Product Overview
Sourced directly from our raw bentonite deposits in Northeast China, this mineral-based cat litter uses high-purity sodium clay without synthetic binders or added glues. The material is mechanically crushed and sieved into dense granules that react immediately on contact with liquids. Built specifically for private-label brands and volume buyers, our production lines maintain standard granule density and low ambient moisture across large batch runs, ensuring steady inventory supply for container-level orders.

Performance
01
Immediate Liquid Entrapment
When urine hits the granules, high-montmorillonite minerals expand instantly at the surface level. This fast horizontal swelling forms a shallow, hard disk before fluid reaches the bottom of the tray, keeping the litter box dry and making daily scooping straightforward.
02
Multi-Stage Dust Reduction
Our processing line runs raw granules through four mechanical vibration screens paired with negative-pressure air exhaust. Dust particles smaller than 100 mesh are continuously pulled out during crushing and packing, leading to clean pours with minimal airborne silt.
03
Natural Odor Neutralization
Instead of hiding smells with heavy artificial fragrance, the clay lattice holds ammonium ions chemically upon contact. For longer odor control in multi-pet homes, optional dark activated carbon granules can be dispersed to capture ambient organic gases.
04
Balanced Weight and Reduced Tracking
Granule size is strictly balanced between 0.5mm and 2.5mm. The resulting granule weight prevents particles from sticking to wet paws or fur, keeping stray sand localized inside the tray perimeter.
Applications
Retail Chains & Mass Merchants
Packed into durable 5L/10L polybags or rigid boxes designed for high stack strength, clean shelf presentation, and cost-efficient freight density.
Pet Specialty & E-Commerce Brands
Compatible with micro-granule formulations and custom scent infusions, tailored for premium brand positioning and online shipping packaging requirements.
Large-Scale Commercial Facilities
Available in 500kg or 1000kg bulk super-sacks for catteries, shelters, and re-bagging facilities requiring consistent volume and reliable lead times.
Every production lot undergoes lab testing for moisture level, absorption speed, and fine particle percentage prior to packaging. We supply complete shipping documentation for international customs compliance, including COA, Safety Data Sheets (SDS), heavy metal analysis reports, and non-hazardous cargo certifications.

Finished Product Warehousing
Raw materials undergo twin-shaft mixing with water added to achieve a moisture content of 16%–20%. (Note: Alkali addition is required for producing premium-grade products, whereas ordinary ore sand does not require it.)
The mixed raw materials are fed at a constant rate into a twin-roll extrusion machine to form cakes. These cakes are then stockpiled for a minimum of seven days before drying.
The extruded semi-finished products are fed into a dryer; the temperature is controlled to reduce the moisture content of the granules to 3%–5%.
The dried semi-finished products enter the crushing hopper and are conveyed via belt to a vertical-shaft crusher. The crushed granules are screened; those meeting the 1–2 mm or 1–4 mm specifications are collected in bulk bags, while granules larger than 4 mm are recirculated through the crusher.
The screened granules undergo a second drying process to reduce moisture to ≤3%. They then pass through a rotary screen for final sizing and are collected in bulk bags, awaiting coating and packaging.
Packaging is performed according to production order requirements. Before packaging, materials undergo vibrating screening for dust removal, and a "first-article inspection" is conducted; packaging proceeds only if the product meets quality standards regarding clumping and dust levels. During packaging, attention is paid to batch coding, bag weight, sealing, quantity, and the attachment of accurate identification tags.
Finished products are stored in the warehouse according to established protocols, sorted by product type and arranged neatly.

FAQ
Q: How do you prevent sodium bentonite from caking during long ocean transit in high humidity?
A: We keep moisture levels strictly below 8.0% during production. Finished bags are sealed in moisture-proof woven poly film with heavy-duty pallet shrink-wrapping. For sea freight across tropical routes, we add industrial desiccant bags inside each container to stop ambient humidity from causing premature clumping inside the sacks.
Q: What is the typical loading capacity per 20ft container for this mineral litter?
A: A standard 20ft container holds approximately 24 to 25 metric tons without pallets. If fully palletized for automatic forklift unloading, total capacity is around 20 to 22 metric tons, depending on individual bag sizes (e.g., 5L, 10L, or 10kg bulk bags).
Q: Can we adjust the fragrance blend or granule color mix for our private label orders?
A: Yes. Beyond unscented base clay, we can add micro-encapsulated scents (such as lavender, baby powder, or green tea) or mix in functional colored indicator beads (like blue silica or black activated carbon) according to your target market specifications.
Q: How does your factory verify that dust levels stay under 0.3% per batch?
A: Every batch passes through four stages of negative-pressure cyclone extraction before bag filling. Prior to loading, our QA lab runs gravimetric air-jet sieve tests on random samples to guarantee fine dust stays well below the 0.3% ceiling.
Q: Can you provide trial samples and official test documents for local customs clearance?
A: Absolutely. Free 1kg to 3kg testing samples are ready for courier dispatch upon request. Each container shipment includes a Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), and non-hazardous cargo declaration documents for easy clearance at destination ports.
