PSG Series Cone Crusher

Overview
The PSG series cone crusher is a state-of-the-art high-performance crushing machine developed by YUANNAI according to inter-particle breakage principle. Adopting crushing concept instead of grinding, this machine is a perfect combination of high swing frequency, optimized chamber and rational stroke.

By far, this hydrocone crusher has been widely applied to metallurgy, building material, road building, chemical and silicate industries, suitable for breaking mid-had or above mid-hard ores and rocks.

Working Principle
When the cone crusher works, motor drives V-belt, big belt wheel, transmission shaft, bevel pinion and bevel gear pinion to make eccentric bushing rotate. Crushing cone axis is forced by the eccentric bushing to spin, which makes mantle sometimes close to the bowl liner, and some times far away from the bowl liner. Therefore, materials in the annular crushing chamber formed by fixed and mobile cones are continuously impacted, squeezed, curved and crushed. After repeat procedures, materials are crushed into required size and discharged from the outlet of quartz cone crusher.

Features
1. Excellent stability
Spring release mechanism will automatically release uncrushable materials and then is automatically reset to the fixed return point, during which crushable materials are normally discharged form the outlet of rock crusher.

2. High performance
Compared with spring cone crusher with same mobile cone, this equipment comes with higher performance and productivity.

3. Uniform particle size
Due to inter-particle breakage principle, final products come in cubic shape instead of flake shape, and particle size is more uniform.

4. Convenient chamber cleaning
When the machine stops under load conditions, hydraulic chamber cleaning system will rapidly clean crushing chamber, thus largely shortening downtime.

5. High reliability
This diabase cone crusher is outfitted with main shaft of large diameter, heavy-duty machine rack, standalone oil lubricating system and automatic control system, which greatly improves machine robustness, durability and reliability.

6. Easy operation and maintenance
All components of our cone crusher is demountable from the top or side of the machine, including fixed and mobile cone assembly. Bronze sliding bearing can still retain remarkable bearing capacity under environment of high impact and vibration. What's more, it is more economical and convenient for maintenance than rolling bearing.

7. Split type lubrication
Standalone oil lubricating system adopts split type lubrication to provide dual protection for bearing and realize automatic security protection.

8. Good sealing effect
Our basalt cone crusher makes use of compensating grease sealing to maximally prevent lubricating oil from dust pollution, which also effectively extends service life of components.
