Larox Filter Plate

PRIMARY USES

1. High-Performance Filtration in Mining and Industrial Processes

Primary Use: Filter plates are the core components of Larox® automatic pressure filters, used for solid-liquid separation in mining, mineral processing, and industrial applications. Essential for dewatering concentrates, tailings, and other process slurries to recover valuable solids and produce clean water.

How it helps: For process engineers and plant operators, Larox filter plates are designed for long life and corrosion resistance, with each chamber having its own filtration area on both sides for maximum efficiency. Polypropylene filter plates are available for Larox PF 1.6, 12, and 15 filters, while steel plates are also offered for demanding applications. Metso’s plastic filter plates are engineered for unmatched reliability in corrosive environments, with a one-piece plate body supported by a stainless steel frame for lightweight durability and corrosion resistance.

2. Advanced Technologies for Durability and Performance

Primary Use: Larox filter plates feature specialised sealing components, diaphragms, and vats that work together for optimal filtration performance.

How it helps: Sealing flats are filter plate components that ensure the perfect sealing of the filter chamber, manufactured from high-quality materials able to withstand compression for tens of thousands of cycles while retaining their shape. The pressing diaphragm compresses the cake through diaphragm pressing, transforming the force of pressing air or water into mechanical pressing while protecting the plate against corrosion and forming a sealing frame. The filter vats are engineered for wear and creeping resistance with plastic material selection optimised for molecular weight and polymer properties to prolong lifetime in demanding mining applications.

SECONDARY USES

1. High-Temperature and Chemical Applications: Plastic plates are the ideal choice for small and mid-size PF filters in industrial applications with highly corrosive chemical composition of slurries, with a temperature range up to 90°C and FDA & Chemi range for industrial filtration.

2. Replacement Solutions: Custom manufactured polypropylene filter plates are available to replace original stainless steel plates in vertical tower presses, offering cost-effective alternatives with highly efficient drainage surfaces to improve cloth life and performance.

3. Specialised Filtering: The Larox CC plate family includes Red and Orange ceramic filter plates designed for different applications, with Red plates featuring a monolithic membrane structure for high capacity, and Orange plates with a special fluorine-resisting formula for challenging environments emphasizing low cake moisture.

SAFETY HANDLING PRECAUTIONS

1. SAFETY PRECAUTIONS

Personal Protective Equipment (PPE): Always wear appropriate PPE, including safety goggles, hard hats, hearing protection, gloves, and steel-toed boots when handling or installing filter plates.

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

Lifting: Use appropriate lifting equipment for heavy plate components. Individual plates may weigh hundreds of kilograms, especially in larger presses.

Chemical Safety: For applications handling aggressive chemicals, material selection should be defined to meet process requirements.

Training requirement: Maintenance personnel must be properly trained on the safe and correct procedures for handling and installing filter plates 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.
