Application
Trommel screen, also called rotary screening machine or drum screening machine, its core component is a multi-mesh circular screening cylinder. It efficiently classifies hard and inert materials of varying sizes and proportions in mixed solid waste, slashing labor intensity.
Key Applications:
Municipal solid waste treatment (pre-screening for recycling/disposal)
Construction waste recycling (aggregate size sorting)
Mining & mineral processing (ore grading)
Power plants & building materials factories (fuel/raw material classification)
Principle
The working principle of the trommel scrren : waste is fed into the hopper and conveyed to the rotating screening drum. Constant tumbling, impact, and friction inside the drum separate materials by size: small particles fall through the screen holes, while large waste is discharged via the outlet—completing efficient size classification.
Feature
●High Screening Efficiency:TLarge effective screening area enables full material-screen contact, delivering high throughput per unit time.
● Precise Screening Accuracy:Continuous tumbling and rolling of materials inside the drum prevents accumulation and clogging, ensuring consistent screening precision.
● Strong Adaptability: Adjustable drum speed and inclination angle to meet screening needs of diverse materials.
● Easy Maintenance: Simplified structure allows for straightforward upkeep operations.
Structure
This trommel screen features a streamlined, fully enclosed design (fully/semi-enclosed optional), with key components:
Feed Inlet: For material loading
Central Shaft & Transmission: Drives drum rotation
Reducer & Motor: Power system
Bottom Frame: Provides stable support
Discharge Outlet: For material output after screening
