High-performance mixing mills
Mixing Mills 2011
Our range of mixing mills includes machine designs and sizes to suit every requirement, either as a standard addition to a mixing line or for other specialized applications.
Our high-performance mixing mills feature the highest quality, reliability and profitability.
From the smallest to the largest sizes all the mixing mills made by Harburg-Freudenberger have the following quality features:
Base plate and machine frames
Welded to withstand high loads, the machine frames are positioned on the base plate using a key and keyway
arrangement and then bolted firmly into place. The machine frames and base plate are of ample proportions
for the loadings they carry.
Rolls
Chilled castings with a surface hardness of 510 ± 20 HB (Brinell) and burnished roll faces provide a smooth wear-resistant surface.
Roll cooling
Standard rolls are cored, cooling water being fed into the rolls via rotary unions and cooling pipes. The water also flows
back through these rotary unions, which are connected to feed and discharge lines by flexible hoses. On request, either the working roll or both rolls can be supplied with peripheral bores to ensure even more effective cooling of the compound.
