Rolling mill- Air/Oil

Rolling mill air-oil automatic lubrication

In Rolling Mill applications, bearing temperatures are lower than casting applications, but rotation speed tend to be higher.
One system design characteristics is that the lubrication system has to cover a greater length due to the length of a roller section of a plant. 

For this reason, lubrication systems tend to be designed in a mixed fashion – a dual line system is used to cover the length of the rolling mill and then sub zones are made using Dropsa’s SMX Redbase Air/Oil volumetric distribution system.

Dropsa has been a pioneer of Air / Oil technology in such applications and is a strong promoter of volumetric technology in metering of micro oil quantities for these applications. 
Unlike other systems that have restrictive “splitter” devices to attempt to divide the air/oil mixture, the Dropsa volumetric approach allows you to have full assurance, with electronic monitoring and confirmation, that the exact amount of micro oil lubrication reaches every single point.  Many of our customers who have used splitter type devices in the past have been amazed by the performance they have achieved using volumetric Air/oil lubrication
