Stone crushers supply the aggregate behind every highway, housing project and concrete plant, and across Rajasthan and Gujarat there are crusher plants running long hours in dust, heat and constant shock. A crusher's bearings, gearboxes and belts take more punishment than almost any other machine. Small lubrication habits make the difference between a crusher that runs all season and one that stops every week.
Grease jaw crusher and vibrating screen bearings with a good EP2 grease, little and often, and keep dust out. Run cone crushers on clean, cool circulating oil of the grade the maker specifies. Use EP gear oil in conveyor drives, and keep the multi-belt V-belt drives tensioned, aligned and replaced as matched sets. Dust control is the most important job of all.
| Machine | What it needs | Watch point |
|---|---|---|
| Jaw crusher | EP2 grease (lithium, lithium complex or as specified) for eccentric shaft and pitman bearings; multi-belt C or D drives | Shock, dust, belt slip at start |
| Cone crusher | Circulating lubrication oil of the grade the maker specifies (often VG 100–150, depending on season); hydraulic oil for settings | Oil temperature, filter condition, dust in the tank |
| VSI crusher | Oil or grease for rotor bearings, as specified; V-belt drives | High speed, bearing temperature |
| Vibrating screens | EP2 grease or oil as specified for exciter bearings | Vibration, heat, dust |
| Conveyors | EP2 grease for pulley bearings; EP gear oil (VG 220–320) for drive units | Dust, missed greasing points |
| Feeders and hoppers | Grease and gear oil as specified | Shock loads |
Crusher and screen bearings are large and heavily loaded, and dust is everywhere.
A grease with molybdenum disulphide (MoS₂) can help in slow, heavily loaded, shock-loaded positions where the crusher maker allows it.
Cone crushers depend on a circulating oil system: tank, pump, filter, cooler and return. Three rules keep it healthy:
Conveyor drives and feeders run long hours under dusty conditions. Use the EP gear oil grade the maker specifies, often VG 220 or 320, keep breathers clean, and check the oil level weekly. Our guide to choosing industrial gear oil explains when a higher grade helps in summer.
Jaw crushers and VSI crushers are usually driven by several C, D or wedge-section belts on a large flywheel pulley. Typical problems:
The fixes: replace complete matched sets, check tension weekly on hard-working drives, gauge the grooves at every change, keep guards fitted and clear the crusher before restarting. Read why V-belts fail early and the V-belt tension guide.
Walk the plant at the start of each shift: listen for squealing belts, look for dust caked on bearings and leaks under gearboxes, check oil levels and the cone crusher oil temperature, and grease the points due that day. Most crusher breakdowns give a warning first.
At 45 °C ambient, bearings, gearboxes and oil systems run much hotter. Keep coolers and gearbox fins clean, shorten greasing intervals on hot bearings, and keep belts properly tensioned, because slip creates heat too.
Banesto makes industrial greases, gear oils and Beltone V-belts, and supplies customers across Gujarat and Rajasthan. Tell us your crusher models and belt codes and we will suggest a simple, crusher-ready list.
Which grease is used in jaw crusher bearings?Usually an EP2 grease such as lithium or lithium complex, or the grease the crusher maker specifies. Apply little and often, and keep dust out.
Which oil is used in cone crushers?A circulating lubrication oil of the grade the cone crusher maker specifies, which may change between summer and winter. Keep it clean and cool.
Why do crusher V-belts burn or break?Slip at start-up under load, dust in the grooves, mixed old and new belts and misalignment. Replace complete sets and keep tension right.
How often should crusher bearings be greased?Follow the maker's schedule; in dusty, hot conditions, small daily or per-shift shots are common for critical bearings.
