(Summary description)The filtration equipment commonly used in concentrators is vacuum filter. There are three types of vacuum filters: cylindrical filters (internal filter type, external filter type, folded belt type, permanent magnet external filter type, etc.), disc filters and flat filters (turntable type, belt type, etc.).

The filtration equipment commonly used in concentrators is vacuum filter. There are three types of vacuum filters: cylindrical filters (internal filter type, external filter type, folded belt type, permanent magnet external filter type, etc.), disc filters and flat filters (turntable type, belt type, etc.). The filter press has intermittent operation, continuous operation filter press and belt filter press.
The cylindrical inner filter vacuum filter is suitable for processing materials with coarse particle size (but not too coarse, -0.074mm should be greater than 50%), high density and fast settling speed. Often used for iron ore concentrate filtration.
The cylindrical external filter vacuum filter and the folding belt filter are suitable for processing materials with fine particle size, low sedimentation speed, and low moisture content of the filter cake. The latter is more adaptable to fine viscous materials, and its filter cake moisture is lower than that of ordinary external filter filters.
The cylindrical external filter permanent magnet filter is a high-efficiency filter specially used for filtering coarse magnetite concentrate. The processing capacity per unit area is very high, and it can reach 3t/(m2•h) when the concentrate particle size is 0.8~0mm. The moisture content of the filter cake is slightly higher than that of the general cylindrical filter.
The disc filter has a large filtering area and a small footprint, and is suitable for processing materials with fine particle size and low sedimentation speed. The moisture content of the filter cake is slightly higher than that of the cylindrical external filter. Disc filters are widely used in foreign ferrous and non-ferrous metal concentrators, coal preparation plants, etc. At present, they are mostly used in non-ferrous metal concentrators and coal preparation plants in China. Rotary disc and belt filters are suitable for processing materials with coarse particle size, high density and high feed concentration.
The filter press is suitable for processing fine and viscous materials that are difficult to handle by vacuum filters.
