India “Mining Sector” Stats

The GDP contribution of the mining industry varies from 2.2% to 2.5% only but going by the GDP of the total industrial sector it contributes around 10% to 11%. Even mining done on small scale contributes 6% to the entire cost of mineral production. Indian mining industry provides job opportunities to around 700,000 individuals.

Equipment In Industry

Construction and mining equipment cover a variety of machinery such as hydraulic excavators, wheel loaders, backhoe loaders, bull dozers, dump trucks, tippers, graders, pavers, asphalt drum / wet mix plants, breakers, vibratory compactors, cranes, forklifts, dozers, off-highway dumpers (20T to 170T), drills, scrapers, motor graders, rope shovels etc. They perform a variety of functions like preparation of ground, excavation, haulage of material, dumping/laying in specified manner, material handling, road construction etc. These equipments are required for both construction and mining activity.

Lubrication In Mining & Equipments

Statistically every single tone of metal produced creates the demand of 1 million lire of lubricant oil. The market for lubricant product in country is estimated at 2.2 billion litres annually.
mechanical loads cumulatively result in a high wear rate of bearings and friction points. Lubrication is therefore absolutely necessary in order to provide the right protection.

• Moisture and particles – combined with heavy loads, shock loads, extreme pressures and continuous operation – create a difficult job for any lubricant.
• Mining gearboxes tend to be overloaded, which leads to overheating and excessive wear. This often results in premature failure of the gears. Other common mechanical issues include emulsification of the gear oil due to water contamination and extreme foaming.

Most wire ropes are lubricated during the wire rope manufacturing process, but the lubricant will not last the life of the rope. When looking for a wire rope lubricant, we should choose a lubricant that contains no acids or alkalis, possesses the adhesive strength to stay on the rope, penetrates between wires and strands, has high fluid film strength, resists oxidation, and remains pliable. It is important to remember that most wire ropes fail from the inside out. Proper lubrication will help prevent deterioration of wire rope due to rust and corrosion.
