Coarse Powder Grinder – High-Efficiency Milling Solutions for Industrial Processing
Tired of Inefficient Material Size Reduction?
Struggling with inconsistent particle sizes, high energy costs, or frequent downtime in your mineral processing or aggregate operations? Traditional grinders often fail to deliver the throughput and uniformity required for coarse material handling—leading to production bottlenecks and wasted resources. .jpg)
Our Coarse Powder Grinder is engineered to solve these challenges, offering unmatched durability, precision, and efficiency for demanding industrial applications.
Product Overview: How Does It Work?
Designed for heavy-duty milling of minerals, aggregates, and industrial raw materials, this grinder employs a robust rotor-and-hammer system combined with advanced airflow classification to achieve uniform particle distribution (typically 0.5–5 mm). The workflow includes:
- Feed Intake: Material enters via a vibration-dampened hopper.
- Primary Crushing: High-impact hammers fracture coarse particles.
- Dynamic Screening: Adjustable grate bars control output size.
- Discharge: Classified powder exits via cyclone or baghouse systems.
Key Features & Innovations
- Heavy-Duty Construction: Reinforced alloy steel housing withstands abrasive materials like quartz, limestone, and slag.
- Adjustable Particle Control: Swap hammer configurations or grate bars in minutes—no tools required.
- Energy-Saving Design: Direct-drive motor reduces power consumption by up to 20% vs. belt-driven competitors.
- Low-Vibration Operation: Isolated bearings minimize wear and maintenance intervals.
