Product Overview
This mechanized coke crushing and ball making machine represents the primary stage of standardized coke reactivity sample preparation systems. Engineered specifically for metallurgical testing laboratories and industrial coking operations, the unit applies precision mechanical cutting and dual-action grinding principles to transform raw lump coke into uniform square polyhedral blanks. By mechanizing the initial size-reduction process, this equipment eliminates manual trimming variability while preserving structural integrity for downstream spherical polishing.
Designed to seamlessly integrate into quality control workflows, this system serves steel manufacturers, commercial assay laboratories, and merchant coke plants preparing samples for Coke Reactivity Index (CRI) and Coke Strength after Reaction (CSR) determination. Processing feed lumps up to 100 mm down to a precise discharge dimension of 23 mm or greater, the unit ensures representative sample preparation with minimal volume consumption, reducing the volume of bulk material required for testing protocols.
Built for high-volume laboratory and industrial environments, the heavy-duty structural design withstands continuous abrasive stress and impact loading. The stable high-torque drive mechanism and wear-resistant cutting assemblies deliver exceptional operational uptime, low maintenance overhead, and outstanding specimen yields across varying coke ranks and matrix porosities.
Key Features
- Dual-Action Mechanical Cutting and Grinding: Incorporates hardened cutting blades and precision grinding mechanisms that break coke lumps along natural fissures, shaping irregular pieces into symmetrical polyhedral blanks without inducing excessive micro-fractures.
- Optimized High-Yield Specimen Recovery: Engineered tool geometry and controlled feed kinematics dramatically raise the usable specimen yield rate compared to manual knapping or standard jaw crushers, ensuring maximum recovery of test-ready core material.
- Reduced Sample Material Requirements: Precise mechanical dimensional reduction allows laboratories to extract required test cores from minimal raw sample volumes, optimizing testing turnaround and conserving representative exploration or batch samples.
- Significant Labor and Fatigue Reduction: Fully replaces hazardous and physically demanding manual chipping, chiseling, and hammer-trimming with an automated push-button process that enhances operator safety and productivity.
- High-Power Industrial Drive Assembly: Driven by a robust 5.5 kW industrial-grade motor that maintains continuous cutting torque under severe resistance, preventing stalling when processing dense, high-strength metallurgical coke.
- Standardized Three-Phase Electrical Compatibility: Operates on standard 380V AC three-phase power at 50Hz, featuring heavy-duty switchgear and integrated thermal overload protection for seamless facility integration.
- Heavy-Gauge Reinforced Housing: Fabricated from structural-grade plate steel with high-integrity welded joints, dampening operational vibration and resisting the relentless wear of abrasive coke particulate.
- Foundational Integration in 3-Stage System: Engineered as the essential initial unit of the comprehensive three-machine coke ball preparation sequence, establishing uniform feed geometry for subsequent secondary rounding and tertiary spherical finishing machines.

Why Choose This Product
- Consistent Sample Quality for Critical Testing: Manual sample chipping inevitably introduces operator bias, irregular cleavage planes, and microscopic cracks that artificially degrade CRI and CSR results. This system standardizes the rough-shaping process, yielding identical polyhedral blanks that ensure downstream test repeatability.
- Exceptional Material Efficiency: By utilizing focused cutting and grinding forces rather than indiscriminate compressive crushing, the machine maximizes the percentage of whole polyhedral cores obtained from each sample charge, dramatically reducing wasted coke volume.
- Rugged Industrial Engineering: Powered by a 5.5 kW continuous-duty drive train and lined with high-strength components, the equipment is purpose-built to process tough, highly abrasive carbon materials in harsh laboratory and industrial environments without mechanical failure.
- Turnkey Integration into 3-Machine System: Specifically optimized to serve as the critical front-end link in standard three-stage mechanized coke balling systems, ensuring seamless mechanical compatibility and dimensionally verified output for secondary rounding stages.
- Operator Health and Safety Enhancement: Enclosed cutting chambers and automated feeding mechanisms keep dust contained and remove operators from hazardous manual cutting, reducing workplace injuries and repetitive strain fatigue.
