Polyurethane High frequency screen has the advantages of high screening efficiency, large processing capacity, compact and reasonable structure, small footprint, and low power consumption.
The screen frame is supported by a rubber spring suspension, with low noise, low power consumption, and small equipment dynamic load, so there is no special requirement for the installation foundation.
Forcing the pulp to be distributed to the mine, the pulp can be spread evenly on the screen surface, reducing the slurry flow rate on the screen surface, and extending the life of the screen.
Dual vibrator configuration, linear vibration and patented technology of re-pulping, the screening material has a long flow area, fast transmission speed, and has a greater screening capacity and screening effect. The surface of the equipment is treated with anti-corrosion and wear-resistant spray glue, which effectively extends the life of the equipment.
Technical parameters of high-frequency vibrating screen: mainly refers to the amplitude, vibration intensity, mesh size and feed concentration. Process parameters: mainly refer to the moisture on the sieve, the moisture on the sieve and the dehydration efficiency. Technology and process parameters are closely related, and many scholars have done related research.
The influence of vibration intensity on the screening process index is greater than the influence of the working frequency on the screening process index. When the feed concentration is 45%-60%, the sieve machine has a higher recovery rate. The size of the sieve hole is 5 mm, which has a great influence on the humidity and relative humidity of the material, the sieve and the relative humidity of the water and dehydration effectiveness. Sun Yechang et al. established a mathematical model between the output of the vibrating screen under the high-frequency vibrating screen and the ore concentration, feed composition and processing capacity.
It is found that the optimal concentration is 30.50%, and the change of the concentration between 25% and 35% has almost no effect on the yield under the sieve, but the reduction in the yield under the sieve increases the treatment amount, and the linear relationship is linear with the increase of 74 mm particle content .
