Composite stone (engineered stone) performance depends on a stable mineral backbone. EB TA supplies physically beneficiated quartz materials designed to preserve the natural integrity of the ore while meeting industrial requirements for particle distribution, cleanliness, and repeatability — supporting controlled production behavior from mixing to pressing and finishing.
Quartz contributes mechanical strength, low water absorption behavior, and resistance to chemicals and heat — key properties for composite stone surfaces targeting long-term stability and consistent appearance.
EB TA supplies quartz across a wide PSD spectrum (micron to granular), enabling producers to engineer packing density, surface texture, and process stability according to their formulation strategy.
| Goal | Balanced packing, smooth finish, stable processing |
|---|---|
| Approach | Blend granular + fine powder fractions to optimize void filling and surface performance |
| Verification | PSD + moisture + bulk density controls under EB TA quality process |
Composite stone manufacturers often require continuity in whiteness and transparency, as well as low levels of undesired dark/yellow grains. EB TA quality controls are designed to support supply continuity and predictable visual output.
EB TA provides both granular and dry-ground powder forms to match different composite stone formulations and processing steps. Packaging and shipping can be organized according to operational logistics and volume requirements.
| Form | PSD / Control | Typical Role | Packaging |
|---|---|---|---|
| Granular Quartz | Engineered grain distribution (sieve / PSD verified) | Structural skeleton, texture control, packing | Big-Bag / Silo Truck |
| Powdered Quartz (Dry Ground) | Homogeneous distribution (laser PSD verified) | Void filling, smooth finish, formulation stability | Craft Bag / Big-Bag / Silo Truck |
Composite stone manufacturing typically requires controlled particle size distribution, stable material behavior, and repeatable supply quality to support predictable mixing, pressing, and finishing.
Both granular quartz and dry-ground powdered quartz are commonly used. Granular fractions help structure and texture, while powder fractions support void filling and surface smoothness.
Yes. EB TA supports industrial requirements with particle size engineering across micron-to-granular ranges and can align production to your technical specification.
Particle size distribution is verified through laser diffraction and sieve analysis, enabling batch-to-batch consistency for applications that require strict granulometry.
Consistency supports stable packing density, predictable resin/mineral interaction, and repeatable appearance—helping reduce process variability and quality deviations.
No. EB TA focuses on physical beneficiation methods to preserve the natural mineral structure while meeting targeted industrial specifications.
Quartz provides hardness, low water absorption behavior, and chemical/thermal resistance—supporting long-term stability in composite stone surfaces.
EB TA’s quality approach prioritizes repeatability and continuity. For surface-focused applications, customers typically request stable appearance characteristics and controlled unwanted grain levels.
Packaging options include Big-Bag and Silo Truck for granular materials, and Craft Bag / Big-Bag / Silo Truck for powder depending on logistics and volume.
