brass shavings or mixed copper shavings. What are the particle size, oil content, and moisture content? This directly affects the equipment tonnage and die design.

Output Requirements: Select a suitable model (tonnage and level of automation) based on the average daily processing capacity (tons/day).

Block Requirements: What are the required block dimensions, individual block weight, and density? This determines the pressure and mold specifications.

Equipment Quality:

Main Cylinder and Oil Pump: Brand and quality are crucial, affecting pressure stability and lifespan.

Steel Thickness: The machine body must be solidly constructed to ensure no deformation during long-term use.

Control System Stability.

After-Sales Service: Is the timely supply of installation and commissioning, operation training, and vulnerable parts (such as seals and molds) adequate?

V. Market Overview and Recommendations

Domestic Manufacturers: China is the main producer of this type of equipment, concentrated in Henan, Shandong, Jiangsu, and Guangdong provinces. Prices range from tens of thousands to millions of RMB, depending on configuration and automation level.

International Brands: Brands such as ALJON and BRIQUETTING SYSTEMS (USA) are known for their large-scale, fully automated, and high-performance equipment, but are expensive.

Our Recommendations:

Clarify Needs: First, clearly define your material situation, production targets, and budget.

Compare Multiple Suppliers: Contact 3-5 reputable manufacturers, providing material samples and requirements, and request solutions and quotations.

On-site Inspection: If possible, visit the manufacturer or existing customer's site to observe equipment operation.

Pay Attention to Dies: Dies are consumable parts; understand their lifespan, replacement costs, and ease of use.

Trial Run and Verification: Require a trial run using your raw materials to verify briquette density, yield, and equipment operating status.
