1. Product Overview & Strategic Value for Stone Plants
In modern stone processing facilities-encompassing granite slabbing, marble gang sawing, bridge cutting, and continuous polishing lines-massive volumes of water are required to lubricate diamond saw blades, prevent thermal stress, and suppress hazardous respirable silica dust. However, this process generates dense, highly abrasive wastewater loaded with fine mineral slurry, quartz particles, calcium carbonate, and metal bond powder.
Environmental & Operational Risk: Discharging untreated stone wastewater violates environmental regulations, damages municipal drainage infrastructure, and incurs hefty regulatory fines. Furthermore, hauling wet slurry by tanker trucks is cost-prohibitive.
The Stone Wastewater Filter Press (Model KDYLJ-1000 Automatic Quick-Opening Filter Press), engineered by Kaida Stone Machinery, is an industrial-grade solid-liquid separation system specifically developed for the stone and mining industries. Featured under KAIDA's Pro-environment Machine series, the KDYLJ-1000 is engineered to dewater thick stone slurry under high mechanical pressure, compressing loose mud into dense, dry filter cakes while recovering up to 90%–95% of process water. The filtered water is clarified for direct closed-loop reuse across factory workshops, enabling stone processors to achieve zero wastewater discharge and drastically reduce fresh water procurement costs.

Core Strategic Benefits for B2B Processors
Zero Wastewater Discharge & Closed-Loop RecyclingPurifies abrasive stone wastewater into clear industrial-grade water, directly recirculated to gang saws, block cutters, and polishing lines. |
Significant Waste Volume ReductionSqueezes sludge into compact, 50 mm thick solid cakes with low residual moisture (15%–20%), making them easy to stack, transport, or sell as raw material for brick and cement manufacturing. |
High Throughput with 115 m² Filtration AreaEquipped with 60 high-strength circular chambers, delivering continuous dewatering capacity for medium-to-large stone fabrication yards. |
Rapid Plate Separation CycleThe automatic quick-opening mechanism opens all 60 plates in rapid succession, reducing cake discharge time from over 15 minutes down to under 3 minutes per cycle. |

3. Working Principle & 5-Stage Filtration Cycle
The KDYLJ-1000 operates via a semi-automated, pressurized batch filtration cycle designed to extract clear filtrate while compressing mineral slurry into dry, handleable cakes:
| Stage 1: Hydraulic Clamping (< 3.0 MPa Cylinder Pressure) | Stage 2: High-Pressure Slurry Feeding (< 2.0 MPa Chamber) |
| Stage 3: Cake De-watering & Solid-Liquid Separation | Stage 4: Automatic Quick-Opening & Cake Release |

4. Key Machine Configuration & Structural Advantages
|
|
 |
1. Circular Filter Plate Design (Φ 1,000 mm × 80 mm)
Unlike conventional rectangular or square filter plates that experience stress concentration at the four corners under high pressure, the KDYLJ-1000 features Φ 1,000 mm circular filter plates.
- Uniform Radial Stress Distribution: Circular plates distribute internal slurry pressure (< 2.0 MPa) evenly in 360 degrees, eliminating corner cracking and plate warpage.
- Extended Service Life: Fabricated from high-density, modified reinforced polypropylene (RPP), the 80 mm thick plates exhibit superior resistance to abrasion, acids, alkalis, and mechanical fatigue.
2. Automatic Quick-Opening Linkage Mechanism
Traditional manual or semi-automatic plate shifters move plates one by one, requiring 15 to 25 minutes of operator labor per batch. The KDYLJ-1000 utilizes an automatic quick-opening linkage system that opens multiple chambers simultaneously. This reduces plate separation time to under 3 minutes, drastically increasing daily batch cycles and overall factory throughput.
3. High-Efficiency 4 kW Hydraulic Power Station
Equipped with a precision hydraulic cylinder, pressure relief safety valves, and an automated pressure-holding circuit. Once clamped to the operating threshold (< 3.0 MPa), the system maintains positive plate seal pressure without continuously running the motor at full load, reducing electrical energy consumption.
4. Rigid 8.5-Ton Structural Steel Frame
With an overall installation footprint spanning 11,800 mm in length, the structural side beams and thrust plates are fabricated from heavy-duty structural steel, stress-relieved, and coated with multi-layer anti-corrosive industrial epoxy paint to endure humid, abrasive stone plant environments.
5. High-Tensile Polypropylene Filter Cloths
Tailored specifically for abrasive mineral slurries, the woven monofilament/multifilament filter cloths feature smooth surface characteristics that facilitate complete cake release, prevent fabric blinding, and ensure high water flow rates.
5. Factory System Integration: Complete Water Treatment Workflow
The KDYLJ-1000 is typically deployed as the central dewatering unit within an automated stone factory wastewater treatment plant (WWTP):
- Wastewater Collection Pit: Slurry effluent from gang saws, bridge cutters, and polishing lines drains via floor gutters into a primary collection pit equipped with coarse screens to intercept large stone chips.
- Cyclone Desanding Unit: An optional hydrocyclone removes coarse silica and rock grains (> 0.5 mm) to protect downstream pumps from premature impeller wear.
- Deep Cone Thickener / Sedimentation Tower: Slurry is pumped into a vertical cone clarifier where automated dosing systems introduce flocculant (Polyacrylamide / PAM). Flocculation rapidly settles suspended particles to the cone bottom, while clear water overflows into the clean reservoir.
- Sludge Buffer Sump: Concentrated bottom sludge (15%–30% solids) gravity-discharges into a buffer pit equipped with a low-speed mechanical agitator to prevent settling.
- KDYLJ-1000 Dewatering Unit: High-pressure slurry pumps feed the thickened mud into the KDYLJ-1000, producing dry 50 mm cakes and extracting remaining clear water.
