With the acceleration of urbanization, the disposal of construction waste has become an important environmental protection issue. Impact crusher is widely used in construction waste treatment because of its efficient crushing performance and adjustable discharge particle size. In this process, as the key vulnerable parts of the impact crusher, the plate hammer and the buffer plate have unique characteristics.
1. High wear resistance requirement
Construction waste usually contains concrete blocks, masonry, metal fragments and other high hardness materials. These materials wear the hammer and buffer plate very seriously during the crushing process. Therefore, the board hammer and buffer plate used in construction waste treatment need to have higher wear resistance. High chromium cast iron and high manganese steel are common material choices, which are able to maintain a long service life in high impact and high wear environments.
2. High strength and toughness balance
In the treatment of construction waste, the board hammer and buffer plate must not only withstand the impact of high-hardness materials, but also maintain the integrity of the structure under frequent impact. Therefore, the selection of materials needs to strike a balance between high strength and high toughness. High manganese steel is suitable for crushing environment with high impact force because of its good toughness and work hardening characteristics. High chromium cast iron is the ideal material for hammer head because of its high hardness and excellent wear resistance.
3. Frequent replacement and maintenance
Due to the complexity and high wear of construction waste, the replacement frequency of plate hammer and buffer plate is high. In order to ensure the efficient operation of the crusher, regular inspection and replacement of wearing parts is necessary. It is recommended to check the wear of the hammer and buffer plate regularly during use, and replace them in time according to the actual wear degree. At the same time, in order to extend the service life of the wearing parts, reasonable adjustment of the crusher’s operating parameters, such as feed speed, material granularity, etc., is also an important maintenance measure.
4. Environmental protection and sustainability
Environmental protection and sustainability are important considerations in the disposal of construction waste. Choosing high-quality, wear-resistant mallets and buffer boards can not only reduce the frequency of replacement, reduce maintenance costs, but also reduce dust and noise pollution caused by wear and tear of wearing parts. In addition, the application of some new materials and processes, such as composite casting process, can improve the performance of wearing parts, reduce resource waste, and meet the requirements of environmental protection and sustainable development.
5. You’re adaptable
The composition of construction waste is complex, and different sources of waste may contain different proportions of concrete, masonry, metal and other materials. Therefore, the plate hammer and buffer plate need to have good adaptability and can cope with different hardness and particle size of the material. Through reasonable design and material selection, the versatility and adaptability of wearing parts can be improved, so that they can maintain good performance in different types of construction waste treatment.
Sum up
In construction waste treatment, the use of board hammer and buffer board has the characteristics of high wear resistance, high strength and toughness balance, frequent replacement and maintenance, environmental protection and sustainability, and strong adaptability. Choosing the right material and design, reasonably adjusting the operating parameters of the crusher, and regular maintenance and replacement are the key to ensuring the efficient operation of the impact crusher, reducing maintenance costs and reducing environmental pollution.
