Solid waste refers to waste generated in production, life and other activities that cannot be reused or directly discharged. Due to their different properties, solid waste is divided into two categories: hazardous waste and non-hazardous waste. Hazardous waste mainly includes waste batteries, waste fluorescent lamp tubes, expired medicines, waste paint, waste film, waste pharmaceutical packaging, etc.; non-hazardous waste covers various types of domestic waste, construction waste, waste paper, plastic products, etc. The crushing and processing of solid waste is a common waste treatment method.
Solid waste crushing processing refers to the crushing, crushing, grinding and other processing of waste through mechanical equipment to turn it into smaller particles or powder to facilitate subsequent classification, packaging, transportation and processing. This treatment method can effectively reduce the volume of waste, reduce storage and transportation costs, and is conducive to resource recycling and environmental protection.
The solid waste crushing process mainly includes the feeding of materials, the operation of crushing equipment, the discharging of products, and the maintenance of equipment. In the feeding process, solid waste must be pre-treated, including removing impurities and sorting recyclables. The operation of crushing equipment is the core step of the entire process. Commonly used equipment include crushers, pulverizers, mills, etc. Different equipment can be selected according to different waste properties. In the discharging process, the product must be screened to classify particles of different sizes. Equipment maintenance is very important. Regularly check the wear and tear of the equipment and replace wearing parts in time to ensure the normal operation of the equipment.
The crushing processing of solid waste can be used in many fields. First of all, it can be used for the treatment of domestic waste. After crushing the garbage, the volume of the garbage can be reduced, the landfill area and siltation can be reduced, and recyclable items can also be separated for reuse. Secondly, it can be used for the treatment of construction waste. After construction waste is crushed, fine-grained aggregates can be obtained, which can be used again in the production of building materials. In addition, the crushing and processing of solid waste can also be used in the production processes of chemical, pharmaceutical, electronics and other industries. For example, waste plastics can be crushed to obtain recycled materials, which can be used again to produce plastic products.
In short, solid waste is a kind of waste that cannot be avoided in human activities. The crushing process of solid waste is a common waste treatment method, which can effectively reduce the volume of waste and facilitate subsequent classification and processing. The crushing and processing of solid waste can be used in many fields and is of great significance to resource recycling and environmental protection.
