JKL-24 Pedestal-Type Laboratory Pressure Filter

1. General Description

The JKL-24 Pedestal-Type Laboratory Pressure Filter is a batch-operated metallurgical unit designed for solid-liquid separation of mineral slurries, concentrates, and tailings in laboratory testing, process control, and metallurgical research applications.

The unit features a 24-liter effective capacity and a 12-inch nominal diameter, allowing the processing of representative sample volumes for thickening tests, final moisture determination, filter cake characterization, and filter media performance evaluation.

Its robust pedestal-mounted structural design ensures operational stability, mechanical integrity, safe operation, and high repeatability of metallurgical results.

2. Main Applications

• Mineral concentrate filterability testing
• Determination of residual cake moisture
• Comparative evaluation of filter media
• Filtration pressure optimization testing
• Solid-liquid metallurgical balance studies
• Laboratory-scale simulation of industrial filtration conditions

3. Main Technical Specifications

4. Main Components

• Filtration cylinder fabricated in AISI 316 stainless steel (high resistance to corrosive environments).
• Perforated support plate for filter medium backing.
• High-precision worm-drive tightening mechanism ensuring uniform sealing pressure.
• Integrated safety valve and pressure relief system.
• Direct-reading pressure gauge for process monitoring.
• Quick pneumatic coupling for compressed air supply.
• Reinforced pedestal support frame with stabilizing base.

5. Operating Principle

1. Mineral slurry is charged into the filtration cylinder.
2. The selected filter medium (cloth or filter paper) is properly installed.
3. The cover is secured using the worm-screw tightening mechanism.
4. Controlled pneumatic pressure is applied.
5. The liquid phase passes through the filter medium.
6. Solids accumulate forming a consolidated filter cake.
7. The system is fully depressurized prior to opening.
8. The filter cake is removed for moisture determination and metallurgical analysis.

The mechanical interlocking design prevents opening under pressure, ensuring safe operational conditions.

6. Technical Advantages

• High chemical and mechanical resistance.
• Reliable pressure sealing performance.
• Certified operational safety via integrated pressure relief system.
