Nawa Engineers & Consultants offers cone crusher used for secondary, tertiary and quaternary crushing applications. Its features include mechanical efficiency to the tune of 97 per cent and low power consumption. It is user-friendly as the top shell can be removed and reinstalled in 20 minute or less, whenever a liner change, or for other maintenance needs that call for top shell to be removed, if required. Major maintenance can be done from above or outside the crusher. The combination of anti-friction roller bearings in the eccentric drive, and the hydrostatic thrust bearing under the head, allows very high loading, at the same time consumes low power when running empty, leaving a high percentage of motor power available for crushing. The low friction in the drive also prevents the shaft spinning when the crusher is running empty, or is lightly fed with the segregated feed, and thus eliminates the need for a shaft brake. The anti-friction roller bearings in the drive and eccentric mechanism ensure constant geometric alignment, which reduces wear and tear on the gear drive and thrust bearings compared to those fitted with bronze bushes.
