1. PAINPOINT DRIVEN OPENING

Are you managing the recurring costs and operational inefficiencies of particle size reduction? Inconsistent feed materials, excessive wear part consumption, and unplanned maintenance stops directly impact your bottom line. Consider these common challenges:
High Operational Cost: Frequent replacement of hammers, screens, and liners due to standardgrade materials, coupled with high energy consumption per ton processed.
Production Bottlenecks: Downtime for sieve changes and maintenance reduces overall plant throughput, delaying downstream processes.
Inconsistent Output: Variable particle size distribution (PSD) due to wear or inadequate design, compromising product quality and creating issues in subsequent processing stages.
Excessive Vibration & Noise: Equipment that generates high vibration accelerates structural fatigue and creates noncompliance with workplace safety regulations.

How do you select a hammer mill that provides predictable operating costs, maximizes uptime, and delivers a consistent product grade? The solution lies in an OEMengineered design focused on total cost of ownership.

2. PRODUCT OVERVIEW

This content details a heavyduty OEM Hammer Mill designed for primary, secondary, or tertiary reduction of abrasive and nonabrasive materials in mining, aggregate production, and industrial mineral processing.

Operational Workflow:
1. Controlled Feed: Material is introduced via a regulated feed system (e.g., vibratory feeder, belt conveyor) into the grinding chamber.
2. Impact Reduction: Rotating hammers (swinging or rigid) impart kinetic energy to the material, fragmenting it against breaker plates and the chamber housing.
3. Size Classification: Processed material passes through a circumferential screen or grate; particles meeting the target size exit, while oversized particles are retained for further reduction.
4. Controlled Discharge: Sized material is conveyed away for further processing or storage.

Application Scope: Suitable for limestone, gypsum, coal, weathered shale, recycled aggregates, electronic scrap, and various ores. Not recommended for highly ductile metals (e.g., pure copper), very sticky materials without preconditioning, or extremely hard substances (above Mohs 89) where specialized crushers are more appropriate.
