Nawa Engineers & Consultants P Ltd

Banjara Hills, Hyderabad, Telangana

Features

• Engineered for primary crushing of hard rocks and mineral ores.
• Its kinematics ensure smooth operation and long life.
• Totally weld-free construction ensuring long life against shock loads.
• Robust cast-steel fixed jaw, moving jaw and rear frame - all precision machined for bolting to side plates.
• Special alloy rolled steel side plates precision machined and rigidly secured by shrink-fitted pins and bolts.

• Simple mechanical device for adjustment of CSS with no removal or addition of shim-plates.
• Eccentric main shaft of forged alloy steel with four SKF/FAG heavy duty self-aligning double row roller bearings.
• Cast-steel flywheels fixed on either side of main shaft for precise balancing and enhanced stability.
• High crushing efficiency combined with maximum feed size, a large crushing chamber, higher crushing speed, longer stroke, an effective nip angle and a high reduction ratio.
• High manganese cast-steel jaw plates machined, fully reversible, firmly secured and profiled for smooth flow of material resulting higher throughput.

THE WORLD'S BEST DESIGNED CONE CRUSHERModels: SRM500 & SRM400 Durable NAWACONE Crusher for Secondary, Tertiary and Quaternary Applications

Features

• Exceptional Strength and Durability
• Combination of Roller Bearings and Hydrostatic Thrust Bearings for High Loads
• Highest Mechanical Efficiency to the Tune of 97% and Less Power Consumption
• High Productivity and Superior Product Quality
• Wide Range of Application Flexibility
• Fastest and Easiest Wear Liner Change
• Easy to Operate and Low Maintenance Costs
• Effective Tramp Iron Relief System
• Perfect for Portable and Stationary Plants

The "Duracone SRM" models have several innovative design, construction and operational features that are unique and adds to their unmatched superior performance in secondary, tertiary and quaternary crushing applications.

• It is extemely user friendly. e.g. the top shell can be removed and reinstalled in 20 minutes or less, whenever a liner change, or other maintenance needs that call for top shell to be removed, is required.
• All major maintenance can be done from above the crusher, or from outside the crusher
• The combination of anti-friction roller bearings in the eccentric drive, and the hydrostatic thrust bearing under the head, allow very high loading, and at the same time very low power consumption when running empty, leaving a high percentage of motor power available for crushing. The SRM models are field-tested for crushing river gravel with a compression strength upto 70, 000 psi
• 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
• It is perfectly well balanced, with the c'weights enclosed inside the eccentric mechanism, and thus the c'weights are not subject to wind resistance and abrasion
• The anti-friction bearing design for the drive and eccentric mechanism means crusher speed changes, if required to sent wider range of applications
• Low headroom for portable and stationary plants
