Basalt, cast stone

Cast basalt is a highly effective lining material due to its unique characteristics:

• High wear resistance: It has excellent resistance to abrasive wear, significantly increasing the service life of equipment.
• Chemical resistance: Cast basalt is resistant to most acids and alkalis, making it ideal for use in aggressive environments.
• Heat resistance: It can withstand high temperatures without losing its properties.
• Low water absorption: This property prevents corrosion and improves durability.

Main advantages of basalt lining:

• Durability: Significantly extends the service life of equipment.
• Cost-effectiveness: Reduces repair and replacement costs.
• Versatility: Suitable for use in various aggressive environments.
• Ease of installation: Relatively simple installation compared to other materials.

Cast basalt lining is effectively used in various industries, including metallurgy, mining, cement industry, and coal management (coal-fired power plants and coal preparation plants).

Application of cast basalt lining in the mining industry

Main types of wear in the mining industry:

1. Abrasive wear: Caused by the friction of rocks, ores, and other hard materials against equipment surfaces.
2. Erosive wear: Caused by the flow of particles that erode equipment surfaces.
3. Corrosive wear: Chemical attack by aggressive environments (acids, alkalis) leading to equipment material degradation.
4. Impact wear: Caused by the falling of large chunks of ore or rocks onto equipment surfaces.

Technological equipment protected by cast basalt lining:

1. Conveyor systems: Used for transporting rocks and ores. Lining prevents wear and extends the life of conveyors.
2. Pipes, chutes, and hoppers: Used for transporting bulk materials and liquids. Cast basalt protects internal surfaces from abrasive and corrosive effects.
3. Bunkers and silos: Store and dispense materials. Lining reduces wear on walls and bottoms, improves material flow.
4. Mills and crushers: Used for grinding ores. Cast basalt protects internal surfaces from intense wear.
5. Channels and troughs: For transporting slurry and other materials. Lining prevents abrasive and chemical wear.

Key areas in the mining industry where cast basalt lining is effectively used:

1. Crushing plants: Protection of internal surfaces of crushers and mills.
2. Transport systems: Conveyors, pipes, and chutes for transporting ore and other materials.
3. Scrubbers and thickeners: Equipment for cleaning and compacting ore and waste.
4. Dumps and storage: Bunkers and silos for storing bulk materials.
5. Flotation plants: Equipment for mineral separation, where lining protects against chemical attack.

Application of cast basalt lining in the cement industry

Main types of wear in the cement industry:

1. Abrasive wear: Caused by the friction of cement materials and clinker against equipment surfaces.
2. Erosive wear: Caused by the flow of particles that erode equipment surfaces.
3. Corrosive wear: Chemical attack by cement components and additives leading to equipment material degradation.
4. Thermal wear: High temperatures in firing and cooling processes can cause thermal degradation of equipment.

Technological equipment protected by cast basalt lining:

1. Pipelines and ducts: Used for transporting cement materials and dust. Cast basalt protects internal surfaces from abrasive wear.
2. Mills: Used for grinding raw materials and clinker. Lining protects against intense abrasive action.
3. Cyclones and separators: Equipment for particle separation by size and density. Cast basalt extends the life of internal components.
4. Bunkers and silos: For storing and dispensing cement materials. Lining reduces wear on walls and bottoms.
5. Conveyors and troughs: Transport raw materials and finished products. Cast basalt provides protection against abrasive effects.

Key areas in the cement industry for effective use of cast basalt lining:

1. Grinding installations: Mills and crushers where raw materials and clinker are intensively ground.
2. Transport systems: Conveyors, pipes, and troughs used to move cement materials at different stages of production.
3. Dust collection systems: Cyclones, separators, and filters where intense movement of abrasive particles occurs.
4. Storage facilities: Bunkers and silos for storing cement materials exposed to abrasive wear and erosion.
5. Furnaces and heat exchangers: Equipment exposed to thermal and abrasive wear where cast basalt provides additional protection.

Cast basalt lining is an effective solution for protecting equipment in the cement industry due to its high wear resistance and durability. It is especially useful in areas with intense abrasive action and high temperatures.
