Low D/d (ratio of the vessel inner diameter to disc outer diameter) enables high impact force of beads to be maintained,resulting in high dispersion force. Variable disc tip speed control allows optimal disc-tip speed to be achieved, resulting in large centrifugal forces on the beads, thereby increasing the impact force and hence the wet-grinding and dispersion effects.

L/D RATIO The L/D ratio is the ratio of the flighted length of the screw to its outside diameter. The ratio is calculated by dividing the flighted length of the screw by its nominal diameter. Although several IMM manufacturers now offer a choice of injection units, most injection screws use a 20:1 L/D ratio. (The L/D ratio for extrusion

Compression Ratio: A Key Parameter of Pellet Mill

As the ratio of L1/d1 is equal to L2/d2, the compression ratio then consequently returns. In this way, the pellet quality is guaranteed and the lifespan of a die is extended. I have to repeat it again that the compression ratio is a dynamic parameter during pellet production for a pellet mill.

how can impact of l/d ratio on cement ball mill

The L/D ratio of the ball mill was varied in four steps of 1.75, 2.1, 2.79 and 3.49, and the ball charge filling ratio was varied in three steps of 15%, 20% and 25%. The experiments clearly indicated that the optimal L/D ratio and the optimal ball charge filling ratio are different for each feed fineness.

Consider L:D When Choosing A Lathe For Small Parts ...

Nov 15, 2007 · As a general rule, a Swiss-type is most appropriate for machining workpieces with L:D ratios of 4 to 1 or greater. Parts with lower L:D ratios may be machined economically on turn-mills. Some work delegated to Swiss-types might in fact be machined more efficiently on turn-mills, such as the Index C100 shown here.

What is Deep Hole Drilling

A deep hole is defined by its depth-to-diameter ratio (D:d), and typically holes greater than 10:1 are considered deep holes. Deep hole drilling into metal has a range of applications across several industries, with its origins tracing back to the need for straighter, more accurate gun barrels, and expanding as other industries integrated deep hole drilling processes to improve their own ...
