Single discharge door for continuous or batching operation of …

1998/9/22 · The single continuous discharge door design is limited to a continuous mode of operation and cannot be used to mix discrete batches of materials. In the two door designs, the batch discharge rate through the shorter batch discharge door is slower than the discharge rate through the full length batch discharge door used on mixers dedicated to batch mode operation.

Understanding Discrete vs. Continuous Growth – BetterExplained

With enough splits, we could have smooth, continuous change. So, discrete changes can be modeled by some equivalent, smooth curve. What does it look like? The natural log finds the continuous rate behind a result. In our case, we grew from 1 to 2, which means our continuous growth rate was ln(2/1) = .693 = 69.3%.

2016/8/16 · I illustrated that exact matching on discrete covariates is the same as RA with fully interacted discrete covariates. Key to both methods is that the covariates are in fact discrete. If some collapsing of categories is performed as above, or if a discrete covariate is formed by cutting up a continuous covariate, all the results require that this combining step be performed correctly.
