In the field of mineral processing, vibrating screens, as the key sorting equipment, have developed technical branches that adapt to different working conditions.The high-efficiency heavy-duty screen adopts the principle of eccentric shaft excitation, with a processing capacity of up to 500 tons/hour. Its manganese steel screen can withstand the severe impact of ore, especially suitable for coarse screening of iron ore, copper ore and other metal mines.Through a unique self-centering mechanism, the self-centering vibrating screen can maintain stable operation at a speed of 980RPM. Its polyurethane screen can effectively reduce noise to less than 75 decibels, making it the first choice for fine-grained screening in coal preparation plants.
The elliptical vibrating screen combines the technical advantages of circular vibration and linear vibration to form an elliptical trajectory with an amplitude of 8-10mm through a three-axis drive, which increases the screening rate of quartz sand and other materials to more than 92%.The banana screen adopts a multi-stage inclination design (12°-25° gradient) and cooperates with the square steel screen structure to achieve a processing efficiency of 300 tons/hour in the sand and gravel aggregate production line.The dewatering screen relies on the combination of high-frequency vibration (1460 times/min) and stainless steel screen to control the moisture content of the concentrate within 15%.
The linear vibrating screen realizes rapid stratification of materials at a projectile angle of 30-50°, and its modular screen box structure supports 8 hours to complete the screen replacement, which is widely used in the fields of non-metallic minerals such as phosphate ore and potash.The swing screen is manually sieved through three-dimensional elliptical motion simulation, maintaining a 98% integrity rate for fragile materials such as graphite, but the processing capacity is only 60% of that of the traditional vibrating screen.Together, these equipment constitute the technical matrix for efficient grading of modern mines.
