Each mining plant has its own unique set of challenges due to moisture, abrasion, and the chemical environment. Mining equipment and structures are affected by highly aggressive environments, which may include:
- Abrasion is one of the major environmental conditions in mining that impacts the performance of equipment and structures. Equipment needs to move hard and abrasive material, from location to location, in processes, such as extraction, transportation, crushing and milling of metallic and non-metallic minerals.
- Exposure to corrosion due to the presence of water in wet, corrosive processes, such as flotation of the mineral and thickening of the concentrate.
- Exposure to harsh chemicals in the base-metal refining process that is conducted in acid environments, and the electrowinning process that is carried out in a very aggressive and corrosive sulfuric acid environment.
TYPICAL PROBLEMS
Severe wear occurs in different parts of the grinding equipment such as the liner and external shell.
POTENTIAL SOLUTIONS
Belzona 1000 Series erosion resistant systems for safeguarding metallic substrates.
TYPICAL PROBLEMS
Mining process materials can rapidly erode surfaces of bulk handling systems such as shafts and chutes.
POTENTIAL SOLUTIONS
Welding can be avoided by using Belzona abrasion resistant lining systems consisting of alumina tiles and epoxy polymers to withstand wear.
TYPICAL PROBLEMS
The material that passes through the hopper is very abrasive and corrosive, which can lead to worn out walls and holes. In addition, the continuous flow of such materials and vibrations can cause the hopper’s exterior to eventually crack. Also, the rubber gasket of the flanges deteriorates, allowing material to fall through.
POTENTIAL SOLUTIONS
Belzona Ceramic Carbide materials can rebuild and protect surfaces against corrosion and abrasion. While Belzona Metallic Polymers can be used in-situ and without the need for welding to repair damaged metallic substrates.
TYPICAL PROBLEMS
Constant abrasion due to conveying rough materials result in wear and corrosion of the auger, shaft, and troughs.
POTENTIAL SOLUTIONS
The wear can be minimized with the application of Belzona abrasion resistant products. Also, the troughs can be rebuilt with a variety of 1000 Series products to extend the service life of machinery.
TYPICAL PROBLEMS
Conveyer belts regularly suffer damage due to general wear and tear and heavy abrasion.
POTENTIAL SOLUTIONS
Belzona Elastomeric Polymers are ideal for repairing and rebuilding holes and tears in conveyer belts. The product offers high elasticity and mechanical strength to resist abrasion.
TYPICAL PROBLEMS
Seizures and heavy loading commonly result in abrasive wear to bearing housings.
POTENTIAL SOLUTIONS
Belzona paste-grade metallic polymers are recommended to rebuild oversized housings and return them to service with minimum downtime.
TYPICAL PROBLEMS
Abrasive material wear away at pipes, typically occurring at bends and T-junctions where material impinges on the wall.
POTENTIAL SOLUTIONS
Belzona ceramic polymers provide excellent abrasion and wear resistance against fine and coarse particles and high temperatures.
TYPICAL PROBLEMS
Pumps are used to transport corrosive and abrasive materials and are susceptible to damage from harsh operational environments.
POTENTIAL SOLUTIONS
Belzona Elastomers and ceramic composites offer outstanding resistance against severe erosion to pump lining an impellers.
TYPICAL PROBLEMS
Compressive stress enlarges splits and holes in tires due to the stretching of the rubber.
POTENTIAL SOLUTIONS
Belzona Elastomers quickly repair and prevent further deterioration of rubber substrates, extending the life cycle of tires.
TYPICAL PROBLEMS
The presence of acids, alkalis, and salts create a very aggressive and corrosive environment for assets.
POTENTIAL SOLUTIONS
The chemical-resistant polymers in the Belzona 4000 Series offer seamless coatings that protect tank walls and floors from chemical attack, assuring a long working life.
Belzona epoxy materials repair and protect equipment used in the mining industry from abrasion.
