Product category : Machine tools
MikronsŪ attritors can be operated in both continuous and batch processing applications. In the batch mode, material is charged into the mill at the top, ground for a predetermined time, then discharged through valves at the bottom. No premixing is necessary. The material can be directly fed into the jacketed grinding tank of the attritor. Depending upon the application, electricals can be tefc [totally enclosed fan cooled] or explosion-proof.
The final result of the grinding action is a fine, even particle dispersion. The advantage here is that the material can be inspected any time during the grinding cycle. Therefore, adjustments or formulation additions can be accomplished without stopping the machine.
Attritors are ideal for long-term, heavy-duty, semi- and fully-automated production operations. They may also be used in conjunction with programmable controllers in highly sophisticated production environments.
The. MikronsŪ attritors are ruggedly built machines with specially designed, variable speed motor. They are also equipped with jackets and tilting devices for ease of cleaning and maintenance. MikronsŪ laboratory attritors are available from 0.5 litres to 50 litres.
Special options
Tank linings : special linings for metal-free grinding are available
Arm sleeves: to accommodate metal-free systems, shaft arms may be sleeved with plastic, tungsten carbide, or zirconium oxide.
MikronsŪ attritors are equipped with shaft seal to minimize solvent loss.
Torque meter: monitoring precise energy consumption
Drive : variable speed drives
Production batch are equipped with a built-in pumping system that maintains circulation during grinding for accelerated attrition and uniformity.
