PRIMARY USES
1. Large-Scale Industrial Filtration and Slurry Dewatering
Primary Use: High-performance filter plates form the core of FLSmidth Automatic Filter Presses and are used for solid-liquid separation in large-scale mining, mineral processing, and industrial applications. Essential for dewatering mineral concentrates, tailings, and other process slurries to recover valuable solids and produce clean water.
How it helps: For process engineers and plant operators, FLSmidth filter plates deliver efficient cake formation and filtration performance across a wide range of applications. The innovative Maxa™ Filter Plate, developed specifically for the M1500 and M2020 AFP series, delivers up to 10% more volume, improved filtration times, and a longer plate lifecycle compared to conventional designs. The plates are available in sizes from 900 x 900 mm up to 2500 x 2500 mm, with recessed or membrane plate configurations to suit specific process requirements.
2. Advanced Plate Technology for Improved Performance
Primary Use: FLSmidth filter plates feature optimised geometry and engineering to resolve common issues related to plate performance, including area, volume, flow, and durability.
How it helps: The Maxa Filter Plate incorporates several design enhancements: expanded filtration surface area improves throughput; greater chamber volume allows for increased cake mass per cycle; increased filtrate port area reduces velocity of filtrate and cake blow air, extending plate life; and engineered port locations and size promote filtrate flow while eliminating areas that fatigue filter media. The streamlined plate anatomy addresses common points of cloth failure, with air for cake blow introduced at lower velocity to reduce abrasion and improved pip design providing more consistent cloth support.
SECONDARY USES
1. High-Volume Tailings Treatment: The AFP2525 filter press processes up to 300 tonnes per hour with a single filter, delivering up to 95% water recovery and less than 10% residual moisture in filter cake.
2. Chemical and Industrial Filtration: Applications include wastewater treatment, pulp and paper, food processing, pharmaceutical production, and chemical manufacturing.
3. High-Temperature Applications: Special materials including high-temperature polypropylene and Kynar are available for applications requiring elevated temperature resistance.
4. Corrosive Environments: Stainless steel and non-ferrous metal plate materials are available for aggressive chemical applications.

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.
Access: Use integrated maintenance platforms for safe access. Overhead beam designs offer better visibility and access to plates, improving safety during maintenance.
Training requirement: Maintenance personnel must be properly trained on the safe and correct procedures for handling and installing filter plates on the specific FLSmidth 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.
Inhalation: If chemical fumes or dust are inhaled, move to fresh air. If symptoms persist (coughing, difficulty breathing), seek medical attention.
3. FIRE FIGHTING MEASURES
Flammability: Filter plates (polypropylene) are combustible. Use extinguishing media appropriate for plastic fires. Electrical equipment may be involved.
Extinguishing Media: Use water spray, foam, dry chemical powder, or carbon dioxide (CO₂) for fires involving filter plates or electrical equipment.
Fire Response: In the event of a fire, evacuate the area and call emergency services. Use appropriate extinguishers.

Hammer Mill
A Hammer Mill is an industrial grinding machine used to crush, pulverize, shred, and reduce the size of various materials such as grains, biomass, minerals, and agricultural products. It operates by rotating hammers attached to a spinning rotor that strike the material, breaking it down into smaller pieces which pass through a screen for size control. Hammer Mills are widely used in feed production, biomass processing, recycling, and mineral processing due to their efficiency and versatility. They come in various sizes and configurations, suitable for fine to coarse grinding and are essential in agriculture, manufacturing, and energy industries.
Hand Rotary Barrel Pump
A hand rotary barrel pump is a manually operated pump designed to transfer liquids, typically from barrels or containers, through a rotary pumping mechanism. The pump is equipped with a hand crank or lever that, when turned, activates a rotary gear or vane system inside the pump. This rotary action creates suction, allowing the pump to draw liquid from the source container and then dispense it through a spout or nozzle. Hand rotary barrel pumps are commonly used for transferring various fluids such as oils, fuels, chemicals, and other non-corrosive liquids. They offer a portable and efficient solution for applications where a power source may be unavailable or impractical.

Milking Machine
A Milking Machine is a mechanized system designed to extract milk from dairy animals such as cows, goats, and sheep in an efficient, hygienic, and consistent manner. It typically consists of a vacuum pump, pulsator, teat cups, milk container, and tubing system. The machine works by creating a vacuum that gently draws milk from the animal's udder through the teat cups and collects it into a sealed container, minimizing contamination. Milking machines improve milking speed, reduce manual labor, and enhance udder health by maintaining a uniform milking routine. They are essential in dairy farming operations of all scales—from smallholder farms to large commercial dairies—where consistency and hygiene are critical for milk production.
Stone Crusher
A stone crusher is a heavy-duty machine designed to reduce large rocks into smaller stones, gravel, or rock dust for use in construction, road building, and other aggregate applications. These machines use mechanical force to break down stone material, typically through compression or impact. Stone crushers come in various types such as jaw crushers, cone crushers, impact crushers, and hammer crushers, each suited to specific crushing requirements. They are widely used in mining, quarrying, construction, and recycling industries to produce consistent aggregate sizes for foundations, concrete, asphalt, and more.
