Precision Toothed Roll Crusher for Laboratory Coal and Mineral Sample Preparation

Product Overview

This toothed roll crusher series is engineered specifically for precise and efficient size reduction of coal, minerals, and other soft to medium-hard materials in laboratory and pilot-scale settings. By pairing robust construction with advanced crushing mechanics, it consistently produces uniform particles with minimal fines, making it an essential tool for reliable sample preparation.

The equipment excels in applications where accurate and repeatable particle sizing is critical. Commonly used in coal quality analysis, mineral processing research, and building material testing, it serves a wide range of industries including mining, metallurgy, chemical processing, and environmental laboratories. Its adaptable design handles diverse feed materials with ease.

Designed with operator safety and long service life in mind, these crushers incorporate wear-resistant toothed rolls and a proven overload protection system. Engineered for continuous duty even when processing abrasive feedstock, they deliver dependable performance while maintaining low maintenance requirements.

Key Features

• High Crushing Capacity with Low Energy Consumption: The optimized tooth profile and roll speed maximize throughput—up to 600 kg/h on the larger model—while keeping motor power requirements modest, ensuring cost-effective operation.
• Integrated Overload Protection: A mechanical spring mechanism automatically releases and resets when uncrushable objects enter the rolls, preventing damage to the drive train and ensuring uninterrupted workflow in busy laboratories.
• Adjustable Roll Gap for Precise Sizing: By simply setting the gap between rolls, operators can control output particle size from 0.5 mm to 5 mm, accommodating a wide range of analytical preparation requirements without changing screens or sieves.
• Durable Wear-Resistant Rolls: Fabricated from SUS304 stainless steel, the rolls resist corrosion and abrasion, extending service intervals and maintaining crushing efficiency over thousands of operating hours.
• Compact, Low-Noise Operation: With a space-saving footprint and inherently quiet crushing action, this unit integrates seamlessly into crowded lab environments, minimizing disruption to sensitive instruments and personnel.
• Simple Structure and Easy Maintenance: The modular design allows quick access to rolls and bearings for cleaning, inspection, or replacement, reducing downtime and total cost of ownership.
• Uniform Particle Output: The combination of shearing and splitting forces creates a narrow particle size distribution, ideal for downstream analysis such as sieving, XRF, or proximate analysis.
• Reliable Direct Drive System: A high-efficiency electric motor coupled directly to the rolls delivers consistent torque and speed, ensuring stable performance even under varying load conditions.
