Product Overview
This enclosed automatic sample divider is an advanced electromechanical system engineered for precise, unbiased division of bulk granular materials. Driven by an electric motor coupled to a worm gear speed reducer and a crank-connecting rod mechanism, the equipment imparts continuous, uniform reciprocating motion to the dividing assembly. As raw material is introduced through the top feed inlet, it flows through the splitting mechanism to automatically yield representative analytical fractions, reserving required sample portions while routing excess material into a dedicated reject receptacle without manual intervention.
Specially designed for demanding laboratory sample preparation environments, this system processes a wide array of granular feeds including coal, iron ore, sinter, pellets, coke, construction aggregates, and chemical materials. It is widely adopted across mining facilities, metallurgical plants, power generation stations, construction material testing laboratories, commercial third-party inspection agencies, and scientific research institutes requiring strict adherence to international sample preparation standards.
Built to handle high-moisture samples up to 18% total moisture without clogging or cross-contamination, the unit features a fully sealed enclosure that prevents dust leakage and preserves sample integrity. Heavy-duty structural components and a robust mechanical drive deliver long-term operational stability, consistent division ratios, and uncompromised repeatability across intensive daily testing schedules.
Key Features
- Fully Enclosed Dust-Tight Housing: The complete mechanical assembly is encased within a heavy-duty sealed enclosure, effectively containing airborne dust, preserving moisture content, and protecting laboratory personnel from fine particulate exposure.
- Precision Reciprocating Splitting Mechanism: Powered by a worm gear reducer and crank-connecting rod linkage, the divider executes smooth, steady reciprocating passes across the falling material stream to ensure unbiased sampling.
- Adjustable Sample Division Ratios: Equipped with a user-friendly division ratio control knob on the divider body, operators can quickly select division ratios such as 1/2, 1/4, 1/8, or 1/16 to match specific analytical guidelines.
- Dual Chute Collection System: Features separate internal chutes that direct split fractions into dedicated reserve sample buckets and reject sample containers, eliminating sample mixing and speeding up post-processing workflows.
- High Moisture Compatibility: Engineered with optimized material contact surfaces and steep interior discharge angles, the system reliably processes moist granular samples up to 18% total moisture without clogging or material build-up.
- Industrial Heavy-Duty Drive Motor: Fitted with a robust 380V electric motor, the drive assembly delivers constant torque and dependable performance under continuous high-capacity operations.
- Direct Vertical Gravity Feed: Material enters directly into the splitting cutter from the top inlet, ensuring equal probability distribution across cutter openings and eliminating particle size segregation during feeding.
- Vibration-Dampened Structural Base: A rigid, low-profile frame minimizes operational vibration and noise while occupying a compact footprint in congested laboratory environments.
