Disc Screens

The disc screen consists of a screening surface formed by multiple shafts, each fitted with staggered discs. These shafts are driven by electric motors via chain or gear transmission systems and rotate in the same direction as the material flow. The synchronized rotation facilitates both uniform material conveyance and effective size separation.
This screening equipment is especially well-suited for processing bulk materials such as coal, coke, ore, and limestone. It is extensively used in open-pit mining, coal handling systems within thermal power plants, as well as in the metallurgical, chemical, and building materials industries.
How IT WORKS
The disc screens is composed of several parallel arranged screen shafts, which are arranged along a specific trajectory. A certain number of specially-shaped screen plates are installed on each shaft. The screen plates rotate in the same direction at the same speed along with the shafts, forming a rolling arc-shaped screening surface. When materials flow on this surface, they can form a uniform thickness and have a certain acceleration material flow. Large particle materials are gradually conveyed forward under the push of the rotating screen plates and enter the crushing equipment; small particle materials pass through the screen holes and fall into the material collection device, thus achieving the screening purpose.

features:
1. Compact Design and Efficient Space Utilization
The integrated compact structure of this disc screen requires a small footprint, has a high space utilization rate, and allows for flexible equipment layout.

2. Low Maintenance and Operating Costs
Durable discs and rotor shafts reduce wear, lower maintenance requirements, and extend operating time.

3. High Screening Efficiency
Through rotational movement, the disc screen separates materials by particle size, improving continuous material classification and system efficiency.

4. High Processing Capacity
This disc screen is designed for high-throughput operations, increasing the screening area and enhancing production capacity.

5. Wide Application
The disc screening machine is suitable for wet, sticky, and difficult-to-screen materials, performing well in waste management, resource recovery, and mining industries.

6. Self-Cleaning and Anti-Entanglement
The rotating discs prevent clogging and entanglement, and the comb-shaped plates ensure efficient cleaning, minimizing downtime.
CORE COMPONENT
The disc screen is mainly composed of screen box, protective housing, driving device, screen shaft assembly,self-cleaning device, Wear-resistant lining plateetc etc.
Screen Shaft Assembly

The screen shaft assembly, composed of a motor, reducer, shafts, discs, and bearings, ensures stable power transmission under heavy loads. Its high-strength design resists bending and fatigue, maintaining continuous operation even if one shaft fails. Externally mounted bearings simplify maintenance and enhance reliability for mining, coal, and aggregate screening.
