Small Hammer Crusher Fine Grinding Mill Laboratory Sample Preparation Rotary Hammer Crusher Machine

Product Overview

This small hammer crusher is an industrial-grade size reduction system designed for the primary, secondary, and fine crushing of raw bulk materials. Operating via high-velocity impact and precision blade shearing, the equipment transforms large mineral blocks and brittle compounds into uniform, regularly shaped granules with an exceptionally high reduction ratio. It provides precise, repeatable material preparation required for downstream processing and rigorous laboratory analytical procedures.

Engineered specifically for demanding mineral and geological workflows, the system processes a wide spectrum of materials, including coal, coke, limestone, pyrite, phosphate rock, coal gangue, and industrial glass. It efficiently handles raw material feeds with compressive strengths up to 100 MPa. The machine is widely adopted across metallurgical sampling stations, power generation testing labs, mining operations, and environmental testing facilities where physical sample integrity is critical.

Built with structural rigidity and ease of operation in mind, this equipment combines low-maintenance mechanical assemblies with heavy-duty internal wear components. Whether operating as a standalone benchtop or floor-mounted crushing unit or configured within an automated conveyor-fed analytical sample collection system, the unit ensures long-term reliability, low operational noise, and consistent discharge sizing under continuous duty cycles.

Key Features

• Dual Impact and Shearing Mechanism: Combines high-speed rotary hammer impact with heavy-duty blade shearing action, allowing the unit to efficiently process soft, hard, ductile, and brittle materials into tight particle size distributions.
• Alloy Tool Steel Hammer Blades: High-strength, high-hardness alloy tool steel construction on all active hammer blades delivers extreme resistance against abrasive wear, significantly extending operational lifespans and reducing downtime.
• Precision Discharge Granularity Control: Internal screen cages with customizable aperture sizes strictly govern final output dimensions, delivering discharge fractions from fine sub-3 mm powders up to 20 mm granules.
• Automated Conveyor Belt Feeding: Optional integrated belt conveyor systems driven by dedicated motor speed reducers deliver continuous, controlled material feed directly into the crushing chamber to prevent hopper blockage and uneven mechanical stress.
• Integrated Representative Sample Divider: Advanced system variants incorporate an automated 1/16 fixed mechanical reduction divider at the discharge conveyor tail, automatically extracting representative analytical samples for laboratory testing while routing bulk waste downstream.
• High Crushing Ratio Efficiency: Capable of accepting raw input sizes up to 200 mm and reducing them in a single pass, significantly streamlining sample preparation workflows and reducing total energy consumption.
• Robust Low-Vibration Engineering: Dynamically balanced rotor shafts and heavy-gauge structural steel frames minimize vibration, reduce noise generation, and protect internal bearings under heavy impact loads.
• Simplified Maintenance Access: Features modular housing covers and quick-release access panels that facilitate rapid inspection, screen cage replacement, and routine hammer maintenance.
