Small Hammer Crusher for Brittle Material Crushing in Mining Metallurgy and Lab Sample Preparation

Product Overview

This hammer crusher is a compact yet powerful sample preparation solution designed to reduce brittle materials to a fine, uniform size through a high-speed splitting impact mechanism. Unlike jaw crushers that primarily compress, this equipment uses rapidly rotating hammers to fracture material along natural grain boundaries, minimizing the production of ultra-fine dust and producing a more consistent particle shape. This makes it ideal for applications where precise particle size distribution is critical for downstream analysis.

Commonly deployed in quality control and R&D laboratories within the mining, metallurgy, and building materials sectors, the machine is capable of processing a wide variety of substances, from coal and coke to limestone and phosphate ores. Its adjustable sieve plate allows the operator to quickly set the desired output size (<3 mm) by simply swapping plates with different aperture sizes, ensuring flexibility to meet diverse analytical standards such as ASTM, ISO, or GB. During operation, material fed through the hopper is instantly struck by the rotating hammers and thrown against the crushing plates, being progressively reduced until small enough to exit through the sieve apertures.

Built to withstand demanding continuous use, the main body is offered in durable cast iron (for superior vibration damping) or welded steel (for maximum impact resistance). A 1.5 kW motor drives the balanced rotor through a V-belt, isolating the motor from crushing shocks. An elastic dust seal on the discharge chute and a manual feed gate on the hopper highlight the user‑focused design, ensuring safe, clean, and controlled operation. This equipment is a dependable workhorse for any laboratory requiring efficient size reduction.

Key Features

The following features define the performance and reliability of this crushing system:

• High-Efficiency Splitting Impact Crushing: Strategically shaped hammers mount on a dynamically balanced rotor, delivering concentrated impact forces that split brittle materials efficiently. This method reduces overgrinding and preserves sample integrity.
• Adjustable Output Size: Swappable sieve plates with various aperture dimensions enable on‑the‑fly particle size adjustment without the need for additional tools. This allows one machine to serve multiple sample preparation protocols.
• Robust and Compact Build: The heavy‑duty cast iron or welded steel frame provides a stable, space‑saving footprint that absorbs operational vibration and resists deformation even under intense use.
• Manual Feed Control: A hand‑operated gate valve on the feed hopper permits precise metering of input material, preventing blockages and protecting the motor from overload while optimizing crushing efficiency.
• Integrated Dust Suppression: An elastic sealing ring at the discharge coupling effectively contains fine particles within the crushing chamber, significantly reducing ambient dust and associated health risks.
• Wide Material Compatibility: Engineered to crush materials with compressive strengths up to 800 MPa, including coal, coke, limestone, phosphate rock, gangue, and pyrite. Custom hammer alloys and coatings are available for highly abrasive tasks.
• Simple Maintenance Regime: The open design grants quick access to all wear components—hammers, sieve plates, and liners—allowing fast replacement with basic hand tools, which minimizes downtime.
• Continuous-Duty Motor: The 1.5 kW TEFC motor is rated for non‑stop operation, with a V‑belt drive that shields it from impact forces, extending both motor and bearing life.
• Optimized Rotor Balancing: Factory dynamic balancing of the rotor assembly ensures minimal vibration at operating speed, reducing wear on bearings and enhancing operator comfort, which translates into longer service intervals.
• Interchangeable Wear Parts: All key wearing parts, including hammers and sieve plates, are designed for rapid replacement and are kept in stock for immediate delivery, ensuring uninterrupted operation.
