Known for several features such as fast and efficient grinding, easy operation, flexibility etc., our Laboratory Attritors are widely acclaimed by clients. Laboratory Attritors are used for obtaining homogenous and fine dispersions under controlled conditions. These Laboratory Attritors have a compact design, and are used for agriculture flowables, chemicals, ceramics, metal oxides etc. SF Attritor is used for producing fine & homogenous dispersons quickly & repeatedly under controlled conditions. Used for the manufacture of ceramics , inks, paints, coatings, metal oxides, ferrites, chocolates, chemicals & pharmaceuticals. The Attritor is often referred to as a agitated ball mill. The material to be ground is charged into a vertical tank filled with grinding media. Both the material and grinding media are then agitated by a shaft with arms causing the media to exert shearing & impact forces on the material. This action produces an extremely fine material measured in microns. No pre mixing is required. All attritors are provided with cooling jackets. Recirculating facility is available as optional. Attrition Mills, Also Called Stirred Ball Mills, Are A Very Fast, Powerful And Efficient Method For All Operations Of Grinding, Blending And Milling, Either Wet Or Dry. The Advantage Of An Attrition Mill Is That It Ensures That All The Grinding Media Are In Action All The Time. This Results In Much Faster Action.
