Municipal solid waste disc screen is an efficient and stable sorting equipment, suitable for urban demolition and renovation projects and large-scale construction waste storage plants where solid waste and construction waste are processed.
- The equipment adopts a combined structure of staggered screen discs to precisely control the screening gap and efficiently separate solid waste materials such as domestic garbage and construction waste with particle sizes smaller than the set standard. The processing capacity is four times that of traditional drum screens of the same volume, and the screening efficiency is twice that of drum screens.
- The entire machine is driven by an electric motor and operates synchronously and at a constant speed for multiple screen shafts. The screen discs on the shafts continuously rotate and stir the surface garbage, relying on the fixed gaps between the screen discs and the self-weight and particle size of the materials to complete the classification of coarse and fine materials. Different numbers of screen shafts can be installed according to the required screening processing volume.
- In response to the pain points of municipal solid waste, such as high humidity and high viscosity, which make it prone to clogging and blocking, a self-cleaning device is configured under the screen discs and a continuous dynamic rotation design is adopted to fundamentally avoid the adhesion and blockage of the screen gaps, completely solving the problems of material clogging, hole clogging, and frequent machine shutdown for cleaning when processing wet garbage on ordinary screen surfaces. It can stably achieve continuous and efficient screening operations of various municipal solid wastes such as domestic garbage, construction waste, and decomposed garbage.
How Municipal Solid Waste Roller Screen Work?
When municipal solid waste is uniformly conveyed onto the screen surface of the equipment, the motor drives the screen shaft to rotate. Due to the presence of gaps between the screen shafts and the rotational direction and speed of the screen shafts being adjustable, fine particles such as sand, stones, and soil, which are smaller than the gaps, will fall through the gaps of the screen shafts, while large blocks of materials such as bricks and concrete blocks will be continuously moved forward by the screen shafts, thereby achieving the screening and classification of solid waste of different particle sizes.
Municipal Solid Waste Roller Screen Core Components
Our company has skilled technical workers and perfect quality management system, to ensure the high quality of the core components of the wobbler feeder crusher, to provide a guarantee for the high-performance operation of the product.
Screen Shaft Assembly
- The screen shaft assembly consists of a drive unit motor + reducer, screen shaft, screen disc, flat key, locking nut, coupling, bearing housing and bearing housing accessories. The drive motor and reducer are connected to the screen shaft through the coupling.
- The screen shaft is made of forged 42CrMo material. It undergoes CAE force analysis and is designed to be reasonable and safe, effectively avoiding phenomena such as bending or fracture of the tooth roller shaft. The screen shaft seal uses a special rubber bowl seal to prevent dust from spilling out.
- When any one of the screen shafts fails, the material can be pushed by the previous screen shaft and continue to advance beyond the faulty screen shaft, ensuring the normal operation of screening.
- The screen shaft bearing housing is installed on the outer side of the screen side plate and is convenient for disassembly.

Screen Disc
- By using small inclined roller screen discs, while ensuring the screening particle size, the disturbance ability of the roller screen discs on the stone flow is maximized, thereby increasing the screening throughput rate.
- By adopting an interlaced arrangement of roller screen discs, the design is more reasonable and novel.
- Using an integral casting of wear-resistant manganese-chromium alloy steel, it can easily withstand the impact and wear of materials smaller than 800mm, without any deformation or fracture. The surface hardness of the screen disc is HRC55, with excellent wear resistance, and the service life is not less than 12,000 hours.



Municipal Solid Waste Roller Screen Structure
The roller screen is mainly composed of the drive device (including the motor, reducer, coupling), the screen shaft assembly (including the screen shaft, screen disc, etc.), the screen body, the observation door, the wear-resistant liner plate, and the self-cleaning device, etc.


Drive Device
It adopts single-axis single-motor drive or multi-axis chain combination transmission mode, reasonable power configuration and screen surface structure to evenly distribute the material load in the screen and ensure smooth operation.
The design structure of the driving device is simple, easy to install and disassemble, and the connected screen shaft is not moved when disassembling.
The driving device is compact in size, light in weight, long in life and low in maintenance cost.

