01
Equipment development:
 
Since the world's first dense medium cyclone (D.M.S) came out in 1945, it has been widely used for its small volume, large processing capacity and high separation efficiency; China's dense medium cyclone has been self-designed and applied since the 1960s, and has been developing continuously through a series of reforms and innovations during this period, batch by batch of different types of dense medium hydrocyclones with novel structure have been presented It has been applied and popularized in production.
 
02
Technical features:
 
Weihai Haiwang hydrocyclone Co., Ltd., as the earliest professional manufacturer of hydrocyclone in China, has been committed to the development and promotion of dense medium cyclone separation technology for more than 30 years. At present, the two products of Haiwang hydrocyclones are mainly FZJ series, covering Φ 150 ~ Φ 1500mm, with more than 20 specifications and models, which are widely used in heavy medium separation of lump coal, fine coal and slime in coal preparation industry In art.
In recent years, in response to the large-scale development of process equipment in coal preparation plant, our company has developed Φ 1550, Φ 1600 super large two product heavy medium cyclone, and has been successfully applied in the field, which has made an important contribution to simplify the process flow of coal preparation plant and reduce the investment cost.
FZJ series two Product Dense Medium Cyclone adopts centrifugal volute type patented structure feed body design, optimizes column diameter ratio, and checks cone ratio configuration according to coal quality characteristics. Compared with the traditional structure, the processing capacity is increased by 30-50%, and the separation efficiency is increased to more than 98%. Haiwang heavy medium cyclone with large diameter has passed the national appraisal and reached the international advanced level.
03
Typical applications:
 
Haiwang company undertakes the research project of high-efficiency cyclone separation technology of dense medium cyclone in a coal preparation plant of national energy. The same model fzj1450 replaces the original Australian imported dense medium cyclone, which solves the problem of large loss of clean coal caused by intermittent discharge of gangue.
 
Field application
After the successful implementation of the project, optimize the existing production indicators, stabilize the quality of clean coal products, reduce the loss of clean coal, ensure that the ash content of dense medium clean coal is 5%, and the processing capacity can reach 800 t / h after desliming (Φ 1.5 mm desliming); at the same time, the production rate of dense medium clean coal in the coal preparation plant is increased by 2.37%, which is calculated by 300 days and 14 hours a day throughout the year More than 6 million yuan of new economic benefits.
