Metal Powder Briquetting Machine

Metal Powder Briquetting Machine For Sale

The metal powder briquette machine can form various metal powder, such as iron powder, copper powder, aluminum powder, tungsten powder, nickel powder, lead powder and so on, without adding any adhesive. The metal powder pressing machine directly processes raw materials into pressing blocks through cold forming process, without heating, adding additives and so on. In response to customer requests, Zoneding Machinery has developed a new generation of metal powder briquette machine that can press materials into various shapes, such as squares and ovals. 

What is the Metal Powder Briquetting Machine?

A Metal Powder Briquetting Machine, also known as a metal fines briquetter, is a type of high-pressure press. Its main job is to take loose, low-density metal scrap like dust, chips, filings, and turnings and compress them under immense force. This process forms the material into solid, dense blocks or “briquettes.” These briquettes are much easier and cheaper to store, transport, and melt in a furnace. For many ductile metals, the machine achieves this without any binders, a process we call binderless briquetting. The immense pressure causes the metal particles to bond together at a molecular level, a phenomenon known as cold welding.

What are Advantages for Using a Metal Powder Briquetting Machine?

Using a scrap metal briquetting press offers significant financial and operational benefits. You can transform a waste stream into a revenue stream. Here’s how you will benefit:

• Increased Revenue: Briquettes are a high-value product. They can be sold for a much higher price than loose scrap or fines.
• Reduced Material Loss: During melting, fine powders can be lost in the exhaust system. Dense briquettes melt efficiently with minimal loss, meaning you get more finished product from your raw material.
• Lower Transportation and Storage Costs: Briquettes can have a density over 10 times that of loose chips. This means you can store and transport more material in the same amount of space, drastically cutting logistics costs.
• Improved Furnace Efficiency: Uniformly sized briquettes allow for better heat distribution and a more predictable melting process in the furnace, saving energy and time.
• Safer and Cleaner Workspace: Compacting dust and fines significantly reduces airborne particles, creating a healthier and safer environment for your employees.

Which Metal Material Can Be Processed?

Our machines can handle a wide variety of ferrous and non-ferrous metal powders and chips. The key is understanding the properties of your material.Commonly Processed Materials:

• Iron Powder: Including fines from steel mills, cast iron dust, and Direct Reduced Iron (DRI).
• Steel Chips: Mill scale, turnings, and grinding sludge.
• Aluminum Chips and Dust: From machining, casting, and recycling operations.
• Copper Powder and Chips: From wire chopping and manufacturing.
• Brass and Bronze Fines: Common in foundries and machining shops.
• Magnesium Fines: Requires special safety precautions.
• Titanium Sponge and Fines: Also requires advanced safety systems.

How to Test If your Material is Suitable for Making Metal Briquettes?

Before investing in a machine, you must confirm your material will form strong briquettes. A simple first step is the “hand squeeze test.” Take a handful of your metal powder and squeeze it as hard as you can. If it holds some shape, that’s a good sign. However, this is just a rough indicator.

For a definitive answer, you need a professional analysis. At ZONEDING, we encourage potential clients to send us a sample of their material. We will test it in our lab on our roller press machines to determine:

1. The ideal pressure required for strong briquetting.
2. The final density and strength of the briquette.
3. Whether a binder is necessary for your specific material.

This testing process removes the guesswork and ensures you get a machine that is perfectly configured for your needs.

What are Common Features of Metal Powder?

The success of the briquetting process depends heavily on the characteristics of your raw material. Three key features are critical:

• Particle Size: The ideal particle size is typically very small, often less than 5mm. A good mix of different particle sizes helps fill in the gaps, leading to a denser, stronger briquette. Oversized material must be crushed first.
• Moisture Content: High moisture is a problem. During compression, trapped water turns into high-pressure steam, which can cause the briquette to crack or even explode as it exits the press. We generally recommend a moisture content below 4% for optimal results.
• Purity: Contaminants like oil, dirt, or other metals can weaken the briquettes and reduce their value. Clean material produces the best results.

What is the Work Principle of a Metal Powder Briquetting Machine?

The machine’s true job is not just compaction; for many metals, it’s “cold welding.” A feeder, often a screw feeder, forces the metal powder into the gap between two counter-rotating rollers. These rollers have pockets or molds on their surface.

As the rollers turn, they pull the powder into the “nip zone,” where the pressure increases dramatically. The immense pressure, which can exceed hundreds of megapascals, does two things:

1. It forces the air out from between the particles.
2. It causes the clean metal surfaces of the powder to shear against each other, breaking through their natural oxide layers.
   This allows the particles to form true metallic bonds at the atomic level. This “cold welding” is why many ductile metals like iron and aluminum can be formed into strong briquettes without any binders. The compacted material forms into the shape of the roller pockets and is then discharged as a finished briquette.

Applications of Metal Powder Briquetting Machine

The metal powder press machine can also be used to press other materials, such as gypsum, coal powder, ore powder, oxide skin, steel slag, iron powder and aluminum ash, which can also produce a variety of powder materials. Using forced pressurization, precision machining, and prepressing spiral steel billets can also be widely used in metallurgical material, chemical, coal, refractory, and other industries. Metal powder briquetting machine can press oxidize iron, dust, ash, blast furnace slag, manganese ore powder, silicon manganese alloy powder, iron smelting slag, ore concentrate and various ore powder materials in nonferrous metal industry into balls. So it is also called nonferrous metals briquetting machine.

