It features a core processing particle size of 0.063-5mm and a maximum feed particle size of 10mm. With the unique vibration characteristics of high frequency and low amplitude, it solves the pain points of traditional screening equipment such as easy agglomeration, screen blocking and low classification accuracy for fine materials, making it the preferred equipment for fine classification in modern industries. Adaptable to various fine material processing scenarios, it remedies the technical shortcomings of traditional screening equipment in fine material treatment and meets the refined, efficient and large-scale production requirements of modern industries.
The equipment boasts core characteristics of high vibration frequency, low amplitude and strong screening permeability. Its vibration frequency reaches up to 3,000 times per minute (50Hz) with an amplitude of only 1-2mm, and the vibration intensity is 8-10 times the gravitational acceleration, 2-3 times that of ordinary screening machines. Adopting an innovative structural design with vibrating screen mesh and static screen frame, it generates extremely small dynamic load and requires no special equipment foundation, enabling flexible layout and convenient installation according to production line demands. Equipped with independently adjustable electromagnetic vibrators, each unit has a power of only 0.35kW, with far lower energy consumption than traditional mechanical screening equipment. The matched stainless steel composite screen mesh features excellent self-cleaning performance, effectively preventing material adhesion and screen blocking. It is easy to disassemble and replace, and can adapt to the screening of various difficult-to-treat materials with high humidity, high viscosity and fine powder properties.
Driven by high-frequency vibration generated by electromagnetic induction, the high-frequency electromagnetic vibrating screen has a simple structure without complex mechanical transmission parts, ensuring efficient and stable operation. It is mainly composed of electromagnetic vibrators, special screen mesh, fixed screen frame, shock-absorbing rubber springs and an intelligent electric control system. After power-on operation, the electromagnetic vibrator generates stable periodic electromagnetic force, which drives the vibrating rods and arms to perform high-frequency and micro-amplitude reciprocating motion through rubber springs, thus driving the screen mesh to vibrate at high frequency while the screen frame remains static throughout the operation. During production, materials are evenly spread on the screen surface from the feeding end. The high-frequency vibration breaks the surface tension between material particles, enabling fine particles to penetrate the screen quickly for classification, while coarse particles slide down along the screen surface for discharge, realizing accurate material classification, dewatering and desliming. The electric control system can independently adjust the parameters of each vibrator to flexibly adapt to the screening demands of different materials and processes.
Compared with traditional vibrating screens and spiral classifiers, the high-frequency electromagnetic vibrating screen has prominent comprehensive advantages. It delivers excellent screening performance with a classification accuracy of over 90%, which effectively reduces the circulating load of production, increases the processing capacity of grinding mills by 5%-20% and greatly improves production efficiency. Adopting pure electromagnetic drive without rotating or wearing parts, it requires no regular lubrication and maintenance, saving more than 30% energy compared with traditional mechanical screens and greatly reducing long-term operating costs. In addition, the equipment features stable operation, low failure rate and operating noise controlled within 70-73dB(A), complying with industrial green environmental protection standards. It has strong adaptability and can be customized into single-layer or multi-layer structures for both dry and wet screening, meeting the fine screening requirements of iron ore, quartz sand, coal slime, chemical powder and various other materials. Furthermore, the equipment is easy to maintain; the screen mesh can be replaced without professional tools or complex procedures, and daily maintenance only requires routine inspection of core components such as vibrators and springs, effectively reducing enterprise labor and maintenance costs.
Linqu Sanxing Electromagnetic Equipment Co., Ltd. has years of in-depth experience in the R&D, production and manufacturing of magnetic and electric screening equipment, with profound technical accumulation and mature production technology. Its high-frequency electromagnetic vibrating screens with stable performance and high screening efficiency serve hundreds of industrial and mining enterprises nationwide, covering mainstream industries such as mining, coal, metallurgy and building materials. A large iron ore enterprise in Shandong Province previously adopted traditional spiral classification equipment, which suffered from long-term problems including low classification efficiency, unstable concentrate grade, high energy consumption and frequent material blockages, seriously restricting production capacity and product quality improvement.
In 2024, the enterprise purchased a double-layer high-frequency electromagnetic vibrating screen from Linqu Sanxing Electromagnetic for the core fine classification operation of iron concentrate. After commissioning, the equipment realized accurate classification of -200 mesh particles, raising the screening efficiency from 65% to 92%, stably increasing the concentrate grade by 1.5 percentage points and improving the hourly output of the grinding mill by 12%. It saves more than 800,000 yuan annually in comprehensive costs including electricity and maintenance fees. In addition, numerous clients including large coal washing plants in Shanxi and quartz sand deep processing enterprises in Jiangsu have solved industrial pain points such as coal slime dewatering, accurate fine sand classification and material purification by adopting Sanxing's high-frequency electromagnetic vibrating screens. The equipment operates stably in long-term continuous production and has won wide market recognition for its high cost performance and stability, maintaining a high customer repurchase rate in the industry.
