Core Equipment Components
A standalone fully automatic heat treatment line can also be customized separately according to customer requirements, independent of the full casting line.
Automatic Molding & Pouring System
Fully automated metal mold handling and pouring system that ensures precise casting temperature and consistent ball formation, minimizing porosity and dimensional variation.
Medium-Frequency Induction Furnace
High-efficiency melting furnace with precise temperature and chemical composition control, ensuring stable alloy quality for each production batch.
PLC-Controlled Quench & Temper Furnace
Automated heat treatment system that delivers uniform hardness and refined microstructure, improving wear resistance and impact toughness of the finished grinding balls.
Automatic Sorting & Packing Line
Post-production sorting by size and weight, followed by automated packaging to ensure consistent product quality before shipment.
Technical Highlights
High Consistency
Automated process controls minimize batch-to-batch variation in hardness and chemistry.
Low Breakage Rate
Optimized heat treatment reduces micro-cracking and premature ball breakage.
Scalable Output
Line capacity can be adjusted to meet high-volume mining and cement industry demand.
Quality Traceability
Every batch is recorded and traceable via internal QC and third-party lab testing.
