1. Improving the conveyor belt drop hopper and improving the conveyor belt drop hopper are one of the effective measures to prevent the early damage of the conveyor belt. Improve the falling hopper of each belt conveyor to increase the capacity of passing the foreign object by 2.5 times. The long and large foreign objects are not easy to get caught between the funnel wall and the conveyor belt during the conveying process, and the foreign matter tearing conveyor belt is reduced. Probability; the guide skirt at the falling hopper makes the gap with the conveyor belt run larger and larger along the running direction of the conveyor belt, solving the problem that the coal block and the stone block are caught between the conveyor belt and the skirt, eliminating the resulting Conveyor belt damage. The hopper with large drop is equipped with a buffer baffle inside to prevent the material from directly impacting the conveyor belt.
2. Add a scraping device at the reversing drum, and add a scraping device at the reversing drum along the conveyor belt to eliminate the problem of material bonding at the reversing drum and solve the partial damage of the conveyor belt caused by the roller sticking; ://
3. Improvements in the transition of the conveyor head, tail and intermediate transfer, the transition length and transition mode of the belt conveyor head, tail and intermediate transfer, have a great influence on the service life of the conveyor belt. A reasonable transition design is required, and the wear of the rubber surface of the conveyor belt should be minimized to ensure that there is no folding or intermediate bulging of the conveyor belt, and no material leakage occurs at the blanking place;
4. The belt pulley at the concave transition of the conveyor has been proved to be insufficient. The lateral strength of the steel rope conveyor belt is insufficient. When starting, the pressure belt pulley causes the belt to be partially stressed, resulting in tearing the conveyor belt and pressing the belt pulley. All changed to pressure roller, which can completely solve this problem;
5, large arm frame conveyor belt weight reduction, material system yard stacker arm frame conveyor belt initial service life is very short, weight design is too heavy is the conveyor belt tension is too large, premature cracking aging is important the reason. The weight is reduced on the basis of satisfying the tension of the conveying material of the conveyor belt;
6. The flow direction is adjusted. The flow direction has an important influence on the service life of the conveyor belt. The material flow should be operated in the same direction as the conveyor belt, which can greatly improve the service life of the belt conveyor.
Knife Sharpener has stick shape,it is generally selected from medium carbon steel or high carbon steel with magnet .It is high hardness, more wear-resisting, uniform and fine serrated, with good effect of grinding knife. There are a variety of materials for knife sharpener,such as wooden handle,PP handle,ABS handle, etc.
Knife sharpener also has small and portable shape,it is made of diamond, tungsten steel, ceramics. Its hardness is high,with comfortable handle, easy to carry.It is not only suitable for kitchen use, and suitable for outdoor camping.According to the hardness of knife tools, so the harder the hardness of the knife tools to choose the higher hardness of knife sharpener.
