In industrial solid-liquid separation, achieving the lowest possible moisture content in waste solids is often the primary engineering objective. A Frame Filter Press (also widely known as a Plate and Frame Filter Press or Chamber Filter Press) is an intermittent pressure filtration device used to separate solids from slurries.
Unlike continuous dewatering methods, an Industrial Frame Filter Press operates in batch cycles using high hydraulic pressure to force liquid through a filter medium, trapping solids inside recessed chambers. This technology is the gold standard for applications requiring high filtrate clarity and a stiff, stackable filter cake. For industries dealing with inorganic sludge, mining tailings, or chemical precipitates, this equipment offers the most efficient volume reduction method available, directly translating to lower disposal and transport costs.
We engineer various configurations to suit specific filtration areas and automation levels.
Chamber Filter Press (Recessed Plate):The most common configuration. It uses molded Polypropylene (PP) plates with a recessed center. When clamped together, these recesses form chambers where the cake builds up. It is robust, easy to operate, and ideal for standard wastewater dewatering.
Membrane Filter Press:This advanced version features flexible membranes on the plates. After the initial filtration cycle, water or compressed air is pumped behind the membrane to physically "squeeze" the cake. This secondary compression significantly reduces remaining moisture, often achieving cake dryness 10-15% higher than standard chamber presses.
Qingdao Yimei’s filter presses are built to withstand the rigorous mechanical stresses of high-pressure filtration.
Robust Structural Integrity: The main frame is constructed from high-quality Q235 carbon steel using submerged arc welding. This ensures the structure stays rigid and deformation-free even under closing pressures exceeding 20 MPa.
High-Performance Filter Plates: We utilize reinforced Polypropylene (PP) plates that resist acid and alkali corrosion. These plates are precision-molded to ensure a perfect seal, preventing leakage during the high-pressure filtration phase.
Automated Hydraulic System: Our units feature an integrated hydraulic station that automatically maintains the necessary closing pressure. Options for automatic plate shifting are available, which shakes the plates to discharge the cake without manual intervention, drastically reducing labor intensity.
Optimized Filtration Efficiency: By selecting the correct filter cloth (with micron ratings tailored to your particle size), our presses deliver crystal-clear filtrate that can often be reused directly in production processes.
While versatile, the Frame Filter Press excels in industries requiring high-solids capture and extremely dry cakes:
Mining & Metallurgy: Critical for dewatering tailings, coal washing slime, and metal concentrates. The press produces a dry cake that can be safely stacked or backfilled, mitigating environmental risks.
Ceramics and Stone Processing: Used to dewater kaolin clay and granite cutting sludge. The recovered water is recycled back to the cutting saws, creating a zero-discharge closed loop.
Chemical Manufacturing: Essential for separating pigments, dyes, and silica. In these scenarios, the "cake" is often the valuable product, not waste, requiring the high purity separation that only a filter press can provide.
Electroplating & Surface Treatment: Handles hazardous metal hydroxide sludge. The high dryness achieved ensures the hazardous waste weight is minimized, significantly lowering the cost of hazardous waste disposal fees.
Purchasing from a direct China Frame Filter Press Manufacturer like Qingdao Yimei offers distinct technical and commercial advantages:
Transparent Economics: We offer a factory-direct Frame Filter Press Price, eliminating distributor markups. Our quote includes the complete package: the frame, hydraulic station, pump integration, and control panel.
Lab-Tested Cloth Selection: The efficiency of a press depends entirely on the filter cloth. We encourage clients to send slurry samples to our lab. We test various cloth permeabilities and weaves to ensure your machine doesn't clog and delivers the clearest filtrate.
Long-Term Durability: We understand that filter plates and cloths are wear parts. Yimei maintains a massive inventory of replacement plates and customized cloths, ensuring your operation never stalls due to a lack of spare parts.
