How to Grind Temperature-Sensitive Materials with Minimal Heat Generation

Introduction

Grinding temperature-sensitive materials presents unique challenges in industrial processing. Excessive heat generation during milling can degrade material properties, cause thermal decomposition, or even pose explosion risks. This article explores advanced techniques and equipment solutions to achieve efficient grinding while minimizing heat buildup, with a focus on ZENITH’s specialized grinding machinery.

Understanding Heat Generation in Grinding

The primary sources of heat in grinding operations include:

• Friction between grinding media and particles
• Plastic deformation of materials
• Inter-particle collisions
• Mechanical energy conversion
