Iron Powder Briquetting Machine

What is an Iron Powder Briquetting Machine?

An Iron Powder Briquetting Machine is a high-pressure press designed specifically for metal powders. It is not like a standard biomass briquetter. It is built to handle extremely abrasive materials under immense force. This machine uses two counter-rotating rollers to compact iron fines into a solid block, or briquette. The goal is to create a product that is strong enough to be handled and transported without breaking. This process is often called cold pressing. It turns a low-value, problematic waste into a high-value, standardized furnace charge.

The iron powder briquetting machine is also called powdered iron briquetting machine or oxide scale briquetting machine. The raw material can be directly put into production after crushing without adding water. Iron ore powder (iron powder, iron ore) is one of the most important metal powder materials in metallurgical industry, which is used in large amount in the powder metallurgy production and its consumption accounts for about 40% of the total consumption of metal powder. The iron powder briquetting machine can guarantee the intensity and density of iron powder briquettes.

The iron briquette machine is a kind of high-pressure ball press which is used to press the hard-granular material. And The iron powder briquette machine is characterized by large forming pressure, adjustable revolution of main engine and screw feeding device. It is widely used, and many materials can be pressed into a ball.

What are Advantages of Iron Powder Briquettes?

You are not making briquettes; you are making a reliable furnace charge. This is the most important advantage. Furnace operators need a consistent, predictable material. Loose powder is inefficient. Briquettes solve this problem. They provide significant operational and financial benefits.

• Improved Smelting Efficiency: Briquettes have a uniform shape and size. This allows hot gas to flow evenly through the furnace, leading to better heat transfer and faster, more complete reduction.
• Reduced Material Loss: Turning dust into solid blocks stops it from being blown away by furnace gases. You get more metal from the same amount of raw material.
• Lower Transportation and Storage Costs: Briquettes are much denser than loose powder. You can store and transport more material in the same space, which saves you money.
• Safer and Cleaner Workplace: Briquetting dramatically reduces dust. This creates a safer, healthier environment for your workers and reduces the risk of dust explosions.

What are Features of Iron Powder?

Iron powder is an industrial abrasive. This is the most critical feature to understand. Materials like mill scale and iron ore fines are hard and sharp. When you mix them with a little water for briquetting, you create a perfect grinding paste. This paste is then forced between two rollers under massive pressure. This puts extreme stress on every part of the machine. A standard machine will be ground to pieces in a short time. Your Iron Briquetting Machine must be built specifically to resist this constant wear and tear.

What are the Critical Features of a Durable Roller Iron Powder Briquetting Machine Press?

A machine’s long-term performance is determined by its frame and rollers. These two components handle the incredible forces needed for metal powder briquetting. At ZONEDING, we focus on building machines that last in the harshest environments.

• Roller Material is Everything: The rollers are the heart of the machine and the most expensive wear part.
  • Standard Steel: Will fail in weeks.
  • Manganese Steel (65Mn): The bare minimum, but wears quickly.
  • High-Chromium Alloy (9Cr2Mo): This is the professional standard. We use forged, heat-treated high-chromium alloys. They are extremely hard and abrasion-resistant. They cost more at the start but can last 5 to 10 times longer, making your cost-per-ton much lower.
• A Rigid Frame is Non-Negotiable: The frame holds the rollers together against thousands of tons of separating force. If the frame flexes, your briquettes will be inconsistent. Over time, flexing will cause metal fatigue and frame failure. We use massive, single-piece cast steel housings that are stress-relieved to ensure maximum rigidity and a very long service life.

What is the Structure of the Iron Powder Briquetting Machine?

A modern iron briquetter is a combination of heavy mechanics and precise hydraulics. Each part has a specific job in creating a high-quality briquette.

1. Forced Feeder: This screw conveyor sits above the rollers. It actively pushes the fluffy or sticky iron powder down into the press. This ensures a consistent feed, which is essential for uniform briquettes.
2. Rollers: A pair of rollers made from special alloy steel. They have pockets machined into their surface to form the briquette shape. One roller is fixed, and the other is movable.
3. Hydraulic System: This is the hidden giant. A powerful hydraulic system pushes the movable roller against the fixed one, creating immense pressure. It also acts as a safety system, allowing the roller to move back if a piece of tramp metal enters the press, preventing catastrophic damage.
4. Main Frame: The heavy-duty cast steel structure that holds everything together and resists the pressing forces.

Zoneding Iron Briquette Machine Classification Based on Structure

Hydraulic protection device iron powder ball press has hydraulic protection device.

As a key part, the mould is made of composite components with 65Mn, which is wearable and can be replaced in case of being worn. 

This type of briquette machine is equipped with shock absorbers, which can better protect the equipment from the impact of hard materials.

Iron powder briquetting machine is designed with ball bowl adjustable device to ensure that the ball bowl of two rollers is always in the adjustable range.

Applications of Iron Powder Briquetting Machine

The iron powder briquetting machine is a kind of widely used metal powder processing equipment in coal industry, metallurgy industry and chemical industry materials. The briquettes made by this equipment can be used as metal smelting materials and chemical reactant. Some good cases in point are as follows. Steel plant reprocess iron ore powder briquettes to make steel; chemical plant uses mill scale briquettes to make ferrosilicon.