Screen Disc
The municipal solid waste roller screen disc is arranged in an alternating pattern, which makes the design more reasonable and resistant to impact. There will be no deformation or fracture at all.
The parabolic-shaped screen disc is well-designed, with high assembly accuracy. It can increase the screening rate and improve the screening accuracy. It has excellent wear resistance and a long service life.

Screen Box
The main body of the municipal solid waste roller screen is welded with low-alloy high-strength structural steel. All screen shaft assemblies are fixed to the machine body through connecting bolts. Wear-resistant lining plates are installed on the side of the machine body to avoid direct contact between materials and the box, greatly extending the service life of the equipment. And the wear-resistant lining plate and the screen box are connected by bolts, which is easy to replace.

Protective Housing
The protective housing of the municipal solid waste roller screen is welded with NM500 wear-resistant alloy steel plate, sprayed with anti-rust and anti-corrosion paint, and connected with the hopper and the outlet housing at the front and back.
The overall sealing of the screen box can effectively prevent dust pollution, reduce the impact on the environment, and meet the requirements of green construction.
The protective housing is provided with an observation window to facilitate the observation of the operation of the machine.

Wear-Resistant Lining Plate
The wear-resistant lining plate is made of alloy material, and the whole production process adopts welding, heat treatment, machining and other assembly line production, which has a long service life and strong wear resistance, toughness and impact resistance.
The inside of the screen box and the contact surface between the guide groove and the material are provided with wear-resistant lining plates, which can protect the screen box and increase the life of the guide groove. The lining plate is fixed together with the mother plate by bolts, and the replacement is convenient.

Self-cleaning Device
The self-cleaning device of the screen shaft is made of wear-resistant steel and is equipped with a cutting edge, which is inclined to the lower part of the screen shaft. Some fibrous debris and sticky materials attached to the screen will be automatically cleaned off by the cleaning device to solve the blockage of the screen surface.
Municipal Solid Waste Roller Screen Features
No Blockage Of Sieve Holes
Due to the continuous operation of the screen disc on the screen shaft of the equipment, and the installation of self-cleaning devices below each screen shaft, wet domestic waste and muddy construction waste will not adhere and get stuck in the gaps of the screen shaft. Unlike traditional vibrating screens and drum screens with static screening surfaces, which are prone to blockage of sieve holes and require frequent shutdown for cleaning, this equipment can continuously process municipal solid waste with high moisture content and high viscosity.
Not Prone To Tangling
Our municipal solid waste roller screen adopts an interlaced layout of small oblique-angle screen discs. Plastic bags, cloth strips, and fibrous soft waste are less likely to get tangled and stuck on the screen shaft. Compared with drum screens, it significantly reduces the time required for manual removal of tangled debris and lowers the operating and maintenance costs.
Durable And Impact-Resistant
Our screen discs of the roller screen are made by casting manganese-chromium alloy steel as a whole. They can withstand continuous impacts from concrete blocks, stones, and waste materials, and are unlikely to undergo any deformation or fracture. The entire machine's load-bearing frame is welded with Q355D low-alloy high-strength structural steel, which has high strength. It is also unlikely to damage the equipment when transporting mixed solid waste such as steel bars, bricks, and plastics over a long period.
Continuous And Efficient Operation
Our roller screen can operate continuously for 24 hours without interruption. It has a large processing capacity and will not stop due to wet garbage or tangled soft materials getting stuck, making it highly suitable for the large flow requirements of waste transfer stations or pre-treatment lines, ensuring the continuous operation of the entire screening process line.
Environmental Protection
The screening is accomplished through the low-speed rolling of the screen shaft. There is no high-frequency vibration. The box body is designed with a fully enclosed structure, which can effectively suppress the diffusion of solid waste dust. During operation, the noise is very low, fully meeting the requirements of environmental control in urban waste treatment areas. It will not cause a large amount of dust to pollute the surrounding environment.
Structure Simple
Components such as the screen shaft and screen disc are designed in a modular manner. Once worn out, they can be easily replaced, reducing downtime and lowering the maintenance cost of the equipment.
