Cat Litter Production Process

Manufacturing Process by Type

Each cat litter type has a distinct manufacturing process. Understanding these processes helps B2B buyers evaluate supplier capabilities and quality control.

1 Tofu Cat Litter Production

Production Time: 180-240 minutes per batch

Raw materials: Pea fiber (40-50%), corn starch (30-40%), guar gum (5-10%).

  1. Raw Material Preparation: Ingredients weighed and mixed according to formulation
  2. Extrusion: Mixed material extruded at 120-150°C through diameter-specific dies (1.5/2.0/3.0mm)
  3. Cutting: Extruded strips cut into 5-15mm lengths
  4. Drying: Conveyor dryer reduces moisture from 30% to 8-10% (critical for clumping)
  5. Screening: Vibrating sieve removes fines and oversized particles
  6. Additives (Optional): Activated charcoal (0.5-1%), green tea powder, or deodorant mixed
  7. Packaging: Automated weighing and filling (2.5kg, 5kg, 10kg, 25kg bags)

Quality Checkpoints

Moisture content (8-10%), dust rate (<3%), clumping time (<10s), water absorption (>250%)

2 Bentonite Cat Litter Production

Production Time: 60-90 minutes per batch

Raw materials: Sodium bentonite clay (mined from Inner Mongolia or Turkey).

  1. Mining: Sodium bentonite clay extracted from open-pit mines
  2. Crushing: Large clay chunks crushed to <5cm pieces
  3. Drying: Rotary dryer reduces moisture to <8%
  4. Granulation: Crushed clay formed into spherical particles (0.5-2.5mm diameter)
  5. Screening: Multiple sieves separate different particle sizes
  6. Dust Removal: Air classifier removes fine dust particles
  7. Packaging: Bulk packaging (25kg woven bags) for cost efficiency

Quality Checkpoints

Particle size distribution, moisture (<8%), clumping time (<10s), dust rate (<15%)

3 Silica Cat Litter Production

Production Time: 120-180 minutes per batch

Raw materials: Silica sand + sodium carbonate (heated to 1300°C).

  1. Sodium Silicate Solution Preparation: Silica sand + sodium carbonate heated to 1300°C
  2. Acidification: Sulfuric acid added to precipitate silica gel
  3. Aging: Silica gel aged for 12-24 hours to stabilize structure
  4. Washing: Multiple water washes to remove sodium sulfate
  5. Drying: Spray dryer produces spherical beads (2-5mm diameter)
  6. Screening: Separation by size (fine, medium, coarse)
  7. Color Addition (Optional): Blue or pink indicators added

Quality Checkpoints

Bead size uniformity, absorption capacity (>80% weight), dust rate (<0.5%)

4 Mixed Cat Litter Production

Production Time: 150-200 minutes per batch

Raw materials: Pre-produced tofu litter and bentonite (or cassava) components.

  1. Component Preparation: Tofu litter and bentonite (or cassava) produced separately
  2. Blending: Two components mixed in 70:30 or 60:40 ratio
  3. Uniformity Check: Sample testing to ensure even distribution
  4. Additives (Optional): Charcoal or fragrance added during blending
  5. Packaging: Mixed litter packaged in composite bags (better moisture barrier)

Quality Checkpoints

Component ratio accuracy, clumping performance, dust rate (mixed)

Production Capacity & Lead Time

Factory scale determines daily output and lead time. Gormeet's 100-ton/day capacity ensures fast delivery.

Factory Scale Daily Capacity Lead Time (1 container) MOQ
Small (1-2 lines) 10-30 tons/day 15-20 days 10 tons
Medium (3-5 lines) 50-100 tons/day 10-15 days 10 tons
Large (6+ lines, like Gormeet) 100+ tons/day 7-10 days 10 tons

Quality Control Checklist for B2B Buyers

These checkpoints should be verified during factory visits or sample testing.

  1. Raw Material Inspection: Supplier certificates for pea fiber, corn starch, bentonite
  2. In-Process Control: Moisture meter, dust tester, clumping timer
  3. Final Product Testing: Water absorption (ISO 8460), dust rate (ASTM D5474), clumping strength
  4. Packaging Inspection: Weight accuracy, seal integrity, labeling correctness
  5. Third-Party Testing: SGS or Intertek report for international shipments