It can be used to suppress coal powder, iron powder, coking coal, aluminum powder, iron filings, iron oxide sheet, carbon powder, slag, gypsum, tailings, sludge, kaolin, activated carbon, coke and other powder material and waste residue in power plants, metallurgy, refractory material industry, chemical industry, energy, transportation, heating, etc.

Requirements of Processed Materials

>>Size Requirements:
It is suitable for particles of no larger than 8mm, and the smaller, the better. Because it is good for make high-density balls. Besides, the materials are preferably powdery and granular.

>>Moisture Requirements:
Humidity below 12% is better for the material to be briquetted. It’s not easy to press the powder into ball.

If the material is of large size, the crusher machine is needed.
If the material is of high humidity, a dryer machine is needed.
and If the material is too dry, adhesive or water is needed; or you can select a dry powder briquette machine.

Performance Advantages of Iron Powder Briquetting Machine

The powdered iron briquetting machine is suitable for pressing wet powders, which means that it is necessary to add the proper amount of water or other liquid adhesives into the materials. This product has an excellent pressing effect on various materials such as caustic-burned magnesia powder, sinter, sludge in steel plant and an iron fine meal. Iron powder briquette machine is equipped with reducer, and the motor and the reducer drive the machine through arc tooth coupling and the two rollers of the main engine rotate in the opposite direction driven by the synchromesh gear.

How Does a Iron Powder Briquetting Machine Work to Turn Iron Powder into Valuable Briquettes?

The process is simple in concept but requires a very powerful machine. It works by applying extreme pressure to a prepared mixture of iron powder.

1. Feeding: The prepared mix of iron powder and binder is loaded into the machine’s hopper.
2. Forced Compacting: The forced feeder screw pushes a consistent amount of this material down into the gap between the two rollers.
3. Pressing: As the rollers turn towards each other, they draw the material into the pockets. The hydraulic system applies massive pressure, compacting the powder into a solid shape.
4. Discharging: Once past the point of maximum pressure, the formed briquettes fall out from between the rollers onto a discharge conveyor.
5. Curing: The freshly pressed briquettes are still “green” or weak. They are then sent to a dryer to cure and gain their final strength.

What Types of Iron Fines Can Be Processed?

Almost any type of iron-bearing dust or sludge can be briquetted. The key is to prepare the material correctly. Common materials processed by a mill scale briquetter and iron fines press include:

• Mill Scale: A flaky surface that forms on hot rolled steel. It is very rich in iron.
• Blast Furnace Dust: Fine particles captured from the furnace exhaust gases.
• Steel Sludge: Oily waste from rolling mills and other processes. This needs pre-treatment to reduce oil content.
• Direct Reduced Iron (DRI) Fines: High-purity iron powder.
• Iron Ore Fines: Fine particles from the mining and screening process.

What is the Complete Process: From Powder to High-Strength Briquette?

A successful operation is a complete process, not just a single machine. The briquetting machine is the centerpiece, but the preparation steps are what guarantee a good result.

1. Material Preparation: Some materials may need to be crushed or screened to achieve the right particle size.
2. Mixing: The iron powder is fed into a double-shaft mixer. Here, water and a carefully selected binder are added and blended thoroughly to create a uniform, workable paste.
3. Briquetting: The mixture is then fed into the iron powder briquetting machine to be pressed into shape.
4. Drying and Curing: The green briquettes are transported by a conveyor to a dryer (like a mesh belt dryer). They are heated for a specific time to remove moisture and allow the binder to cure. This step develops the crucial cold crushing strength needed for handling.

How to Choose the Right Iron Powder Briquetting Machine?

Start with your final product, not the machine’s capacity. The first question is not “how many tons per hour?” The right question is, “What strength does my briquette need to survive the journey to the furnace?” You must define the required Cold Crushing Strength with your furnace operator. This single specification will determine the pressure needed from the machine. From there, you can select the right model, roller material, and motor size. A supplier who asks about your tonnage before asking about your strength requirements is selling you a machine, not a solution.

What Factors Influence the Final Price of an Iron Briquetting Machine?

The price is directly related to the machine’s ability to survive. A cheap machine will not last. The key cost drivers are the parts designed to handle extreme pressure and abrasion.

• Capacity (Tons per Hour): A larger machine with bigger rollers and a more powerful motor will cost more.
• Roller Material: High-chromium alloy rollers (9Cr2Mo) are more expensive than standard steel, but they are essential for a low total cost of ownership.
• Frame Construction: A heavy, solid cast steel frame costs more to produce than a welded plate frame, but it provides the necessary rigidity and lifespan.
• Hydraulic System Quality: A reliable, high-pressure hydraulic power pack with quality components is a significant part of the cost.

What is the Typical Maintenance Schedule of an Iron Powder Briquetting Machine?

Maintenance is about managing the constant wear from abrasive material. A proactive maintenance schedule is essential to keep the plant running and avoid expensive, unplanned downtime.

• Daily: Check for hydraulic leaks. Listen for unusual noises from bearings. Check the temperature of the main bearings.
• Weekly: Check the tension and alignment of drive belts. Lubricate all grease points. Inspect the roller surfaces for signs of wear.
• Monthly: Check the hydraulic oil level and filter condition. Inspect the teeth and gears in the reducer. Tighten all major bolts on the frame and roller assembly.
• Annually: A full inspection of the hydraulic system, main bearings, and roller condition. Plan for roller replacement based on wear rates.
