Do you offer automatic cloth washing for sticky cathode materials?

Yes. We provide high-pressure automatic cloth washing systems operating at up to 100 bar. A robotic spray bar travels between the plates to remove sticky residues such as LFP or ternary precursors, restoring filtration speed and ensuring consistent cycle times without manual cleaning.

Can we expand the capacity of the press later if production scales up?

Yes. We can design the filter press with an expandable head and extra beam length. This allows you to start with fewer plates and add more plates later to increase capacity without purchasing a new machine, which is ideal for phased production ramp-ups.

New Energy: Battery-Grade Filtration

Q: How do you guarantee iron-free operation?

We clad the main beam in stainless steel 304 and use special coated bolts, non-metallic chain guards, and polymer wear strips on the plate handles. This design ensures that even in the event of friction, no iron particles can contaminate the product.

Q: Can your plates withstand pH 14 at 80°C?

Standard polypropylene plates may soften under these conditions. For high-pH and high-temperature applications such as lithium hydroxide processing, we use glass-fiber reinforced polypropylene (R-PP) or PVDF plates, which maintain rigidity and chemical resistance at elevated temperatures.

Q: What is the separation accuracy for silicon powder?

We use precision monofilament filter cloths with pore sizes down to 1–2 microns. When combined with an optimized feed pressure profile, this achieves greater than 95% capture efficiency for fine silicon carbide (SiC) particles.

Q: What filter cloth do you recommend for sub-micron precursor particles?

For ultra-fine particles in the 0.5–2 micron range, we recommend specialized multifilament or satin-weave filter cloths. These provide high capture efficiency while still allowing good cake release compared to standard felt cloths. Sample swatches can be provided for laboratory testing.

The Core Challenge: Purity is Power

In New Energy manufacturing, even micron-level contamination can cause battery failure.

Magnetic Impurities: Zero tolerance for Iron (Fe), Copper (Cu), or Zinc (Zn) particles in cathode materials.
High-Value Loss: Inefficient separation means losing expensive Lithium or Cobalt in the waste stream.
Aggressive Chemistry: Production involves strong alkalis (pH 14) and acids (H₂SO₄) at high temperatures.

The Loway Solution: Two Lines of Defense

We offer specialized equipment for both your Production Line and your Plant Utilities.

Best For: Precursor Washing, Lithium Carbonate, Anode/Cathode Materials.

The Tech:

Iron-Free Design: All contact surfaces are clad in SS304/316L or coated with Epoxy/Halar. We use non-metallic piping and wear strips to ensure Zero Magnetic Pollution.
30 Bar Squeeze: High-pressure membrane squeezing produces ultra-dry cakes, reducing downstream kiln energy costs.
Smart Washing: Multi-stage counter-current washing recovers >99.5% of Lithium/Cobalt ions.

Best For: General Plant Sewage, Canteen Waste, Washing Tower Blowdown.

The Tech:

Low Cost Utility: While not for product contact, the Screw Press is the most energy-efficient tool for treating the factory’s general wastewater sludge. It runs 24/7 with minimal attention.

Technology Selection: Matching the Tool to the Zone

Q1: How do you guarantee "Iron-Free" operation?

We clad the main beam in Stainless Steel 304. We use special coated bolts, non-metallic chain guards, and polymer wear strips on the plate handles. This ensures that even if there is friction, no iron particles fall into your product.

Q2: Can your plates withstand pH 14 at 80°C?

Standard PP might soften. For these conditions (common in Lithium Hydroxide), we use Glass-Fiber Reinforced Polypropylene (R-PP) or PVDF plates, which maintain rigidity and chemical resistance at high temperatures.

Q3: What is the separation accuracy for Silicon powder?

We use precision monofilament cloths with a pore size down to 1-2 microns. Combined with the right feed pressure profile, we achieve >95% capture rate for fine Silicon Carbide (SiC) particles.

Q4: Do you offer automatic cloth washing? Sticky cathode materials often blind the cloth.

Yes. We provide high-pressure Automatic Cloth Washing systems (100 bar). A robotic spray bar travels between the plates, blasting away sticky residues like LFP or ternary precursors. This restores filtration speed without manual labor, ensuring consistent cycle times 24/7.

Q5: Can we expand the capacity of the press later if our production scales up?
Yes. We can design the frame with an “Expandable Head” (extra beam length). This allows you to start with fewer plates (e.g., 50 plates) and simply add more plates later (e.g., up to 80 plates) to increase capacity without buying a new machine. This is ideal for phased Gigafactory ramp-ups.

Q6: What filter cloth do you recommend for sub-micron precursor particles?

For ultra-fine particles (0.5 – 2 microns), we use specialized Multifilament or Satin-Weave cloths. These offer a tighter weave for high capture efficiency while still allowing for excellent cake release (“cake discharge”) compared to standard felt cloths. We can send sample swatches for your lab testing.
