Key Benefits for Continuous Filtration Projects
Use this product when a project needs stable continuous operation, configurable washing stages, and process-based equipment selection.
Continuous Automatic Operation
Reduce manual work and downtime through continuous feeding, filtration, washing, discharge, and cloth cleaning.
Large Processing Capacity
Filtration area, belt width, and running speed can be configured for large-scale industrial production.
Efficient Solid-Liquid Separation
Vacuum pressure helps separate filtrate from solids and supports moisture reduction after filtration.
Multi-stage Cake Washing
Single-stage, double-stage, or multi-stage washing systems can be selected to improve purity or recover valuable liquid.
PLC Automatic Control
Support start-stop control, belt speed adjustment, vacuum monitoring, operation display, and alarm management.
Customized Engineering Design
Hexin recommends filtration area, material selection, washing system, and automation scope based on project conditions.
Applications in Industrial Slurry Treatment
Horizontal Vacuum Filter is used where continuous solid-liquid separation, cake washing, moisture reduction, and filtrate recovery are required.
Mining & Mineral Processing
For iron, copper, gold, lead-zinc concentrate filtration, tailings dewatering, and process water recovery.
Discuss Application →Chemical Industry
For phosphoric acid filtration, titanium dioxide slurry, calcium carbonate, and industrial salt applications.
Discuss Application →Fertilizer Industry
For phosphate fertilizer, potassium fertilizer, compound fertilizer, and phosphogypsum filtration.
Discuss Application →Environmental Protection
For wastewater sludge dewatering, industrial residue treatment, moisture reduction, and resource recovery.
Discuss Application →Working Principle
The machine uses vacuum pressure as the filtration driving force. Slurry is evenly distributed on the moving filter cloth, liquid passes through the filter media into the vacuum chamber, and solids remain on the cloth surface to form filter cake.
Slurry Feeding
Slurry is distributed evenly onto the moving filter cloth.
Vacuum Filtration
Negative pressure draws liquid through the filter cloth into the vacuum chamber.
Cake Washing
Single or multiple washing stages remove soluble impurities when required.
Cake Drying
Continuous vacuum suction further reduces filter cake moisture.
Automatic Discharge
The filter cake separates from the filter cloth and is discharged continuously.
Filter Cloth Cleaning
The cloth is washed and regenerated before returning to the filtration cycle.
Main Structure and Components
The machine adopts a modular structural design. Multiple systems work together to maintain stable continuous filtration, washing, drying, and discharge.
Filter Belt System
Supports filter cloth movement, cake formation, belt tracking, and speed adjustment.
Vacuum Filtration System
Includes vacuum chamber, pipelines, vacuum pump, receiver, and separator.
Drive and Support System
Controls belt movement and supports long-term continuous operation.
Automatic Control System
Supports operation monitoring, belt speed adjustment, alarm indication, and process control.
Slurry Feeding System
Distributes slurry uniformly to maintain consistent cake thickness and improve filtration efficiency.
Cake Washing System
Supports single-stage, double-stage, or multi-stage counter-current washing according to process needs.
Cake Discharge System
Automatically separates and removes filter cake from the filter cloth for continuous production.
Filter Cloth Cleaning
Spray or high-pressure washing helps restore filtration performance and extend cloth service life.
Technical Specifications
Hexin Horizontal Vacuum Filters are available in different filtration areas. The final model should be selected according to material characteristics and project requirements.
| Model Reference | Filtration Area | Typical Selection Basis |
|---|---|---|
| BF-5 | 5 m² | Small-scale slurry filtration and pilot production |
| BF-10 | 10 m² | Small to medium continuous filtration lines |
| BF-20 | 20 m² | Medium-capacity mineral or chemical filtration |
| BF-30 | 30 m² | Continuous production with higher throughput |
| BF-40 | 40 m² | Large industrial slurry filtration applications |
| BF-60 | 60 m² | Large-scale mining, chemical, or fertilizer projects |
| BF-100 | 100 m² | High-capacity continuous filtration systems |
Final model selection depends on material characteristics, feed solids concentration, filtration speed, cake thickness, moisture target, washing requirement, installation conditions, and automation scope.
