The application of high pressure automatic filter press in alumina production

2016-06-03

Bauxite is the raw material of producing alumina, refractory material and building material. In the process of produce alumina from Bauxite, it needs to adopt Separation filtration technology. Among it, filtering water from aluminum hydroxide suspension is the key process.

The traditional splitter is rotary drum vacuum filter press, but because of the filter cake is too big, then, it was replaced by the high pressure automatic filter press gradually. In 1980s, high pressure automatic filter press was introduced to our country, from then, the process of producing aluminum hydroxide has taken on an entirely new look.

Compared with rotary drum vacuum filter press, high pressure automatic filter press has the following advantages: water-saving, steam-saving and gas-saving. Because the cake residual moisture can be reduced greatly by the high pressure automatic filter press, the capacity of aluminum hydroxide would be improved greatly.
