Iron ore fines used vacuum disc filter, ZPG72-6 disc filter for sale

Iron ore fines used vacuum disc filter, ZPG72-6 disc filter for sale

Requirements for dehydrating objects of this rotary filter press are as follows: 

1.1 Mineral granularity is 100 to 400 meshes. 

1.2 Pulp density is 35%~65% (metallic mineral) or 20%~40% (coal and other lightweight materials). 

1.3 Pulp temperature is 10℃~30℃. 

1.4 Material is non-corrosive (when corrosive material is treated, it shall be specially designed). 

Vacuum disc filter uses vacuum as its filtering power to carry out solid-liquid separation of pulp.  

Unloading by anti-blowing, variable speed agitating, and automatic centralized lubrication and other advanced technologies make it to be the dehydration equipment with good performance and reliable application. 

This machine is the new type disk vacuum filter exclusively designed for the dehydration of iron ore concentrate and non-ferrous metal ore. It also applies to coal washing plant, as well as non-metal ores, chemical industry and environmental protection operation.

Technical characteristics of this vacuum disc filter:

1. Overcoming some defects in the use of existing filter fans, the new filter fans we designed are characterized by even distribution of dewatering holes, reasonable aperture ratio, high strength(the material of screen fans is high strength engineering plastic), long service life(the life increase 1 to 1.5 times on average) of it, as well as long service of filter cloth. Besides, the effective area of screen fans is large which improves the handing ability of filter.

2. The structure of filtrate pipe is optimally designed. Leakage due to aging of rubble at the joint of original flange is completely avoided.

3. The ends of agitating shafts adopt the flexible sealing method of three elements”rubber,permanent magnet, and water seal” initiated in China which effectively prevent leakage of slurry.

4. Specially made abrasion-resistant boron cast-iron friction plates are adopted which prduce good sealing effects.

5. The filtrate pipes are high-strength and abrasion-resistant ceramic lined steel pipes whose servise life is prolonged for over 5 times

6. Ten arc small press cakes are adopted for successive mutual gripping to press the screen fans within a plane. This helps the maintenance persons to have less work during the replacement of filter fans or filter cloth. Their labor intensity is reduced subtantially.

7. Continounsly variable transmission is adjusted according to the concentation and flow of materials(adjustable speed motors with alternating current or frequency converter) to achive ideal working effects

8. The dry oil pump is lubricated automatically at many points to ensure normal operation of equipment.

Working principle of vacuum disc filter.

Vacuum disc filter is solid-liquid separation equipment. Filter Disk is driven by motor through reducer and open gear transmission, and it can rotate with certain speed in the tank filled with pulp. In the adsorption area, pressure difference is formed at two sides of filter medium by vacuum pump, so solid material can be adsorbed on the filter media (filter cloth) and filter cake is then formed. When this part of filter disk is separated from pulp and enters into dehydration area, the water is continuously separated from the filter cake under the suction force of vacuum and is discharged from filtrate pipe and distributing head. Filter cake is dried in this way. After entering into the unloading area, filter cake is unloaded from filter disk by scraper (or anti-blow), falls into the material discharging channel and is taken away by gathering and belt conveyor. The whole operation process is carried out continuously.
