Attrition Dry Milling In Continuous And Batch Modes

The HSA Attritor is generally used in a continuous mode. The material is charged into the mill at the top by a pre-set rate feeder and discharged out the lower side of the grinding tank. HSA Series Attritors are generally used for finer feed material (-40 mesh), and produce large quantities of ultra fine

Attritor Stirred Ball Mill Sepor, Inc

Results are repeatable from one grind (batch) to another so the attritor is ideal for pilot plant and scale up studies. The material and media are agitated by a shaft with arms rotating at high speed. This causes the media to exert both shearing and impact forces on the material resulting in an extremely fine material.
