Manufacturing Process Flow of Ceramcast Sand Ball Shape
The production of Ceramcast sand ball shape involves a carefully controlled, multi-stage process to ensure consistent quality and superior performance:
1. Raw Material Selection & Preparation
High-purity bauxite ore is meticulously selected for its Al2O3 content and low impurity levels. This raw material undergoes initial crushing and grinding to achieve a specific particle size distribution suitable for the subsequent processing stages. Strict incoming quality control ensures material consistency.
2. Granulation & Shaping
The prepared bauxite powder is then mixed with specific binders and carefully granulated in specialized equipment to form spherical pellets. This stage is crucial for achieving the characteristic ball shape and initial mechanical strength, which are vital for mold packing density and flowability.
3. High-Temperature Sintering
The green pellets are subjected to high-temperature sintering in rotary kilns, typically exceeding 1500°C. This process densifies the material, eliminates volatiles, and transforms the bauxite into a robust ceramic structure with exceptionally high refractoriness and chemical inertness. Precise temperature control is critical here.
4. Screening & Classification
After cooling, the sintered sand is screened and classified into precise grain size distributions (e.g., AFS GFN values). This ensures uniformity, which is vital for consistent mold permeability and surface finish. Oversized or undersized particles are removed or re-processed.
5. Quality Control & Packaging
Every batch undergoes rigorous quality control testing in accordance with international standards (e.g., ISO 9001, ANSI/AFS standards). Parameters like AFS GFN, sphericity, bulk density, refractoriness, and chemical composition are verified. The finished Ceramcast sand is then packaged for distribution, ready for foundries looking for premium casting sand for sale.
