WhatsApp: +86 18838072829It has been estimated that grinding consumes up to 4% of global electrical energy and accounts for more than 50% of the total energy used in mining operations. In addition, more than 90% of the total energy supplied in beneficiation plants is dissipated as heat, kinetic energy, noise, and inefficient breakage of ores/raw material.

According to Alexander 119 and Kennedy et al. 120 maltodextrins are defined as nonsweet, nutritive starch hydrolysates (consisting of glucose units linked primarily by α14 bonds) with DE values less than 20.
WhatsApp: +86 18838072829Grinding is an indispensable step in mineral processing to reduce particles' size and liberate minerals before they are subjected to further separation processes. Grinding is characterized by high energy consumption and low energy efficiency (~ 1%) (Cheng et al. 2019; Liu et al. 1989; NapierMunn 2015).
