Product Overview
Engineered for high-throughput laboratory sample preparation, this heavy-duty unit seamlessly integrates rapid impact comminution with mechanical sample division into a single, fully enclosed workflow. Designed to process raw bulk materials into fine, highly uniform analytical samples, the equipment eliminates manual sampling bias while dramatically enhancing grain size reduction efficiency. By combining primary, secondary, and fine crushing stages with automated sub-sampling, this system provides material science and testing laboratories with an indispensable tool for fast, repeatable sample preparation.
The equipment is specifically optimized for processing brittle raw materials with compressive strengths not exceeding 80 MPa and moisture levels maintained below 6% to prevent material bridging. It excels across a wide range of industrial applications, including coal quality testing, metallurgical coke evaluation, limestone and cement raw mix analysis, phosphate mining, and geological assaying. Its robust construction ensures continuous, reliable operation even when processing abrasive minerals and tough industrial samples.
Built with heavy-duty structural steel and full-width high-manganese steel hammer assemblies, this system offers maximum operational reliability and long service life. Its fully sealed enclosure effectively contains all dust and fine particulates generated during high-speed impact crushing, protecting laboratory personnel and preventing cross-contamination between consecutive batches. Designed for effortless mobility and low maintenance, the unit provides industrial testing facilities with an exceptional balance of mechanical power, sampling precision, and operational safety.
Key Features
- Fully Sealed Environmentally Compliant Chamber: Constructed with a complete perimeter sealing structure that prevents dust and airborne particulates from escaping into the working area, maintaining pristine laboratory air quality while complying fully with strict environmental standards.
- Full-Width High-Manganese Steel Hammer Assembly: Features heavy-duty, wear-resistant high-manganese steel hammers extending across the full width of the rotor chamber, ensuring complete cross-sectional impact crushing, eliminating dead zones, and preventing chamber blockages.
- Integrated High-Precision Sample Divider System: Incorporates an automated mechanical division apparatus directly beneath the crushing discharge, splitting reduced material automatically at a standard 1:8 ratio or adjustable ranges from 1:4 to 1:16 to deliver exceptionally representative analytical samples.
- High Crushing Ratio with Uniform Granular Output: Delivers exceptional size reduction from feed inputs up to 140 mm down to tight granular fractions, yielding consistently rounded, well-distributed aggregate particles that simplify downstream fine grinding and assaying.
- Smooth Low-Vibration Rotary Drive: Utilizes dynamically balanced rotor assemblies and heavy-duty drive belts to maintain smooth kinetic operation, low operational noise levels, and minimal chassis vibration during heavy impact grinding cycles.
- Heavy-Duty Mobile Chassis with Locking Casters: Integrated onto a reinforced steel base frame equipped with high-load swivel casters, enabling effort-free repositioning across analytical laboratories and fast deployment wherever sample preparation is needed.
- Quick-Access Maintenance and Cleaning Design: Engineered with accessible side panels and smooth internal chamber geometry, allowing operators to quickly inspect, clean, or service internal grinding components between sample runs to prevent cross-contamination.
- Complete Transmission Safety Enclosures: Designed with full protective metal guards covering all drive belts, pulleys, and rotating shafts, guaranteeing complete operator protection in full alignment with industrial laboratory safety codes.
