The disc screening uses the disc to roll to separate material of different size. The gap between the discs can be adjusted to obtain the the material under the screen that meets the discharge size requirements. The material on the screen that does not meet the requirements is returned to crushing machine for re-crushing until the discharge size requirements are met. It is generally suitable for large-scale production lines, it can be configured according to customer requirements.

The disc screen is an industrial screening equipment, mainly used for screening and classifying various granular and powdery materials.
The product structure of a disc screen usually consists of the following main parts:
Central Shaft
As one of the core components of the disc screen, the central shaft is used to install and support multiple discs. It is driven by a power device to rotate the discs, serving as a crucial structure for power transmission and enabling the movement of the discs. Generally, the central shaft is made of high - strength steel to ensure that it will not deform or be damaged during long - term operation.
Discs
The discs are the main screening components of the disc screen. Multiple discs are installed at intervals on the central shaft, jointly forming the screening surface. The discs are made of various materials, commonly including wear - resistant metal materials (such as stainless steel and manganese steel) or high - polymer wear - resistant materials. The surface of the discs can be smooth or designed with special shapes or textures according to different screening requirements to improve the screening effect. The gap size between the discs determines the particle size range of the screening. Different specifications of disc screens will set appropriate gaps according to actual needs.
Driving Device
The driving device includes a motor, a reducer, etc., and is used to provide rotational power to the central shaft. The power of the motor is selected based on factors such as the model of the disc screen, processing capacity, and working conditions. The reducer is used to reduce the speed of the motor and increase the torque to meet the working requirements of the disc screen. The driving device is usually installed on one side or at the bottom of the disc screen and is connected to the central shaft through a coupling to ensure stable power transmission.
Frame
The frame plays a role in supporting and fixing the entire disc screen and provides a mounting base for other components. Generally, the frame is welded by section steels (such as channel steel and angle steel) and has sufficient strength and stiffness to ensure the stability of the disc screen during operation. The design of the frame needs to consider factors such as the installation space of the equipment, the convenience of operation, and maintenance.
Feeding Device
The feeding device is used to evenly convey the materials to be screened onto the screening surface of the disc screen. There are various forms of feeding devices, and common ones include feeding hoppers and chutes. Its design should ensure that the materials can enter the screening surface smoothly and evenly, avoiding material accumulation or segregation, thus ensuring the consistency of the screening effect.
Discharging Device
The discharging device includes an oversize material outlet and an undersize material outlet, which are used to collect and discharge materials of different particle sizes after screening respectively. The position and shape of the outlets are designed according to actual production needs and technological processes to facilitate the subsequent processing and transportation of materials.
Sealing Device
To prevent material flying and dust leakage during the screening process, the disc screen is usually equipped with a sealing device. The sealing device can be installed at the feeding port, discharging port, and various connection parts of the disc screen. Common sealing forms include rubber seals and labyrinth seals to ensure the environmental protection and safety of the equipment during operation.
Adjusting Device
Some disc screens may be equipped with an adjusting device to adjust parameters such as the gap between the discs or the angle of the wind vane (if there is an air - assisted screening function). This allows for flexible adjustment according to different material characteristics and screening requirements, thereby improving the screening efficiency and quality.
Its working principle usually involves that the screening surface is composed of multiple discs installed on the central shaft. When the equipment is in operation, the central shaft drives the discs to rotate and the materials keep tumbling and moving under the action of the discs. Due to the certain gaps and specific movement trajectories between the discs, materials of different particle sizes will be screened out during the movement. Fine particle materials that meet the sieve hole size will fall through the gaps and become undersize materials, while larger particle materials will continue to move on the discs and finally be discharged from specific outlets as oversize materials.
The disc screen has the following characteristics and advantages:
It has a relatively high screening efficiency and is capable of continuously processing a large amount of materials.
Its structure is relatively simple, making maintenance and overhaul more convenient, and the equipment has high reliability.
It has strong adaptability to materials and can handle materials of different properties and different particle size ranges, such as ores, chemical raw materials, grains, etc.
It operates stably, produces relatively low noise, and has a small impact on the working environment.
