oil filter in mineral processing industry of application
With the increasing impoverishment of mineral resources, in order to improve the comprehensive utilization rate of mining, it is necessary to grind the ore more finely, so as to improve the mineral processing index and product quality. The metallurgical industry requires high grade and low moisture content of raw materials before smelting or processing. Thus filtration and dehydration have become basic processes in both industries. Various industrial filters are playing an increasingly important role in the mineral processing, metallurgy and coal industries.
Concentrate is the final product of concentrator, and filtration is the essential operation of concentrate dehydration. In the past, vacuum filters were used to filter concentrates, such as rotary drum vacuum filter and disk vacuum filter, which still occupy a dominant position in some concentrators. The advantage of using vacuum filter to dehydrate coffin mine is that it can work continuously, it is easy to operate and has a large production capacity. This filter is a kind of more suitable and advanced equipment under normal conditions. However, for the thin and han concentrate filtration, will appear a series of problems, such as difficult filtration, filter cake moisture. Low output, transportation difficulties, high energy consumption, metal loss, environmental pollution, etc. Although the vacuum process has been constantly improved, the results are not satisfactory. Fine particle concentration worsen the traditional dehydration method effect, from the Angle of saving resources and protecting the environment, consider all need to modify traditional dehydration art c recently abroad using automatic pressure filter, ceramic disk vacuum filter and large horizontal belt vacuum filter and other new type of fine filter for filtering and rice ore has made remarkable progress, China is also actively promote the application and effective.
