Product Overview
Liaoning Hengjie Pet Products Co., Ltd. operates integrated sodium bentonite reserves and multi-stage processing lines in China. We supply global distributors, brand owners, and retail chains with engineered mineral litter engineered for high absorbency, structural clump integrity, and dust containment. Contact our technical sales team for container pricing, custom blending specs, and sample evaluation.
Our composite litter combines raw sodium bentonite with porous mineral granules. This blend stabilizes liquid uptake across varying humidity conditions while maintaining high container-load efficiency.

Performance Characteristics
01
Dual-Action Moisture Absorption & Fast Aggregation
The natural sodium bentonite expands upon contact with liquid, forming compact disks within seconds. Adding structured mineral particles speeds up fluid drainage toward the center of the clump, preventing liquid from reaching the bottom of the tray. This preserves litter freshness and lowers overall consumption per cat box.
02
Multi-Stage Dust Extraction System
Fine dust creates customer complaints and clogs high-speed automated bagging equipment. Our production line incorporates three separate negative-pressure vacuum extraction points during crushing, grading, and packaging. The final product stays clean during transit, pouring, and daily use.
03
Natural Odor Retention Without Heavy Perfumes
The porous lattice structure of the mineral granules traps volatile organic compounds and ammonia molecules through physical adsorption. Retailers can market a high-performance unscented product or select from our subtle, micro-encapsulated fragrance options that maintain long shelf life.
04
Reduced Package Breakage & Shipping Stability
Traditional clay litters often crush into powder under container stacking pressure. Our calcined mineral blend reinforces granule rigidity, drastically reducing fine-powder generation caused by ocean transport friction and pallet compression.
OEM/ODM Supply Solutions
Factory Direct Private Labeling
We offer complete artwork layout assistance, bag printing plate management, and structural bag selection (including flat-bottom pouches, quad-seal bags, and heavy-duty woven plastic bags with soft rubber handles).
Tailored Particle Blending
Depending on your regional price tier, we can adjust the ratio between natural bentonite, porous mineral granules, activated charcoal pellets, or colored indicator beads to create distinct mid-range or super-premium retail product SKUs.
Optimized Container Loading Dynamics
Our packing teams utilize specialized stacking configurations and slip-sheet/pallet combinations to maximize payload weight while preventing bottom-bag burst during long ocean voyages and port transshipment.
North American / European Retail Chains: High emphasis on dust-free performance (≤ 0.5%) and FSC-compliant or recyclable packaging materials. Our Bentonite And Mineral Cat Litter passes stringent airborne particle counts to suit indoor living spaces.
Middle East & High-Humidity Regions: Focus on shelf-life stability and moisture resistance. Our low initial moisture content (≤ 6.0%) prevents premature caking inside warehouse storage under elevated humidity levels.
E-Commerce & Mail-Order Brands: Requires packaging with high bursting strength to survive postal sorting machines and drop-testing standards. We offer reinforced multi-layer PE packaging specifically tested for courier shipping environments.

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: What makes the sodium bentonite and functional mineral blend superior to single-component clay litters?
A: Single-component clay often forms soft clumps when saturated quickly or releases heavy dust under strain. By fusing high-purity sodium bentonite with porous, crushed volcanic minerals, our composite litter balances rapid surface absorption with structural clump strength. The mineral matrix speeds up downward liquid channelization, preventing wet spots from sticking to the tray bottom while reducing overall material consumption by roughly 15% per box fill.
Q: How does this mineral composite perform during long-distance ocean shipping and storage?
A: Freight vibration and humidity variations during international transport often degrade standard clay granules into fine powder. Our mineral particles undergo a high-temperature calcination treatment that raises granule hardness. Combined with multi-stage air extraction before bagging, the litter maintains structural integrity through container handling, transit, and warehouse stacking without crushing or packing down.
Q: What is the fine dust percentage, and how is it tested before shipment?
A: We enforce a strict finished-goods dust threshold of equal to or less than 0.35% by dry weight. Every production lot passes through a three-stage negative-pressure air elutriator prior to packaging. Quality assurance inspectors verify particle stability using mechanical sieve shaker testing and air-flow filtration meters. A batch-specific Certificate of Analysis (COA) is included with each container shipment.
Q: Can we adjust the particle ratio and granule sizing for specific regional markets?
A: Yes. We customize mesh cut sizes (ranging from 1.0 mm to 3.5 mm) and mineral blending ratios to match local consumer preferences. For example, tighter granule spreads (1.0 mm – 2.2 mm) suit automatic self-cleaning litter boxes, whereas broader cuts (1.5 mm – 3.2 mm) work better in humid tropical climates to maximize airflow between granules and limit tracking.
Q: What private-label packaging options offer the best protection against moisture ingress?
A: For overseas ocean freight, we recommend heavy-duty PET/PE laminated stand-up pouches with zip closures or vacuum-sealed side-gusset bags. We also supply 1000 kg woven FIBC jumbo bags with internal PE moisture liners for distributors operating localized re-bagging facilities. Our loading team optimizes pallet dimensions to maximize net container payload for both 20ft and 40ft HQ shipments.
