Working Principle
What Is A Disc Filter?
An industrial disc filter (also known as a rotary vacuum disc filter) is a continuous dewatering plant designed for rapid solid-liquid separation of heavy mineral slurries. It consists of multiple independent vertical filter discs mounted on a horizontal rotating shaft, partially submerged in a slurry vat, using controlled vacuum pressure to extract liquids while accumulating thick solid particles onto the cloth sectors.
Zhonghui Machinery vacuum filtration designs prioritize optimal hydraulic efficiency, quick sector replacement mechanisms, and uniform cake distribution under heavy mineral processing workloads.
Ideal Applications & Slurry Processing:
Mineral Ore Dewatering: Processing iron ore concentrates, copper tailings, gold flotation slurries, and coal fines washings.
Chemical & Metallurgical Plants: High-efficiency recovery of metal oxides, industrial chemical precipitates, and chemical salts.
Environmental Wastewater: Solid recovery from heavy industrial sludge, tailings management, and recycling water treatment networks.

FREQUENTLY ASKED QUESTIONS
EVERYTHING YOU NEED TO KNOW
Find expert answers to the most common questions about our disc filter installations, including cloth longevity, vacuum pump requirements, and slurry density guidelines.
Q1: What are the main advantages of a disc filter over a drum filter?
A: A disc filter provides a much larger filtration area within the exact same workshop footprint because its filter panels are stacked vertically. This makes it highly compact, cost-efficient, and ideal for high-capacity mineral concentrate dewatering plants where floor space is limited.
Q2: How do you choose the right filter cloth material for different slurries?
A: Cloth selection depends on slurry particle size, acidity, and temperature. We supply premium monofilament or multifilament synthetic fabrics (such as polypropylene, polyester, and nylon) woven with specific pore diameters to maximize solids recovery while preventing premature blinding.
Q3: What typical cake moisture level can this filtration equipment achieve?
A: For standard metal ore flotation concentrates like iron, copper, or lead, our vacuum disc filter systems regularly achieve stable output cake moisture levels between 9% and 15%, depending on the mineral fineness distribution and slurry feed density.
Q4: Why does the filter vat include a mechanical agitation system?
A: High-density mineral ores settle rapidly due to gravity. Our plant integrates an automated horizontal paddle agitation shaft at the bottom of the vat, keeping the solids perfectly suspended to guarantee uniform cake thickness on every rotating disc sector.
Q5: Are the individual disc sectors easy to repair or replace?
A: Yes. Every disc is divided into 10 to 12 individual pie-shaped wedge sectors made of high-strength structural plastic or stainless steel. If a single cloth tears, operators can quickly swap out just that one sector without dismantling the remaining plant structure.
Q6: Do you supply the matching vacuum pumps and filtrate receivers?
A: Yes, absolutely. Zhonghui Machinery provides complete turnkey liquid-solid separation packages. This includes liquid-ring vacuum pumps, filtrate separation receivers, barometric blow-back air tanks, and continuous filtrate discharge pumps sized for your plant elevation.
Q7: What is the typical factory order manufacturing timeline?
A: Standard vacuum filtration units take approximately 25 to 35 calendar days to complete precision shaft machining, vat fabrication, distribution valve balancing, and factory hydraulic leak testing.
