Larox Filter Cloth

PRIMARY USES

1. Critical Filtration Media for Vertical Pressure Filters

Primary Use: Filter cloths are the essential filtration medium used in Larox® PF (Pressure Filter) series filters. They line the filter plates, forming the chambers where solids are captured while liquid filtrate passes through. They are crucial for mining, mineral processing, metallurgical, chemical, and industrial applications requiring efficient solid-liquid separation, dewatering, and cake washing.

How it helps: For process engineers and plant operators, the correct filter cloth selection is critical for the performance and reliability of the entire filtration process. OEM filter cloths are perfectly engineered according to strict standards for guaranteed reliability, offering optimized throughput and filtrate clarity. They are designed to provide excellent cake release and resistance to blinding, with stretch, shrink, and higher abrasion resistance for extended life and higher filter availability.

SECONDARY USES

1. Mining and Mineral Processing: Used for dewatering concentrates and tailings in copper, nickel, iron, lead, zinc, and lithium production.

2. Metallurgical Refineries: Essential for alumina, phosphate fertilizer, acid leaching extraction, and catalyst industries .

3. Chemical and Industrial Applications: Suitable for demanding processes requiring chemical resistance and high-temperature tolerance .

4. Food and Pharmaceutical: Used in starch production and bio-pharmaceutical applications .

5. Continuous Filter Belt Operation: The filter cloth functions as both a filtering medium and a conveyor belt, transporting solids cake (up to 20,000 kg) during discharge phases .

SAFETY HANDLING PRECAUTIONS

1. SAFETY PRECAUTIONS

Personal Protective Equipment (PPE): Always wear appropriate PPE, including safety goggles, gloves, and protective clothing when handling filter cloths.

Lockout/Tagout: Always isolate and lock out the filter press from its hydraulic and electrical power sources before beginning any maintenance or installation work.

Chemical Safety: Filter cloth material must be matched to the specific chemical composition of the process slurry to prevent chemical degradation or failure. Polypropylene is suitable for most chemical applications .

Training requirement: Maintenance personnel must be properly trained on the safe and correct procedures for handling and installing filter cloths on the specific Larox filter press model.

2. FIRST AID MEASURES

Eye Exposure: If slurry or chemicals splash into the eyes, flush immediately with plenty of clean water for at least 15 minutes, holding eyelids open. Seek medical attention.

Skin Contact: Remove contaminated clothing. Wash exposed skin with soap and water. If irritation develops or chemical burns occur, seek medical attention.
