Frequently Asked Questions (FAQs)
- What is the typical fineness (mesh size) required for dolomite in ceramic bodies versus glazes?
For ceramic body applications, dolomite is often ground to between 200 and 400 mesh. For glaze applications, a much finer powder is required, typically ranging from 800 to 2500 mesh to ensure smooth application and optimal fusion. - How significant is energy consumption when selecting a dolomite pulverizer?
Extremely significant. Grinding is an energy-intensive process. Mills with 30-50% lower energy consumption, like some advanced vertical roller mills, can drastically reduce operational costs, which is a major competitive advantage in Bangladesh. - Why is iron contamination a concern in dolomite grinding for ceramics?
Iron impurities can cause discoloration (yellowing or graying) in white or brightly colored ceramic products. Modern mills with non-contact grinding principles or specialized wear materials are designed to minimize iron contamination. - Is dry grinding or wet grinding better for dolomite in ceramics?
Dry grinding is far more common for dolomite used as a raw material in ceramics due to lower overall operating costs, easier material handling, and no need for subsequent drying.
