Drum Screening Machine

Drum screening machine is a widely used screening equipment in industries such as fertilizer, mining, building materials, chemical, metallurgy, etc. It plays an important role in industrial production with its unique structural design and efficient screening capacity. A drum screening machine is a device that uses a rotating drum to screen materials. It uses the low-speed rotation of the drum to continuously flip and roll the material inside the drum, thereby achieving material grading and screening. The drum screening machine has the advantages of simple structure, convenient operation, and high screening efficiency, and is suitable for screening materials of various particle sizes.

Composition Structure

Drum: The drum is the core component of a drum screening machine, usually composed of multiple cylindrical mesh screens. The aperture size of the sieve is selected according to the particle size requirements of the material to achieve separation of materials with different particle sizes.

Motor and reducer: a device that provides power to the drum, converting the high-speed rotation of the motor into low-speed rotation of the drum through the reducer to meet the requirements of different material screening speeds.

Support frame: a component used to support the entire drum screening machine, usually made of carbon steel or stainless steel material, with good stability and load-bearing capacity.

Inlet and outlet: The inlet is used to feed the material to be screened into the drum, while the outlet is used to discharge the screened material. The shape and size of the inlet and outlet are customized according to actual needs.

Sealing device: a device used to prevent material leakage and external impurities from entering the drum. Sealing devices usually adopt forms such as mechanical seals or packing seals.

Control system: a system used to control the operating status and parameters of the drum screening machine. Control systems typically include instruments and controllers such as temperature sensors, pressure sensors, and liquid level sensors, which can achieve automated control and remote monitoring.

Working Process

Feeding: The material to be screened is fed into the drum through the feeding port.

Screening: Start the motor and reducer to drive the drum to rotate at low speed on the support frame. The material continuously flips and rolls inside the drum, with materials smaller than the sieve aperture falling through the sieve, and materials larger than the sieve aperture remaining inside the drum to continue flipping and rolling.

Discharge: After a certain period of screening, materials smaller than the sieve aperture are discharged through the discharge port, completing the screening process. Meanwhile, materials larger than the sieve aperture are also discharged from the other side of the drum.

Cleaning and maintenance: After each use, it is necessary to clean and maintain the drum screening machine to ensure the cleanliness and integrity of the equipment.

Advantage

High screening efficiency: The drum screening machine adopts a low-speed rotation method, which allows the material to fully flip and roll inside the drum, thereby improving the screening efficiency.

Wide applicability: The drum screening machine is suitable for screening materials of various particle sizes and can meet the process requirements of different industries.

Simple structure: The structure of the drum screening machine is relatively simple, easy to operate, and easy to maintain and upkeep.

Energy saving and environmental protection: The drum screening machine adopts advanced screening technology and energy-saving design, which can reduce energy consumption and emissions and meet environmental protection requirements.

Easy to operate: The drum screening machine is easy to understand and can achieve automated control and remote monitoring, improving production efficiency and management level.

In summary, the drum screening machine plays an important role in industrial production with its unique structural design and efficient screening capability. In the future development, with the continuous advancement of technology and changes in market demand, drum screening machines will continue to innovate and improve, providing more efficient, safe, and environmentally friendly solutions for the production and development of various industries.
