1. Driven by dual motors, the screening accuracy is significantly improved, achieving the balance between output and precision.
2. The dual-motor shaftless trommel screen is constructed with thickened Q355B high-strength structural steel plates. Compared with ordinary structural steel, it offers higher strength, better wear resistance, excellent toughness, and a longer service life.
3.The shaftless design greatly reduces faults such as bearing damage and machine jamming, avoiding material accumulation and poor screening—thus enhancing screening efficiency.
4.The trommel screen’s drum is made of 201 stainless steel, featuring good corrosion resistance and an extended service life.
The dual-motor shaftless trommel drum screen is a specialized equipment designed for efficient material grading through a shaftless drum structure and dual-motor drive.
It is widely applied in mining, coal washing, aggregate screening, construction waste recycling, and renewable resource sorting, adapting to diverse industrial scenarios.
Featuring anti-blockage performance, adjustable mesh for precise classification, durable design, and low energy consumption, it suits both small and large-scale production needs.
Working Principle
The dual-motor shaftless trommel screen drives the drum to rotate through two motors, which are distributed on both sides of the equipment. A synchronous controller ensures the two motors operate synchronously—this design guarantees power balance, reduces uneven loads, and improves the equipment’s operational stability and efficiency.
The motor transmits power to the drum via a reducer, making the drum rotate slowly around its axis. As the drum rotates, materials move forward along the screen inside the drum and are screened under the action of gravity and centrifugal force.
The shaftless design allows materials to flow more smoothly in the drum, reduces clogging, and further enhances screening efficiency.
Core Advantage Of RUIJIE Shaftless Design
1. Eliminates Central Shaft
Traditional trommel screens are usually equipped with a central shaft, while the shaftless trommel screen removes this component. The drum relies entirely on the external support frame and motors for rotation.
2. More Open Screening Space
The shaftless design makes the internal screening space of the drum more open. Materials are no longer blocked by the central shaft and can roll and disperse more freely in the drum.
3. Reduces Clogging & Winding
Especially when handling high-moisture, strong-viscosity, or fibrous materials, the shaftless design prevents materials from winding around or accumulating on a shaft, reducing clogging.
4.Improves Screening Efficiency
Without interference from a central shaft, materials can be fully rolled and dispersed during screening, greatly improving screening efficiency.
Comprehensive Performance
Dual motors provide enhanced power output and stability, while the shaftless design reduces material entanglement and clogging, improving screening efficiency.
This design enables the equipment to adapt to a wide range of materials, especially high humidity, viscous or fibrous materials, which are widely used in industries such as mining, construction, waste treatment, etc.
The Dual-Motor Shaftless Rotary Drum Screen is used for material particle size classification and is widely applied in industries including mining, building materials, solid waste sorting, scrap metal sorting and recycling, as well as incineration bottom ash (IBA) sorting plants.
1. In the Stone Yard: Rotary Drum Screening Machine is used for grading large & small stones and separating soil & stone powder. It is used to separate sand & gravel in sand and gravel yards.
2. Coal Industry:Shaftless Drum Screen is used for separating lump coal & pulverized coal and coal washing in the coal industry (components of coal washing machinery).
3. Incineration Bottom Ash (IBA) Industry: Shaftless drum screen machine can be used to screen out iron lumps of different sizes from incineration bottom ash, which has achieved the purpose of full recycling.
4. Garbage Separation:It is widely used in household waste sorting. Larger items such as plastic bottles, paper, etc., will move along the upper part of the screen to the discharge end because they cannot pass through the screen hole; Smaller particles, such as sand and soil, can pass through the sieve hole and fall into the collection device at the lower part of the drum.
