In the wet process, rotary cylinder ball mills, stirring mills, or sand mills are typically used. Today, larger-scale zircon processing plants mostly employ wet ball mills or stirred mills when the product size requirements are d50 <1.2μm and d97 ≤3μm. The production process for ball mills typically includes the following steps:
Pre-screening is the process of screening out the material with a qualifying particle size before crushing operations are carried out. This process is designed to avoid over-crushing of the material and to improve screening efficiency and reduce power consumption. Check screening is the process of sieving out the material after it h…
