Compression Ratio A Key Parameter of Pellet Mill

08 05 2014  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 And for each unique material the set compression

Rod Mill

Rod mills are used in an open circuit between crushing and the ball mill They often operate in wet and where the pulp contains up to 50 solid by mass This machine is equally very applicable to dry where it could take a feed that has achieved 6 moisture As such when the product is sticky rod mills are preferred over ball mills.

Answer Explanation Answer B minimise the effect of secondary forces Explanation The secondary unbalanced force is maximum when θ = 0° 90° 180° and 360° Thus the secondary force is maximum four times in one revolution of the crank Keeping large distance between connecting rod and crank minimises the effect of secondary forces.

Rod Lengths and Ratios

08 08 2016  Rod ratio is the mathematical relationship between the overall length of the connecting rods and the stroke of the crankshaft Divide rod length by the crank stroke and you get the rod ratio For example say you re building a stock small block 350 Chevy with 5.7 inch rods and a 3.48 inch stroke.

Answer Ratio between the connecting rod length and length of crank is taken more than unity as more the value of n ratio lower will be the value of secondary force

Stroker Motors Basics and Theory

Rod Ratio Rod to Stroke Ratio Rod Ratio or Rod to Stroke Ratio is the figure achieved when dividing a motor s rod length by its stroke This is an important calculation to understand since it informs us about a motor s rod angularity A low Rod Ratio yields a high rod angle.For example a motor with a 5.400 rod length and a 3.000 stroke yields a rod ratio of 1.8 1.
