In cooperation with a German specialist, Shanghai IVA has invented a new type of classifier which has neither rotor nor motor. It is specially designed for classification of hard materials and working under high temperature conditions, such as classifying pure quartz, metal powder, carbon black …etc.
NEUMAN & ESSER roller mills are suitable for fine grinding of soft to medium hard materials, specifically light, adhesive and temperature sensitive materials. The throughput rates vary from 100 kg/h to 80 t/h depending on mill size, material and its fineness. Depending on the material, grinding and drying of material with a humidity of 35% is possible.
