The garbage is resource but put in the wrong place, and it is a big problem troubled countries all over the world. Nowadays, the peak of China’s urbanization makes processing of municipal solid waste more seriously. City is ours. In other words, the city’s health relies on ours maintaining.
Household garbage does harm to environment
Firstly, occupied surface of ground. It occupies precious land resource and human beings living space. And make bad effect on the development of industry and agriculture. A large number of garbage destroy vegetation on the surface of the Earth. This not only influences the beauty of natural environment but also destroys the ecological balance of nature;
Secondly, polluted the environment. Solid waste contains all sorts of poisonous substances. If not be handled properly, it can direct pollute soil, air and water resources. Ultimately, it causes seriously damage to various creatures, including humans;
Thirdly, spreading diseases. Garbage contains a lot of microorganisms. It is the habitat of bacteria, viruses, insects, etc and brings seriously endangers to human health;
Fourthly, leachate of garbage can change soil composition and structure. Hazardous waste harms human health through food chain. Waste destroys soil structure and physico-chemical properties, and decreases the soil fertility and water retention ability.Waste contains heavy and poisonous metals such as pathogenic microorganisms and organic pollutants. Under the rain, these poisons will be brought into water body. Polluted water will be harmful to the survival of aquatic organisms and the opening of water resources;
Fifthly, fine particles with the wind make the air pollution more severely. A large amount of air storage sites give off poisonous gases, rat-infested, mosquito breeding. Let’s just say the more than 100 kinds of volatile organic gases lead to cancer;
Sixthly, smoke-dust pollution. Because of the importance and high content of the carbon atoms, in the process of combustion, polymers become small carbon black. After combustion, garbage will produce smoke-dust which is made of carbon black. With the upward motion of air during the combustion process, smoke-dust spread into the air and eventually fall to the ground;
In major cities and county-level cities, with the rapid development of the national economy and the improvement of people’s standard of living, solid waste has been keeping sustainable growth, and the composition of solid waste has taken place great changes. Bio-organic municipal waste is more than 40%. Recycling of resource materials has reached about 40%, just like paper, plastic, glass, metal, and so on. Landfill is harmful to urbanite water and air, even lead to secondary pollution. In order to keep adaptation of municipal solid waste incinerator, bio-treatment, and sanitary landfill, therefore, our company develops a set of solid waste sorting equipment, which improves the treatment of garbage disposal. It is helpful to waste classification treatment. Some made into nutritional soil as fertilizers for plants and trees. Sorted out plastic can be reused to make plastic granules. Paper can be reused to make pulp and make paper; Glass and iron can be reused, too. This technology not only solves the problem of environmental pollution, but also be recycled. So that garbage is really a treasure. It is national welfare.
Based on the introduction of foreign advanced technology, after doing a lot of investigation and research work, Beston (Henan) machinery Co., Ltd. makes up program about technology of waste sorting equipment and also develop better suited the situation of china. After garbage compression and transfer, we can take bulky waste crushing, classification of garbage sorting and recycling packaging and other supportive measures. Bulky waste can be through bulky waste crushers, sorting, sorted, and further resource pack, such as furniture and electric appliance.
Waste sorting equipment is the mechanical integration of high technology product with first-class design, manufacturing processes, perfect configuration and reliable performance. In addition, the using of the first domestic garbage sorting lines and garbage compactors and docking technology, makes RTS (refuse transfer station) realize waste collection, sorting, compression, and integrated operations of the mode of transport. So the equipment improves waste recovery and utilization of resources and increases the economic, environmental and social benefits of RTS to meet the social needs of waste resource recovery and recycling economy and sustainable scientific development.
Waste treatment is necessary for our generation. With the social development society, differences between urban and rural are getting smaller. The amount of household waste is growing. So the garbage disposal becomes a major issue we have to face in the future. The experts at home and abroad put forward many ideas, like landfill,trash-burning power. If we look at the problem from different perspectives, these measures has many disadvantages.
Landfill: through longer oxidation, the garbage will decompose toxic substances and carcinogens. These will not only make badly significant performance on earth and atmosphere but also have side effects on our future generations.
Trash-burning power: Although it belongs to recycling, its emission brings sever pollution to atmosphere. Moreover, slag maybe lead to secondary pollution or more.’

Description on Operation Flow Chart
This process system feeding way is by forklift will rubbish into the rubbish bin, by receiving hopper bottom plate conveyor jiang is expected to take away, balanced by ejecting device sending material layer dial evenly after the first belt conveyor, through the manual sorting platform, picked out by artificial to big ones, at the same time through strong magnetic magnetic separation, black metal picked out, again by broken drum screen, classification of garbage into the garbage and < 90 mm and 90 mm or more (plug hole size according to the reality of garbage) on the screen, undersize material as raw materials for the system of fat (or landfill) output. ≥90mm sieve material through the sieve material transport conveyor into other devices (or packed storage).
