Household Municipal Solid Waste Sorting Equipment is a type of equipment that is mainly used for sorting waste in residential and commercial premises. It can also be used for sorting solid waste in landfills. The type of equipment that is used in this process is divided into three categories, namely the Rotary screening machine, the Comprehensive winnowing machine, and the Disk screeners.
Disk screeners
A disk screener is a waste sorting equipment that separates processed MSW into two fractions. This is done by allowing smaller components to fall through the screen and allowing larger components to migrate across it.
The disc screener has been developed in order to achieve precise separation of waste. Accurate separation of the material prevents contamination of the end product and minimizes dirt buildup on the equipment.
Typical materials processed are sawdust, shavings, board furnish, trim ends, and mulch. In addition to these, the following wastes are researched and studied: cement kiln dust, rice husk ash, and fly ash. These materials are not only useful in the recycling process, but are also used in construction and demolition (C&D) activities.
The rotational motion of the discs minimizes the possibility of clogging. Additionally, the flexible screen hole has a self-cleaning function. The patented disc screen from JONO has been proven in over 100 projects to be effective in separating organics from municipal solid waste.
Rotary screening machine
A rotary screening machine is a kind of mechanical screening device, which is mainly used in solid waste treatment. Its main function is to separate materials by particle size. The screen can be divided into two types, namely vibrating screen and rotary screen.
During the separation process, the materials are classified into three categories. One is under layer, which contains small organic wastes, earth, and other materials. Another is upper layer, which includes plastic, metal, and other materials.
The capacity of a trommel screen depends on the size of its screen. Screen size can range from 50 mm to 100 mm. This enables multiple separations.
Trommel screen is the most common type of screening equipment. It is used in many solid waste treatment lines. In addition, it can also be applied to mineral processing. If you are considering trommel screens for your line, you should know more about its features and its advantages.
Comprehensive winnowing machine
A comprehensive winnowing machine sounds like a piece of equipment that separates light and heavy materials from waste. It sounds like it could be a plausible term but its not one used in waste management circles uses different methods, there are related methods such as cyclone separation, volumetric separation, and bouncing separation, but winnowing is not a term used in connection with MSW sorting.
There are nevertheless many machines which are designed to sort household municipal solid waste. They can separate a variety of materials, such as plastic, metal, and combustibles. The whole process is designed to achieve maximum recycling of recyclable waste.
Firstly, the trash is transported by a belt conveyor. A uniform feeder is installed to ensure the proper feeding of the material. Next, the waste is sent to a rotary screening machine.
Once the waste reaches the rotary screening machine, it is separated into two layers. The upper layer contains lighter, non-ferrous materials, such as plastic, paper, and rubber. Lower materials include solid, earth, and small organic waste.
After separating the rubbish, the lighter waste goes to a hydraulic depackaging machine. Meanwhile, the heavier material will be sent to further processing.
Digital or "smart" waste management solutions
One way of addressing this issue is by developing smart waste management solutions. These systems are based on the Internet of Things (IoT) and involve a wide range of sensors, which gather data and optimize processes.
The technology allows city waste authorities to reduce the amount of solid waste being disposed to landfill. It can also help in tracing incoming loads of waste and identify types of waste. In addition, it can help with onsite waste separation.
This is achieved through the integration of materials detection sensors into bins. Artificial intelligence can be used to recognize materials, and robotic automation can be used to sort the waste. Eventually, the data generated can be used to teach the system to operate more accurately with improve improved AI.
Other digital technologies include artificial neural networks, which can be used to analyze and forecast the waste disposal process. Similarly, the use of mobile devices can be used to gather waste-related data from the public. Data analytics can then turn that information into valuable insights.
