High Frequency Vibrating Screen introduction
High Frequency Vibrating Screen, simple structure,light weight to move and freely adjust height, The vibration frequency is high up to 3000 times per minute. High screening precision and efficiency, it applies to any powder,granule . In addition to electrical parts, the other parts are made of SUS304 or SUS316L.
Working principle
The high frequency Vibrating Sifter is a different working principle compared with ordinary screening device. Because of high frequency , it is able to destroy the tension on pulp surface, make small grain material vibrate at high speed on surface, able to accelerate to the separation of heavy organic minerals, increase the probability of material (smaller than separation degree) contact with screen hole. Thus this unique characteristic has created better separating condition that make the material (smaller than separation degree) pass the screen hole easily, especially the large proportion of grain and slurry, too.

Recently, the construction project of the river and lake dredging dredger undertaken by China Water Resources Investment Group Co., Ltd. (hereinafter referred to as Guoshuitou) was completed and accepted by the Ministry of Water Resources in Beijing.
The construction project of dredging dredgers for rivers and lakes undertaken by Guoshuitou is a key project for flood control determined by the Central Committee of the Communist Party of China on Several Issues Concerning Post-Disaster Reconstruction, Renovation of Rivers and Lakes, and Construction of Water Conservancy (Zhongfa [1998] No. 15). The former State Planning Commission, the Ministry of Water Resources, China International Engineering Consulting Corporation and the former China National Shipbuilding Corporation jointly established a dredger construction project leading group, and entrusted China Water Resources Investment Corporation as the responsible unit of the dredger construction project, responsible for project construction management. The total investment of the project is 686.3 million yuan, of which the central budget is 626.4 million yuan and the local supporting fund is 59.9 million yuan. The project is implemented by the government in a unified manner, and the design and manufacturer are selected by means of open tendering. Therefore, this project is one of the earliest projects to implement “government procurement†in China, and it is also the earliest implemented project of “agent construction system†in terms of operation mode.
Since November 1999, it has been completed and completed by the end of 2003. The project has built a total of 53 specifications of 53 dredgers and ancillary facilities, of which 35 dredgers were designed and built in China, and 18 were designed and imported from abroad. Built in the country. Since the above-mentioned dredgers have been put into use in May 2001, the dredging and dredging volume has been completed by 120 million cubic meters, which has played a good social and economic benefit.
In addition, Guoshui Investment strictly controls construction costs during project construction and reduces the cost of dredgers. The savings are about 70 million yuan.
The Completion Acceptance Committee established by the Ministry of Water Resources is represented by the relevant departments of the Ministry of Water Resources, the Yangtze River Committee, the Yellow Committee, the Huai Committee, the Haimen Committee, the Jiangxi, Hunan, Anhui, Guangdong, Liaoning, Heilongjiang, Hubei Province Water Resources Department and invited experts. 27 people.
Members of the Completion Acceptance Committee went to the Tangguhe Lake Dredging Dredger in Tianjin to check the operation of the dredger and the supporting facilities. After completing the "Report on Construction Management Work" and "Report on Operation Management of Dredgers" made by Guoshui Water Investment, the Completion Acceptance Committee passed the "Completion Acceptance Certificate" after discussion. The acceptance conclusion is that the rivers and lakes are dredged. The dredger construction project has been completed in accordance with the approved construction content and the quality is qualified. Project investment control is reasonable. Financial management and accounting are relatively standardized. The final financial statement has been audited. The archives basically meet the requirements of the regulations. The dredger is operating normally and has played a good social and economic benefit. The Completion Acceptance Committee agreed that the construction project of the dredging dredger in the river and lake will pass the completion acceptance.
