With the continuous acceleration of urbanization and the improvement of people's living standards, a large number of Municipal Solid Waste have been reused and reprocessed. The MSW recyclable product line is a new idea to effectively recycle waste. Below, I will make a description of the working process of the MSW recyclable product line.The working process of MSW recyclable production line is roughly divided into four parts: broken bag/crushing, magnetic separation, screening and manual sorting. The bag breaking/crushing in the first part is to break and simply break the bagged materials in the MSW, so as to facilitate the back-end material screening. The second part is magnetic separation, which can effectively adsorb the ferromagnetic metal in the material and is also a part of the profit source. The third part is screening, mainly the effective separation of materials, is an important part of the production line. The fourth part uses the manual sorting platform.

The world produces millions of tons of waste glass annually, but the recycling rate is not high. The recycling and utilization of waste glass can not only reduce the environmental damage caused by its production process, but also solve the problem of difficult treatment after use. Data shows that using recycled glass to regenerate glass can save 10% to 30% of coal and electricity energy, reduce air pollution by 20%, and reduce mining waste exhaust by 80%. Calculated by one ton, the recovery of one ton of waste glass can save 720 kg of quartz sand, 250 kg of soda ash, 60 kg of feldspar powder, 10 tons of coal and 400 kilowatt hours of electricity. After returning one ton of waste glass to the furnace, 20000 500 gram bottles can be regenerated, saving 20% of the cost compared to using new raw materials for production.At present, the treatment methods for subsequent utilization of waste glass after collection are mainly divided into heating type and mechanical type. The heating type uses a high-temperature

Scrap car recycling refers to the entire process of dismantling and recycling or reusing discarded and no longer used car parts, tires, plastics, leather, electronic and electrical equipment, etc. The recycling of scrapped cars starts with the owner of the scrapped car and ends with the final processing company, such as steel mills, tire factories, plastic factories, etc. It may also be a maintenance enterprise that uses remanufactured automotive parts, and the two are connected through four stages: recycling, dismantling, crushing, and remanufacturing.Recycling companies purchase scrapped cars from car owners and sell them to dismantling companies. The dismantling company is mainly responsible for dismantling the parts, tires, plastic, leather, electronic products, car shells, etc. of scrapped cars, and extracting waste oil (to prevent explosion during the crushing process). Remanufacturing companies remanufacture returnable components. The crushing company is responsible for crushing the car body that

Industrial waste is generated in the process of industrial production, which will cause great pollution to the environment if it is not properly disposed of. In recent years, one of the emerging solutions is to make industrial waste into RDF alternative fuel.RDF stands for Refuse Derived Fuel, or "waste as fuel", which is a kind of solid fuel derived from combustible wastes through sorting, crushing, drying and other processes. This fuel is widely used in industry (cement kiln co-disposal, etc.) and in urban heating, power and other fields. The process of producing RDF generally consists of the following steps:Separation: Separating industrial waste so that combustible and non-combustible waste can be treated simultaneously;Breaking: Breaking combustible waste into small pieces for subsequent drying and molding;Drying: The use of drying equipment to dry the broken waste to a certain moisture content below, in order to better mold;Molding: The drying of combustible waste for molding, commonly used molding

The treatment of solid waste usually refers to the process of converting solid waste into suitable transportation, storage, utilization, or disposal using physical, chemical, biological, physicochemical, or biochemical methods. The goal of solid waste treatment is harmless, reduced, and resourceful. The treatment technologies for solid waste mainly include compaction technology, crushing technology, sorting technology, solidification technology, incineration and pyrolysis technology, and biological treatment technology.01. Compaction TechnologyCompaction is a pre-treatment technology that reduces the volume of solid waste, reduces transportation costs, and prolongs landfill life. It is suitable for compacting solid waste that reduces volume, such as cars, cans, plastic bottles, etc., and is usually first used for compaction treatment. Some waste materials that may cause operational problems, such as tar, sludge, or liquid materials, are generally not suitable for compaction treatment. 02. Crushing

As is well known, construction waste can be utilized as a resource. For example, after the demolition of a building, the remaining old asphalt is crushed and screened, and remixed with recycled agents, new aggregates, and new asphalt materials in an appropriate proportion to form recycled asphalt concrete, which is used for paving road surface or base layers. Old bricks and tiles are crushed after being roughly divided, serving as lightweight brick aggregates and can also be made into floor tile materials and cement mixtures. Concrete blocks, which account for about 30% of the total construction waste, are also a valuable part of recycling and cannot be wasted. After being crushed, they are used to produce recycled concrete, recycled cement, or as roadbed materials.Clever, have you also discovered the secret - the resource utilization of construction waste is inseparable from fragmentation and screening.Overall, the recycling of construction waste can be divided into two directions: fixed construction waste
