The ZPG Series vacuum disc filter has the common advantages of low cake moisture, high filter coefficient, small occupied area, lower energy consumption and so on, at the same time, through practical application shows that the product technology and performance indicators have reached the advanced level of domestic similar products. Aimed at metal mineral high density, fast sedimentation, and the strong impact strength to the filtrate tube causing by filtrate, containing solid particles; conduct optimized design between the overall performance and comparability between the various components, ensure the metallic minerals in the solid-liquid separation to obtain a good indicator of dehydration. Now proved by practice, the product technology and performance have met or exceeded the international advanced level of similar products.

When working, the filter disc circles in the slurry tank. With the help of pressure difference generated by vacuum pump, the particle is absorbed on the cloth of the disc and forming a filter cake with a certain thickness. Filtrate will discharge from the central shaft through the filter cake and cloth, and the filter cake will fall down under the pressure of the scraper and blower, and then drop into the discharging filter cake tank.
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 produce good sealing effects.
5. The filtrate pipes are high-strength and abrasion-resistant ceramic lined steel pipes whose service 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 substantially.
7. Continuously variable transmission is adjusted according to the concentration and flow of materials (adjustable speed motors with alternating current or frequency converter) to achieve ideal working effects.
8. The oil pump is lubricated automatically at many points to ensure normal operation of equipment.
This machine is specially designed used for dehydration in iron ore concentrate, silver mine and non-ferrous metal concentrate, also suitable for coal washing, nonmetallic mine, chemical industry, environmental protection and so on.
