  Rod Lengths and Ratios

  08-08-2016 · Some engine builders say a “good” rod ratio is anything 1.55 or higher. Production engines may have rod ratios that range from 1.4 to over 2.0 with many falling in the 1.6 to 1.8 range. Four cylinders tend to have lower rod ratios (1.5 to 1.7 range) while many V6s have somewhat higher rod ratios of 1.7 to 1.8.

  Rod mills how they function

  Rod Mills How Do They Work? Rod mills are very similar to ball mills except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling the length to diameter ratio

  Grinding control strategy on the conventional milling

  the mill discharge from ball mill 1 will increase. With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase. This will decrease the ratio and hence the control loop will add more water to keep the ratio constant. However the amount of slurry reporting as fresh feed to the second milling circuit will increase.

  08-06-2010 · A convenient expression for the ratio is the Q value which is equal to the perce nt wall reduction divided by the percent ID reduction. A Q value of 2 or higher tends to smooth the ID surface. When the schedule does not lend itself to a series of high-Q-value draws it is better to use a high-Q-value rod draw followed by a hard sink rather than a series of low-Q-value drawing operations.
