Estimation of maximum crushing capacity of hammer mills

A study was made to correlate the maximum hold-up and mean residence time of hammer mills to the properties of raw materials. An empirical equation to estimate the maximum crushing capacity of hammer mills was obtained. The maximum crushing capacity measured was on an average about 1.5 times larger than the value calculated from the empirical

Residence time Wikipedia

The residence time of a fluid parcel is the total time that the parcel has spent inside a control volume (e.g.: a chemical reactor, a lake, a human body).The residence time of a set of parcels is quantified in terms of the frequency distribution of the residence time in the set, which is known as residence time distribution (RTD), or in terms of its average, known as mean residence time.

Calculating residence time FutureLearn

PROFESSOR RACHEL MILLS: So we know our bucket here is 10 litres and the water is flowing in at about a litre a minute. So we can calculate the average time a water molecule will spend in the bucket. It’s the volume of the bucket 10 divided by about a litre a minute. So the water spends 10 minutes in the bucket before it overflows over the side.

Feed Mill Efficiency Engormix

May 08, 2012 Roller mills are more energy efficient than hammer mills when grinding friable materials; the advantage for corn is <5% at sizes smaller than 500 microns, becomes 25-30% at 800 microns, and increases to perhaps >80% at a size of 3000 microns (CPM, 1992). The hammer mill (Figure 4) remains the industry standard for size reduction.
