Fixing rollers gap in Pepe rolling mill

I have a Pepe rolling mill. Having loaned out my workshop I now find that the rollers, although parallel, do not meet together and have a gap of about .5mm between them. I can''t figure out how to raise and lower them independently of the turn screw at the top so that I can eliminate this gap. Anyone have an answer? Tony Konrath

Factors Affecting Rolling Pressure

The main factors affecting rolling pressure are: (1) Absolute rolling reduction. When the roll diameter and the friction coefficient are the same, with the increase of the absolute rolling reduction, the contact area between the rolled piece and the mill roll increases, and the rolling pressure increases.

Roller mills: Precisely reducing particle size with greater efficiency

Roller mill tests can help determine the right roll speed ratio for your material. Roll gap. Controlling the roll gap (Figure 3) is critical to achieving your required final particle size. This control has two components: the roll gap size and roll alignment. The roller mill

Rolling Mill Production Line: How to Adjust the Roll Gap?

 · After the rolling mill runs normally for 30 consecutive days, stop the rolling mill to check the meshing of the large and small gears. When everything is normal, the rolling speed can be increased. Under normal circumstances, there is no need to adjust the rolling speed. In the rolling mill, the rolls are constantly worn during operation.

Suggested gap in Econo mill rollers?

02-28-2011, 10:13 AM. Dave, We have been using an Apollo (4"x11" rollers) for about 5-6 years now. We actually gap our mill at about 1.65mm, however, that has more to do with our mash tun flow rate and base malt selection. I have taken it down to as low as 1.35mm, but experienced extremely slow run-offs.
