Product Overview
What Is a Mineral Washing and Filtration Production Line?
The ore washing, crushing, and filtering production line crushes and washes ore, and the wastewater after washing is filtered through a filter press. The filtered clean water is recycled.
It typically consists of:
- Vibrating Feeder
- Ore Washing Machine
- Jaw Crusher
- Sand Making Machine
- Filter Press
This production line is an essential process for ores with high mud content.
The ore washing, crushing, and filtering production line typically involves feeding mined ore or minerals to a jaw crusher for primary crushing via a vibrating feeder. The crushed material then enters a washing machine, where a high-pressure spray cleaning array washes away the attached mud before proceeding to the fine crushing or sand making process.
To meet environmental protection requirements and save costs, the wastewater from the washing process is collected in a wastewater tank and then filtered in a chamber filter press. The resulting clean water can be recycled, achieving clean and efficient production.
PRODUCTION PROCESS
Mineral Washing and Filtration Process
The ore washing, crushing, and filtering production line is an integrated mineral processing system encompassing:
- Feeding
- Primary Crushing
- Ore Washing and Desliming
- Fine Crushing / Sand Making
- Wastewater Treatment
- Water Recycling
It is primarily suitable for the pretreatment and deep processing of ores with high clay content and severe mud-coating, such as:
- Limestone
- Manganese Ore
- Iron Ore
- Bauxite
- Gold Ore
This process combines physical cleaning with mechanical crushing to improve the quality of finished aggregates while achieving closed-loop recycling of production wastewater, reaching the environmental goal of zero or near-zero emissions.
PLANT ADVANTAGES
Why Choose A Mineral Washing And Filtration Production Line?
Improve ore quality, increase recovery rates, and optimize downstream processing through efficient washing, desliming, and filtration technology.
Improved Ore Purity
Mineral washing removes clay, mud, dust, and surface impurities, resulting in cleaner ore and higher product quality.
Higher Recovery Rate
Effective desliming and classification reduce valuable mineral losses and improve overall processing efficiency.
Flexible Plant Configuration
The production line can be customized according to ore type, capacity requirements, water conditions, and project budgets.
MAIN EQUIPMENT
Main Equipment Configuration
A complete mineral washing and filtration production line consists of crushing, washing, screening, dewatering, and filtration equipment designed to improve ore quality and recovery efficiency.
Vibrating Feeder
Equipment
GZD / ZSW Series Vibrating Feeder.
Function and Principle
The vibrating feeder is installed below the storage silo. Two symmetrically arranged vibrating motors provide excitation force, driving the trough to reciprocate linearly along an inclined direction (usually 10°–15°).
When the vertical component of the vibration acceleration exceeds the acceleration due to gravity, the material is periodically thrown up and jumps forward along a parabolic trajectory, achieving continuous and uniform feeding.
Technical Highlights
- High manganese steel (Mn13) or wear-resistant alloy lining.
- Bar feeder can pre-screen materials smaller than 50 mm.
- Feed rate adjustable from 0–100%.
- Capacity range: 80–800 t/h.
Process Significance
Ensures uniform feeding of the jaw crusher and avoids overload conditions.
Jaw Crusher
Equipment
PE / PEX Series Jaw Crusher.
Function and Principle
The jaw crusher uses the periodic squeezing motion of the moving jaw plate relative to the fixed jaw plate to apply bending, squeezing, and splitting force to large ore pieces entering the crushing chamber.
Key Technical Features
- Feed size up to 1200 mm.
- Adjustable discharge size: 60–300 mm.
- Crushing ratio: 4–8.
- High manganese steel jaw plates.
- Deep cavity design.
- Hydraulic discharge adjustment.
Process Significance
Coarse crushing increases the specific surface area of ore and prepares material for efficient washing and desliming.
Ore Washing and Desliming
Equipment
- Rotary scrubber
- Spiral Washer
- Tank Washer
Function and Principle
After coarse crushing, ore surfaces and fissures are covered with mud, dust, and soluble impurities.
The washing machine combines:
- Mechanical agitation
- High-pressure water spray
to separate mud and impurities from ore.
Drum Washer Features
- Drum speed: 3–8 r/min.
- Multiple high-pressure spray pipes.
- Water pressure: 0.3–0.6 MPa.
- Screen opening: 10–20 mm.
Spiral Washer Features
Suitable for ores with:
- Particle size ≤150 mm
- High mud content
Provides more thorough cleaning but lower capacity.
Technical Highlights
- Water consumption: 1–3 m³/t ore.
- Spray pump head ≥40 m.
- Wear-resistant lining.
- Optional dual-stage washing system.
Process Significance
Removes clay coatings, improves crushing efficiency, improves product purity, and prevents blockage problems.
Fine Crushing and Sand Making
Equipment
- Cone Crusher
- Impact Crusher
- VSI Sand Maker
Recommended Applications
| Equipment | Best For | Discharge Size |
|---|---|---|
| Cone Crusher | Granite, Basalt, Iron Ore | 5–40 mm |
| Impact Crusher | Limestone, Coal Gangue | 5–30 mm |
| VSI Sand Maker | Manufactured Sand | 0–5 mm |
Technical Highlights
- Hydraulic cone crusher with overload protection.
- Impact crusher crushing ratio: 20–50.

- HRT ≥2–4 hours.
- Slurry concentration: 10–30%.
Chamber Filter Press
Equipment
XMY / XMZ Series Chamber Filter Press.
Working Principle
The slurry is pumped into a sealed filter chamber under pressure.
The liquid passes through filter cloth while solids remain and form a filter cake. As pressure increases, additional dewatering occurs.
Technical Highlights
- Reinforced PP filter plates.
