Product Overview
This unit is a high-speed hammer mill designed for small-scale coarse crushing of dry materials. It offers quick size reduction from large chunks to 2–20 mm particles, making it an ideal pre-processing tool for further fine grinding or direct use. The equipment excels in settings where a compact, easy-to-operate crusher is needed for multiple material types.
It is widely used in traditional Chinese medicine clinics, pharmacies, university research labs, and small production facilities for processing herbs, food ingredients, plastics, minerals, and other non-oily, non-sticky dry solids. With its continuous feeding and dust-controlled collection, the system streamlines sample preparation workflows.
Built with a robust direct-drive motor, hardened wear-resistant hammers, and a reinforced ring screen, this system ensures consistent output, low maintenance, and safe operation even under frequent batch cycles. Its thoughtful safety features and mobile design make it a reliable choice for demanding laboratory environments.
Key Features
- High-Hardness Wear-Resistant Hammers: Four sets of heat-treated hammers provide exceptional impact resistance and extended service life when crushing tough materials like roots, minerals, and plastic pellets.
- Direct-Drive Motor with Pure Copper Windings: A 2.2 kW single-phase motor connects directly to the main shaft, eliminating belt losses, reducing noise, and ensuring reliable start-up torque for frequent on-demand use.
- Thickened Ring Screen Design: The standard 8 mm sieve not only controls output size but also contributes secondary shearing and friction, improving overall crushing efficiency and throughput.
- Dual Safety Protections: A micro-switch on the crushing chamber lid cuts power when opened, while an integrated thermal relay protects the motor from overload and overheating.
- Arc-Shaped Hopper for Anti-Splash Feeding: The curved inlet guides material smoothly into the grinding chamber, preventing kickback and enabling safer continuous feeding.
- Mobile Base with Locking Casters: The entire unit sits on a sturdy frame with swivel wheels, allowing easy repositioning in crowded labs yet remaining stable during operation.
- Continuous Feeding and Dust-Controlled Discharge: Material is fed via a self-feeding hopper and collected in a filter bag, separating fines from exhaust air for a clean working environment.
Applications
