Product Overview
This drop shatter strength testing system delivers dependable mechanical resistance characterization for dense carbonaceous materials, including metallurgical coke, foundry coke, raw coal lumps, and formed industrial briquettes. Designed to rigorously simulate the severe dynamic impacts, kinetic transfers, and abrasive stresses experienced throughout bulk transport, railcar dumping, stockpile transfer chutes, and blast furnace charging, the equipment provides standardized, repeatable metrics of structural integrity. By quantifying the degradation and breakage behavior of solid carbon fuels under controlled free-fall impact, this apparatus allows processing facilities and research laboratories to establish precise shatter indices and safeguard downstream process efficiency.
Built for demanding deployment across metallurgical plants, commercial coking facilities, industrial briquetting operations, and quality inspection authorities, the testing unit accommodates high-throughput routine testing alongside specialized fuel development programs. The system streamlines testing workflows in accordance with national and international standard protocols, replacing labor-intensive and hazardous manual drop testing setups. Operating within heavy-duty industrial test environments, the machine isolates mechanical variability through motorized vertical hoists, rigid structural guidance, and instantaneous discharge mechanics, ensuring reliable data correlation across successive production batches.
Every structural member of this testing system is engineered to withstand tens of thousands of severe impact cycles without structural deflection or alignment distortion. Heavy-gauge carbon steel weldments, hardened impact receiving surfaces, high-torque geared drive assemblies, and dual-redundant safety limit controls guarantee uninterrupted operational longevity. Whether installed directly adjacent to screening plants or integrated into clean laboratory testing suites, the equipment maintains strict dimensional tolerances, smooth sample box elevation, and uniform kinetic impact geometry under rigorous around-the-clock testing schedules.
Key Features
- Precision Motorized Hoist Assembly: Driven by an industrial-grade 1.5 kW electric motor integrated with a high-efficiency worm gear reducer (1:50 reduction ratio), the elevating mechanism smoothly lifts fully loaded sample charges to standard drop elevations with stable velocity control.
- Standardized Drop Height Positioning: Engineered vertical lift geometry provides repeatable elevation settings at precisely 1830 mm for metallurgical coke evaluation and adjustable configurations reaching up to 2000 mm for industrial formed briquette characterization, complete with variable height stopping capabilities.
- Heavy-Plate Energy-Absorbing Base: The impact receiving bed is fabricated from a solid 12 mm thick high-tensile steel plate measuring 1220 mm by 965 mm, providing a true unyielding inertial foundation that eliminates rebound attenuation during impact events.
- Integrated Perimeter Containment Enclosure: A continuous 200 mm high carbon steel retaining wall borders the entire base perimeter, preventing particulate scatter, hazardous projectile expulsion, and fine material loss while preserving sample mass balance integrity.
- Automated Bottom-Discharge Release Mechanism: The specimen holding container features a rapid-actuating split-hinge bottom door system that opens instantaneously via mechanical trips, guaranteeing true vertical free fall without inducing initial rotational momentum or lateral wall drag.
- Heavy-Duty Welded Box Construction: The 710 mm × 455 mm × 380 mm sample container is fabricated from 3 mm thick structural steel plate with perimeter gusset reinforcements, preventing deformation under high-density bulk material loading.
- Dual Electro-Mechanical Travel Limiting: Upward and downward vertical travel paths are monitored by heavy-duty limit switches that prevent mechanical over-travel, ensuring operator safety and protecting the drive linkage from binding or overload conditions.
- Centralized Industrial Control Interface: The weather-resistant electrical enclosure incorporates push-button directional controls, clear status indicators, and an emergency stop circuit designed for rapid, intuitive operator control under dusty production conditions.
- Full Standards Alignment: Geometrical dimensions, drop clearances, structural rigidity, and discharge kinetics conform directly to testing methodologies specified under GB/T 4511.2-1999 and MT/T 925-2004 testing requirements.
