The screen is a high frequency, high vibration strength for the main features of the vibration sieve, mainly for wet classification of solid-liquid separation of fine material below 0.5mm. In the coal preparation industry, its investment and operating costs low, making the most of the coal preparation plant has the ability to use their recycling slime in order to achieve a closed recycling of wash water and to improve the coal preparation plant environment, and the obvious economic and social benefits. At home and abroad has been widely promoted and applied.Research a foreign high-frequency shaker Back in the early 1950s, foreign R & D had a high frequency vibration sieve. In the metallurgical industry, as a concentrator fine iron ore grading; coal processing for slime dehydration, referral and classification. At present, foreign countries have the technology in the United States, Australia, Germany, France and Finland. Its products are also showing diversification, Schechita SLV type high-frequency vibration sieve dehydration,the Nord berg HF high frequency vibrating screen.From the accessible literature, the foreign high-frequency vibration sieve vibration parameters are a big difference, together, the vibration frequency 24 ~ 60Hz, the vibration strength is 5 ~ 11gn. Foreign production of high-frequency shaker has a handling capacity of large, high efficiency, stable performance, longer life expectancy, etc., but the disadvantages are expensive, a small amount of processing, cost is no thigher, at present, its largest span of only 1.8m. Although the foreign high-frequency shaker different models, but the principle is basically similar. One of the most typical American Derrick high frequency, the following screen, Weier Ke Dewatering Screen and SD-type high-frequency vibration sieve to be a brief analysis. In fact, the class of high-end laptops, such as digital SLR cameras million consumer network marketing has been very mature, second-hand cars online trading...
