Iron ore belt vacuum filter machine

Iron ore belt vacuum filter machineIt is a continuous solid-liquid separation equipment designed specifically for dewatering iron ore concentrates. It is driven by vacuum negative pressure and achieves efficient separation through the synergistic effect of an annular rubber filter belt and filter cloth. Its core structure includes high-strength rubber filter belt, vacuum sealing system, multi-stage fabric device, filter cloth regeneration unit, and intelligent control system. The filter belt is made of composite rubber material that is resistant to tension and corrosion, and its surface has been specially treated to enhance friction and wear resistance; The filter cloth is made of synthetic fibers or metal wire mesh according to the characteristics of iron ore, ensuring efficient interception of fine particles. The overall layout of the equipment is compact, supporting horizontal or slightly inclined installation, and adapting to different working conditions.

Iron ore belt vacuum filter machineworking principle

Fabric stage: The material is evenly spread on the filter cloth by the fabric spreader and moves synchronously with the rubber belt.

Vacuum filtration: The vacuum box creates negative pressure, liquid passes through the filter cloth into the vacuum system, and solid particles form a filter cake.

Washing stage: The filter cake undergoes multi-stage washing during its movement, and impurities are discharged with the washing solution to improve the purity of the filter cake.

Drying stage: further remove the moisture from the filter cake through vacuum suction to reduce the moisture content.

Unloading and regeneration: After the filter cake is peeled off by a scraper, the filter cloth enters the cleaning area for regeneration, completing one cycle.

Application field

Iron ore selection and purification: used for dewatering concentrates such as magnetite, hematite, and limonite to improve product grade and meet smelting raw material standards.

Tailings resource recovery: Secondary dewatering of beneficiation tailings to recover residual iron elements and improve resource utilization.

Steel industry assistance: In the production of sintered ore and pellet ore, pre dehydration treatment of raw materials is carried out to reduce energy consumption and production costs.

Environmental engineering: Treating suspended solids in steel plant wastewater, reducing pollutant emissions, and complying with environmental regulations.

Chemical co production application: Combining with chemical processes to recover associated elements (such as cobalt and nickel) from iron ore, achieving comprehensive utilization.

installation and debugging

1. The overall modular design allows for flexible assembly, making it easy to transport and install.

2. High degree of automation; Cutting, filtering, washing, drying, unloading, and cleaning of filter cloth are all continuously automated, which improves production efficiency, reduces operating costs, greatly reduces labor intensity for workers, and improves the working environment.

3: Fast filtering speed; The material passes through the sedimentation zone, with large particles in the bottom layer and small particles in the upper layer. The filter cake structure is reasonable, and the filtrate has low permeability resistance, allowing for rapid thin-layer filtration.

4: Convenient filtration process; Filter cake thickness and washing water volume. The reverse washing stage, vacuum degree, and filter cloth speed can be adjusted arbitrarily to achieve better filtration effect.

5: Good washing effect; It can achieve multi-stage parallel or countercurrent washing, with uniform washing. The mother liquor and washing solution can be collected and reused separately according to process requirements.

6. The control system applies DCS technology, which can achieve on-site and remote automatic control.
