Research Level Introduction to Foreign Vibrating Screen
In general linear vibrating screen is rest on horizontal ground and the vibration direction angle is 45°, under this circumstance the performance parameters of sieve machines are justice configuration, the machine will have high operation speed, high capacity and high screening efficiency. However the linear vibrating screen can also be placed on an angle, usually 5°or 10°according to the requirements of individual process and the special needs. Linear vibrating screen is mainly used for fine material grading and dehydration dehxjq. So the too large angle may result in poor screen efficiency.
Vibrating screen is mainly characterized by a high frequency, high vibration strength, and is mainly applied to the wet classification of 0.5mm or less fine material and solid-liquid separation. In the coal dressing industry, it was used to recover slurry in the most coal dressing plant for its low investment and operation costs. It has been widely promoted and applied at home and abroad.
The vibrating screen had been researched in the abroad in the early 1950s. In the metallurgical industry, it was used for classifying fine iron ore in the ore beneficiation plant. In the coal processing industry, it was used for slim dehydration, referrals and classification. At present there are many countries with this technology, such as the United States, Australia, German, France and Finland. The product also has many types, such as SLV type high frequency vibrating screen produced by Schenck Company and HF type vibrating screen by Nordberg Company. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like cement production line, Henan Hongxing is always doing the best in products and service.ore elevator machine: http://www.hxjqchina.com/n99.html
From the published literatures, the vibrating parameters of foreign-designed high-frequency vibrating screen are very different. Taken together, the vibration frequency is 24-60 Hz, the vibration strength is 5-11gn. Foreign high-frequency vibrating screen has large handling capacity, high efficiency, stable performance, longer life, etc., but the main drawback is expensive and low cost performance. Its largest span is only 1.8m. Although the foreign high-frequency vibrating screen models are very different, the basic working principle is similar.
Henan Hongxing Mining Machinery Co., Ltd has many years” of technological power and experience accumulation of manufacturing and management of hammer crusher machine, mining spirals which have many advantages such as simple and reasonable structure, high independent impact crushing ability, super low operational cost and the most competitive price. These machines have the most competitive price and the most reliable quality so that they are the top choice for the high performance crushing equipment.
