A first survey of grinding with high-compression roller mills

Apr 01, 1988  A first survey of grinding with high-compression roller mills. Int. J. Miner. Process., 22: 401-412. The special feature of high-compression roller mills (HC-roller mills) is that a bed of particles is compressed between two rollers to a high solid density more than 70% of volume. The size reduction occurs by interparticle crushing.

Wet Compression Test Results Explained

The results of a compression test can be quite telling. The results shown below indicate the particular area that needs attention. Worn piston rings/cylinder walls: After running the first test, squirt a teaspoon of oil into the cylinder and rotate the crankshaft six more turns. If the compression increases, the piston rings are at fault.

On the unloaded mill there is no force before the slab or the strip arrives into the roll bite, therefore the gap has to be pre-set with an anticipated mill stretches. The anticipated mill stretch depends on the strip characteristics (size, material) and can be calculated using a high level system.