Metal power briquetting machine can be used to suppress coal powder, coke coal, , iron scrap, iron oxide sheet, carbon powder, tailings, sludge, kaolin, activated carbon, coke as well as other powder materials and waste residue.

Characteristics of Metal Powder Briquetting Machine

• Good quality of finished products: The forming pressure is larger than before, so the finished product quality is better.
• Easy to maintain: Molding system is safe and reliable, easy to replace internal parts, and less maintenance work
• Small occupation: The structure is simple and compact, save the site and work reliably.
• Smooth stripping, low noise and less dust.

Metal Powder Briquetting Machine Structure and Composition

Metal powder briquette machine consists of three parts: Feeding part; Transmission part; Molding part.

1.Feeding part:The main purpose is to ensure the uniform feeding of materials into the roller. The screw feeding device is driven by an electromagnetic speed regulating motor and rotated by belt pulley and worm reducer to force the pressed material into the feed port. Due to the characteristics of constant moment of electromagnetic speed regulating motor, when the material quantity of screw feeder is equal to the material quantity required by the host machine, the constant feeding pressure can be maintained to stabilize the pellet quality.

2.Transmission part:The main drive system is motor – triangle belt – reducer – gear – roller. The main engine is powered by electromagnetic speed regulating motor, which is transmitted to the drive shaft through belt pulley, cylindrical gear reducer and coupling. Drive shaft and passive shaft ensure synchronous operation through gear.

3.Molding part:Mainly refers to the main part, the core part is the roll.

In the whole process, metal powder briquette machine can be free to choose according to the customer’s actual situation.

Operation Instruction

1.The operator must carefully understand the contents of this manual in order to understand the performance of the machine and electrical control system, and cannot start work before relevant training.

2.In operation, the operator should first confirm the correctness of the machine work plan before continuous production.

After the machine stops, the operator should turn off the power switch, clean the mold cavity and other parts, so as to avoid curing the raw materials caused by the poor performance of the machine.

What is the Whole Process for Making Metal Briquettes?

A successful operation is more than just the briquetting press. Customers often focus on the machine’s price, but the upstream preparation and downstream handling are just as important. A complete production line is a system.

1. Material Preparation: The raw material might need to be crushed to get the right particle size. It may also need to be dried to reduce moisture content.
2. Mixing (If Necessary): If your material is not ductile enough for binderless briquetting, it will be mixed with a small amount of binder (like sodium silicate) and water in an industrial mixer.
3. Briquetting: The prepared material is fed into the briquetting machine for metal chips. The high-pressure rollers form the powder into dense briquettes.
4. Drying: If a binder was used, the green briquettes need to be dried in a dryer to harden and gain full strength. Binderless briquettes do not require this step.
5. Screening: This is a critical step many overlook. After the press, the material is passed over a screen. Good briquettes go to the product pile, while any un-briquetted fines are recycled back to the machine’s feeder. This closed-loop system maximizes your yield.

How to Choose the Right Metal Powder Briquetting Machine?

Choosing the right machine is vital for long-term success. You need to consider more than just capacity.

• Mechanical vs. Hydraulic Press: A key issue for metals is “springback.” When compressed, metal wants to expand back the instant pressure is released, which can crack the briquette.
  • Mechanical Roller Press: Excellent for high-throughput, 24/7 operations like processing iron ore fines. They are incredibly robust and reliable in harsh environments.
  • Hydraulic Press: Superior for materials with high springback, like steel mill scale. A hydraulic press can be programmed to hold the maximum pressure for a few seconds (called “dwell time”). This gives the metal particles time to deform permanently, resulting in a much stronger briquette.
• Roller Design and Material: The rollers are the heart of the machine. At ZONEDING, we insist on superior engineering.
  • Forged vs. Cast Steel: We use forged steel rollers. Forging creates a much stronger grain structure that resists the immense cyclical stress, preventing cracks. Cast rollers are cheaper but far less durable.
  • Segmented vs. Integral Design: Our rollers use a segmented design. The roller is made of a central shaft with smaller, replaceable wear segments bolted on. When a section wears out, you only replace that small segment in a few hours. An integral (one-piece) roller requires replacing the entire multi-ton assembly, leading to massive costs and downtime.
• Capacity and Power: We will help you calculate the required capacity (tons per hour) and match it with a machine that has the right motor power and roller size for your specific material density.

What is the Price of a Metal Powder Briquetting Machine?

The price of a metal briquette machine can range widely, from around $20,000 for a small-capacity machine to over $500,000 for a large, high-pressure hydraulic system for specialized alloys. The final cost depends on several factors:

• Type of Machine: Hydraulic presses are generally more expensive than mechanical roller presses of a similar size.
• Capacity: Higher tons-per-hour output requires a larger, more powerful, and more expensive machine.
• Material: Briquetting hard, abrasive materials requires rollers made from more expensive, wear-resistant alloys, increasing the cost.
• Ancillary Equipment: The price is for the press itself. Remember to budget for the “hidden factory”: crushers, mixers, dryers, and screening equipment that make up the complete production line.

What are the Shape and Size of the Briquettes the Machine can Make?

The shape and size of the briquettes are determined by the pockets on the machine’s rollers. We can customize these to meet your exact specifications. Common shapes include:

• Pillow Shape: The most common and versatile shape.
• Oval Shape: Similar to the pillow shape, very popular.
• Square or Rectangular: Often used for specific stacking or furnace-charging requirements.
• Custom Shapes: We can machine the roller pockets to nearly any shape you require, including adding a logo or brand name.

The size typically ranges from 20mm to 100mm, depending on the application and the customer’s needs.
