Product Overview
Our Mixed Mineral Cat Litter is engineered by combining high-purity sodium bentonite, natural zeolite, and activated carbon sphere particles into a unified performance formula. By blending multi-pore functional minerals, this formula addresses the two biggest pain points in the pet market: immediate odor trapping and instant moisture lock. Developed at our Liaoning manufacturing base, it offers exceptional clumping strength, low dust emissions, and reliable supply chain stability for global importers, distributor networks, and private label brands.

Why Global Importers Choose Hengjie
Fully Integrated Supply Chain
Operating directly near high-quality mineral deposits allows us to control cost, purity, and grain consistency from the pit to the final packaged bag.
Strict Quality Assurance (QA)
Every batch undergoes strict quality control checks before loading, including drop tests for finished bags, moisture checks, clumping speed verification, and dust concentration analysis.
Optimized Container Loading Efficiency
We design custom master carton configurations and pallet loading schemes that maximize volume utilization per 20ft and 40ft HQ container, reducing your landed freight cost per unit.

Key Functional Performance
Instant Clumping Power: Hydrophilic sodium bentonite binds urine into solid, compact clumps within 3 seconds, preventing loose residue and eliminating tray sticking.
Dual-Layer Odor Control: Activated carbon spheres trap sulfur molecules while natural zeolite locks ammonium ions, providing continuous, long-lasting odor containment without heavy artificial fragrances.
Superior Anti-Crushing Granules: Multi-step screening and heat processing increase particle hardness, resisting transportation crushing and reducing tracking around the litter box.
Smart Litter Box Compatibility: Optimized particle size distribution ensures seamless operation with popular automatic self-cleaning litter units without clogging the sifting mechanism.

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 are the main advantages of ordering mixed mineral cat litter over standard bentonite or tofu cat litter?
A: A multi-mineral formula combines the physical benefits of different substrates. Standard bentonite clumps well but can lose odor absorption efficiency over time. Tofu litter offers low dust and flushability but can degrade under high humidity. Mixing sodium bentonite with zeolite and activated carbon creates a balanced product that clumps quickly, controls ammonia longer, and maintains structural integrity across diverse regional climates.
Q: Can we customize the ratio of activated carbon and zeolite for our private label brand?
A: Yes. As an OEM manufacturer, we can adjust the percentage of activated carbon spheres, deodorizing beads, and zeolite granules based on your target market requirements, price positioning, and functional claims.
Q: How do you prevent dust accumulation during long-distance maritime shipments?
A: Our production process incorporates a 12-stage negative-pressure dust extraction process during screening. Additionally, we apply a physical surface-hardening treatment to the mineral granules to prevent friction-induced breakdown inside the bags during ocean transport and handling.
Q: What packaging options are available for bulk OEM/ODM orders?
A: We offer a wide range of packaging options, including 3.8L/5L/10L stand-up vacuum pouches, side-gusset bags with handles, flat-bottom box pouches, and large 20kg/25kg woven sacks for local repacking. All film structures can be customized for high puncture resistance and high-definition rotogravure or flexographic printing.
Q: Is this mineral mix suitable for automatic self-cleaning litter boxes?
A: Yes. The particle size distribution (0.5–2.5mm) is specially tuned to pass through standard automated sifting grates cleanly. The fast-clumping reaction prevents wet clay from sticking to the rubber interior liners of automatic litter boxes.
