Iron ore Ceramic Vacuum Disc Filter High Speed for Mineral Dewatering

?

?

Summary

?

The Disc Vacuum Filter is mainly used to deal materials like iron ore in metallurgical mineral processing. ZPG disc-type vacuum filter is using vacuum filtration as a driving force. And it has been driven by adjustable speed motor through speed reducer and exposed gear ,making it in the filled full pulp tank to rotate in a some speed. It is been widely used in iron ore, non-ferrous metals and non-metallic ore concentrate and tailings dewatering filter.

?

Features:

?

The disc vacuum filter fully draw on the advantages of similar foreign products, due to the features of large metal mineral density, fast settlement, solid particles in filtrate strongly shock the filter tube, we carried out an overall performance and reliable optimized design, with a feature of solid structure, filter plate smooth operation, automatic transmission with vigorous stirring, reliable shaft seal, ceramic filter tube wear long time with high filter fan strength, porosity, high strength filter cloth with smooth surface, high rate of cake discharge and long lifetime. All of these features for ZPG disk vacuum filter ensure that the metallic minerals good indicator of dehydration in solid-liquid separation.

Working principle

?

The basic steps in the operation of a vacuum disc filter are:

?

Cake Formation - An internal valve opens. This allows vacuum to be applied to the underside of the filter screen. The cake starts to form on the part of the drum that is submerged.

?

Cake Drying - As the drum rotates out of the slurry, the drying portion of the cycle begins. Vacuum continues to be applied in order to create the pressure differential necessary to remove the filtrate.

?

Cake Discharge - An internal valve is used to close off the vacuum at this point. The discharge mechanism can be either a scraper, belt, roll or string. Compressed air can be used to help remove the cake from the filter screen.

Advantages

?

High degree of automation, working with continues feeding, filtering, ore discharge, cloth washing. Large output and 24hrs continuous operation.

?

No secondary pollution.

?

The structure is compact, sturdy and durable. its key parts using the boron cast iron, wear-resistant ceramic composite pipe and other materials. It usually covers small area, and easy to install and operate and a wide range of usage.

?

Filter plate operate smoothly. fan filter made of high strength plastic, and have large porosity.

?

Excellent stirring effect, unique and reliable flexible shaft seal

?

Smooth Filter cloth surface, high cake discharge rate and difficult of clogging, long lifetime working.

?

With automatic centralized lubrication, cleaning device.

?

Low cake moisture, high filtration coefficient.

?

The machine has long lifetime. Low maintenance charge .
