Crusher problems arising from the use

A smelter feed system consists of a conveyor belt feeding, jaw crusher through into the next process. A night shift (0:00 to eight in the morning), Wang workers in this position

is responsible for operating, because the duty of broken chunks of raw materials are more difficult to eat into the crusher encountered

Chunks of ore must stop the ore out, first of its artificial Zacheng pieces with a sledgehammer. Normal operation when feeding shift production tasks completed more than five

hours long, which returned from there two hours after hours on duty until the completion of tasks around 60%. Six o'clock

So, an aniseed into the crusher, linear vibrating screen operator Wang saw just kept idling, ore no go, they put a belt conveyor stopped, walked straight up to the crusher feed opening, left

foot on the console edge, right hard to step crusher ore feed port. Final stones

To be squeezed in, but because of too much force Wang, right foot into the crusher, all of the following folders broken ankle.

Direct cause

Wang illegal operation. In order to complete the shift of production tasks, anxious. In accordance with the procedures specified crusher plant, crusher is jammed material must

stop processing. And Wang did not take measures to stop treatment, but with the foot lump ores, resulting in the accident

Happen.

Indirect causes

1, the plant safety management lax. Wang Failing to wear protective shoes to work, duty squad discovery of this situation has not put a stop to.

2, employee safety awareness is weak. Wang if this accident a little more than self-protection awareness, completely avoid the accident.

3, heavy production does not result in the heavy security is also one of the reasons the incident occurred.

Responsibility

The plant safety authorities and through the accident scene investigation and analysis of the operating environment, decided that this was man-made accidents. Wang primary

responsibility for the accident, neglect of duty squad management is also due for the accident can not shirk responsibility. Responsibility for two people into the plant

Line treatment: Wang has constituted serious injuries, no longer do economic sanctions, to be recovered 30 days after the stoppage reflect and write a written guarantee. Duty

squad were treated with removal treatment.

Precaution

1, to strengthen safety knowledge training and education, enhance the safety awareness of workers, improving their safety skills and self-protection capabilities.

2, increase the production site safety inspection efforts to prevent illegal operations, illegal command.
