Product Description

GYW Tubular Vacuum Permanent Magnet Filter

The GYW cylindrical vacuum permanent magnet filter is a solid-liquid separation device specifically designed for strongly magnetic minerals (such as magnetite). Its core feature is that it integrates a top feeding method and an internal permanent magnet system with traditional vacuum filtration, thus enabling efficient processing of coarse-grained slurries.
Core advantages
Extremely High Efficiency: Due to the thick and breathable filter cake, the dewatering efficiency is very high. Data shows that its production efficiency can be more than three times higher than that of a conventional cylindrical vacuum filter of the same specifications.
Highly Targeted: Specifically designed for strongly magnetic minerals with a relatively coarse particle size (0.15-0.8mm) and a specific magnetic susceptibility of not less than 3000 × 10^-6 cm³/g, typically requiring a feed concentration of over 60%.
Low Filter Cake Moisture: The moisture content of the final product can be controlled at a low level, typically 8-11%.

Main Structure

A typical cylindrical vacuum filter mainly consists of the following parts:

Cylinder: The rotating main body, its surface divided into multiple independent filter chambers.

Filter Cloth and Fixing Mechanism: The filter media wrapped around the cylinder, fixed to the cylinder with rubber strips, steel wire, or ropes.

Distribution Head: One of the core components, fixed at one end of the cylinder, internally divided into multiple zones, each connected to the vacuum and compressed air systems, controlling the cylinder's suction filtration, dewatering, and discharge at different positions.

Feed Tank and Agitator: Contains the slurry to be filtered; the agitator prevents solid particles from settling.

Drive Mechanism: Drives the cylinder to rotate at a certain speed.

Discharge Device: Such as a scraper, used to scrape the filter cake off the cylinder.

Working Principle Diagram

Working principle

1. Rapid Cake Formation: After the slurry is fed in from the top, the strontium ferrite permanent magnet system inside the cylinder generates a strong magnetic force. Under the combined action of magnetic force and their own gravity, the magnetic particles are rapidly adsorbed onto the filter cloth surface like "magnetic clusters," forming a filter cake. This adsorption process is highly efficient, unlike ordinary filters that rely entirely on vacuum suction.

2. Stratification and Dewatering: Top feeding allows coarse particles to settle and contact the filter cloth first, while fine particles form the upper layer. This stratified structure makes the filter cake thick and highly permeable. As the cylinder rotates into the dewatering zone, a vacuum pump removes the moisture from the filter cake.

3. Unloading and Washing: The dewatered filter cake is blown off by compressed air in the unloading zone. Afterward, the filter cloth enters the washing zone, where it is alternately rinsed with air and water to prevent clogging and ensure effective filtration in the next pass.
