Feature
Using high-quality calcined bauxite both from local andShanxi, and processing after inspection, screening, to make high purity and fully calcined products
Adopting ultrafine ball-mill system, and advanced laser particle size detection control measures, for making high spherical degree, reasonable particle size distribution products, conducive to good workability of castables
