Material classification and screening is the core link to ensure product quality in mining, building materials production, power energy and waste disposal industries. Traditional screening equipment often restricts production efficiency due to screen blockage, high energy consumption and complex maintenance, while shaftless drum screen, with its unique design and performance advantages, has become the key equipment to solve this pain point. As a new generation of screening Technical Delegate, shaftless drum screen redefines the efficiency and reliability of industrial screening through structural innovation and process optimization.
I. Structural Innovation: Shaftless Design Breaks Through The Traditional Limitations
The core innovation of shaftless drum screen is to abandon the traditional central shaft structure and use external support and drive system to realize drum rotation. This design solves the risk of large materials winding around the axis, and is especially suitable for the treatment of belt-shaped, soft or easily winding materials, such as plastic bags and fibrous impurities in domestic garbage. The inside of the drum adopts a split screen structure, and the size of the screen mesh can be customized according to the needs, covering a range of 3mm to 200mm, to meet the needs of multi-level screening from fine powder to lumps.
The support system adopts an integral through shaft structure and a composite rubber roller, which not only ensures the running stability, but also controls the noise below 65 decibels, which is far below the 85 decibel level of the vibrating screen.
II. Performance Advantage: Screening Solution With Low Consumption
1. Anti-clogging ability is significantly improved
When the traditional vibrating screen is used to process materials with a moisture content of more than 15%, the blockage rate of the screen is as high as 40%, while the shaftless drum screen makes the particles stuck in the screen holes fall off automatically through the centrifugal force generated by the rotation of the drum and the rolling effect of the materials. The experimental data show that the continuous operation time of shaftless drum screen is three times longer than that of vibrating screen, and the screening efficiency is increased by 35% when dealing with coal slime with 22% moisture content.
2. Reduce both energy consumption and maintenance costs
Compared with the vibrating screen, the shaftless drum screen with deceleration transmission system can reduce the energy consumption per unit output by 40%. Taking a sand and gravel yard with a daily processing capacity of 2000 tons as an example, the annual power saving can reach 120000 degrees. In terms of maintenance, the split screen design shortens the replacement time from 4 hours of traditional equipment to 30 minutes, and reduces the cost of spare parts by 60%.
3. Adaptability and productivity advantages
Shaftless drum screens can handle materials ranging in hardness from 5 to 8 on the Mohs scale, covering a wide range of materials from limestone to iron ore. In the application of a gold concentrator in Shandong Province, the screening capacity of 150 tons per hour is achieved by a single device, which is equivalent to the total capacity of five vibrating screens. Its fully sealed structure effectively controls the diffusion of dust and meets the environmental protection standards, so that enterprises do not need to invest additional dust removal equipment.
III. Application Scenario: Screening Experts Covering Multiple Industries
1. Energy and Metallurgy
In the thermal power plant, the shaftless drum screen can divide the raw coal into three grades of 0-10 mm, 10-50 mm and 50-100 mm according to the particle size, so as to optimize the combustion efficiency and reduce the fly ash content. The application case of a group shows that the uniformity of sinter particle size is improved by 28% and the utilization coefficient of blast furnace is increased by 0. 3t/ (m ³ · d) after using shaftless drum screen.
2. Building Materials and Chemical Industry
In the aggregate production line, the shaftless drum screen divides the gravel into 5-10 mm, 10-20 mm and 20-31.5 mm specifications through multi-stage screening, and the qualified rate of product grading is increased from 82% to 97%. In that production of chemical fertilize, the screening precision of the fine pow below 3mm reaches 99.5%, and the caking phenomenon is effectively prevented.
