A hydraulic metal briquetting machine converts loose metal chips, swarf, turnings and fines into compact briquettes by applying controlled hydraulic pressure. The process reduces the space occupied by machining waste, simplifies material handling and prepares metal scrap for transportation, recycling or remelting.

Dershan Group manufactures hydraulic briquetting equipment for processing aluminum, steel, cast iron, copper, brass and other ferrous and non-ferrous metal chips. Available configurations include small integrated presses, vertical machines, horizontal high-capacity systems, and single- or double-output models.

Why Are Loose Metal Chips Difficult to Recycle?

Turning, milling, drilling and grinding operations generate large quantities of metal chips. Although these chips contain recyclable material, their loose and irregular form creates several practical problems.

Loose chips occupy considerably more space than solid metal. Long turnings may become tangled, while short chips and fines can scatter during collection and transportation. Machining residues may also contain cutting oil, coolant or moisture.

These characteristics can lead to:Inefficient use of storage containers.More frequent material transportation.Difficult or unsafe manual handling.Loss of residual cutting fluids.Contamination between different metal grades.Inconsistent feeding during downstream recycling

Compressing the material into uniform briquettes provides manufacturers and recyclers with a more manageable form of metal scrap.

How Does a Hydraulic Metal Briquetting Machine Work?

The machine uses a hydraulic power system to drive one or more compression cylinders. A typical briquetting cycle includes the following steps:

1. Material feeding: Loose metal chips enter a hopper manually or through a conveyor.

2. Controlled filling: A measured amount of material moves into the compression chamber.

3. Hydraulic compression: The main cylinder applies pressure to compact the chips inside the die.

4. Briquette formation: Loose material becomes a dense cylindrical or customized block.

5. Automatic discharge: The finished briquette is pushed out for collection or transportation.

6. Cycle reset: The machine returns to its starting position and receives the next batch.

Selected Dershan machines use PLC control and continuous automatic discharge. Manual operating modes may also be available for commissioning, maintenance and process adjustment.

What Materials Can Dershan Briquetting Machines Process?

Dershan offers briquetting solutions for a wide range of machining residues:Aluminum chips and powder.Steel and stainless-steel chips.Cast-iron chips.Copper chips, fines and granules.Brass chips and turnings.Magnesium chips.Titanium chips.Lead chips and strips.Grinding residue.Metal cable granules

Material identification is important because each metal behaves differently under pressure. Chip length, bulk density, oil content and particle size can influence feeding stability, briquette density and production capacity.

Dershan evaluates these characteristics when recommending the press structure, motor power, feeding system and briquette dimensions.

Small Metal Briquetting Presses

The DSM Series is designed for factories producing smaller quantities of metal chips. Its integrated structure and compact dimensions make it suitable for installation near CNC machines or designated scrap-collection areas.

Single-Output Briquetting Presses

The DSS Series provides continuous briquette discharge and can process aluminum, brass, copper and iron chips. Dershan lists PLC control, conveyor feeding and horizontal construction among the available specifications for this series.

Parameter or Description

Vertical Briquetting Machines

Dershan’s DSB vertical machines apply pressure from the top down. The vertical structure provides a relatively compact footprint and supports several briquette diameters.

Published DSB models range from the DSB150 to larger machines such as the DSB630 and DSB800. Depending on the model, the listed briquette diameter ranges from approximately 70 to 200 millimeters, with a typical production rate of four to five briquettes per minute.

Horizontal High-Capacity Machines

The DSH Series is intended for centralized or high-volume metal-chip processing. Dershan lists outputs from approximately 2 to 15 tons per hour across the series.

Larger DSH models can produce briquettes with diameters from 200 to 300 millimeters. These systems are suitable for plants that generate substantial quantities of short metal chips and require integration with storage and feeding equipment.

What Benefits Can Metal Briquetting Provide?

Reduced Material Volume

Selected Dershan product pages specify compression ratios of up to 10:1. The actual reduction depends on the initial bulk density, material composition and chip shape.

Reducing the volume of loose chips allows a factory to use storage space and transport containers more effectively.

Easier Storage and Transportation

Uniform briquettes are easier to collect, stack, weigh and load than loose or tangled turnings. They are also less likely to scatter during handling.

Cutting-Fluid Recovery

Metal chips produced by machining may retain oil or coolant. Hydraulic compression can separate part of this fluid when the machine is equipped with an appropriate collection system.

For chips with a high fluid content, Dershan can combine centrifugal drying with briquetting. The recovered fluid may be collected for suitable treatment or reuse, depending on the customer’s process.

More Consistent Recycling Material

Separately processed briquettes provide recyclers and foundries with a more uniform feedstock. Keeping aluminum, steel, cast iron, copper and brass in separate material streams also helps prevent contamination.

Automated Material Handling

Briquetting equipment can be integrated with lifting devices, storage hoppers, shredders and conveyors. A centralized system reduces repeated handling between machining areas and the recycling station.

When Is Preprocessing Required?

Not every type of metal chip should enter the press directly.

Short, relatively uniform chips can usually move through a controlled feeding system. Long and tangled turnings may bridge inside the hopper or prevent consistent filling. In these applications, a metal-shavings shredder can reduce the material to a more suitable size.

Wet chips may benefit from centrifugal drying before compression. A complete processing sequence can include:

Collection → lifting → shredding → centrifugal drying → storage → controlled feeding → briquetting

Dershan supplies standalone presses as well as lifting, flipping, shredding, centralized feeding and spin-drying briquetting solutions.

How Should Buyers Select a Briquetting Machine?

The largest machine is not automatically the correct choice. Buyers should provide the equipment manufacturer with accurate operating information, including:Metal type and grade.Chip dimensions and shape.Hourly and daily chip volume.Bulk density.Oil, coolant or moisture content.Required briquette size.Available installation space.Electrical voltage and frequency.Preferred feeding method.Required automation level.Downstream recycling or furnace requirements

Material photographs, videos and samples can help Dershan recommend an appropriate model. When several CNC machines feed one recycling area, a centralized production line may be more suitable than multiple independent presses.

Frequently Asked Questions

What is a hydraulic metal briquetting machine used for?

It compresses loose metal chips, swarf, powder or turnings into compact briquettes for easier storage, transportation, recycling and remelting.

Can the machine process both ferrous and non-ferrous metals?

Yes. Dershan offers machines for steel, cast iron, aluminum, copper, brass and several other metals. Different materials should normally be processed separately.

Does briquetting require a binder?

Metal chips are typically compacted by hydraulic pressure without adding a chemical binder. Suitability depends on the material and required briquette condition.

Can oily metal chips be processed?

Yes, but the required configuration depends on fluid content. A collection system or centrifugal drying stage may be recommended.

What is the output of a Dershan metal briquetting machine?

Dershan’s published product range extends from compact DSM machines rated for tens of kilograms per hour to DSH horizontal systems rated up to 15 tons per hour. Actual output is material- and model-dependent.

Does every application need a shredder?

No. Short, flowable chips may be briquetted directly. Long, tangled or bulky turnings often require size reduction before feeding.
