How to operate a crushing plant safely?

There are several tips regarding quarry safety as follows:

Dust and Fumes
The by-products of blasting rock can present serious safety hazards. Quarries use harsh chemicals to process rock, the fumes of which can be inhaled. Fumes and dust impair worker health, and sometimes the health of neighbors. It is important to minimize these risks.

Noise
Noise isn't just an inconvenience; it can also harm people's hearing and add to people's stress. It can also lower the property values in the neighborhood. Quarry inspectors work to make sure procedures are in place to keep quarry noise to a minimum.

Electrical
Electrical inspections must be conducted regularly—some as frequently as once a quarter. Inspectors check for correct installation, grounding, voltage, and wire flexibility. In addition, explosives must be checked since they are set with an electrical charge. All electrical equipment must be properly maintained, and workers must be current on operating licenses and proper use of electrical items.


Overheat faults of jaw crusher and its solutions

When the jaw crusher is working, sometimes there will be too much heat in bearing bracket and swing jaw plate, and that may be caused by these following factors:

1) The bearing bracket is lack of oil or there is too much oil
2) Oil hole clogging causes lubrication failure
3) Balancing weight of flywheel and grooved pulley badly centered, unusual vibration of frame
4) Damaging of bearing or mounting brackets
5) Frictional heating between seal-off bushing and swing jaw plate end cap; or eccentric shaft sealed cap rotate with main shaft, causing frictional heats

To solve the above problems, the workers should:

1)    Do oil lubrication according to instruction manual recommendations;
2)    Clean oil hole and oil sink;
3)    Rebalance balancing weight;
4)    Replace the bearing;
5)    Replace swing jaw plate's end cap and seal off bushing; or loosen upper bearing cap of frame bearing bracket; press fuse and eccentric shaft sealed cap into bearing brackets mounted on frame, and fix bearing cap to remove rotation of eccentric shaft sealed cap.
