Coal gangue is a solid waste discharged from coal mining and washing and processing. my country's coal gangue has accumulated more than 5 billion tons, and it is still increasing at a rate of 300 to 350 million tons per year...
Red mud is a solid waste discharged by alumina enterprises. It pollutes, occupies land and costs money all the year round. It has become a stubborn disease that cannot be cured for a long time. The annual discharge of red mud in my country exceeds 70 million tons, and the cumulative stockpile is more than 500 million tons. The stockpile exceeds 200 million tons...
The overall goal of sludge treatment and disposal in my country is to achieve sludge reduction, stabilization, harmlessness, and resource utilization...
China is a big coal-producing country, and the national policy of using coal as the basic fuel for electricity production will not change for a long time. Burn 1 t of raw coal to produce 250-300 kg of fly ash. The average comprehensive utilization rate of fly ash in my country is 70%, which is mainly used in the building materials industry. Under the national background of "carbon peak" and "carbon neutrality", the problem of fly ash solid waste disposal is prominent...
In 2020, the amount of construction waste in my country has reached 2.6 billion tons. The annual amount of construction waste in my country is about 1.8 billion tons. From the perspective of resource utilization, the overall recycling rate of construction waste in my country is less than 10%, far lower than 90% in Europe and the United States and 95% in Japan and South Korea. The treatment method is still in the extensive landfill and stacking stage...
Tailings are components with low content of useful components produced in beneficiation operations that cannot be economically used for industrial production at present, and are also the main components of industrial solid waste. At present, the output of metallic ores, non-metallic ores, coal and clay produced in countries around the world is huge every year, and the amount of tailings produced therefrom is also quite large.
Production line introduction: In terms of sludge disposal, we actively develop and improve processes, successfully integrate metallurgy, chemical industry, and building materials processes, and develop energy-saving and environmental protection equipment suitable for ceramsite production lines. The construction of a new type of environmentally friendly and energy-saving ceramsite opens up a new process route.
Capacity:50,000-600,000(m³/a)
Calcination temperature:1100-1200℃
Main raw materials: Municipal sludge, domestic sludge, river dredging sludge, pickling sludge, printing and dyeing sludge, electroplating sludge
Production line introduction: Clay ceramsite is made of clay with suitable composition. When the composition is not suitable, some other materials need to be added. artificial lightweight aggregate. After years of research and development, energy-saving and environmental protection equipment suitable for ceramsite production line has been developed, which has opened up a new process route for the construction of new environmentally friendly and energy-saving ceramsite.
Capacity:50,000-600,000(m³/a)
Calcination temperature:1100-1200℃
Main equipment: Plug-in rotary kiln, single cylinder cooler, vertical cooler, air cooler, roller crusher, double shaft mixer, double roller granulator, bag filter , fan, rotary screen, belt conveyor
Production line introduction: Fly ash is waste discharged from thermal power plants, and sludge can be waste discharged from urban water treatment plants or sludge at the bottom of rivers and lakes. After the fly ash, sludge and clay are mixed and aged, they can be granulated and fired into building ceramsite, so that the solid waste can be effectively used. The clay is only used as a binder. After years of research and development, a suitable ceramsite production line has been developed. The energy-saving and environmental protection equipment used has opened up a new process route for the construction of new environmentally friendly and energy-saving ceramsite.
Capacity:50,000-600,000(m³/a)
Calcination temperature:1100-1200℃
Main equipment: Plug-in rotary kiln, single cylinder cooler, vertical cooler, air cooler, roller crusher, double shaft mixer, double roller granulator, bag filter , fan, rotary screen, belt conveyor
Production line introduction: Shale ceramsite is made from natural rock shale after crushing, screening, preheating and roasting. It is non-toxic, odorless, compressive and wear-resistant, corrosion-resistant, and has good adsorption performance and strength. Various types of water purification and soilless cultivation of flower bonsai. After years of research and development, energy-saving and environmental protection equipment suitable for ceramsite production line has been developed, which has opened up a new process route for the construction of new environmentally friendly and energy-saving ceramsite.
Capacity:50,000-600,000(m³/a)
Calcination temperature:1100-1200℃
Main equipment: Jaw crusher, single-cylinder rotary kiln, single-cylinder cooler, air cooler, bag filter, fan, rotary screen
Production line introduction: Contaminated soil is the waste produced by modern industrial production. Due to unorganized discharge or failure of the discharge system, it penetrates into the soil layer, resulting in changes in the physical, mechanical and chemical properties of the soil. , directly affect engineering activities or be harmful to human health, animal reproduction, plant growth, etc. With the implementation of my country's environmental protection policy, as a solid waste, how to achieve harmless, resourceful and stable disposal of contaminated soil is unanimously explored by everyone.
Our experimental center, through the analysis of polluted soil and continuous small and pilot tests, has explored a way to burn ceramsite with a rotary kiln, and truly realize the harmless, resourceful and stable disposal of polluted soil. change.
Capacity:50,000-600,000(m³/a)
Calcination temperature:1100-1200℃
Main equipment: Plug-in rotary kiln, single-cylinder cooler, vertical cooler, roller crusher, double-shaft mixer, double-roller granulator, stone remover, secondary shaping machine
