Component Sieving Machine(Trommel Screen)
A trommel screen is a sieving device that utilizes the inclined and rotational motion of a drum unit to grade materials. It finds extensive applications across multiple industries, including mining, building materials, chemicals, and coal.
Aplication:Mining and Building Materials,Coal and Chemical Industries,Agricultural By-products and Environmental Protectio.etc.
Main Part: Basic Structure: It consists of a drum unit, frame, drive system (motor, gear reducer), inlet and outlet ports, with some models featuring a sealing cover.
Core Components: The drum unit is installed at an incline on the frame and can be equipped with spiral blades or specially designed screens inside. The drive system rotates the drum via a coupling.
Product Description
A trommel screen is a sieving device that utilizes the inclined and rotational motion of a drum unit to grade materials. It finds extensive applications across multiple industries, including mining, building materials, chemicals, and coal. Its core advantage lies in effectively addressing the screen mesh clogging issues that traditional sieving equipment (such as circular vibrating screens and linear screens) often encounters when processing relatively wet materials, thereby significantly enhancing the throughput and reliability of the sieving system.
Main Components
Basic Structure: It consists of a drum unit, frame, drive system (motor, gear reducer), inlet and outlet ports, with some models featuring a sealing cover.
Core Components: The drum unit is installed at an incline on the frame and can be equipped with spiral blades or specially designed screens inside. The drive system rotates the drum via a coupling.
Main Application
Mining and Building Materials: Stone grading, sand-gravel separation, silica/feldspar screening.
Coal and Chemical Industries: Lump coal and coal powder separation, coal washing processes, classification of bulk materials.
Agricultural By-products and Environmental Protection: Material impurity removal, waste sorting, separation of soil and stone powder.
Working Principle
After entering the drum, materials are flipped and rolled due to the drum’s inclination and rotation. Qualified materials (undersize products) pass through the screen and are discharged, while unqualified materials (oversize products) are discharged from the end of the drum. Under the centrifugal force and jigging action within the drum, materials stuck in the screen openings can be ejected, preventing clogging.
Product Advantages
1. Screen Clog Resistance: Specialized screens combined with material tumbling motion adapt well to damp and sticky materials.
2. Efficient and Stable Operation: Low noise, simple structure, easy maintenance, high overall reliability, and low initial investment.
3. High Screening Efficiency: Shaftless models enhance screening time through spiral blade design, while traditional models extend service life with wear-resistant screens.
