Product Overview
This combined crushing and sample division machine is an advanced integrated sample preparation system engineered specifically for continuous, multi-stage processing of coal and other bulk lump materials. By consolidating mechanical sieving, size reduction, and precise representative sample splitting into a single automated operational sequence, this system eliminates labor-intensive manual handling steps, significantly accelerates sample turnaround times, and minimizes potential human error in laboratory workflows.
Designed primarily for high-throughput testing environments, the equipment handles raw input lump feeds with exceptional efficiency. It is ideally suited for quality control laboratories across power generation facilities, coal mining operations, metallurgical processing plants, geological survey institutes, and third-party inspection agencies where processing high daily sample volumes with strict analytical reproducibility is paramount.
Constructed with dynamic balance stability, industrial-grade mechanical components, and heavy-duty structural reinforcement, this processing system delivers reliable performance under demanding industrial operating conditions. It provides high operational consistency, resistance to moisture-induced clogging, and long-term durability for continuous daily laboratory usage.
Key Features
- Integrated Three-Stage Processing: Continuously executes sequential sieving, primary/secondary crushing, and mechanical sample division in a single automated pass, eliminating multi-device sample transfers.
- Adjustable Output Particle Sizing: Features fine discharge granularity control ranging from 1 mm to 8 mm, allowing operators to easily tailor crushed material dimensions to exact downstream testing requirements.
- Fixed 1:8 Sample Division Ratio: Utilizes a precision mechanical splitter operating at a constant 1:8 ratio, ensuring fully representative, non-segregated sample fractions for analytical accuracy.
- Generous Feed Grain Allowance: Accepts direct feeding of raw lump materials up to 50 mm in size, reducing the need for preliminary manual pre-breaking or coarse sorting.
- Enhanced Moisture Adaptability: Capable of smoothly processing feed materials with total moisture content up to 11% (as-received basis) without internal accumulation, bridging, or system blockages.
- Optimized Shaft Speed: Operates at a stable main shaft velocity of 480 r/min, maximizing crushing energy transfer while preserving particle size uniformity and structural balance.
- Industrial Three-Phase Power Drive: Powered by a robust 1.5 kW electric motor operating on 380V AC 50Hz, delivering continuous high-torque performance for tough mineral aggregates.
- Compact Space-Saving Layout: Built with total outer dimensions of 1150 mm × 600 mm × 1200 mm, offering high functional integration within a small footprint suitable for standard lab layouts.
