Dry Grinding Attritors can be operated in Continuous or Batch operation. For a complete explanation of how Dry Grinding Attritors work in both Continuous and/or Batch operation, please download the Technical Paper “Attrition Dry Milling in Continuous and Batch Modes”




Model HSA-1 Laboratory Attritor

The HSA-1 High Speed Attritor is generally used in a continuous mode. The material is charged into these lab mills at the top and is discharged out the bottom side, making use of centrifugal force. The HSA is used when smaller particle size (generally 40 mesh) materials are fed into the machine and micron size end product is desired. Also, it is often used for fibrous and polymer types of materials.
