What is a Mineral Powder Briquetting Machine?

A mineral powder briquetting machine is a type of roller press designed for high-pressure compaction. Its only job is to take dry or semi-dry mineral powders and squeeze them between two counter-rotating rollers. These rollers have pockets, or molds, on their surfaces. The extreme pressure forces the powder particles to bind together, forming solid, dense briquettes. This process is essential for making fine materials easy to handle, transport, and use in industrial processes like smelting.

Advantages of Pressing Mineral Powder into Briquettes?

Turning your fines into briquettes offers huge financial and operational benefits. It is not just about waste management; it is about value creation.

• Creates a Sellable Product: The biggest advantage is turning a waste product into a valuable commodity. Steel mills and smelters will pay for briquettes but not for loose powder.
• Reduces Transport Costs and Losses: Briquettes are dense and easy to handle. You can load them onto trucks or trains without losing material to the wind. This significantly cuts down on logistical waste.
• Improves Industrial Processes: Briquettes have uniform size and chemical properties. When used in a furnace, they allow for better airflow and more predictable, efficient melting compared to fine powders which can choke the furnace.
• Reduces Environmental Impact: Compacting dust and fines into solid blocks eliminates air pollution at your site and during transport. This can help you meet environmental regulations.

Which Mineral Powders are Suitable for Briquetting?

Our powder briquetting plant solutions can handle a wide range of materials. Some of the most common applications we see include:

• Iron Ore Fines: One of the biggest applications. Briquetting allows these fines to be used in blast furnaces or DRI plants.
• Manganese Ore Fines: Used for creating ferroalloys.
• Chrome Ore Fines: Essential for stainless steel production.
• Fluorite (Fluorspar) Powder: Used as a flux in steelmaking.
• Mill Scale: A waste product from steel rolling mills that is rich in iron.
• Magnesium Oxide: Used in refractories and other industries.
• Coal and Coke Fines: Turning coal dust into fuel briquettes.

Differences Between Mineral Powder and Ordinary Briquetting?

Briquetting mineral powders is much more demanding than briquetting softer materials like charcoal or sawdust. This is a critical point that many buyers miss. The machine has to be engineered for a tougher battle.

The main difference is abrasion. Many people look at Mohs hardness and think they understand the material. But the real enemy is attrition. You are forcing millions of tiny, sharp, hard mineral grains through the rollers under extreme pressure. It acts like a high-pressure grinding paste. Standard steel rollers, even hardened ones, will be destroyed in months. For mineral fines briquetting, you must use rollers made from high-chromium forged steel. These materials are not just hard; they are built to resist the intense grinding wear. This costs more initially but saves you a fortune in downtime and replacements.

Custom-made equipment is also available. Mineral powder, metal powder, coal powder, gypsum, carbon powder, kaolin, activated carbon, coke powder, iron, ore, iron oxide, slag, refractory materials and other materials can also be pressed. Application scope is broad, and mineral powder briquetting machine is suitable for the use of refractory material, power plants, metallurgy, energy, transportation, heating and other industries, which also can effectively improve the efficiency of the use of materials, improve the utilization of waste, and bring good economic benefits to the public. There is a certain environmental effect, and the improvement of the people’s living environment has a certain effect.

Additionally, the briquettes made by this nonferrous metal powder forming equipment can be used in the blast furnace process and metal smelting as chemical and smelting auxiliary material. Since that, this mineral powder briquette machine has found wide application in the coal industry, metallurgy industry, chemical industry, etc. To be specific, the steel plants can supply mill scale briquettes made using this briquette equipment to chemical plants for manufacturing ferrosilicon. Aluminum briquettes can be put into smelting furnace for extracting aluminum. Fluorite briquettes can be used as cosolvent for making steel.

Structure of Ore Powder Briquetting Machine

• Feeding part: It ensures that uniform materials can be fed into the double roll by quantitative feeding.
• Transmission part: The main transmission system is motor – triangle belt – reducer – open gear – roll.
• Forming part: It mainly refers to the main part, the core part is roller.

What is the Key Components of a Mineral Powder Briquetting Machine?

A professional briquette press machine is more than just two rollers in a frame. Every part is critical for performance and longevity.

• The Rollers: This is the heart of the machine. As we said, they must be made of highly abrasion-resistant materials like forged high-chrome steel.
• The Frame: The frame must be incredibly rigid. A weak frame will bend slightly under pressure. This causes the briquettes to have dense edges and a soft, crumbly center. A superior machine uses an over-engineered frame with pre-stressed tie rods to ensure zero bending.
• The Feeder: For fine powders, a simple gravity hopper will not work. You must have a forced screw feeder. This screw actively pushes the powder down into the rollers. It removes trapped air and pre-compacts the material. This ensures every briquette has a consistent weight and density.
• Bearings and Lubrication: The immense pressure goes through the bearings. Cheap machines use standard bearings that fail quickly. A professional machine uses oversized, top-quality bearings with an automated centralized lubrication system. This system delivers the right amount of clean grease at the right time, which is the secret to a long machine life.

How Does the Mineral Powder Briquetting Machine Work?

The process is straightforward but requires precision.

• Material Preparation: The mineral powder is first mixed. If needed, a binder and water are added in a separate mixer to achieve the right consistency.
• Forced Feeding: The prepared material is loaded into the hopper. The variable-speed screw feeder starts pushing the powder down, de-aerating and pre-compacting it.
• High-Pressure Compaction: The pre-compacted powder enters the gap (the “nip”) between the two rotating rollers. The immense hydraulic or mechanical pressure squeezes the material into the roller pockets, forming the briquettes.
• Discharge: The formed briquettes fall out from under the rollers onto a discharge conveyor belt. They are then usually sent to a dryer to cure and gain their final strength.

What is the Price of a Mineral Powder Briquetting Machine?

The price of a mineral powder briquetting machine can range from $30,000 for a small, simple unit to over $500,000 for a large-scale, high-pressure hydraulic system. The price depends on several key factors:

• Capacity (Tons per Hour): A larger machine costs more.
• Pressure Requirement: Materials like iron ore that need binderless briquetting require extreme pressure, which means a more expensive, robust machine.
• Roller Material: High-chromium forged steel rollers are more expensive but essential for abrasive minerals.
• Motor and Reducer Brand: Using top-tier brands like Siemens or SEW adds to the cost but ensures reliability.
• Hydraulic vs. Mechanical System: Hydraulic systems offer better pressure control and protection but are more expensive than mechanical presses.
