Brochure ATR

Product catalog summary

Overview: The document discusses the Alpine ATR agitated ball mills, which are designed for the dry production of superfine mineral powders with particle sizes less than 10 µm. The technology ensures high energy efficiency and system reliability, making it cost-effective for producing products with fineness values up to 95% < 2 µm.

Applications: ATR mills are suitable for processing mineral fillers, glazing raw materials, and hard materials such as limestone, aluminium hydrate, quartz, zircon sand, talc, ceramic colours, frits, and titanium dioxide.

Example Configuration: A typical setup includes a soft CaCO3 feed of < 200 µm processed with a 900 ATR agitated ball mill and a 315/6 ATP classifier, driven by a 600 kW motor. The power consumption is 420 kW, with throughput rates of 700 kg/h at 90% < 2 µm and 3500 kg/h at 50% < 2 µm.

Grinding Process: The system includes components such as a feed bin, dosing screw, sieving machine, bucket elevator, agitated ball mill, turboplex classifier, rotary valve, automatic reverse-jet filter, butterfly valve, conveying screw, weighing bin, supply bin for grinding pearls, flap valve, fan, end product bin, sack filling and weighing unit, and process control.

Product Range: The document lists various ATR mill models with different drive power and dimensions, ranging from the 315 ATR with 18.5-37 kW to the 900 ATR with 315-450 kW.

Coating Capability: The mills can coat products during grinding, eliminating the need for additional grinding aids.

Materials and Linings: Depending on the product, linings made of aluminium oxide or other wearproof materials are used. Grinding beads between 2 mm and 5 mm in diameter ensure maximum energy intensity and effective surface enlargement.
