NAWACONE - Louis Johnson's "Duracone SRM"

THE WORLD'S BEST DESIGNED CONE CRUSHER
Models: 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

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

The minimum recommended CSS is determined by the crushing chamber selection and operating conditions. Capacities are approximate total throughout based on an average material having a bulk density of 1600 kg/ton or 100 lbs/ft³. Throughput capacity will vary depending on the type of material, feed gradation, moisture content, chamber selection, feed method and other site specific operating conditions.
