Product Details

Plate and Frame Filter Press

The Plate and Frame Filter Press is the most widely used solid-liquid separation equipment in mining. It uses mechanical pressure to force slurry through filter cloth, retaining solids as "filter cake" and discharging clear filtrate.

With a moisture content as low as 15-20%, it is essential for dry stacking of tailings and concentrate dewatering in Gold, Copper, and Coal washing plants.

Working Principle: Pressure Filtration

Intermittent operation cycle: Pressing - Filtering - Discharging.

01

Closing (Pressing)

The hydraulic cylinder pushes the moving head plate, compressing the pack of filter plates tightly to seal the chambers.

02

Feeding & Filtering

Slurry is pumped into the chambers. Liquid passes through the filter cloth and exits via drainage ports. Solids build up to form a cake.

03

Cake Discharge

Once the chamber is full, the feed pump stops. The plates are opened automatically or manually, and the dry cake falls out.

Hydraulic Filter Press Structure

Technical Choice: Recessed Chamber vs. Plate & Frame

Which plate type is right for your slurry?

Feature Recessed Chamber Filter Press Plate and Frame Filter Press
Structure Single plate type (Recessed). Two types (Flat plate + Hollow frame).
Pressure High (Up to 1.5-2.0 MPa). Medium (< 0.6 MPa).
Discharge Easy (Auto shifting possible). Harder (Cake may stick to frame).
Application Mining, Tailings, Heavy Sludge. Fine Chemical, Pharma, Clarification.

Core Advantages

1. Low Moisture Cake

High-pressure filtration (up to 1.5 MPa) produces a dry filter cake with low moisture content (15-20%), which is easy to transport and stack.

2. Clear Filtrate

The filter cloth intercepts even the finest particles (down to a few microns), producing clear filtrate that can be directly recycled to the plant.

3. Automated Operation

Features hydraulic compression, automatic pressure retention, and automatic plate shifting (optional), reducing labor intensity.

Typical Applications

  • ● Tailings Dry Stacking:
    Pressing tailings into dry cakes to prevent dam failure. See Tailings Solution.
  • ● Concentrate Dewatering:
    Reducing moisture of Copper, Iron, and Lead-Zinc concentrates for shipping.
  • ● Coal Slime:
    Recovering fine coal and clarifying water in Coal Preparation Plants.
  • ● Stone Wastewater:
    Treating sludge from marble/granite cutting and polishing.

Maintenance Guide

  • Filter Cloth: Clean monthly. Replace when damaged or heavily clogged (Life: 3-6 months).
  • Hydraulic Oil: Check level daily. Change every 3-6 months (Anti-wear hydraulic oil).
  • Filter Plates: Check sealing surfaces for damage. Replace warped plates to prevent spraying.

Frequently Asked Questions (FAQ)

Q: How do I select the right size?

A: You need to know your Daily Solid Volume (Tons) and Filter Cycle Time (usually 1-2 hours). We will calculate the total volume (Liters) required per cycle.

Q: Can it run automatically?

A: Yes. We offer fully automatic models with Auto-Plate Shifting, Auto-Cloth Washing, and PLC control. Manual models are cheaper but labor-intensive.

Q: What is the cake moisture?

A: It depends on the material. For mineral tailings, moisture is typically 15% - 20%. For sludge, it might be 25% - 40%. Using a membrane squeeze press can lower moisture further.
