How should we do to improve cone crusher efficiency in crushing plant?
3 tips for energy efficient and productive cone crushing
It has been estimated that 5–15% of an aggregate producers’ cost can be associated with the cost of electricity. If cone crusher maintenance is neglected, the result will be a detrimental effect on productivity and an overall higher energy cost per ton of material crushed. It’s not uncommon that aggregate producers’ maintenance teams are not fully aware of the maintenance requirements of a cone crusher or its impact on energy consumption. Make sure that at least these five things are checked.
1- Cone crusher drive belt maintenance
If proper cone crusher drive belt tension and alignment is “not maintained”, the drive belts will slip at the higher power levels and the crusher will inevitably slow down. A slowing crusher will result in excessively high and fluctuating power peaks at a very low crusher throughput tonnage. Improper drive belt maintenance will result in high horsepower consumption at a low crusher throughput tonnage, this inefficient use of connected horsepower will result in a higher energy cost per ton of material crushed (kW/hr per ton).
Drive belt condition, alignment and tension should be checked on a weekly basis (40 hours). A “pulse input speed sensor” can be used to warn operations of a slowing crusher. This speed sensor will also extend drive belt life as the maintenance department will get the opportunity to service (retighten) the drive belts prior to belt failure or prior to crusher stall out.
2- Cone crusher hydraulic power unit maintenance
Improper hydraulic power unit maintenance can cause the pump and motor assembly to cycle more often than it should or worst-case scenario, to run continuously throughout the day. This inefficient use of connected horsepower will result in a higher energy cost per ton of material crushed (kW/hr per ton). It will also result in a shorter life cycle of the hydraulic power unit ancillary components, such as: the pump, motor, coupling, motor starter, pressure switches, solenoid valves, seals, packings, etc. The hydraulic power unit should be inspected on a daily basis (8 hours) for, filter condition, breather condition, leaks, loose connections or unusual noises.
3- Cone crusher discharge compartment maintenance
If the under-crusher discharge compartment is not properly maintained and material builds up on the crusher arms or the countershaft box, crushed product will be restricted from exiting the crushing chamber, this will result in a low crusher throughput tonnage at an extremely high-power level. This inefficient use of connected horsepower will result in a higher energy cost per ton of material crushed (kW/hr per ton). The under-crusher discharge area should be inspected for built-up material on a daily (8 hour) basis.
