In the world of industrial powder processing, few challenges are as persistent and critical as the grinding of temperature-sensitive materials. From pharmaceuticals and food products to certain chemicals and advanced materials, many substances undergo detrimental changes when exposed to excessive heat during the grinding process. These changes can include chemical degradation, loss of bioactive properties, altered physical characteristics, and reduced product quality.
The fundamental problem lies in the nature of grinding itself. Mechanical energy input during size reduction inevitably converts to thermal energy, leading to temperature rise. For conventional grinding equipment, this temperature increase can be substantial enough to compromise material integrity, particularly when dealing with substances that degrade at relatively low temperatures.
Temperature-sensitive materials typically have specific thermal thresholds beyond which their properties begin to deteriorate. Pharmaceutical compounds may lose potency, food ingredients can undergo flavor and nutritional degradation, while certain polymers might experience molecular breakdown or cross-linking. The challenge for grinding equipment manufacturers is to develop technologies that minimize heat generation while maintaining efficient particle size reduction.
Several factors contribute to temperature rise during grinding:
Modern grinding equipment addresses thermal challenges through multiple approaches. Integrated cooling systems, improved airflow design, and advanced material handling techniques work together to maintain optimal processing temperatures. The most effective solutions often combine several strategies:
For particularly challenging applications, Shanghai Zenith Machinery has developed specialized grinding systems that incorporate intelligent temperature control.
