Sealed Wet Coal Crusher High Moisture Sample Hammer Crusher System

Product Overview

Designed for rigorous laboratory sample preparation and high-throughput material processing, this sealed wet coal crusher provides efficient, reproducible size reduction for brittle bulk solids containing up to 20% moisture. The equipment combines a high-speed rotational hammer assembly with an active high-frequency vibrating mechanism to shatter incoming feed via high-impact splitting force. By preventing sample adhesion and screen bar blinding during processing, this system allows analytical laboratories, mining facilities, and fuel testing centers to process wet coal, coal gangue, coke, and limestone reliably without manual intervention or frequent shut-down cleanings.

Engineered specifically for demanding material science and industrial testing environments, this unit handles coarse, medium, and fine reduction tasks with high operational consistency. It accepts bulk feed sizes up to 80 mm and delivers controlled discharge sizing below 13 mm at processing capacities up to 2000 kg/h (2 metric tons per hour). The integrated two-stage screening design ensures that pre-existing fines bypass the main crushing chamber, reducing unnecessary mechanical wear, optimizing power consumption, and maintaining consistent sample integrity for downstream moisture and calorific value analyses.

Constructed within a heavy-duty, fully sealed enclosure mounted on four robust swivel casters, this sample preparation crusher isolates high-dust and high-impact operations from the surrounding lab environment. Capable of processing materials with compressive strengths up to 80 MPa, the heavy-duty rotor mechanism and wear-resistant alloy hammers provide long-term reliability and precise sample representation under rigorous operational demands. It represents a complete, dependable sample preparation solution that bridges industrial throughput with analytical precision.

Key Features

• High-Moisture Anti-Clogging Pre-Screening: An advanced vibrating mechanism drives the internal sieve plate up and down at high frequency, continually shaking fine, high-moisture particles through the grate bars into the sample receiver to prevent sticky coal slurry from building up or blinding the screen.
• High-Impact Splitting Rotor Assembly: The motor drives a heavy-duty 400 mm diameter rotor equipped with 16 wear-resistant hammers across 4 distinct groups, leveraging centrifugal force to extend the hammer heads outward and create a powerful impact ring that instantly splits brittle materials.
• Fully Sealed Dust-Tight Enclosure: The feeding mechanism, crushing chamber, vibrating screen assembly, and sample collection drawer are completely integrated into a dust-proof sealed housing, preventing dust escape, sample loss, and ambient moisture loss during sample processing.
• Two-Stage Particle Processing Architecture: High-moisture fine particles in the incoming raw feed are screened out immediately by the preliminary vibrating screen and drop directly into the sample receiver box, ensuring only oversized particles enter the main crushing zone for energy-efficient operation.
• Heavy-Duty Material Handling Capacity: Built to crush tough brittle minerals with compressive strengths up to 80 MPa, including hard coal, coal gangue, metallurgical coke, and limestone, ensuring reliable versatility across diverse geological and mineral samples.
• Continuous High-Capacity Processing: Delivers continuous throughput up to 2000 kg/h, significantly speeding up sample preparation workflows in high-volume testing facilities, central laboratories, and quality inspection stations.
• Mobile Ergonomic Base Design: The reinforced machine frame features four heavy-duty swivel casters, enabling flexible movement across laboratory floors, effortless placement near processing lines, and convenient access during routine maintenance.
• Uniform Particle Discharge Geometry: Engineered grate clearances ensure output particle sizes remain consistently under 13 mm with regular rounded geometries, maximizing sample representativeness for accurate sub-sampling, division, and analytical testing.
