Mineral Separation Equipment

Drum Filter

Drum Filter is slurry dewatering equipment produced by DMTC Mining, a Chinese manufacturer of mining and mineral processing equipment based in Dalian, exporting to 100+ countries.

The inner type filters are suitable for coarse particle, big density with quick settlement materials treatment, mainly used for processing magnetic separating or floating iron ore concentrate, with such features as easy forming filter cake, good permeability of filter cake, not easy for jamming of filter cloth.
The external type and fold belt type filters are mainly used for fine granularity, slow sedimentation rate and low requirement to moisture materials as non-ferrous metal and non-metal ore concentrate filtering works, magnetic external filters are suitable for coarse particle magnetic iron concentrate with significant effect and reach capacity of 3t/m²·h, the features of such filters are obvious layer as particle with good air permeability, high production efficiency, and less water volume passed through filtering chamber.
The GYW series covers seven models from GYW-3 to GYW-30, with filter area of 3 to 30 m² and production capacity of 6 to 150 t/h.

Note 1: In the catalogue, Rotational Speed, Required Vacuum, Air Extraction Rate, Blowing Pressure and Blowing Air Rate are merged cells: 0.5-2.0 r/min spans GYW-8 to GYW-20 (GYW-30 = 0.4-1.5), while the other four rows merge from GYW-8 to GYW-30, leaving GYW-3 and GYW-5 blank. Merged cells are reproduced here with colspan.

Note 2: Magnetic Induction Intensity on Drum Surface gives only two values: 82 mT for GYW-3 to GYW-8 and 87 mT for GYW-12 to GYW-30.

Note 3: Filter Cake Moisture gives only two values: 8-10% for GYW-3 to GYW-8 and 8-11% for GYW-12 to GYW-30. Feed Pulp Density is one merged value, ≥60%, over all seven models.

Note 4: Motor Power is merged in the catalogue: 1.5 kW over GYW-3 to GYW-8 and 4 kW over GYW-18 to GYW-20; it is expanded per column here.

Note 5: The row label for Required Vacuum is printed in the catalogue without a closing bracket; the unit of Motor Power is printed as "kw" in the row label and as kW in the heading. Both are reproduced as printed.

Applications

Dewatering of coarse-particle, high-density, fast-settling materials (inner type filters).
Filtration of magnetic-separation or flotation iron ore concentrate.
Filtration of fine-granularity, slow-settling materials with low moisture requirement, such as non-ferrous metal and non-metal ore concentrate; the magnetic external type suits coarse-particle magnetic iron concentrate.
