Excessive coarse particles in PE rotomolding powder are not simply caused by insufficient grinding. This article explains how grinding conditions, component wear, feeding stability, temperature, and screening efficiency can affect the coarse fraction. It also shows how to identify the source of oversized particles and how Maoyue evaluates actual PE materials, pulverizing conditions, and screening results to achieve stable particle size and consistent powder quality.
PE rotomolding powder particle size can vary due to disc gap, blade wear, feeding, raw material characteristics, temperature, and screening conditions. This article explains the common causes and shows how process control, screening, and actual material testing can improve powder particle size stability.
This article explains how to evaluate plastic pulverizer blade wear resistance and service life using hardness, dimensional changes, cutting-edge wear, material throughput, powder particle size, and production data. It also covers controlled wear testing, wear-rate calculation, blade replacement criteria, and practical methods for comparing blade performance and operating costs.
