1.1 Incoming raw materials
The operators cannot strictly accept the raw materials according to the standards, and there are often large stones, scrap steel and other debris mixed in.
In addition, in the process of preparing raw materials, there is no effective means to remove debris, which leads to the introduction of debris in the process, and ultimately leads to the belt being scratched and failure.
1.2 Process specification
In the daily production operation, there was no strict implementation according to the process procedures. In order to blindly pursue the maximum distribution quantity, the cooling load of the ring cooler was increased, resulting in too high temperature and finally the belt was burnt out.
As the ingredients are affected by various factors, the ingredients appear inaccurate, for example, the fuel ratio in the ingredients is too large, which will also lead to belt failure.
1.3 Equipment
In the process of production, it is not possible to carefully check the equipment and have a good sense of responsibility: First, there is a serious blocking phenomenon, the belt will be stuck, but not timely stop, so that the belt is worn out or pulled out;
Secondly, when the belt deviates seriously but does not adjust in time, it will also lead to wear or tear.
Third, the drum and roller of the belt machine are damaged, and wear out the belt;
Fourth, in the belt machine equipment bolts appear loose phenomenon, or the lining plate welding is not strong enough, so in the operation fell into the belt, leading to the belt was scratched.
1.4 Belt conveyor and belt cementation
As a result of the current production of belt machine manufacturers, therefore, there are often bags, degumentation, cracking and other different quality problems.
In the process of belt cementing, the designated canvas layer was not cut as required by the design, and even the integrity of other canvas layers was affected.
In the process of polishing, the scale problem was not accurately grasped, and the phenomenon of burning appeared.
Not evenly applied cloth glue;
Glue is not reasonable enough, the phenomenon of malposition appeared when agglutinate, etc., can bury safety hidden danger for belt.
